[0002] Gas-liquid separation is very common in life and production. In life, for example, when a dehumidifier dehumidifies air, it uses the principle of gas-liquid separation. In production, such as in the brewing industry, gas-liquid separation is used to separate alcohol from the gas generated during distillation from air. However, the current gas-liquid separation method usually involves passing the gas through a refrigerant heat exchanger to cool the gas through the refrigerant heat exchanger, so that the liquid in the gas condenses out of the gas to reduce the humidity of the gas. This gas-liquid separation method not only has low gas-liquid separation efficiency, but also has relatively high energy consumption. Summary of the Invention

[0048] The realization and advantages of the functions of the present invention will be further described with reference to the embodiments and the accompanying drawings. Detailed implementation manners

[0049] The following will disclose multiple embodiments of the present invention in the form of diagrams. For the sake of clarity, many practical details will be described together in the following narrative. However, it should be understood that these practical details are not used to limit the present invention. That is to say, in some embodiments of the present invention, these practical details are unnecessary. In addition, for the purpose of simplifying the diagrams, some well-known and commonly used structures and components will be shown in a simple schematic manner in the diagrams.

[0050] It should be noted that all the directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly.

[0051] In addition, in the present invention, descriptions such as "first" and "second" are only for descriptive purposes, and do not particularly refer to the meaning of order or sequence, nor are they used to limit the present invention. They are merely used to distinguish components or operations described with the same technical terms, and should not be construed as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0052] To further understand the content, features and effects of the present invention, the following embodiments are exemplified and described in detail with reference to the accompanying drawings as follows:

[0053] Embodiment 1:

[0054] Please refer to Figure 1 and Figure 2 The gas-liquid separation component of this embodiment includes a refrigerant heat exchanger 1 and a first gas-gas heat exchanger 2. The first gas-gas heat exchanger 2 includes a first gas channel and a second gas channel, and the gas in the first gas channel exchanges heat with the gas in the second gas channel; and the airflow passing through the first gas channel exchanges heat with the refrigerant in the refrigerant heat exchanger 1 and / or the airflow after exchanging heat with the refrigerant in the refrigerant heat exchanger 1 passes through the second gas channel.

[0055] That is to say, when the gas-liquid separation component performs gas-liquid separation, the gas first enters the first gas channel of the first gas-gas heat exchanger 2, then flows from the first gas channel of the first gas-gas heat exchanger 2 to the refrigerant heat exchanger 1. After exchanging heat with the refrigerant in the refrigerant heat exchanger 1, the gas flows into the second gas channel of the first gas-gas heat exchanger 2. Since the gas in the second gas channel of the first gas-gas heat exchanger 2 is the gas after exchanging heat with the refrigerant in the refrigerant heat exchanger 1, there is a temperature difference between the gas in the second gas channel of the first gas-gas heat exchanger 2 and the gas in the first gas channel of the first gas-gas heat exchanger 2. Therefore, when there is gas passing through the first gas channel of the first gas-gas heat exchanger 2 and the second gas channel of the first gas-gas heat exchanger 2 has gas that has exchanged heat with the refrigerant heat exchanger 1 passing through, the gas in the first gas channel exchanges heat with the gas in the second gas channel.

[0056] In this embodiment, the temperature of the airflow passing through the first gas channel is higher than the temperature of the airflow passing through the second gas channel. The airflow in the first gas channel heats the airflow in the second gas channel; the refrigerant heat exchanger 1 reduces the temperature of the flowing airflow and generates condensed liquid to form saturated moist air; the temperature of the airflow passing through the second gas channel is lower than the temperature of the airflow passing through the first gas channel, and the airflow in the second gas channel precools the airflow in the first gas channel.

[0057] That is to say, when the gas is at the refrigerant heat exchanger 1, it is cooled by the refrigerant heat exchanger 1 and condensed into liquid, and then enters the second gas channel. Therefore, the gas entering the second gas channel is a low-temperature gas, while the gas entering the first gas channel is the gas before being processed by the refrigerant heat exchanger 1. Therefore, the temperature of the gas in the first gas channel is higher than the temperature of the gas in the second gas channel. When there is gas passing through the first gas channel of the first gas-gas heat exchanger 2 and there is gas passing through the second gas channel of the first gas-gas heat exchanger 2 after heat exchange with the refrigerant heat exchanger 1, the gas in the first gas channel heats the gas in the second gas channel, and at the same time, the gas in the second gas channel precools the gas in the first gas channel. In this way, the gas starts to be preliminarily separated into gas and liquid when it enters the first gas channel, which can reduce the working load at the refrigerant heat exchanger 1 and save energy consumption.

[0058] The refrigerant heat exchanger 1 cools the airflow and condenses the liquid in the airflow; the refrigerant heat exchanger 1 is a finned tube heat exchanger, which is bent into at least two sections. After the gas passes through one section, it then passes through another section; the temperature of the section that the gas passes through later is lower than the temperature of the section that the gas passes through first. The refrigerant heat exchanger 1 can contain refrigerant or water with a lower temperature inside. When the gas passes through the refrigerant heat exchanger 1, the refrigerant or water with a lower temperature cools the gas.

[0059] Since the refrigerant heat exchanger 1 and the first gas-gas heat exchanger 2 are arranged in parallel, taking the intake end of the first gas channel of the first gas-gas heat exchanger 2 as the starting end, the end of the refrigerant heat exchanger 1 close to the intake end of the first gas channel is the first section, and then along the flow direction of the gas in the first gas channel, they are successively recorded as the second section, the third section... Then, if the gas first passes through the first section of the refrigerant heat exchanger 1, the temperature of the first section is the highest, and the temperatures of the other sections gradually decrease, and the temperature of the section that the gas passes through last is the lowest; if the gas first passes through the last section of the refrigerant heat exchanger 1, the temperature of the last section is the highest, and the temperature of the first section is the lowest.

[0060] That is to say, when the gas-liquid separation component works, if the gas directly passes through the refrigerant heat exchanger 1 and is cooled and condensed into liquid by the refrigerant heat exchanger 1, at this time, the gas first passes through the first section of the refrigerant heat exchanger 1, and then passes through the second section in turn until the last section. At this time, the temperature of the first section of the refrigerant heat exchanger 1 is the highest, and the temperature of the last section is the lowest; if the gas first passes through the first gas channel of the first gas-gas heat exchanger 2 and then enters the refrigerant heat exchanger 1, at this time, the gas first passes through the last section of the refrigerant heat exchanger 1 and finally passes through the first section of the refrigerant heat exchanger 1. At this time, the temperature of the last section of the refrigerant heat exchanger 1 is the highest, and the temperature of the first section is the lowest.

[0061] Please review Figure 2 , such as Figure 2 As shown, in this embodiment, the gas-liquid separation component is provided with a regulating valve. The refrigerant heat exchanger 1 is V-shaped. One section of the refrigerant heat exchanger 1 close to the air inlet end of the first gas channel is the first section, and the other section is the second section. If the gas first passes through the first section of the refrigerant heat exchanger 1, the regulating valve makes the temperature of the first section of the refrigerant heat exchanger 1 higher than that of the second section. If the gas first passes through the second section of the refrigerant heat exchanger 1, the regulating valve makes the temperature of the first section of the refrigerant heat exchanger 1 lower than that of the second section.

[0062] Please review Figure 1 and Figure 2 , such as Figure 1 and Figure 2 As shown, in this embodiment, the gas-liquid separation component further includes a first gas valve assembly 3 and a second gas valve assembly 4. The first gas valve assembly 3 is used to allow the gas to enter from the first gas channel or / and the second gas channel or / and the refrigerant heat exchanger 1, and the second gas valve assembly 4 is used to allow the gas to be discharged from the second gas channel or / and the refrigerant heat exchanger 1.

[0063] That is to say, the first gas valve assembly 3 is used to open the air inlet of the first gas channel or / and the second gas channel and / or the refrigerant heat exchanger 1, and the second gas valve assembly 4 is used to open the air outlet of the first gas channel and / or the second gas channel or / and the refrigerant heat exchanger 1. By different combinations of the opening methods of the first gas valve assembly 3 and the second gas valve assembly 4, the gas-liquid separation component has different gas-liquid separation methods.

[0064] Please review Figure 1 and Figure 2 , such as Figure 1 and Figure 2As shown, the first gas valve assembly 3 is a gas valve that can be switched by rotating left and right. It includes a first gas valve drive motor 31, a first gas valve drive shaft 32, a first gas valve 33, and a first gas valve partition 34. The first gas valve drive motor 31 is provided on the first gas valve partition 34. There are rotating shaft seats on both sides of the first gas valve partition 34. The first gas valve drive shaft 32 is rotatably connected to the rotating shaft seats, and one end thereof extends out of the rotating shaft seat and is connected to the drive end of the first gas valve drive motor 31. The first gas valve 33 is connected to the first gas valve drive shaft 32. When the first gas valve drive motor 31 drives the first gas valve drive shaft 32 to rotate counterclockwise, the first gas valve 33 rotates to the right along with the first gas valve drive shaft 32, causing the first gas valve partition 34 to move away from the air inlet of the first gas channel of the first gas-gas heat exchanger 2, and at the same time approaching the air inlet of the second gas channel of the first gas-gas heat exchanger 2 and the air port at the first section close to the refrigerant heat exchanger 1, and closing the air inlet of the second gas channel of the first gas-gas heat exchanger 2 and the air port at the first section close to the refrigerant heat exchanger 1, so that gas can enter the first gas channel of the first gas-gas heat exchanger 2. When the first gas valve drive motor 31 drives the first gas valve drive shaft 32 to rotate clockwise, the first gas valve 33 rotates to the left along with the first gas valve drive shaft 32, causing the first gas valve partition 34 to close the air inlet of the first gas channel, and at the same time opening the air inlet of the second gas channel of the first gas-gas heat exchanger 2 and the air port at the first section close to the refrigerant heat exchanger 1, so that gas can flow through the second gas channel of the first gas-gas heat exchanger 2 or / and the refrigerant heat exchanger 1. When any one of the air inlet of the first gas channel of the first gas-gas heat exchanger 2, the air inlet of the second gas channel, and the air port at the first section close to the refrigerant heat exchanger 1 is closed by the first gas valve 33, the first gas valve drive motor 31 drives the first gas valve drive shaft 32 to rotate, and when it rotates to half of the angle required to close the other air inlet / air port, at this time, the air inlet of the first gas channel of the first gas-gas heat exchanger 2, the air inlet of the second gas channel, and the air port at the first section close to the refrigerant heat exchanger 1 are all opened.

[0065] Please review Figure 1 and Figure 2 , such as Figure 1 and Figure 2As shown in the figure, the second valve assembly 4 includes a second valve partition plate 41, a slide rail 42, a slider 43, a second valve 44, and a second valve drive motor 45. The second valve partition plate 41 is arranged at the first gas passage, the second gas passage of the first gas-gas heat exchanger 2, and the air outlet of the refrigerant heat exchanger. An upper outlet 411 and a lower outlet 412 are provided on the second valve partition plate 41. The upper outlet 411 is aligned with the air outlet of the first gas passage and the air port near the second section of the refrigerant heat exchanger 1. The lower outlet 412 is aligned with the air outlet of the second gas passage. Slide rails 42 are provided on both sides of the second valve partition plate 41. The slider 43 is slidably connected within the slide rail 42. The second valve 44 is connected to the slider 43. The second valve drive motor 45 is arranged on one side of the second valve partition plate 41, and its drive end is connected to the slider 43 on the corresponding side. The second valve drive motor 45 can drive the slider 43 to move upward along the slide rail 42 to open the air outlet of the second gas passage by the second valve 44, or drive the slider 43 to move downward along the slide rail 42 to open the air outlet of the first gas passage and the air port near the second section of the refrigerant heat exchanger 1 by the second valve 44, or move the slider 43 to the middle position of the slide rail 42 to open the air outlets of the first gas passage, the second gas passage of the first gas-gas heat exchanger 2, and the air port near the second section of the refrigerant heat exchanger 1 simultaneously by the second valve 44.

[0066] In this embodiment, the gas-liquid separation mode of the gas-liquid separation assembly includes a first mode. In the first mode, the air flow passing through the first gas passage exchanges heat with the refrigerant in the refrigerant heat exchanger 1, and the air flow after heat exchange with the refrigerant passes through the second gas passage.

[0067] Please review Figure 2 , such as Figure 2As shown, that is to say, in the first mode, the first gas valve assembly 3 opens the air inlet of the first gas channel of the first gas-gas heat exchanger 2, and at the same time closes the air inlet of the second gas channel of the first gas-gas heat exchanger 2 and the air port near the first section of the refrigerant heat exchanger 1. The second gas valve assembly 4 closes the air outlet of the first gas channel of the first gas-gas heat exchanger 2 and the air port near the second section of the refrigerant heat exchanger 1. The gas enters from the air inlet of the first gas channel of the first gas-gas heat exchanger 2, flows through the first gas channel to the air outlet of the first gas channel, and then enters the refrigerant heat exchanger 1 from the air port near the second section of the refrigerant heat exchanger 1. When passing through the refrigerant heat exchanger 1, it first passes through the second section of the refrigerant heat exchanger 1, then passes through the first section of the refrigerant heat exchanger 1, and then flows out from the air port near the first section of the refrigerant heat exchanger 1. The gas flowing out from the air port near the first section of the refrigerant heat exchanger 1 enters the second gas channel of the first gas-gas heat exchanger 2 through the air inlet of the second gas channel of the first gas-gas heat exchanger 2, then flows along the second gas channel to the air outlet of the second gas channel, and flows out from the air outlet of the second gas channel. In the first mode, the temperature of the first section of the refrigerant heat exchanger 1 is lower than the temperature of the second end of the refrigerant heat exchanger. Therefore, the gas flowing out from the air port near the first section of the refrigerant heat exchanger 1 is the gas after cooling and condensing out the liquid in the refrigerant heat exchanger 1, and the temperature of this gas is the lowest. When this gas enters the second gas channel of the first gas-gas heat exchanger 2, it can pre-cool the gas in the first gas channel of the first gas-gas heat exchanger 2, so that the gas in the first gas channel of the first gas-gas heat exchanger 2 is cooled and condensed out the liquid. At the same time, the gas in the first gas channel of the first gas-gas heat exchanger 2 heats the gas in the second gas channel of the first gas-gas heat exchanger 2.

[0068] The gas-liquid separation assembly further includes a second mode. In the second mode, the first gas valve assembly 3 opens the air inlet of the first gas channel, the air inlet of the second gas channel, and the air port near the first section of the refrigerant heat exchanger 1. The second gas valve assembly 4 opens the air outlet of the first gas channel of the first gas-gas heat exchanger 2, the air outlet of the second gas channel, and the air port near the second section of the refrigerant heat exchanger 1. After part of the gas passes through the first gas channel and / or the second gas channel of the first gas-gas heat exchanger 2, it is mixed with part of the gas that has been cooled and had the liquid condensed out in the refrigerant heat exchanger 1.

[0069] Please review Figure 2 , such as Figure 2As shown, that is to say, in the second mode, there are three flow directions of the gas when passing through the gas-liquid separation component. Flow direction 1: Part of the gas passes through the refrigerant heat exchanger 1, and the other part passes through the first gas passage of the first gas-gas heat exchanger 2. The gas passing through the first gas passage of the first gas-gas heat exchanger 2 is mixed with the gas that has been cooled and condensed into liquid by the refrigerant heat exchanger 1. Flow direction 2: Part of the gas passes through the refrigerant heat exchanger 1, and the other part passes through the second gas passage of the first gas-gas heat exchanger 2. After the gas passing through the second gas passage of the first gas-gas heat exchanger 2 is mixed with the gas after passing through the refrigerant heat exchanger 1. Flow direction 3: Part of the gas passes through the refrigerant heat exchanger 1, part passes through the first gas passage of the first gas-gas heat exchanger 2, and part passes through the second gas passage of the first gas-gas heat exchanger 2. The gas passing through the first gas passage of the first gas-gas heat exchanger 2, the gas passing through the second gas passage of the first gas-gas heat exchanger 2 is mixed with the gas that has been cooled and condensed into liquid after passing through the refrigerant heat exchanger 1.

[0070] Please review Figure 2 , such as Figure 2 As shown, in the case of Flow direction 1, the first gas valve assembly 3 opens the air inlet of the first gas passage, the air inlets of the second gas passage and the air port near the first section of the refrigerant heat exchanger 1 at the same time. The second gas valve assembly 4 opens the air outlet of the first gas passage of the first gas-gas heat exchanger 2 and the air port near the second section of the refrigerant heat exchanger 1. Part of the gas passes near the refrigerant heat exchanger 1, and the other part of the gas enters the first gas passage through the air inlet of the first gas passage of the first gas-gas heat exchanger 2. The gas passing through the first gas passage of the first gas-gas heat exchanger 2 is discharged from the air outlet of the first gas passage. The gas that has been cooled and condensed into liquid by the refrigerant heat exchanger 1 is discharged from the air port near the second section of the refrigerant heat exchanger 1 and is mixed with the gas discharged from the air outlet of the first gas passage of the gas heat exchanger 2.

[0071] Please review Figure 2 , such as Figure 2 As shown, in the case of Flow direction 2, the first gas valve assembly 3 opens the air inlet of the second gas passage and the air port near the first section of the refrigerant heat exchanger 1 at the same time. The second gas valve assembly 4 opens the air outlet of the second gas passage of the first gas-gas heat exchanger 2 and the air port near the second section of the refrigerant heat exchanger 1. Part of the gas enters the refrigerant heat exchanger 1 from the air port near the first section of the refrigerant heat exchanger 1 and then is discharged from the air port near the second section of the refrigerant heat exchanger 1. The other part of the gas enters the second gas passage through the air inlet of the second gas passage of the first gas-gas heat exchanger 2 and is discharged from the air outlet of the second gas passage after passing through the second gas passage of the first gas-gas heat exchanger 2 and is mixed with the gas flowing out from the air port near the second section of the refrigerant heat exchanger 1.

[0072] Please review Figure 2 , as Figure 2 shown, in the third direction, when the first gas valve assembly 3 opens the inlet of the first gas passage, the inlets of the second gas passage and the gas port near the first section of the refrigerant heat exchanger 1 simultaneously, and the second gas valve assembly 4 opens all the outlets of the first gas passage, the second gas passage of the first gas-gas heat exchanger 2 and the gas port near the second section of the refrigerant heat exchanger 1, a part of the gas enters the refrigerant heat exchanger 1 through the gas port near the first section of the refrigerant heat exchanger 1 and is discharged through the gas port near the second section of the refrigerant heat exchanger 1. A part of the gas enters the first gas passage from the inlet of the first gas passage of the first gas-gas heat exchanger 2 and is discharged from the outlet of the first gas passage. A part of the gas enters the second gas passage through the second gas passage of the first gas-gas heat exchanger 2 and is discharged from the outlet of the second gas passage. The gas discharged from the outlet of the first gas passage of the first gas-gas heat exchanger 2, the gas discharged from the outlet of the second gas passage of the first gas-gas heat exchanger 2 and the gas discharged from the gas port near the second section of the refrigerant heat exchanger 1 are mixed.

[0073] That is to say, in the second mode, by adjusting the states of the first gas valve assembly 3 and the second gas valve assembly 4, it can be determined that the gas cooled and condensed into liquid by the refrigerant heat exchanger 1 comes from the first gas passage and / or the second gas passage of the first gas-gas heat exchanger 2.

[0074] The gas-liquid separation assembly of this embodiment further includes a third mode. In the third mode, the first gas valve assembly 3 is in a state that allows gas to enter from the refrigerant heat exchanger 1, and the second gas valve assembly 4 is in a state that allows gas to be discharged from the refrigerant heat exchanger 1; the gas flows through the refrigerant heat exchanger, is cooled and condensed to generate condensed liquid, and then is discharged.

[0075] Please review Figure 2 , as Figure 2 shown, that is to say, in the third mode, the first gas valve assembly 3 opens the gas port near the first section of the refrigerant heat exchanger 1 simultaneously, and the second gas valve assembly 4 opens the gas port near the second section of the refrigerant heat exchanger 1. The gas enters the refrigerant heat exchanger 1 through the gas port near the first section of the refrigerant heat exchanger 1, is cooled by the refrigerant heat exchanger 1 and condensed to generate condensed liquid, and then is discharged through the gas port near the second section of the refrigerant heat exchanger 1.

[0076] The gas-liquid separation assembly further includes a fourth mode. In the fourth mode, the first gas valve assembly 3 is in a state that allows air to enter from the second gas passage of the first gas-gas heat exchanger 2, and the second gas valve assembly 4 is in a state that allows air to be discharged from the second gas passage of the first gas-gas heat exchanger 2. The air passes through the second gas passage of the first gas-gas heat exchanger 2 and then is discharged.

[0077] Please review Figure 2 , as Figure 2 shown, that is to say, in the fourth mode, the first gas valve assembly 3 opens the air inlet of the two-gas channel of the first gas-gas heat exchanger 2, and the second gas valve assembly 4 opens the air outlet of the second gas channel of the first gas-gas heat exchanger 2. The gas enters the second gas channel from the air inlet of the second gas channel of the first gas-gas heat exchanger 2, passes through the second gas channel, and is discharged from the exhaust port of the second gas channel.

[0078] In this embodiment, the first gas-gas heat exchanger 2 can be a total heat exchanger or a sensible heat exchanger. When a total heat exchanger is used, the gas not only exchanges temperature but also exchanges humidity when passing through the first gas-gas heat exchanger 2. When a sensible heat exchanger is used, the gas can only exchange temperature and cannot exchange humidity when passing through the first gas-gas heat exchanger 2, and can be preliminarily dehumidified when passing through the first gas channel of the first gas-gas heat exchanger 2. In this embodiment, the first gas-gas heat exchanger 2 is a sensible heat exchanger. The air in the first gas channel and the second gas channel of the first gas-gas heat exchanger 2 only exchanges heat and does not exchange moisture, and can be preliminarily dehumidified when passing through the first gas channel of the first gas-gas heat exchanger 2. The gas cooled and dehumidified by the refrigerant heat exchanger 1 is only preheated by the air in the first gas channel of the first gas-gas heat exchanger 2 when passing through the second gas channel of the first gas-gas heat exchanger 2.

[0079] The gas-liquid separation assembly of this embodiment can be used in the brewing industry. In the brewing industry, grains are fermented and distilled, and the gas produced by distillation contains alcohol. At this time, the gas containing alcohol is passed through the gas-liquid separation assembly of this embodiment for gas-liquid separation, and the alcohol is condensed into a liquid.

[0080] When it is necessary to perform gas-liquid separation of alcohol and gas, any of the above-mentioned modes can be adopted. When the gas contains a relatively high amount of alcohol, the first mode can be adopted for gas-liquid separation; the gas containing alcohol first enters the first gas channel of the first gas-gas heat exchanger 2 through the air inlet of the first gas channel, and then is discharged from the air outlet of the first gas channel of the first gas-gas heat exchanger 2. The discharged gas enters the refrigerant heat exchanger 1 through the air port near the second section of the refrigerant heat exchanger 1. The gas after being cooled and condensed to produce alcohol in the refrigerant heat exchanger 1 is discharged from the air port near the first section of the refrigerant heat exchanger 1. The discharged gas enters the second gas channel of the first gas-gas heat exchanger 2 through the air inlet of the second gas channel and is discharged from the air outlet of the second gas channel after passing through the second gas channel. When the gas passes through the second gas channel, since the gas is at a relatively low temperature after being cooled by the refrigerant heat exchanger 1, the gas in the second gas channel can pre-cool the gas in the first gas channel, so that the gas is cooled when passing through the first gas channel and starts to condense out alcohol.

[0081] The gas discharged from the air outlet of the second gas channel can enter the next distillation process for heating up, and then pass through the gas-liquid separation assembly of this embodiment again for alcohol separation. The second mode is adopted for gas-liquid separation, and preliminary gas-liquid separation is carried out in the first gas channel, which can reduce the load at the refrigerant heat exchanger 1 and improve the efficiency of gas-liquid separation.

[0082] In practical applications, a water receiving tray is provided at the air inlet or / and air outlet of the first gas channel of the first gas-gas heat exchanger 2 of the gas-liquid separation assembly, and a water receiving tray is also provided below the refrigerant heat exchanger 1. The condensed alcohol can enter the water receiving tray and then be led out through a drainage device for collecting the alcohol.

[0083] Embodiment 2:

[0084] The present invention also provides an air treatment device, which is provided with this gas-liquid separation assembly, and the air treatment device can dehumidify the air by adopting any one of the four gas-liquid separation modes of the gas-liquid separation assembly.

[0085] Please refer to Figures 3 to 5 ., as Figures 3 to 5As shown in the figure, the air handling device includes a housing 5, a fresh air fan 6, a circulation fan 7, a gas-liquid separation component, and a bypass valve 8. Inside the housing 5, there are a fresh air inlet 51, a supply air outlet 52, a circulation air inlet 53, a fresh air duct, and a circulation duct. The fresh air duct connects the fresh air inlet 51 and the supply air outlet 52, and the circulation duct connects the circulation air inlet 53 and the supply air outlet 52. The fresh air fan 6 is arranged in the fresh air duct, the circulation fan 7 is arranged in the circulation duct, and the gas-liquid separation component is arranged in the fresh air duct. The first gas-gas heat exchanger 2 and the refrigerant heat exchanger 1 of the gas-liquid separation component are arranged in parallel in the fresh air duct and are located between the fresh air fan 6 and the supply air outlet 52. The bypass valve 8 is arranged between the fresh air duct and the exhaust duct and is used to connect or block the fresh air duct and the circulation duct. The fresh air intake modes of the gas-liquid separation component include: Mode 1: The bypass valve 8 is closed, and the fresh air fan 6 drives outdoor fresh air to enter the fresh air duct from the fresh air inlet 51 and flow towards the gas-liquid separation component; Mode 2: The bypass valve 8 is opened, and the circulation fan 7 drives outdoor fresh air to enter the circulation duct from the fresh air inlet 51 and flow towards the gas-liquid separation component.

[0086] In this embodiment, the fresh air inlet 51 is connected to the outdoor environment, and the circulation air inlet 53 and the supply air outlet 52 are connected to the indoor environment or indoor air ducts. The fresh air duct and the circulation duct are independent of each other, and the fresh air fan 6 and the circulation fan 7 also operate independently of each other. The fresh air duct and the circulation duct are connected or blocked by the bypass valve 8, and different fresh air introduction paths can be realized by the opening and closing of the bypass valve 8 and the opening and closing of the fans.

[0087] When the bypass valve 8 is closed, the fresh air introduction method at this time is to turn on the fresh air fan 6. The fresh air fan 6 drives outdoor fresh air to enter the fresh air duct through the fresh air inlet 51, and then flows into the gas-liquid separation component from the fresh air duct. In Mode 1, the circulation fan 7 in the circulation duct can be turned on or off, which has no impact on the fresh air introduction. Mode 1 is applicable to the situation where the indoor air is in a slightly negative pressure or medium negative pressure state. For example, when the range hood is operating at a low gear or only a small number of exhaust fans are turned on, an appropriate amount of fresh air is supplemented into the room to ensure the air pressure balance between indoors and outdoors.

[0088] When the bypass valve 8 is opened, the fresh air duct and the circulation duct are connected at this time. Only by turning on the circulation fan 7, it can drive outdoor fresh air to enter the circulation duct in sequence through the fresh air inlet 51 and enter the gas-liquid separation component from the circulation duct, which is the above-mentioned Mode 2. Mode 2 is also applicable to the situation where the indoor air is in a slightly negative pressure or medium negative pressure state. For example, when the range hood is operating at a low gear or only a small number of exhaust fans are turned on, an appropriate amount of fresh air is supplemented into the room to ensure the air pressure balance between indoors and outdoors.

[0089] The fresh air intake mode of the air-liquid separation component also includes Mode 3: The bypass valve 8 is opened, and the fresh air fan 6 and the circulation fan 7 drive the outdoor fresh air to enter from the fresh air inlet 51 at the same time, and flow through the fresh air duct and the circulation duct to the air-liquid separation component.

[0090] That is to say, when the bypass valve 8 is opened, the fresh air fan 6 and the circulation fan 7 are turned on at the same time. After driving the outdoor fresh air to enter from the fresh air inlet 51, a part of the fresh air flows from the fresh air duct to the air-liquid separation component, and another part of the fresh air enters the circulation duct under the action of the circulation fan 7 and flows from the circulation duct to the air-liquid separation component. At this time, the fresh air intake volume is jointly driven by the fresh air fan 6 and the circulation fan 7. Mode 3 is applicable to the situation where the indoor air is in a medium negative pressure or high negative pressure state, such as when the range hood is operating at medium / high gear or a large number of exhaust fans are turned on, or when the range hood and the exhaust fans are operating at the same time, a large amount of fresh air is supplied to the room to ensure the air pressure balance between indoors and outdoors.

[0091] Please review Figure 3 , such as Figure 3 As shown in the figure, in this embodiment, a fresh air valve 61 is provided at the air outlet of the fresh air fan 6, and a circulation air valve 71 is provided at the circulation air inlet 53. The fresh air valve 61 is used to connect or close the fresh air duct and the air-liquid separation component, and the circulation air valve 71 is used to connect or close the circulation air inlet 53 and the circulation duct.

[0092] That is to say, in Mode 3, the fresh air valve 61 is in the open state. When introducing fresh air by using the circulation fan 7, the circulation air valve 71 at the circulation air inlet 53 can be in the closed state or the open state. When it is in the closed state, the air flow driven by the circulation fan 7 is all fresh air introduced from the outside, ensuring the fresh air intake volume. When it is in the open state, at this time both the circulation air inlet 53 and the bypass valve 8 are opened, then the circulation fan 7 can drive both indoor air and outdoor fresh air to enter the circulation duct. After the outdoor fresh air and the indoor fresh air are mixed and heat-exchanged in the circulation duct, they are then introduced into the indoor environment from the air supply outlet 52, which can reduce the temperature impact on the air supply outlet 52. This method is applicable to the situation where the demand for fresh air replenishment is small.

[0093] Of course, when the bypass valve 8 is open, the fresh air damper 61 and the recirculated air damper 71 can also be closed. At this time, the recirculating fan 7 drives outdoor fresh air into the recirculation air duct, and then the air flows from the recirculation air duct to the gas-liquid separation assembly. This situation is the same as when the bypass valve is closed, allowing fresh air to enter the fresh air duct from the fresh air inlet 51 and then flow from the fresh air duct to the gas-liquid separation assembly. However, when there is a total heat exchanger downstream of the fresh air passage and the indoor temperature is similar to the outdoor temperature, the fresh air does not need to pass through the total heat exchanger for heat exchange and flow to the gas-liquid separation assembly. At this time, the bypass valve 8 can be opened, and then the fresh air damper 61 and the recirculated air damper 71 can be closed, so that the fresh air directly flows to the gas-liquid separation assembly through the recirculation air duct. For example, when the range hood in the kitchen is operating and creating a negative pressure in the kitchen, fresh air can be directly extracted, dehumidified, and introduced into the negative pressure area of the kitchen, improving the working efficiency of the range hood and simultaneously improving the air quality in the kitchen.

[0094] Of course, when the bypass valve 8 is closed, the recirculating fan 7 can also be turned on alone without turning on the fresh air fan 6. This method can be used when the air pressures in different areas of the room are different. For example, when the range hood in the kitchen is operating and the air volume in the living room is large, the air in the living room can be driven by the recirculating fan 7 through the recirculation air outlet 53 and flow from the air supply outlet 52 to the air duct connected to the kitchen, so as to supplement the air flow in the living room with a large air volume into the kitchen in a negative pressure state, thereby ensuring the air pressure stability in the kitchen according to the air volume distribution between different areas in the room and improving the working efficiency of the range hood.

[0095] It can be understood that the structural form of the bypass valve 8 can be determined according to the actual situation. For example, it can be a door structure, a spherical structure, or a needle structure, etc. Different structural forms have different adjustment methods. For example, the door structure can be adjusted by sliding or rotating drive, the spherical structure can be adjusted by rotating drive, and the needle structure can be adjusted by sliding drive, etc. The specific adjustment effect needs to be determined according to the actual demand for fresh air flow. The installation position of the bypass valve 8 can also be determined according to the actual situation. For example, it can be installed on the air inlet side of the recirculating fan 7 and / or the fresh air fan 6, or on the air outlet side of the recirculating fan 7 and / or the fresh air fan 6, or on the air inlet side of the recirculating fan 7 and the air outlet side of the fresh air fan 6, etc. Its specific position can be determined according to the internal structure layout of the air handling device.

[0096] Please review Figure 3 ,such as Figure 3 As shown, in this embodiment, the housing 5 is also provided with an indoor air outlet 54 and an outdoor air outlet 55. An exhaust air duct communicating with both the indoor air outlet 54 and the outdoor air outlet 55 is formed inside the housing 5, and an exhaust fan 9 is provided in the exhaust air duct.

[0097] That is to say, on the basis of supplying fresh air into the room, when the fresh air supplied into the room is sufficient or excessive, it may affect the temperature / humidity of the indoor air. Then, the exhaust fan 9 can be turned on to drive the indoor air to enter the exhaust air duct from the indoor air outlet 54 and then be discharged to the outdoor air outlet 55. While ensuring the air pressure balance between the indoor and outdoor, the function of indoor air ventilation can be realized, and the indoor air quality can be improved.

[0098] Of course, in the actual application process, it can also be that when the indoor air quality is poor, such as when the range hood in the kitchen fails, the exhaust fan in the bathroom fails, or the indoor air becomes turbid due to other reasons, the exhaust mode can be turned on to discharge the indoor polluted air. Optionally, when the air pressure between the indoor and outdoor is almost balanced but the indoor air quality is poor, fresh air can be introduced in Mode 1, that is, the bypass valve 8 is closed, the fresh air fan 6 is turned on to introduce fresh air, and at the same time the exhaust fan 9 is turned on for exhaust, or fresh air can be introduced in Mode 2, that is, the bypass valve 8 is opened, the circulating fan 7 is used to introduce fresh air, and at the same time the exhaust fan 9 is turned on for exhaust, so as to realize the function of indoor air ventilation when the air pressure between the indoor and outdoor is balanced.

[0099] Please review Figure 3 , such as Figure 3 As shown, in order to further improve the compactness of the overall structure, in this embodiment, the outdoor air outlet 55 and the fresh air inlet 51 are located on the same side of the housing 5; the indoor air outlet 54 and the circulating air outlet 53 are located on the same side of the housing 5. Both the fresh air inlet 51 and the outdoor air outlet 55 are communicated with the outdoor environment. In application, a through-wall pipe can be directly externally connected at the air outlet or a connecting air duct can be installed at the air outlet and passed through to the outside. By arranging the fresh air inlet 51 and the outdoor air outlet 55 on the same side of the housing 5, only the area on the same side of the housing 5 needs to be taken over for piping, without occupying the areas on other sides of the housing 5, reducing the occupied space of the overall structure of the air treatment device.

[0100] Similarly, both the indoor air outlet 54 and the circulating air outlet 53 are communicated with the indoor environment. In application, an air duct communicated with different indoor areas can be installed at the air outlet or directly communicated with the indoor environment. By arranging the indoor air outlet 54 and the circulating air outlet 53 on the same side of the housing 5, only the area on the same side of the housing 5 is occupied for piping operations, without occupying the areas on other sides of the housing 5, reducing the occupied space of the overall structure of the air treatment device.

[0101] Please review Figures 3 to 5 , such as Figures 3 to 5As shown in the figure, in order to improve the heat utilization rate, in this embodiment, a second gas-gas heat exchanger 10 is provided in the housing 5. The exhaust air duct and the fresh air duct cross through the second gas-gas heat exchanger 10. When the fresh air passes through one side of the second gas-gas heat exchanger 10, it exchanges heat with the exhaust air passing through the second side of the second gas-gas heat exchanger 10 and then flows to the gas-liquid separation component.

[0102] In this embodiment, by providing the second gas-gas heat exchanger 10, the exhaust air duct and the fresh air duct are arranged in a cross manner. The fresh air passes through the first side of the second gas-gas heat exchanger 10, and the exhaust air passes through the second side of the second gas-gas heat exchanger 10. When the exhaust air and the fresh air flow through the second gas-gas heat exchanger 10 in a positive cross manner respectively, due to the temperature difference and the vapor partial pressure difference between the airflows on both sides of the air flow partition plate of the second gas-gas heat exchanger 10, a heat and mass transfer phenomenon occurs when the two airflows pass through the partition plate of the second gas-gas heat exchanger 10, causing a total heat exchange process, thereby realizing the recovery and utilization of the heat of the exhausted indoor air to reduce the temperature difference between the introduced fresh air and the indoor temperature and achieve an energy-saving effect.

[0103] Please review Figures 3 to 5 , as Figures 3 to 5 shown, the fresh air duct in the housing 5 is divided into a fresh air fan chamber 5 a , a first heat exchange chamber 5b, a second heat exchange chamber 5 c and a third heat exchange chamber 5d by a partition plate. The circulation duct is divided into a circulation fan chamber 5 e by a partition plate. The first heat exchange chamber 5b is located between the fresh air fan chamber 5 a and the second heat exchange chamber 5 c . The third heat exchange chamber 5d is arranged in parallel with the second heat exchange chamber 5 c . The fresh air fan 6 is arranged in the fresh air fan chamber 5 a . The fresh air fan chamber 5 a is communicated with the first heat exchange chamber 5b. The second gas-gas heat exchanger 10 is arranged in the first heat exchange chamber 5b. The first gas-gas heat exchanger 2 is arranged in the second heat exchange chamber 5 c . The refrigerant heat exchanger 1 is arranged in the third heat exchange chamber 5d. The circulation fan 7 is arranged in the circulation fan chamber 5 e . The circulation fan chamber 5 e is communicated or isolated from the fresh air fan chamber 5 a through a bypass valve 8. The exhaust air fan 9 is arranged in the exhaust air duct and is close to the outdoor exhaust air outlet 55. The exhaust air duct passes through the first heat exchange chamber 5b. For the convenience of description, the part where the fresh air starts to enter the second gas-gas heat exchanger 10 is called the air duct a , the part where the fresh air leaves the second gas-gas heat exchanger 10 is called the air duct b. The part of the air duct b close to the first gas-gas heat exchanger 2 and the refrigerant heat exchanger 1 is further divided into an air duct by a partition platec Japanese style e , air duct c Japanese style e The air duct is respectively located at the air inlet of the first gas channel and the air inlet of the second gas channel of the first gas-gas heat exchanger 2. c The first gas channel of the first gas-gas heat exchanger 2 is connected to the air duct e It is connected with the second gas channel of the first gas-gas heat exchanger 2 and the air port near the first section of the refrigerant heat exchanger 1. The fresh air duct near the air supply port 52 is divided into duct d and duct f by a partition. Duct d and duct f are respectively located at the air outlet of the first gas channel and the air outlet of the second gas channel of the first gas-gas heat exchanger 2, wherein duct d is connected with the first gas channel of the first gas-gas heat exchanger 2 and the refrigerant heat exchanger 1 at the same time, duct f is only connected with the second gas channel of the first gas-gas heat exchanger 2, and the part of the circulating air duct close to the first gas-gas heat exchanger 2 and the refrigerant heat exchanger 1 is called duct b1, and duct b1 is connected with duct b.

[0104] Please review Figure 4 and Figure 5 ,like Figure 4 and Figure 5 As shown, when the air handling device uses the first mode of the gas-liquid separation component to dehumidify the fresh air, the first air valve component 3 e The inlet of c The inlet of the air duct d is opened, the second air valve assembly 4 closes the outlet of the air duct d, and at the same time opens the outlet of the air duct f, and the fresh air enters the fresh air fan chamber 5 from the fresh air inlet 12 a , and then under the action of the fresh air fan 6, the fresh air fan cavity 5 a Air duct entering the first heat exchange chamber 5b a , and by the wind duct a The exhaust air flows to the first side of the second gas-gas heat exchanger 10, and the exhaust air enters the exhaust duct from the indoor exhaust port 54, and flows to the second side of the second gas-gas heat exchanger 10 from the exhaust duct. After the fresh air and the exhaust air are heat exchanged at the second gas-gas heat exchanger 10, the exhaust air is discharged from the outdoor exhaust port 55, and the fresh air enters the air duct b, and then enters the air duct b from the air duct b. c , and then by the wind duct c Entering the second heat exchange chamber 5 c , in the second heat exchange chamber 5 c The first gas channel of the first gas-gas heat exchanger 2 flows to the air duct d, and then passes through the refrigerant heat exchanger 1 from the air duct d to enter the air duct e , and then by the wind duct eThe second gas flow through the second gas channel of the first gas-gas heat exchanger 2 towards the air duct f, and finally flows from the air duct f to the air supply outlet 52, and is discharged from the air supply outlet 52. Since the fresh air entering the first gas channel of the first gas-gas heat exchanger 2 is the fresh air after heat exchange with the second gas-gas heat exchanger 10, and the air entering the second gas channel of the first gas-gas heat exchanger 2 is the fresh air cooled by the refrigerant heat exchanger 1, when the fresh air passes through the first gas channel of the first gas-gas heat exchanger 2, it is precooled by the fresh air passing through the second gas channel of the first gas-gas heat exchanger 2, and heat exchange occurs with the fresh air in the second gas channel of the first gas-gas heat exchanger 2, thereby increasing the temperature of the air on the second side of the first gas-gas heat exchanger 2. Therefore, when the fresh air passes through the second gas channel of the first gas-gas heat exchanger 2, it is also in the process of being preheated by the fresh air in the first gas channel of the first gas-gas heat exchanger 2. In this way, after the fresh air flows from the second gas channel of the first gas-gas heat exchanger 2 to the air duct f, its temperature is slightly higher than that of the fresh air cooled by the refrigerant heat exchanger 1. Blowing such air directly onto the human body will make people feel more comfortable.

[0105] For example, at an atmospheric pressure of 100 kP a , the fresh air volume of the air handling unit is 200 m 3 / h, the supply air volume is 200 m 3 / h, the static pressure at the fresh air inlet 51 is 50 kP a , the static pressure at the air supply outlet 52 is 50 kP a , when the exhaust air enters the indoor exhaust air outlet 54: the dry bulb temperature is 23 °C, the wet bulb temperature is 17.7 °C, the relative humidity is 62% RH, and the moisture content is 11 / k g , the outdoor fresh air enters the air duct a from the fresh air fan chamber 5 a : the dry bulb temperature is 35 °C, the wet bulb temperature is 28 °C, the relative humidity is 60.2% RH, and the moisture content is 22 / k g , the fresh air flows from the air duct a towards the first side of the second gas-gas heat exchanger 10, and the exhaust air flows from the exhaust air duct towards the second side of the second gas-gas heat exchanger 10. At the second gas-gas heat exchanger 10, heat exchange occurs between the exhaust air and the fresh air. When the exhaust air passes through the second gas-gas heat exchanger 10 and is discharged to the outdoor exhaust air outlet 55: the dry bulb temperature is 30.1 °C, the wet bulb temperature is 22.7 °C, the relative humidity is 58% RH, and the moisture content is 15.87 / k g , when the fresh air exits the second gas-gas heat exchanger 10 and enters the air duct b: the dry bulb temperature is 26.2 °C, the wet bulb temperature is 22.6 °C, the relative humidity is 75.4% RH, and the moisture content is 16.3 / k g, fresh air enters the air duct from the air duct b c When it reaches: the dry bulb temperature is 26.2 °C, the wet bulb temperature is 22.6 °C, the relative humidity is 75.4% RH, and the water content is 16.3 / k g , the fresh air passes through the air duct c and enters the second heat exchange chamber 5 c , in the second heat exchange chamber 5 c it flows through the first gas-gas heat exchanger 2's first gas channel towards the air duct d. When the fresh air enters the air duct d: the dry bulb temperature is 17.9 °C, the wet bulb temperature is 17.9 °C, the relative humidity is 100% RH, and the water content is 12.8559 g / k g , then the fresh air passes through the refrigerant heat exchanger 1 from the air duct d and enters the air duct e , when the fresh air reaches the air duct e : the dry bulb temperature is 10 °C, the wet bulb temperature is 10 °C, the relative humidity is 100% RH, and the water content is 7.6544 g / k g , the fresh air passes through the second gas channel of the first gas-gas heat exchanger 2 from the air duct e towards the air duct f. When the fresh air enters the air duct f: the dry bulb temperature is 19.2 °C, the wet bulb temperature is 13.5 °C, the relative humidity is 54.8% RH, and the water content is 7.6544 g / kg.

At the same time, the exhaust air enters the exhaust air duct from the indoor exhaust air outlet 54 and flows through the exhaust air duct to the second side of the second gas-gas heat exchanger 10.

The fresh air passing through the first gas passage of the first gas-gas heat exchanger 2 and the fresh air dehumidified and cooled by the refrigerant heat exchanger 1 are mixed in the air duct d. The mixed fresh air is further mixed with the air passing through the second side of the first gas-gas heat exchanger 2 at the air supply outlet 52.

[0109] Please review Figure 4 and Figure 5 , such as Figure 4 and Figure 5 shown, when the air treatment device dehumidifies the air in the second mode using the gas-liquid separation component, when the first gas valve component 3 opens the air inlet of the first gas passage, the air inlets of the second gas passage and the air port near the first section of the refrigerant heat exchanger 1 are opened simultaneously, and the second gas valve component 4 opens all the air outlets of the first gas passage, the second gas passage of the first gas-gas heat exchanger 2 and the air port near the second section of the refrigerant heat exchanger 1, the outlets of the air ducts f and d are opened simultaneously. Outdoor fresh air enters the fresh air fan chamber 5 from the fresh air inlet 51 a , and then enters the air duct of the first heat exchange chamber 5b under the action of the fresh air fan 6 a , and flows from the air duct a to the first side of the second gas-gas heat exchanger 10. At the same time, the exhaust air enters the exhaust air duct from the indoor exhaust air outlet 54 and flows to the second side of the second gas-gas heat exchanger 10. After the fresh air and the exhaust air exchange heat at the second gas-gas heat exchanger 10, the exhaust air is discharged from the outdoor exhaust air outlet 55, and the fresh air enters the air duct b. A part of the fresh air entering the air duct b can enter the air duct a from the air duct b, and a part of the fresh air entering the air duct e enters the air duct e . A part of the fresh air entering the air duct e passes through the refrigerant heat exchanger 1 to reach the air duct d, and another part of the fresh air entering the air duct e enters the second gas passage of the first gas-gas heat exchanger 2, and then enters the air duct f from the second gas passage of the first gas-gas heat exchanger 2. The fresh air passing through the second side of the first gas-gas heat exchanger 2 is mixed with the fresh air dehumidified and cooled by the refrigerant heat exchanger 1 at the air supply outlet 52.

[0110] Please review Figure 4 and Figure 5 , such as Figure 4 and Figure 5As shown, when the air handling device uses the third mode of the gas-liquid separation component to dehumidify the fresh air, the first air valve component 3 opens the air port near the first section of the refrigerant heat exchanger 1 at the same time, and the second air valve component 4 opens the air port near the second section of the refrigerant heat exchanger 1. c The inlet is closed, at this time, the air duct e The inlet of is in an open state, and the outdoor fresh air enters the fresh air fan cavity 5 through the fresh air inlet 51. a , and then enters the air duct of the first heating chamber 1b under the action of the fresh air fan 6 a , and then under the action of the fresh air fan 6, the fresh air fan cavity 5 a Air duct entering the first heat exchange chamber 5b a , and by the wind duct a The exhaust air flows to the first side of the second gas-gas heat exchanger 10, and the exhaust air enters the exhaust duct from the indoor exhaust port 54, and flows to the second side of the second gas-gas heat exchanger 10 from the exhaust duct. After the fresh air and the exhaust air are heat exchanged at the second gas-gas heat exchanger 10, the exhaust air is discharged from the outdoor exhaust port 55, and the fresh air enters the duct b, and then enters the duct b from the duct b. e , by the wind duct e It flows to the refrigerant heat exchanger 1, is cooled and dehumidified in the refrigerant heat exchanger 1, and then flows to the air duct d, and then flows from the air duct d to the air supply port 52, and finally is discharged into the room from the air supply port 52.

[0111] After a rainy day in summer or in plum rain weather, the outdoor temperature is high and the humidity content is high, and the indoor temperature and humidity content are also high. At this time, the third mode needs to be used for dehumidification, because in the third dehumidification mode, the fresh air is dehumidified and cooled before being directly introduced into the room. In the third mode, the dehumidification method of the fresh air gas-liquid separation component is to first pass the fresh air through the second gas-gas heat exchanger 10. At the second gas-gas heat exchanger 10, the fresh air can be heated by the exhaust air passing through the second side of the second gas-gas heat exchanger 10, or it can be cooled by the exhaust air on the other side of the second gas-gas heat exchanger 10. The cooling or heating depends on the temperature of the fresh air and the exhaust air. When the dehumidification operation is performed in summer, the fresh air obtains cooling capacity from the exhaust air to reduce the temperature, and is dried by the exhaust air at the same time to reduce the moisture content of the fresh air. In this way, through the full heat exchange process of the second gas-gas heat exchanger 10, the exhaust air and the incoming fresh air are used to exchange heat and moisture to recover energy, so that the fresh air recovers energy from the exhaust air, and the fresh air is pre-cooled and preliminarily dehumidified. The air that undergoes heat and moisture exchange at the second gas-gas heat exchanger 10 enters the air duct through the air duct b. e Flowing to duct d, e In the process of entering the air duct d, the air that exchanges heat with the second gas-to-gas heat exchanger 10 is cooled and dehumidified by the refrigerant heat exchanger 1, and then flows from the air duct d to the air supply port 52, and finally is discharged into the room from the air supply port 52, which can dehumidify and cool the fresh air at the same time.

[0112] Please review Figure 4 and Figure 5 as Figure 4 and Figure 5 shown, when the air handling unit dehumidifies fresh air in the fourth mode of the gas-liquid separation component, the first gas valve assembly 3 opens the air inlet of the second gas channel of the first gas-gas heat exchanger 2, the second gas valve assembly 4 opens the air outlet of the second gas channel of the first gas-gas heat exchanger 2, the outlet of the air duct d is closed, the outlet of the air duct f is opened, and the outdoor fresh air enters the fresh air fan chamber 5 from the fresh air inlet 51 a , and then enters the air duct of the first heating chamber 1b under the action of the fresh air fan 6 a , and then enters the air duct of the first heat exchange chamber 5b from the fresh air fan chamber 5 under the action of the fresh air fan 6 a , and flows to the first side of the second gas-gas heat exchanger 10 through the air duct a , and at the same time, the exhaust air enters the exhaust air duct from the indoor air outlet 54 and flows to the second side of the second gas-gas heat exchanger 10 through the exhaust air duct. After the fresh air and the exhaust air exchange heat at the second gas-gas heat exchanger 10, the exhaust air is discharged from the outdoor air outlet 55, and the fresh air enters the air duct b. The fresh air entering the air duct b enters the air duct a , and then enters the second gas channel of the first gas-gas heat exchanger 2 through the air duct e , and then enters the second gas channel of the first gas-gas heat exchanger 2 from the air duct e , and then flows along the second gas channel of the first gas-gas heat exchanger 2 to the air duct f, and finally is discharged from the air duct f. When the fresh air passes through the second gas channel of the first gas-gas heat exchanger 2, since the refrigerant heat exchanger 1 is arranged in parallel with the first gas-gas heat exchanger 2 and the refrigerant heat exchanger 1 is close to the second gas channel of the first gas-gas heat exchanger 2, the refrigerant heat exchanger 1 can cool and dehumidify the air on the second side of the first gas-gas heat exchanger 2

[0113] In this embodiment, the second gas-gas heat exchanger 10 adopts a total heat exchanger. The fresh air passing through the first side of the second gas-gas heat exchanger 10 and the exhaust air passing through the second side of the second gas-gas heat exchanger 10 can exchange humidity and temperature. When operating the dehumidification operation in the humid weather or rainy season in summer, the temperature and humidity of the outdoor air are higher than those of the indoor air. When the fresh air and the exhaust air pass through the first side and the second side of the second gas-gas heat exchanger 10 respectively, the fresh air obtains cold energy from the exhaust air, the temperature is reduced, and at the same time, it is dried by the exhaust air, so that the moisture content of the fresh air is reduced; when operating in winter, the indoor air temperature is higher than the outdoor air temperature. When the fresh air and the exhaust air pass through the first side and the second side of the second gas-gas heat exchanger 10 respectively, the fresh air obtains heat from the exhaust air, the temperature is increased, and at the same time, the moisture content is increased, so that the fresh air recovers energy from the exhaust air

[0114] The above four modes of the air-liquid separation component are all introduced with all the air entering the air-liquid separation component being fresh air, and the fresh air inlet mode being Mode 1. When the air inlet of the air-liquid separation component is fresh air and the fresh air inlet mode is Mode 2, the fresh air enters the air duct b1 from the circulation air duct, and then enters the air duct b from the air duct b1. At the air duct b, the air-liquid separation component can also have four dehumidification modes. The flow direction of the fresh air at the air duct b is the same as the above-mentioned mode when the fresh air flows to the air duct b. To make the text concise, it will not be repeated here.

[0115] When the fresh air inlet mode of the air-liquid separation component is Mode 3, part of the fresh air is introduced by the fresh air fan 6 to the first side of the second gas-gas heat exchanger 10 to exchange heat with the exhaust air and then flows to the air duct b. Part of the fresh air enters the air duct b1 from the circulation air duct under the action of the circulation fan 7, and then the fresh air entering the air duct b from the air duct b1 can be mixed with the fresh air flowing from the second gas-gas heat exchanger 10 to the air duct b. Then the mixed fresh air starts to enter the air-liquid separation component at the air duct b, and the air-liquid separation component can dehumidify by any one of the four dehumidification modes as needed.

[0116] When the air handling unit only dehumidifies the recirculated air, the recirculated air enters the circulation air duct under the action of the circulation fan 7, then flows from the circulation air duct to the air duct b1, and then enters the air duct b from b1. When entering the air-liquid separation component from the air duct b, the air-liquid separation component can dehumidify by any one of the four dehumidification modes as needed. The dehumidification principle is the same and will not be repeated here.

[0117] The following takes the air-liquid separation component dehumidifying the recirculated air in the second mode as an example to describe the dehumidification process and effect of the air-liquid separation component on the recirculated air:

When the circulating air enters the air duct d: the dry bulb temperature is 16.3 °C, the wet bulb temperature is 16.3 °C, the relative humidity is 100% RH, and the water content is 11.5941 g / k g , and then the circulating air passes through the refrigerant heat exchanger 1 from the air duct d and enters the air duct e . When the circulating air enters the air duct e : the dry bulb temperature is 10 °C, the wet bulb temperature is 10 °C, the relative humidity is 100% RH, and the water content is 7.6544 g / k g , and from the air duct e it flows through the second gas passage of the first gas-gas heat exchanger 2 towards the air duct f. When the circulating air enters the air duct f: the dry bulb temperature is 16.9 °C, the wet bulb temperature is 12.8 °C, the relative humidity is 63.5% RH, and the water content is 7.6544 g / k g .

[0119] In the relatively humid weather in summer, the moisture content and temperature of the indoor air are relatively high, and the atmospheric pressure is 100 kP a . The circulating air volume of the air handling unit is 200 m 3 / h, the supply air volume is 200 m 3 / h, the static pressure of the circulating air outlet 53 is 50 kP a , and the static pressure of the supply air outlet 52 is 50 kP a . When the circulating air enters the air duct c : the dry bulb temperature is 35 °C, the wet bulb temperature is 33.2 °C, the relative humidity is 90% RH, and the water content is 32.7092 g / k g . The circulating air passes through the air duct c and enters the second heat exchange chamber 5 c . Inside the second heat exchange chamber 5 c the first gas flows through the first gas passage of the first gas-gas heat exchanger 2 towards the air duct d. When the circulating air enters the air duct d: the dry bulb temperature is 22 °C, the wet bulb temperature is 22 °C, the relative humidity is 100% RH, and the water content is 16.6715 g / k g , and then the circulating air passes through the refrigerant heat exchanger 1 from the air duct d and enters the air duct e . When the circulating air enters the air duct e : the dry bulb temperature is 10 °C, the wet bulb temperature is 10 °C, the relative humidity is 100% RH, and the water content is 7.6544 g / k g , and from the air duct eThe second gas passage of the first gas-gas heat exchanger 2 flows towards the air duct f. When the recirculated air enters the air duct f: the dry bulb temperature is 23°C, the wet bulb temperature is 14.6°C, the relative humidity is 43.1%RH, and the water content is 7.6544 g / k g .

[0121] The present invention also provides another air treatment device. The air treatment device is provided with the gas-liquid separation component of Embodiment 1, and the air treatment device can dehumidify the indoor recirculated air by using any one of the four gas-liquid separation modes of the gas-liquid separation component.

[0122] Please refer to Figures 6 to 8 , as Figures 6 to 8 shown, the air treatment device includes a housing 5, a circulation fan 7 and a gas-liquid separation component. A circulation air inlet 53, an air supply outlet 52 and a circulation air duct connecting the circulation air inlet 53 and the air supply outlet 52 are provided in the housing 5. The circulation fan 7 is arranged in the circulation air duct, and the gas-liquid separation component is arranged in the circulation air duct. The first gas-gas heat exchanger 2 and the refrigerant heat exchanger 1 of the gas-liquid separation component are arranged in parallel in the circulation air duct and are located between the circulation fan 7 and the air supply outlet 52.

[0123] Please review Figures 6 to 8 , as Figures 6 to 8 shown, the circulation air duct in the housing 5 is divided into a circulation fan chamber 5 e , a second heat exchange chamber 5 c and a third heat exchange chamber 5d by a partition. The circulation fan chamber 5 e is arranged close to the circulation air inlet 53. The third heat exchange chamber 5d is arranged in parallel with the second heat exchange chamber 5 c . The circulation fan 7 is arranged in the circulation fan chamber 5 e . An air duct b1 is provided at the outlet position of the circulation fan chamber 5 e . An air duct c is provided at the inlet of the second heat exchange chamber 5 c . An air duct e is provided at the inlet of the third heat exchange chamber 5d. The part of the second heat exchange chamber 5 c close to the air supply outlet 52 is the air duct f, and the part of the third heat exchange chamber 5d close to the air supply outlet 52 is the air duct d. The air duct d is located above the air duct f. The first gas-gas heat exchanger 2 is arranged in the second heat exchange chamber 5 c . The air duct c and the air duct d are connected to the first gas passage of the first gas-gas heat exchanger 2. The air duct e and the air duct f are connected to the second gas passage of the first gas-gas heat exchanger 2. The refrigerant heat exchanger 1 is arranged in the third heat exchange chamber 5d. The air duct e and the air duct d are connected to the refrigerant heat exchanger 1.

[0124] Please review Figure 7 and Figure 8 as Figure 7 and Figure 8 shown, when the air handling device of this embodiment uses the first mode of the gas-liquid separation component to dehumidify the circulating air, the first gas valve assembly 3 opens the air inlet of the first gas channel of the first gas-gas heat exchanger 2, and at the same time closes the air inlet of the second gas channel of the first gas-gas heat exchanger 2 and the air port near the first section of the refrigerant heat exchanger 1. The second gas valve assembly 4 closes the air outlet of the first gas channel of the first gas-gas heat exchanger 2 and the air port near the second section of the refrigerant heat exchanger 1.

When the air passes through the second gas channel of the first gas-gas heat exchanger 2, it is also in the process of being preheated by the air in the first gas channel of the first gas-gas heat exchanger 2. In this way, after the air flows from the second gas channel of the first gas-gas heat exchanger 2 to the air duct f, the temperature is slightly higher than the air cooled by the refrigerant heat exchanger 1. Such air directly blown on the human body will make the human body more comfortable.

A part of the air entering the air duct b1 can enter the air duct e , and then from the air duct e passes through the refrigerant heat exchanger 1 to reach the air duct d. Another part of the air entering the air duct b can pass through the air duct c to enter the first gas passage of the first gas-gas heat exchanger 2, and then enters the air duct d from the first gas passage of the first gas-gas heat exchanger 2.

A part of the air entering the air duct b1 can enter the air duct e , and a part of the air entering the air duct e passes through the refrigerant heat exchanger 1 to reach the air duct d from the air duct e and enters the air ducte Another part of the gas enters the second gas passage of the first gas-gas heat exchanger 2, and then enters the air duct f from the second gas passage of the first gas-gas heat exchanger 2. Another part of the air entering the air duct b1 can pass through the air duct c enters the first gas passage of the first gas-gas heat exchanger 2, and then enters the air duct d from the first gas passage of the first gas-gas heat exchanger 2. The air passing through the first side of the first gas-gas heat exchanger 2 and the air dehumidified and cooled by the refrigerant heat exchanger 1 are mixed in the air duct d. The mixed air is further mixed with the air passing through the second side of the first gas-gas heat exchanger 2 at the air supply outlet 52.

[0129] Please review Figure 7 and Figure 8 , such as Figure 7 and Figure 8 shown, when the air treatment device of this embodiment uses the second mode of the gas-liquid separation component to dehumidify the circulating air, when the first gas valve component 3 opens the air inlet of the first gas passage, the air inlets of the second gas passage and the air port near the first section of the refrigerant heat exchanger 1 are opened simultaneously, and the second gas valve component 4 opens all the air outlets of the first gas passage, the second gas passage of the first gas-gas heat exchanger 2 and the air port near the second section of the refrigerant heat exchanger 1. When the first gas valve component 5 is in the closed state and the second gas valve component 6 is in the semi-open state, the inlet of the air duct c is closed, and the outlets of the air ducts f and d are opened simultaneously. The air enters the circulating fan chamber 5 from the circulating air inlet 53 e , and then enters the air duct b1 from the circulating fan chamber 5 under the action of the circulating fan 7 e . A part of the air entering the air duct b1 can enter the air duct e from the air duct b1, and enter the air duct e . A part of the air entering the air duct e passes through the refrigerant heat exchanger 1 to reach the air duct d. Another part of the gas entering the air duct e enters the second gas passage of the first gas-gas heat exchanger 2, and then enters the air duct f from the second gas passage of the first gas-gas heat exchanger 2. The air passing through the second side of the first gas-gas heat exchanger 2 is mixed with the air dehumidified and cooled by the refrigerant heat exchanger 1 at the air supply outlet 52.

[0130] Please review Figure 7 and Figure 8 , such as Figure 7 and Figure 8As shown, when the air handling device of this embodiment uses the third mode of the gas-liquid separation component to dehumidify the circulating air, the first gas valve component 3 opens the air ports near the first section of the refrigerant heat exchanger 1 simultaneously, and the second gas valve component 4 opens the air ports near the second section of the refrigerant heat exchanger 1. The air enters the circulating fan chamber 5 from the circulating air port 51 e , and then enters the air duct b1 under the action of the circulating fan 7, and then enters the air duct from the air duct b1 e , from the air duct e flows to the refrigerant heat exchanger 1, is cooled and dehumidified at the refrigerant heat exchanger 1 and then flows to the air duct d, and then flows from the air duct d to the air supply port 52, and finally is discharged into the room from the air supply port 52. In the process of entering the air duct d from the air duct e , the air is cooled and dehumidified by the refrigerant heat exchanger 1, then flows from the air duct d to the air supply port 52, and finally is discharged into the room from the air supply port 52. It can dehumidify and cool the air at the same time. The second mode is suitable for rainy seasons in summer. At this time, the humidity of the outdoor air is greater than that of the indoor air, and the indoor air has high humidity and high temperature. After the gas-liquid separation component dehumidifies the indoor air, it can not only reduce the humidity of the indoor air, but also cool the indoor air

[0131] Please review Figure 7 and Figure 8 , as Figure 7 and Figure 8 shown, when the air handling device of this embodiment uses the fourth mode of the gas-liquid separation component to dehumidify the circulating air, the first gas valve component 3 opens the air inlet of the second gas channel of the first gas-gas heat exchanger 2, and the second gas valve component 4 opens the air outlet of the second gas channel of the first gas-gas heat exchanger 2. The outlet of the air duct f is opened, and the air enters the circulating fan chamber 5 from the air inlet e , and then enters the air duct b1 from the circulating fan chamber 5 under the action of the circulating fan 7 e , the air entering the air duct b1 enters the air duct e , and then from the air duct eEnter the second gas passage of the first gas-gas heat exchanger 2, then flow along the second gas passage of the first gas-gas heat exchanger 2 towards the air duct f, and finally be discharged from the air duct f. When the air passes through the second gas passage of the first gas-gas heat exchanger 2, since the refrigerant heat exchanger 1 is arranged in parallel with the first gas-gas heat exchanger 2 and the refrigerant heat exchanger 1 is close to the second gas passage of the first gas-gas heat exchanger 2, the refrigerant heat exchanger 1 can cool and dehumidify the air on the second side of the first gas-gas heat exchanger 2. The static dehumidification mode is applicable to the situation where the indoor air temperature is appropriate but the humidity is slightly high. In the static dehumidification mode, since the second gas passage of the first gas-gas heat exchanger 2 is adjacent to the refrigerant heat exchanger 1, when the air passes through the second gas passage of the first gas-gas heat exchanger 2, the low-temperature liquid refrigerant in the refrigerant heat exchanger 1 can still exchange heat with the air passing through the second gas passage of the first gas-gas heat exchanger 2, cooling the air in the second gas passage of the first gas-gas heat exchanger 2 to condense out moisture, and then the air recovers the condensation heat of the system to make up for the heat lost when the air is cooled and dehumidified, so that the temperature of the air remains unchanged when it is discharged and the humidity decreases.

The dehumidifier in this embodiment can use the gas-liquid separation component of Embodiment 1 to perform dehumidification operations in any one of the four modes on the fresh air.

[0138] Please refer to Figures 8 to 10 , as Figures 8 to 10 shown, the dehumidifier includes a housing 5, a fresh air fan 6 and a gas-liquid separation component. A fresh air inlet 51, an air outlet 52 and a fresh air passage are provided inside the housing 5. The fresh air duct connects the fresh air inlet 51 and the air outlet 52. The gas-liquid separation component is arranged downstream of the fresh air duct; the fresh air fan 6 is arranged in the fresh air duct. The fresh air fan 6 is used to drive the outdoor fresh air to enter the fresh air duct from the fresh air inlet 51 and flow to the gas-liquid separation component for dehumidification. The air after being dehumidified by the gas-liquid separation component is the processed air, and the processed air is discharged from the air outlet 52.

[0139] Please review Figure 10 , as Figure 10 , the fresh air duct inside the housing 5 is divided into a fresh air fan chamber 5 a , a second heat exchange chamber 5 c and a third heat exchange chamber 5d by a partition. The fresh air fan chamber 5 a is arranged close to the fresh air inlet 51. The third heat exchange chamber 5d is arranged in parallel with the second heat exchange chamber 5 c . The fresh air fan 6 is arranged in the fresh air fan chamber 5 a . A duct b is provided at the position of the air outlet of the fresh air fan chamber 5 a .

The air duct d is located above the air duct f. The first gas-gas heat exchanger 2 is arranged in the second heat exchange chamber 5 c , the air duct c and the first gas passage of the first gas-gas heat exchanger 2 that is communicated with the air duct d, the air duct e and the second gas passage of the first gas-gas heat exchanger 2 that is communicated with the air duct f. The refrigerant heat exchanger 1 is arranged in the third heat exchange chamber 5d. The air duct e is communicated with the refrigerant heat exchanger 1. The liquid refrigerant in the refrigerant heat exchanger 1 exchanges heat with the air in the air duct. The first gas-gas heat exchanger 2 and the refrigerant heat exchanger 1 are arranged side by side.

[0140] Please review Figure 8 , such as Figure 8 shown. When the dehumidifier dehumidifies the fresh air in the first mode of the gas-liquid separation component, the first air valve component 3 opens the air inlet of the first gas passage of the first gas-gas heat exchanger 2, and at the same time closes the air inlet of the second gas passage of the first gas-gas heat exchanger 2 and the air port near the first section of the refrigerant heat exchanger 1. The second air valve component 4 closes the air outlet of the first gas passage of the first gas-gas heat exchanger 2 and the air port near the second section of the refrigerant heat exchanger 1. The air enters the fresh air fan chamber 5 from the fresh air inlet 51 a , and enters the air duct b under the action of the fresh air fan 6, and then enters the air duct from the air duct b c , and then from the air duct c enters the second heat exchange chamber 5 c , in the second heat exchange chamber 5 c flows through the first side of the first gas-gas heat exchanger 2 to the air duct d, and then enters the air duct from the air duct d through the refrigerant heat exchanger 1 e , and then from the air duct e flows through the second gas passage of the first gas-gas heat exchanger 2 to the air duct f, and finally flows from the air duct f to the air supply outlet 52 and is discharged from the air supply outlet 52. When the air passes through the second gas passage of the first gas-gas heat exchanger 2, it is also in the process of being preheated by the air in the first gas passage of the first gas-gas heat exchanger 2. In this way, after the air flows from the second gas passage of the first gas-gas heat exchanger 2 to the air duct f, the temperature is slightly higher than the air cooled by the refrigerant heat exchanger 1. Such air directly blown to the human body will make the human body more comfortable.

[0141] For example, at an atmospheric pressure of 100 kP a , the fresh air volume of the air treatment device is 200 m 3 / h, and the air supply volume is 200 m3 / h, the static pressure at the fresh air inlet 51 is 50 kP a , the static pressure at the air supply outlet 52 is 50 kP a , the fresh air enters the air duct c When it reaches: the dry bulb temperature is 26.2 °C, the wet bulb temperature is 22.6 °C, the relative humidity is 75.4% RH, and the water content is 16.3 / k g , the fresh air passes through the air duct c and enters the second heat exchange chamber 5 c , in the second heat exchange chamber 5 c it flows from the first side of the first gas-gas heat exchanger 2 to the air duct d. When the fresh air enters the air duct d: the dry bulb temperature is 17.9 °C, the wet bulb temperature is 17.9 °C, the relative humidity is 100% RH, and the water content is 12.8559 g / k g , then the fresh air passes through the refrigerant heat exchanger 1 from the air duct d and enters the air duct e , when the fresh air enters the air duct e : the dry bulb temperature is 10 °C, the wet bulb temperature is 10 °C, the relative humidity is 100% RH, and the water content is 7.6544 g / k g , the fresh air passes through the second gas passage of the first gas-gas heat exchanger 2 from the air duct e to the air duct f. When the fresh air enters the air duct f: the dry bulb temperature is 19.2 °C, the wet bulb temperature is 13.5 °C, the relative humidity is 54.8% RH, and the water content is 7.6544 g / k g .

[0142] For example, at an atmospheric pressure of 100 kP a , the fresh air volume of the air handling unit is 200 m 3 / h, the air supply volume is 200 m 3 / h, the static pressure at the fresh air inlet 51 is 50 kP a , the static pressure at the air supply outlet 52 is 50 kP a , when the fresh air enters the air duct c : the dry bulb temperature is 21.25 °C, the wet bulb temperature is 18.1 °C, the relative humidity is 75.4% RH, and the water content is 12 g / k g , the fresh air passes through the air duct c and enters the second heat exchange chamber 5 c , in the second heat exchange chamber 5 c it flows from the first side of the first gas-gas heat exchanger 2 to the air duct d. When the fresh air enters the air duct d: the dry bulb temperature is 15.625 °C, the wet bulb temperature is 15.6 °C, the relative humidity is 100% RH, and the water content is 11.096g / k g After that, the fresh air enters the air duct through the refrigerant heat exchanger 1 from the air duct d e The fresh air enters the air duct e When it reaches: the dry bulb temperature is 10°C, the wet bulb temperature is 10°C, the relative humidity is 100%RH, and the water content is 7.6544 g / k g From the air duct e flows through the second gas passage of the first gas-gas heat exchanger 2 to the air duct f. When the fresh air enters the air duct f: the dry bulb temperature is 15.2°C, the wet bulb temperature is 12.6°C, the relative humidity is 71%RH, and the water content is 7.6544 g / k g .

[0143] Please review Figure 8 , such as Figure 8 shown, when the dehumidifier of this embodiment uses the second mode of the gas-liquid separation component to dehumidify the fresh air, when the first gas valve component 3 opens the air inlet of the first gas passage, the air inlets of the second gas passage and the air port near the first section of the refrigerant heat exchanger 1 are opened at the same time, and the second gas valve component 4 opens the air outlet of the first gas passage of the first gas-gas heat exchanger 2 and the air port near the second section of the refrigerant heat exchanger 1, the air enters the fresh air fan chamber 5 from the fresh air inlet 51 a , and then enters the air duct b under the action of the fresh air fan 6. A part of the air entering the air duct b can enter the air duct e , and then from the air duct e reaches the air duct d through the refrigerant heat exchanger 1. Another part of the air entering the air duct b can enter the first gas passage of the first gas-gas heat exchanger 2 through the air duct c , and then enters the air duct d from the first gas passage of the first gas-gas heat exchanger 2. Since the air duct f is in a closed state, the air passing through the first gas passage of the first gas-gas heat exchanger 2 is mixed with the air that has been cooled and dehumidified by the refrigerant heat exchanger 1 at the air duct d. The mixed air enters the air duct d and flows to the air supply port 52, and finally is discharged from the air supply port 52

[0144] Please review Figure 8 , such as Figure 8 shown, when the dehumidifier of this embodiment uses the second mode of the gas-liquid separation component to dehumidify the fresh air, when the first gas valve component 3 opens the air inlets of the second gas passage and the air port near the first section of the refrigerant heat exchanger 1 at the same time, and the second gas valve component 4 opens the air outlet of the second gas passage of the first gas-gas heat exchanger 2 and the air port near the second section of the refrigerant heat exchanger 1, the air enters the fresh air fan chamber 5 from the fresh air inlet 51 a, and then enters the air duct b under the action of the fresh air fan 6. Part of the air entering the air duct b can enter the air duct from the air duct b e , enter the air duct e . Part of the air entering e reaches the air duct d through the refrigerant heat exchanger 1. The other part of the gas entering the air duct e enters the second gas channel of the first gas-gas heat exchanger 2, and then enters the air duct f from the second gas channel of the first gas-gas heat exchanger 2. The other part of the air entering the air duct b can pass through the air duct c and enter the first gas channel of the first gas-gas heat exchanger 2, and then enter the air duct d from the first gas channel of the first gas-gas heat exchanger 2. The air passing through the first side of the first gas-gas heat exchanger 2 and the air dehumidified and cooled by the refrigerant heat exchanger 1 are mixed in the air duct d, and the mixed air is further mixed with the air passing through the second side of the first gas-gas heat exchanger 2 at the air supply port 52.

[0145] Please review Figure 8 , such as Figure 8 shown. When the dehumidifier uses the second mode of the gas-liquid separation component to dehumidify the fresh air, when the first gas valve component 3 opens the air inlet of the first gas channel, the air inlets of the second gas channel and the air port near the first section of the refrigerant heat exchanger 1 are opened simultaneously, and the second gas valve component 4 opens all the air outlets of the first gas channel, the second gas channel of the first gas-gas heat exchanger 2 and the air port near the second section of the refrigerant heat exchanger 1, the air enters the fresh air fan chamber 5 from the fresh air inlet 51 a , and then enters the air duct b from the fresh air fan chamber 5 under the action of the fresh air fan 6 a . Part of the air entering the air duct b can enter the air duct from the air duct b e , enter the air duct e . Part of the air entering e reaches the air duct d through the refrigerant heat exchanger 1. The other part of the gas entering the air duct e enters the second gas channel of the first gas-gas heat exchanger 2, and then enters the air duct f from the second gas channel of the first gas-gas heat exchanger 2. The air passing through the second side of the first gas-gas heat exchanger 2 is mixed with the air dehumidified and cooled by the refrigerant heat exchanger 1 at the air supply port 52.

[0146] Please review Figure 8 , such as Figure 8 shown. When the dehumidifier uses the third mode of the gas-liquid separation component to dehumidify the fresh air, the first gas valve component 3 opens the air port near the first section of the refrigerant heat exchanger 1 simultaneously, and the second gas valve component 4 opens the air port near the second section of the refrigerant heat exchanger 1. The air enters the fresh air fan chamber 5 from the fresh air inlet 51 a, and then enter the air duct b under the action of the fresh air fan 6, and then enter the air duct from the air duct b e , from the air duct e flows to the refrigerant heat exchanger 1, is cooled and dehumidified at the refrigerant heat exchanger 1, then flows to the air duct d, and then flows from the air duct d to the air supply port 52, and finally is discharged into the room from the air supply port 52. When entering the air duct d from the air duct e , the air is cooled and dehumidified by the refrigerant heat exchanger 1, then flows from the air duct d to the air supply port 52, and finally is discharged into the room from the air supply port 52, which can dehumidify and cool the air at the same time.

[0147] Please review Figure 8 , such as Figure 8 shown, when the dehumidifier dehumidifies the fresh air in the fourth mode of the gas-liquid separation component, the first gas valve component 3 opens the air inlet of the second gas channel of the first gas-gas heat exchanger 2, and the second gas valve component 4 opens the air outlet of the second gas channel of the first gas-gas heat exchanger 2. The air enters the fresh air fan chamber 5 from the air inlet a , and then enters the air duct b from the fresh air fan chamber 5 under the action of the fresh air fan 6 a , the air entering the air duct b enters the air duct e , and then from the air duct e enters the second gas channel of the first gas-gas heat exchanger 2, and then flows along the second gas channel of the first gas-gas heat exchanger 2 to the air duct f, and finally is discharged from the air duct f. When the air passes through the second gas channel of the first gas-gas heat exchanger 2, since the refrigerant heat exchanger 1 and the first gas-gas heat exchanger 2 are arranged in parallel, and the refrigerant heat exchanger 1 is close to the second gas channel of the first gas-gas heat exchanger 2, the refrigerant heat exchanger 1 can cool and dehumidify the air on the second side of the first gas-gas heat exchanger 2, and make the air after dehumidification on the second side of the first gas-gas heat exchanger 2 absorb the condensation heat of the system to increase the temperature, achieving a static dehumidification process of dehumidifying without cooling. The static dehumidification mode is suitable for the situation where the indoor air temperature is appropriate but the humidity is slightly high. In the static dehumidification mode, since the second gas channel of the first gas-gas heat exchanger 2 is adjacent to the refrigerant heat exchanger 1, when the air passes through the second gas channel of the first gas-gas heat exchanger 2, the low-temperature liquid refrigerant in the refrigerant heat exchanger 1 can still exchange heat with the air passing through the second gas channel of the first gas-gas heat exchanger 2, so that the air in the second gas channel of the first gas-gas heat exchanger 2 is cooled and condensed to produce moisture, and then the air recovers the condensation heat of the system to make up for the heat lost when the air is cooled and dehumidified, so that the temperature of the air remains unchanged when it is discharged and the humidity is reduced.

[0148] The dehumidifier in this embodiment is a vertical dehumidifier. The first gas-gas heat exchanger 2 is vertically arranged in the air duct, and air passes through the first gas channel and / or the second side of the first gas-gas heat exchanger 2. The refrigerant heat exchanger 1 is vertically arranged, and its heat exchanger part is arranged in the air duct. The refrigerant pipeline passes through the partition and is connected to the compressor of the dehumidifier. The refrigerant heat exchanger 1 is used as an evaporator. A water receiving structure is arranged at the lower part of the dehumidifier assembly. The water receiving structure includes a first water receiving tray arranged at the lower part of the refrigerant heat exchanger 1 and a second water receiving tray at the air inlet and / or air outlet of the first gas channel of the first gas-gas heat exchanger 2. The first water receiving tray is connected to the second water receiving tray, and the second water receiving tray is connected with a drain pipe, and the drain pipe communicates with a water storage container.

[0149] Since the air will be pre-cooled by the air passing through the second gas channel of the first gas-gas heat exchanger 2 when passing through the first gas channel of the first gas-gas heat exchanger 2, the moisture in the air condenses into condensed water during the process of the air passing through the first gas channel of the first gas-gas heat exchanger 2. Therefore, condensed water will be generated during the process of the air passing through the first gas channel of the first gas-gas heat exchanger 2. When the air passing through the first gas channel of the first gas-gas heat exchanger 2 passes through the refrigerant heat exchanger 1, it exchanges heat with the liquid refrigerant in the refrigerant heat exchanger 1 and is cooled by the refrigerant heat exchanger 1. The moisture in the air condenses after the air passing through the refrigerant heat exchanger 1 is cooled, and the moisture content of the air decreases. Therefore, condensed water will also be generated during the process of the air passing through the refrigerant heat exchanger 1. The water receiving structure can lead out the condensed water on the first side of the first gas-gas heat exchanger 2 and the condensed water at the refrigerant heat exchanger 1.

[0150] In specific applications, the water receiving structure includes a first water receiving tray arranged at the lower part of the refrigerant heat exchanger 1. A second water receiving tray is provided at the air inlet of the first gas channel of the first gas-gas heat exchanger 2. The condensed water generated at the refrigerant heat exchanger 1 flows down along the condenser into the first water receiving tray. The condensed water generated in the first gas channel of the first gas-gas heat exchanger 2 flows down into the second water receiving tray. The water in the first water receiving tray is led to the second water receiving tray through a drainage structure, and then the water in the second water receiving tray is discharged into the water storage container through the drain pipe connected to it.

[0151] Of course, when the air inlet on the first side of the first gas-gas heat exchanger 2 is located at the upper part, the air flows from top to bottom, and the condensed water generated on the first side of the first gas-gas heat exchanger 2 also flows towards the air outlet on the first side of the first gas-gas heat exchanger 2. At this time, the second water receiving tray is arranged at the air outlet of the first gas-gas heat exchanger 2.

[0152] Another situation is that the air duct on the first side of the first gas-gas heat exchanger 2 is horizontally arranged. At this time, both the air inlet and the air outlet on the first side of the first gas-gas heat exchanger 2 are in the horizontal position. At this time, second water receiving trays can be arranged at the air inlet and the air outlet of the first gas channel of the first gas-gas heat exchanger 2 at the same time. The first water receiving tray is connected to a second water receiving tray close to it through a drainer. Both second water receiving trays are connected to the water storage container through a drain pipe, and the generated condensed water is discharged into the water storage container.

[0153] In the air duct of the dehumidifier in the embodiment, there is also a condenser (not marked in the figure) located at the air supply port 52. The air is heated by the condenser at the air supply port 52 and then discharged from the air supply port 52.

[0154] Since the air is cooled when passing through the refrigerant heat exchanger 1 for dehumidification, the moisture in the air is condensed. The temperature of the air after passing through the refrigerant heat exchanger 1 for dehumidification is very low. Although it is preheated by the air on the first side of the first gas-gas heat exchanger 2 when passing through the second gas channel of the first gas-gas heat exchanger 2, the temperature obtained by the air passing through the second side of the first gas-gas heat exchanger 2 from the air passing through the first side of the first gas-gas heat exchanger 2 is limited. Therefore, when the air is discharged from the second side of the first gas-gas heat exchanger 2, the temperature is still relatively low. When such air is directly introduced into the room and contacts the human body, it will cause discomfort. Therefore, the dehumidifier in this embodiment is provided with a condenser at the position of the air supply port 52 in the air duct. The air discharged through the air duct d, the air duct f, or both the air duct d and the air duct f must be heated by the condenser before being discharged through the air supply port 52 on the housing 5. By setting the temperature increase value, the air heated by the condenser will be close to the set temperature and then discharged from the air supply port 52. Such air blown on the human body will not make the human body feel uncomfortable and can also keep the indoor temperature stable.

[0155] Another embodiment of the dehumidifier of the present invention is that in this embodiment, the first gas-gas heat exchanger 2 is horizontally arranged in the air duct, and the air passes through the first gas channel and / or the second side of the first gas-gas heat exchanger 2; the refrigerant heat exchanger 1 is horizontally arranged, and its heat exchanger part is arranged in the air duct. The refrigerant pipeline passes through the partition and is connected to the compressor of the dehumidification unit. The refrigerant heat exchanger 1 is used as an evaporator; the first gas-gas heat exchanger 2 is located above the refrigerant heat exchanger 1, and a water receiving structure is arranged below the refrigerant heat exchanger 1. The water receiving structure is provided with a drain pipe, and the drain pipe is communicated with the water storage container.

[0156] The dehumidifier of this embodiment only differs in the setting methods of the first gas-gas heat exchanger 2 and the refrigerant heat exchanger 1. When the dehumidifier is a wall-mounted type and is hung indoors, the first gas-gas heat exchanger 2 is horizontally arranged in the air duct, and the refrigerant heat exchanger 1 is horizontally arranged in the air duct and is located below the first gas-gas heat exchanger 2. The gas-liquid separation component of the dehumidifier in the second embodiment still has the first mode, the second mode, the third mode, and the static dehumidification mode. The condensed water generated by the first gas-gas heat exchanger 2 can directly flow onto the refrigerant heat exchanger 1, and then, together with the condensed water generated by the refrigerant heat exchanger 1, flow towards the first water receiving tray, be collected by the first water receiving tray, and be discharged into the water storage container through the drain pipe connected to the first water receiving tray.

[0157] The dehumidifier of this embodiment can be applied to industrial occasions, such as textile factories, etc. During the production process of textile factories, waste gas will be generated to pollute the internal air. Therefore, usually, there are exhaust fans in textile factories continuously exhausting the air in the workshop to the outside and continuously introducing new air. Since textile factories have relatively high requirements for the temperature and humidity of the air, the humidity of the new air introduced into the workshop is required to be about 80%, and the air temperature is 24 - 28 degrees. Therefore, in the case of humid external air, this dehumidifier can dehumidify the external fresh air and then introduce it into the textile factory. And because the fresh air is cooled during the dehumidification process, a condenser is arranged at the air supply outlet 52 of the dehumidifier of this embodiment. Through the heating of the condenser, the air discharged from the air supply outlet 52 can meet the requirements of the textile factory for the air temperature inside.

[0168] Please review. Figure 5 and Figure 12 , such as Figure 5 and Figure 12 shown, when the fresh air dehumidifier dehumidifies the fresh air in the third mode using the gas-liquid separation component, the first air valve component 3 simultaneously opens the air ports near the first section of the refrigerant heat exchanger 1, and the second air valve component 4 opens the air ports near the second section of the refrigerant heat exchanger 1.

Figure 5 and Figure 12 , such as Figure 5 and Figure 12 shown, in the third mode, the dehumidification method of the fresh air dehumidification component is to first pass the fresh air through the second gas-gas heat exchanger 10. At the second gas-gas heat exchanger 10, the fresh air can be heated by the exhaust air passing through the second side of the second gas-gas heat exchanger 10 or cooled by the exhaust air on the other side of the second gas-gas heat exchanger 10. The cooling or heating depends on the temperatures of the fresh air and the exhaust air. When operating the dehumidification operation in summer, the fresh air obtains cold energy from the exhaust air, reducing the temperature, and at the same time is dried by the exhaust air, reducing the moisture content of the fresh air; in this way, through the total heat exchange process of the second gas-gas heat exchanger 10, the exhaust air and the incoming fresh air are used for heat and moisture exchange to recover energy, enabling the fresh air to recover energy from the exhaust air, pre-cooling and preliminarily dehumidifying the fresh air.

The air entering the air duct b enters the air duct a , and then enters the second gas channel of the first gas-gas heat exchanger 2 from the air duct e , and then flows from the air duct e into the second gas channel of the first gas-gas heat exchanger 2, and finally is discharged from the air duct f. When the air passes through the second gas channel of the first gas-gas heat exchanger 2, since the refrigerant heat exchanger 1 is arranged in parallel with the first gas-gas heat exchanger 2 and the refrigerant heat exchanger 1 is close to the second gas channel of the first gas-gas heat exchanger 2, the refrigerant heat exchanger 1 can dehumidify and cool the air on the second side of the first gas-gas heat exchanger 2.
