Description

Technical Field

[0001] This application relates to the field of air conditioner technology, specifically to an air conditioner. Background Technology

[0002] In certain situations, such as rooms on ships, the environment may be consistently high in humidity. When the human body is in a high-humidity environment, it dissipates heat and cools down by sweating. However, high humidity hinders the evaporation of sweat, making it difficult to regulate body temperature and causing people to feel stuffy and tired. Currently, air conditioners generally dehumidify rooms by cooling, causing the water vapor in the room to condense and form condensate, thus achieving the purpose of dehumidification. This process lowers the room temperature, which means that in seasons with suitable temperatures, such as early spring or late autumn, once the air conditioner is used for dehumidification, users will feel that the room is very cold, affecting their experience.

It should be understood that those skilled in the art will recognize that this application can be made without using these specific details.

Therefore, this application is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0031] In certain situations, such as rooms on ships, the environment may be consistently high in humidity. When the human body is in a high-humidity environment, it dissipates heat and cools down by sweating. However, high humidity hinders the evaporation of sweat, making it difficult to regulate body temperature and causing people to feel stuffy and tired. Currently, air conditioners generally dehumidify rooms by cooling, causing the water vapor in the room to condense and form condensate, thus achieving the purpose of dehumidification. This process lowers the room temperature, which means that in seasons with suitable temperatures, such as early spring or late autumn, once the air conditioner is used for dehumidification, users will feel that the room is very cold, affecting their experience.

[0032] For this, please refer to Figure 1 Some embodiments of this application provide an air conditioner 100, which includes: an indoor terminal 10, a refrigerant circulation path 20, a first cooling water flow path 30, and a switching device. The refrigerant circulation path 20 is provided with a condenser 21, a compressor 22, and an evaporator 23. The first cooling water flow path 30 includes a heat exchange flow section 31, a first water outlet flow section 32, and a second water outlet flow section 33. The heat exchange flow path is used for heat exchange with the condenser 21. The first water outlet flow section 32 is at least partially located at the indoor terminal 10, and the second water outlet flow section 33 is located outside the indoor terminal 10. The switching device is disposed in the first cooling water flow path 30 and is used to selectively guide the cooling water flowing out of the heat exchange flow path to one of the first water outlet flow section 32 and the second water outlet flow section 33.

[0033] It should be noted that the evaporator 23 can be installed at the indoor terminal 10 to directly exchange heat and cool the room. Alternatively, it can be installed outside the room to first cool the heat exchange medium, and then allow the heat exchange medium to absorb heat at the indoor terminal 10 to cool the room, etc. There are no limitations here. The first cooling water flow path 30 can be a circulating flow path, that is, the cooling water circulates in the first cooling water flow path 30. It can also be an open flow path with a cooling water inlet 34 and a cooling water outlet 35, with cooling water flowing in from the cooling water inlet 34 and flowing out from the cooling water outlet 35, etc. There are no limitations here.

[0034] The specific implementation of the switching device is not limited. It can be in the form of a three-way valve, multiple single-way valves, or a switching valve 40, etc., and is not limited here.

[0035] The second water outlet section 33 is located outside the indoor terminal 10, so that the cooling water heated in the second water outlet section does not flow through the indoor terminal 10, thus avoiding the impact on the indoor ambient temperature when the air conditioner 100 is cooling the room. Specifically, when the first cooling water flow path 30 is a circulating flow path, the cooling water flowing out of the second water outlet section 33 can be directly guided to the heat exchange flow path 31 for reheating; of course, it can be directly discharged, for example, when the air conditioner 100 is installed on a ship, it can be directly discharged into rivers, lakes and seas; etc., without limitation.

[0036] The first water outlet flow section 32 is at least partially located at the indoor terminal 10. Therefore, when the cooling water flowing out of the heat exchange flow path enters the first water outlet flow section 32, it heats the airflow passing through the indoor terminal 10. In seasons with suitable temperatures, such as early spring or late autumn, the cooling capacity of the evaporator 23 can be used to dehumidify the room first, and then the portion of the first water outlet flow section 32 located at the indoor terminal 10 can be used to heat the dehumidified air, thus avoiding large fluctuations in indoor temperature during dehumidification. Furthermore, the heat from the condenser 21 in the refrigerant circulation path 20 can be directly utilized, eliminating the need for an additional heat source 61 to heat the air, reducing energy efficiency and saving costs.

[0037] In the scheme of this embodiment, by setting the first cooling water flow path 30 and the switching device, in the hot summer season, the switching device can directly direct the cooling water flowing out of the heat exchange flow path to the second water outlet flow path 33, thereby achieving cooling and dehumidification of the room. In the early spring or late autumn seasons with suitable temperatures, the cooling capacity of the evaporator 23 can be used to dehumidify the room first, and then the first water outlet flow path 32 located at the indoor terminal 10 can be used to heat the dehumidified air, thereby avoiding large fluctuations in indoor ambient temperature during the dehumidification process and improving the user's dehumidification experience.

[0038] In some embodiments, the switching device includes two switching valves 40, which are respectively disposed in the first water outlet section 32 and the second water outlet section 33.

[0039] Specifically, the implementation of the switching valve 40 is not limited; it can be a two-way valve, an electric shut-off valve, etc., and is not limited here.

[0040] In the scheme of this embodiment, by setting the switching device as two switching valves 40, when it is necessary for the first water outlet flow section 32 to be open and the second water outlet flow section 33 to be closed, the switching valve 40 located in the first water outlet flow section 32 can be opened and the switching valve 40 located in the second water outlet flow section 33 can be closed. Conversely, when it is necessary for the second water outlet flow section 33 to be open and the first water outlet flow section 32 to be closed, the switching valve 40 located in the second water outlet flow section 33 can be opened and the switching valve 40 located in the first water outlet flow section 32 can be closed. In this way, the switching between the two water outlet flow sections can be stably realized.

[0041] Of course, in some embodiments, the water flow rate in the outlet flow section can also be controlled by controlling the opening degree of the switching valve 40. For example, in one embodiment, the switching valve 40 located in the second outlet flow section 33 and the switching valve 40 located in the first outlet flow section 32 are each opened to 50%, so that half of the cooling water flows to the first outlet flow section 32 and the other half of the cooling water flows to the second outlet flow section 33.

[0042] In addition, in some embodiments, the heat exchange flow section 31 is provided with a cooling water inlet 34, and the first water outlet flow section 32 and the second water outlet flow section 33 are both provided with cooling water outlets 35, and the cooling water inlet 34 and the cooling water outlet 35 are arranged at intervals.

[0043] It should be noted that the cooling water outlet 35 of the first water outlet section 32 and the cooling water outlet 35 of the second water outlet section 33 can be the same outlet. For example, when the air conditioner 100 is installed on a ship, the first water outlet section 32 and the second water outlet section 33 discharge cooling water into rivers, lakes, and seas through the same cooling water outlet 35. Of course, they can also be separate outlets, etc., which is not limited here.

[0044] In this embodiment, the cooling water inlet 34 and the cooling water outlet 35 are spaced apart, so that the cooling water flowing out of the cooling water outlet 35 will not directly enter the cooling water inlet 34 to participate in the next heat exchange. When the air conditioner 100 is cooling, the low-temperature cooling water can flow continuously from the cooling water inlet 34 into the first cooling water flow path 30, thereby quickly cooling the condenser 21 and improving the cooling effect of the refrigerant circulation flow path 20. Compared with the circulation flow path scheme, its cooling effect on the condenser 21 is better.

[0045] Furthermore, in some embodiments, the air conditioner 100 is a marine air conditioner 100, and when the air conditioner 100 is installed on the hull, the cooling water inlet 34 and / or the cooling water outlet 35 are used to guide the water outside the hull.

[0046] It should be noted that since ships sail on rivers, lakes, and seas, they may be in a high-humidity environment. Users on ships are easily bothered by the humidity. The air conditioner 100 provided in the embodiments of this application can not only provide cooling and dehumidification, but also achieve constant temperature and dehumidification, which greatly improves the user experience.

[0047] Since ships navigate on rivers, lakes, and seas, the cooling water inlet 34 is directed to the hull, allowing water to be drawn directly from the river, lake, or sea to cool the condenser 21, thus enabling rapid cooling of the condenser 21.

[0048] The cooling water outlet 35 is used to guide the water outside the ship, so that the water whose temperature has increased after heat exchange can be directly discharged into rivers, lakes and seas, avoiding the impact of recycling on the cooling effect of the condenser 21.

[0049] It should be noted that the evaporator 23 can be installed directly inside the room to cool the room, or it can be installed outside the room; there is no limitation on this.

[0050] In one embodiment, the air conditioner 100 further includes a cooling flow path 50, which is configured to exchange heat with the evaporator 23, and the cooling flow path 50 is provided with a cooling heat exchanger 51 located at the indoor terminal 10, and at the indoor terminal 10, the cooling heat exchanger 51 is located on the windward side of the first cooling water flow path 30.

[0051] It should be emphasized that, in the scheme of this embodiment, the evaporator 23 can be located at the indoor terminal 10 or outside the indoor terminal 10, without limitation. The refrigeration flow path 50 can be a single instance or multiple instances. When multiple instances are used, there can be multiple evaporators 23, or one evaporator 23 can cool multiple refrigeration flow paths 50, thereby achieving cooling for multiple rooms with one evaporator 23, etc., without limitation. In a further embodiment, the evaporator 23 is located outside the indoor terminal 10, allowing the refrigerant circulation path 20 to be set up more centrally, saving costs.

[0052] The cooling flow path 50 can be configured as a through path, i.e., having a flow path outlet and a flow path inlet, or it can be configured as a circulating flow path; no limitation is made here. In one embodiment, the cooling flow path 50 is a circulating flow path.

[0053] In this embodiment, by setting the cooling flow path 50, the cooling capacity of the evaporator 23 can be transferred to the cooling heat exchanger 51 to cool the room. At the indoor terminal 10, the cooling heat exchanger 51 is located on the windward side of the first cooling water flow path 30. In early spring or late autumn, when the temperature is suitable, the airflow passing through the indoor terminal 10 can be cooled by the cooling heat exchanger 51, causing the moisture in the airflow to condense and form condensate, thus completing the dehumidification of the airflow. Then, it is heated by the first cooling water flow path 30, thereby eliminating the influence of airflow temperature during the dehumidification process to a certain extent. Thus, even in early spring or late autumn when the temperature is suitable, the rooms on the ship can be dehumidified well, improving the user experience.

[0054] In some embodiments, the air conditioner 100 further includes a first heating flow path 60, on which a heat source 61 and a heating heat exchanger 62 are disposed. The heat source 61 is used to heat the medium in the first heating flow path 60, wherein the heating heat exchanger 62 is located at the indoor terminal 10 to heat the airflow flowing through the indoor terminal 10.

[0055] It should be noted that the specific implementation form of the heat source 61 is not limited. It can be in the form of electric heating, such as PTC heating, or in the form of boiler heating, or in the form of solar heating, etc., and is not limited here.

[0056] In the scheme of this embodiment, by setting the first heating flow path 60, the dehumidified air can be heated when the temperature is low, thereby achieving heating in the room. In addition, heating and dehumidifying can achieve a certain drying function. By heating the air, the relative humidity of the air is reduced significantly, making it easier for the moisture in the room to evaporate and circulate, and thus being dehumidified and removed more quickly.

[0057] Furthermore, at the indoor terminal 10, the position of the heating heat exchanger 62 is not limited. It can be located on the windward side of the cooling heat exchanger 51, that is, first heating the air and then cooling and dehumidifying it. It can also be located on the windward side of the first cooling water flow path 30 and the leeward side of the cooling heat exchanger 51, or it can be located on the leeward side of the first cooling water flow path 30, etc., and is not limited here.

[0058] In some embodiments, the cooling heat exchanger 51 is disposed on the windward side of the heating heat exchanger 62. Correspondingly, the airflow flowing in from the return air vent of the indoor terminal 10 first passes through the cooling heat exchanger 51 for cooling. At this time, the airflow can be reduced to a lower temperature, resulting in good condensation and dehumidification. Then, it passes through the first cooling water flow path 30 and the heating heat exchanger 62 for heating the room. Compared with the scheme of disposing of the cooling heat exchanger 51 on the leeward side of the heating heat exchanger 62, the dehumidification effect is better.

[0059] In a further embodiment, the heating heat exchanger 62 is located in the first cooling water flow path 30. That is, the airflow flowing in from the return air vent of the indoor terminal 10 is first cooled by the cooling heat exchanger 51, and then initially heated by exchanging heat with the first cooling water flow path 30 before being heated by the heating heat exchanger 62. With this configuration, since the temperature of the heating heat exchanger 62 can be made relatively high, the outlet air can be heated to a higher temperature, thereby effectively increasing the outlet air temperature.

[0060] In addition, in some embodiments, the air conditioner 100 further includes a second heating flow path 70 connected to the heat source 61. The second heating flow path 70 includes a heating terminal 71, which is installed in the room to heat the indoor air.

[0061] In the scheme of this embodiment, by setting the second heating flow path 70, the heat of the heat source 61 can be transferred to the heating terminal 71 through the second heating flow path 70, thereby heating the air in the room from a location outside the indoor terminal 10. On the one hand, multi-point heating is achieved, resulting in better heating effect. On the other hand, multiple heating flow paths can share a single heat source 61, saving costs.

[0062] The specific implementation of the heat source 61 is not limited. When the air conditioner 100 is installed on the ship, a boiler can be used. Boilers have high heating efficiency and are more suitable for the ship's environment.

[0063] In some embodiments, a first water pump 311 is provided on the heat exchange flow path 31. By providing the first water pump 311, the flow rate of the water in the first cooling water flow path 30 can be increased.

[0064] In some further embodiments, the cooling water inlet 34 and / or the cooling water outlet 35 are used to guide the hull body. Correspondingly, in this case, the first water pump 311 can directly draw water from rivers, lakes and seas into the first cooling water flow path 30, and can accelerate the discharge of the cooled water after heat exchange from the cooling water outlet 35.

[0065] Furthermore, the first water pump 311 is installed on the heat exchange flow section 31, which can also accelerate the flow rate of cooling water in the first outlet flow section 32 and the second outlet flow section 33. Compared with the first outlet flow section 32 or the second outlet flow section 33, its acceleration range is wider.

[0066] In some embodiments, a second water pump 52 is provided on the refrigeration flow path 50. By providing the second water pump 52, the flow rate of the heat exchange medium in the refrigeration flow path 50 can be increased, thereby improving the heat exchange effect.

[0067] In some embodiments, a third water pump 63 is provided on the first heating flow path 60, thereby increasing the flow rate of the heat exchange medium in the first heating flow path 60.

[0068] In some embodiments, a fourth water pump 72 is provided on the second heating flow path 70, thereby increasing the flow rate of the heat exchange medium in the second heating flow path 70.

Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
