[0039] Combine the following Figure 1-Figure 2 The utility model describes a fresh air component and an air conditioner.

[0040] According to the embodiment of the first aspect of the present utility model, referring to Figure 1 and Figure 2 As shown, the fresh air assembly provided by the utility model mainly includes: a fresh air duct 1 and a booster fan 2. The fresh air duct 1 includes: a fresh air inlet 101, an air outlet 102 and at least one indoor mixed air inlet 103, the fresh air inlet 101 is arranged at the first end of the fresh air duct 1 and is located outdoors, the air outlet 102 is arranged at the second end of the fresh air duct 1 and is located indoors, and the indoor mixed air inlet 103 is arranged in the middle of the fresh air duct 1 and is located indoors; the booster fan 2 is arranged in the fresh air duct 1 and is located at one end close to the air outlet 102.

[0041] Specifically, in addition to the outdoor fresh air inlet 101, the fresh air duct 1 also has an indoor mixed air inlet 103 in the middle, so that the outdoor fresh air can be pre-mixed with the indoor air before entering the room. In this way, by mixing part of the indoor air, the temperature of the fresh air can be adjusted to make it closer to the indoor ambient temperature, thereby reducing the indoor temperature fluctuation caused by the introduction of a large amount of unevenly cold and hot outdoor fresh air.

[0042] Furthermore, considering that a large pressure loss may occur in the process of fresh air being transported through the pipeline, the utility model arranges a booster fan 2 at one end of the fresh air duct 1 near the air outlet 102 to ensure that the mixed wind can be blown to every corner of the room with sufficient pressure, thereby ensuring the supply and coverage of fresh air, and further promoting the mixing of indoor air and fresh air, thereby improving the temperature control effect.

[0043] The fresh air component provided by the embodiment of the utility model not only realizes long-distance air supply, but also can reduce the direct impact of the fresh air on the indoor temperature to a large extent, thereby providing users with a more comfortable indoor environment and improving the user experience.

[0044] According to one embodiment of the present invention, referring to Figure 1 As shown, a plurality of indoor mixed air inlets 103 are arranged side by side and spaced apart along the length direction of the fresh air duct 1 .

[0045] Specifically, indoor air can be introduced at different positions of the fresh air duct 1 through a plurality of indoor mixed air inlets 103 arranged side by side and at intervals, so that the fresh air and indoor air can be mixed more fully and evenly, thereby improving the accuracy and efficiency of temperature regulation.

[0046] Since the indoor temperature may be unevenly distributed to a certain extent, multiple indoor mixed air inlets 103 can draw indoor air from different positions for mixing, which helps to better balance the fresh air temperature and the overall indoor temperature and achieve more refined temperature control.

[0047] In addition, valves can be set at each indoor mixed air inlet 103 to flexibly adjust the opening and closing and air intake ratio of each indoor mixed air inlet 103 according to actual conditions, which can better cope with various complex indoor environments and outdoor temperature differences and improve the adaptability of the fresh air component.

[0048] Therefore, the fresh air component provided in the embodiment of the utility model can effectively solve the problem of the influence of the introduction of fresh air on the indoor temperature caused by the temperature difference between indoor and outdoor, and significantly improve the user's comfort experience.

[0049] According to one embodiment of the present invention, referring to Figure 1 As shown, the fresh air duct 1 is arranged horizontally, and the indoor mixed air inlet 103 is arranged on the upper side of the fresh air duct 1.

[0050] According to one embodiment of the present invention, referring to Figure 1 As shown, the fresh air component of the utility model further includes: a drying filter screen 3 , and the drying filter screen 3 is arranged in the fresh air duct 1 .

[0051] In the fresh air assembly provided by the utility model, a key component, a drying filter 3, is added. The main functions and advantages of the drying filter 3 are as follows:

[0052] 1. Dehumidification: When fresh air from outside enters, especially in cooling mode, the moisture in the air may condense into dew due to the drop in temperature. The drying filter 3 can effectively absorb and remove part of the moisture in the fresh air, reduce the humidity of the air, and thus avoid or reduce the occurrence of condensation.

[0053] 2. Purification and filtration: The dry filter 3 also has a certain air purification effect, which can filter out pollutants such as particles and dust carried in the fresh air, improve the quality of the fresh air introduced into the room, and help maintain the indoor air quality.

[0054] 3. Protect equipment: By pre-treating the humid air, condensation droplets can be prevented from directly adhering to the indoor unit housing, which not only avoids potential damage to electrical equipment, but also helps to keep the appearance of the indoor unit clean and extend the service life of the equipment.

[0055] Therefore, the embodiment of the utility model can improve the safety and stability of the air conditioner and optimize the comfort of the indoor environment by integrating the drying filter 3.

[0056] According to an embodiment of the present invention, a plurality of drying filter screens 3 are arranged side by side and spaced apart along the length direction of the fresh air duct 1. For example, two or three drying filter screens 3 may be arranged.

[0057] Specifically, by arranging a plurality of drying filters 3 in the fresh air duct 1, the fresh air continuously entering can be subjected to multiple dehumidification treatments, thereby ensuring that the fresh air can be sufficiently dried during the transportation process and effectively suppressing the occurrence of condensation.

[0058] Furthermore, each dry filter 3 can intercept and adsorb particulate matter, dust and some harmful substances in the air, and the spaced arrangement of multiple filters can more comprehensively capture and remove pollutants, thereby significantly improving the purification quality of fresh air.

[0059] Therefore, the embodiment of the utility model improves the effect of fresh air pretreatment and provides users with a more comfortable and healthy indoor environment.

[0060] According to one embodiment of the utility model, referring to Figure 1 As shown, the bottom end of the drying filter screen 3 extends to the outside and below of the fresh air duct 1 ; the fresh air component also includes: a water collecting tray 4 , which is arranged below the bottom end of the drying filter screen 3 .

[0061] Specifically, when the humid air passes through the drying filter 3, the moisture therein will be adsorbed by the filter and condensed into liquid water droplets. Since the bottom end of the drying filter 3 extends above the water collection tray 4, the formed condensed water can directly drip into the water collection tray 4, thus preventing the moisture from accumulating on the filter and affecting its dehumidification and purification performance.

[0062] By collecting the water discharged from the filter screen through the water collecting tray 4, the condensed water can be effectively stored in a centralized manner to prevent the water from directly leaking into the room or into the air-conditioning equipment, causing electrical short circuits or other safety hazards.

[0063] Therefore, the design of the fresh air component cleverly combines the functions of the drying filter 3 and the water collecting tray 4, which not only ensures the effective dehumidification and purification of the fresh air, but also solves the problem of condensed water discharge.

[0064] According to an embodiment of the utility model, the water collecting tray 4 is provided with a drain port, and the drain port is connected to a drain pipe.

[0065] Specifically, the drainage port of the water collecting tray 4 can be connected to the water collecting tank through a drainage pipe to form a complete water recycling system.

[0066] The drain outlet ensures that the condensed water in the water collecting tray 4 can be discharged promptly and effectively, and flows into the water collecting tank for storage through the drainage pipe, thus avoiding the safety hazards and possible microbial breeding problems caused by water accumulation.

[0067] After the condensed water entering the water collection tank is processed by the purifier installed inside, its water quality can reach a certain cleanliness standard and then be used for domestic water, such as flushing toilets, watering plants or performing some cleaning work for non-drinking water purposes, thereby realizing the recycling of water resources and achieving the goals of energy conservation, emission reduction and green environmental protection.

[0068] According to the embodiment of the second aspect of the present utility model, referring to Figure 2 As shown, the utility model also provides an air conditioner, which can be a duct air conditioner, mainly including: an indoor unit, an outdoor unit and the fresh air assembly of the above embodiment. Among them, the indoor unit includes an evaporator 5, the outdoor unit includes a compressor 6, a throttle 7 and a condenser 8, and the compressor 6, the evaporator 5, the throttle 7 and the condenser 8 are circulated and connected through a refrigerant main circuit 9 to form a refrigeration or heating circulation loop; the fresh air assembly is arranged side by side in the indoor unit.

[0069] Specifically, after the fresh air is processed by the fresh air component, it is mixed with the airflow generated by the indoor unit to ensure that the air delivered into the room reaches a suitable temperature while maintaining good humidity and cleanliness, thereby greatly improving the user's comfort experience and realizing the organic combination of fresh air introduction and air conditioning function, so that the air conditioner can improve indoor air quality while providing temperature regulation.

[0070] According to one embodiment of the utility model, referring to Figure 2 As shown, the outdoor unit also includes: a refrigerant auxiliary circuit 10, both ends of which are connected to the refrigerant main circuit 9 between the evaporator 5 and the throttle 7, an auxiliary heat exchanger 11, a first valve 12 and a second valve 13 are provided in the refrigerant auxiliary circuit 10, the auxiliary heat exchanger 11 is arranged side by side at the fresh air inlet 101 of the fresh air duct 1, the first valve 12 and the second valve 13 are located at both ends of the auxiliary heat exchanger 11, and a third valve 14 is provided between the two ends of the refrigerant auxiliary circuit 10, and the third valve 14 is located in the refrigerant main circuit 9 between the evaporator 5 and the throttle 7.

[0071] In addition, the outdoor unit further includes: a fresh air fan 15 , which is arranged at a side of the auxiliary heat exchanger 11 facing away from the fresh air inlet 101 of the fresh air duct 1 .

[0072] The working principle of the air conditioner provided by the utility model is described below, which mainly includes:

[0073] When the air conditioner is running in heating mode, if the temperature difference between the outdoor ambient temperature and the user-set temperature is greater than or equal to 10°C, it means that the outdoor ambient temperature is much lower than the indoor temperature set by the user. In order to prevent the low-temperature fresh air directly introduced from causing a sharp drop in indoor temperature, the auxiliary heating function is started at this time. The specific operation is: control the first valve 12 and the second valve 13 to open, so that the refrigerant can flow through the auxiliary heat exchanger 11, and use the high-temperature refrigerant in the circulation process from the compressor 6 to the evaporator 5 to heat the fresh air. At the same time, the fresh air fan 15 is turned on and runs at a preset speed to send the heated fresh air into the fresh air duct 1.

[0074] If the temperature difference between the outdoor ambient temperature and the user-set temperature is less than 10°C, it means that the outdoor ambient temperature is closer to the indoor set temperature. Since the temperature of the fresh air itself is relatively suitable, no additional heating is required. Therefore, the auxiliary heat exchange function is turned off, that is, the first valve 12 and the second valve 13 are controlled to be closed, and the third valve 14 is opened, so that the refrigerant does not pass through the auxiliary heat exchanger 11, so as to maintain the normal efficiency of the heating cycle of the refrigerant main circuit 9.

[0075] At the same time, the fresh air fan 15 is adjusted to a lower speed to slowly introduce fresh air into the room. This can reduce the slight temperature fluctuations in the room caused by the large amount of fresh air entering in a short period of time, ensure a more constant indoor ambient temperature, improve user comfort, and save electricity.

[0076] When the air conditioner is running in cooling mode, if the temperature difference between the outdoor ambient temperature and the user-set temperature is greater than or equal to 5°C, it means that the outdoor ambient temperature is much higher than the indoor temperature set by the user. In order to avoid the introduction of fresh air directly causing the indoor temperature to rise, the auxiliary cooling function is enabled at this time. The specific operation is: control the first valve 12 and the second valve 13 to open, allowing the refrigerant to flow through the auxiliary heat exchanger 11, where the low-temperature refrigerant flowing out of the throttle 7 will absorb the heat in the fresh air, thereby cooling the fresh air. At the same time, the fresh air fan 15 is turned on and runs at a preset speed to send the cooled fresh air into the fresh air duct 1.

[0077] If the temperature difference between the outdoor ambient temperature and the user set temperature is less than 5°C, it means that the outdoor ambient temperature is close to the indoor set temperature. Since the fresh air temperature is suitable, no additional cooling treatment is required. At this time, the auxiliary heat exchange function is turned off, that is, the first valve 12 and the second valve 13 are controlled to be closed, and the third valve 14 is opened, so that the refrigerant does not pass through the auxiliary heat exchanger 11, ensuring the refrigeration cycle efficiency of the refrigerant main circuit 9.

[0078] The fresh air fan 15 is adjusted to a lower rotation speed to introduce fresh air into the room at a slower speed, which can minimize the impact of the fresh air on the indoor temperature and maintain a stable indoor microclimate.

[0079] Therefore, the air conditioner provided in the embodiment of the utility model can effectively reduce the impact of the fresh air on the overall indoor temperature by utilizing the refrigerant in the auxiliary heat exchanger 11 to heat or cool the fresh air, so that the fresh air temperature is as close to the indoor temperature as possible, and reasonably utilize the refrigerant energy under different working conditions. There is no need to use traditional electric heaters, thereby achieving the dual goals of high efficiency, energy saving and comfort, and providing a good user experience regardless of heating or cooling mode.

[0080] According to one embodiment of the utility model, referring to Figure 2 As shown, the compressor 6 is connected to the evaporator 5 and the condenser 8 via a four-way valve 16 respectively.

[0081] Specifically, the first valve port of the four-way valve 16 is connected to the exhaust port of the compressor 6, the second valve port of the four-way valve 16 is connected to the evaporator 5, the third valve port of the four-way valve 16 is connected to the condenser 8, and the fourth valve port of the four-way valve 16 is connected to the intake port of the compressor 6. By controlling the four-way valve 16, the cooling or heating mode of the air conditioner is realized.

[0082] According to one embodiment of the utility model, referring to Figure 2 As shown, a filter 17 is provided between the throttle 7 and the condenser 8 .

[0083] Such a design can filter out impurities, moisture or other harmful substances that may be carried during the refrigerant circulation process, prevent these impurities from entering components such as the throttle 7, evaporator 5 or condenser 8, avoid affecting the flow characteristics and heat exchange effect of the refrigerant, and ensure stable cooling and heating performance.

[0084] The specific types of the first valve 12, the second valve 13 and the third valve 14 of the utility model are not particularly limited, as long as they can play the role of opening and closing the flow path, for example, they can be solenoid valves.

[0085] According to one embodiment of the utility model, referring to Figure 2 As shown, the indoor unit further includes: an indoor fan 18, and the indoor fan 18 is arranged side by side with the evaporator 5 to improve the heat exchange effect.

[0086] In addition, the outdoor unit further includes: an outdoor fan 19, which is arranged side by side with the condenser 8. The outdoor fan 19 can be an axial flow fan to improve the heat exchange effect.

[0087] According to one embodiment of the utility model, referring to Figure 2As shown, the air conditioner of the utility model also includes: an indoor computer board 20 and an outdoor computer board 21. The indoor computer board 20 is arranged in the indoor unit and is respectively connected to the outdoor computer board 21, the booster fan 2 and the indoor fan 18 and other components; the outdoor computer board 21 is arranged in the outdoor unit and is respectively connected to the fresh air fan 15, the outdoor fan 19, the first valve 12, the second valve 13, the third valve 14, the four-way valve 16 and the compressor 6 and other components for controlling the operation of the air conditioner.

[0088] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
