[0026] The present invention provides an air conditioner. Please refer to Figures 1 to 3 , including: a fresh air duct 1, the fresh air duct 1 is used to communicate with the outside to introduce fresh air from the outside into the room; an air conditioner duct 2, the air conditioner duct 2 communicates with the room to discharge the air conditioner air into the room; a partition board 3 is arranged between the fresh air duct 1 and the air conditioner duct 2, and a fresh air passage opening 4 communicating the fresh air duct 1 and the air conditioner duct 2 is arranged on the partition board 3, so that the fresh air in the fresh air duct 1 flows through the air conditioner duct 2 to the room; a dehumidifying evaporator 5, the dehumidifying evaporator 5 is arranged in the fresh air duct 1 to perform heat exchange with the fresh air duct 1 to condense the water vapor in the fresh air; a dehumidifying condenser 6, the dehumidifying condenser 6 is arranged in the air conditioner duct 2, and the dehumidifying condenser 6 is communicated with the dehumidifying evaporator 5 to flow the refrigerant in the dehumidifying condenser 6 into the dehumidifying evaporator 5.

[0027] The air conditioner provided by the present invention includes a fresh air duct 1, an air-conditioning duct 2, a dehumidifying evaporator 5 and a dehumidifying condenser 6. The fresh air duct 1 is used to communicate with the outside to introduce fresh air from the outside into the room. The air-conditioning duct 2 communicates with the room to discharge air-conditioning air into the room. A partition plate 3 is arranged between the fresh air duct 1 and the air-conditioning duct 2. A fresh air through port 4 communicating the fresh air duct 1 and the air-conditioning duct 2 is arranged on the partition plate 3, so that the fresh air in the fresh air duct 1 flows through the air-conditioning duct 2 to the room. The dehumidifying evaporator 5 is arranged in the fresh air duct 1 to perform heat exchange with the fresh air duct 1 to condense the water vapor in the fresh air. The dehumidifying condenser 6 is arranged in the air-conditioning duct 2. The dehumidifying condenser 6 communicates with the dehumidifying evaporator 5 to allow the refrigerant in the dehumidifying condenser 6 to flow into the dehumidifying evaporator 5. When the air conditioner of the present invention dehumidifies the fresh air, there is no need to separately provide a compressor for dehumidification, saving installation space and economic costs, making the structure of the fresh air dehumidification system of the air conditioner simpler and easier to implement.

[0028] The air conditioner provided by the present invention realizes the dehumidification of fresh air in the refrigeration mode. In the refrigeration mode, the refrigerant in the dehumidifying condenser 6 is cooled by the air flow at a lower temperature in the air-conditioning duct 2. Then, the refrigerant in the dehumidifying condenser 6 flows into the dehumidifying evaporator 5 to perform heat exchange with the fresh air in the fresh air duct 1, condensing the water vapor in the fresh air to achieve the dehumidification of the fresh air. After the heat exchange, a part of the refrigerant in the dehumidifying evaporator 5 is converted into gaseous refrigerant. The gaseous refrigerant flows into the dehumidifying condenser 6 and continues to perform heat exchange with the fresh air in the air-conditioning duct 2, being converted into a liquid refrigerant at a lower temperature and flowing into the dehumidifying evaporator 5 to complete the refrigerant cycle.

[0029] Specifically, at least a part of the dehumidifying condenser 6 is opposite to the fresh air through port 4, so as to ensure that after the fresh air is cooled in the fresh air duct 1, it can fully perform heat exchange with the refrigerant in the dehumidifying condenser 6.

[0030] In the process of specific implementation, the air conditioner further includes: a connecting pipe fitting 7. The refrigerant inlet of the connecting pipe fitting 7 communicates with the dehumidifying condenser 6, and the refrigerant outlet of the connecting pipe fitting 7 communicates with the refrigerant inlet of the dehumidifying evaporator 5. To realize the refrigerant cycle between the dehumidifying condenser 6 and the dehumidifying evaporator 5 through the connecting pipe fitting 7.

[0031] Preferably, there are multiple connecting pipe fittings 7, and the multiple connecting pipe fittings 7 are arranged side by side on the side of the dehumidifying condenser 6.

[0032] To make the structure of the air conditioner simpler, the connecting pipe fitting 7 is inclined relative to the horizontal plane, so that the refrigerant in the dehumidifying condenser 6 flows into the dehumidifying evaporator 5 under the action of gravity. Further, the vaporized refrigerant in the dehumidifying evaporator 5 can also directly disperse into the dehumidifying condenser 6 through the connecting pipe fitting 7.

[0033] To ensure that the fresh air in the fresh air duct 1 can flow into the air-conditioning duct 2, the air conditioner further includes: an induced draft fan 8, which is arranged in the fresh air duct 1, and at least part of the induced draft fan 8 faces the fresh air through port 4, so as to introduce the fresh air in the fresh air duct 1 into the air-conditioning duct 2.

[0034] Specifically, the induced draft fan 8 is arranged on the side of the dehumidifying evaporator 5 away from the partition plate 3. This setting can avoid interference between the induced draft fan 8 and the partition plate 3 or the dehumidifying evaporator 5, and at the same time facilitate the installation of the induced draft fan 8.

[0035] In a specific implementation, the air conditioner further includes: an air-conditioning evaporator 9, which is arranged in the air-conditioning duct 2, and at least part of the dehumidifying condenser 6 is attached to the air-conditioning evaporator 9. This setting can enhance the heat exchange between the dehumidifying condenser 6 and the fresh air in the air-conditioning duct 2, and at the same time enable heat exchange to be formed between the air-conditioning evaporator 9 and the dehumidifying condenser 6, further cooling the refrigerant in the dehumidifying condenser 6.

[0036] In the embodiment provided by the present invention, the air conditioner further includes: a fresh air inlet, which is communicated with the fresh air duct 1, and outdoor fresh air flows into the fresh air duct 1 through the fresh air inlet; at least part of the dehumidifying evaporator 5 faces the fresh air inlet. So that the fresh air flowing into the fresh air duct 1 through the fresh air inlet can fully exchange heat with the dehumidifying evaporator 5 to ensure the dehumidification effect on the fresh air.

[0037] Specifically, the air conditioner further includes: an air-conditioning condenser 10, at least part of which is installed in the fresh air duct 1, and the dehumidifying evaporator 5 is arranged opposite to and spaced apart from the air-conditioning condenser 10. So that the high-temperature gas around the air-conditioning condenser 10 will not affect the dehumidifying evaporator 5 and improve the dehumidification effect of the dehumidifying evaporator 5.

[0038] During the specific use process, the air conditioner further includes: a cross-flow impeller 11, which is arranged in the air-conditioning duct 2 and is rotatably arranged to introduce the fresh air in the air-conditioning duct 2 into the room. Among them, the dehumidifying condenser 6 is arranged on the side of the cross-flow impeller 11. During the rotation of the cross-flow impeller 11, the fresh air in the air-conditioning duct 2 is introduced into the room, and at the same time the fresh air fully exchanges heat with the dehumidifying condenser 6.

[0039] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0040] The air conditioner provided by the present invention includes a fresh air duct 1, an air-conditioning duct 2, a dehumidifying evaporator 5, and a dehumidifying condenser 6.

The dehumidifying evaporator 5 is arranged in the fresh air duct 1 to perform heat exchange with the fresh air duct 1 to condense the water vapor in the fresh air. The dehumidifying condenser 6 is arranged in the air-conditioning duct 2, and the dehumidifying condenser 6 communicates with the dehumidifying evaporator 5 to allow the refrigerant in the dehumidifying condenser 6 to flow into the dehumidifying evaporator 5. When the air conditioner of the present invention dehumidifies the fresh air, there is no need to separately provide a compressor for dehumidification, saving installation space and economic costs, making the structure of the fresh air dehumidification system of the air conditioner simpler and facilitating implementation.
