Embodiment 1

[0030] Such as figure 1 As shown, the embodiment of the present invention provides a fresh air dehumidification system, including a compressor and a fresh air device, and the compressor communicates with the fresh air device; the compressor includes a low-temperature compression chamber 1, a high-temperature compression chamber 2 and an auxiliary compression chamber 3. The exhaust port of chamber 1 and the exhaust port of high-temperature compression chamber 2 and the exhaust port of auxiliary compression chamber 3 are set independently of each other, and the suction port of low-temperature compression chamber 1 and the suction port of high-temperature compression chamber 2 are set independently of each other. The compression chamber 1 and the auxiliary compression chamber 3 are arranged in parallel, and the exhaust port of the low-temperature compression chamber 1 communicates with the exhaust port of the auxiliary compression chamber 3. Since there are three independent compr...

Embodiment 2

[0050] Such as figure 2 As shown, the difference between this embodiment and Embodiment 1 is that: the input end of the low-temperature evaporator 7 communicates with the connecting pipeline 20, and a first throttling capillary 23 is arranged between the low-temperature evaporator 7 and the connecting pipeline 20; The output end of the device 9 is communicated with a second throttling capillary 24 for cooling.

[0051] A fourth electromagnetic valve 17 and a fifth electromagnetic valve 18 are also arranged between the reheater 5 and the low temperature evaporator 7, the fourth electromagnetic valve 17 is communicated between the input end of the reheater 5 and the low temperature evaporator 7, and the fifth electromagnetic valve 17 is connected between the input end of the reheater 5 and the low temperature evaporator 7 The solenoid valve 18 is connected between the output end of the reheater 5 and the low temperature evaporator 7 .

[0052] The operating mode of the refrige...

Embodiment 3

[0056] Such as image 3 As shown, the difference between this embodiment and Embodiment 1 is that the fresh air device includes a fresh air duct 21 and an exhaust duct 22, an intersection is provided between the fresh air duct 21 and the exhaust duct 22, and the intersection is set There is a total heat exchanger, the total heat exchanger 25 for indoor low-temperature exhaust air and outdoor introduction of high-temperature fresh air.

[0057] The advantage of this embodiment is that the outdoor fresh air can be exchanged with the indoor return air, and part of the heat of the indoor return air can be recovered to further improve the energy efficiency of the system.

[0058] Compared with the prior art, the beneficial effects of the present invention are as follows: Since there are three independent compression chambers, which are respectively a low-temperature compression chamber, a high-temperature compression chamber and an auxiliary compression chamber, all three compressi...

Abstract

The invention provides a fresh air dehumidification system. A compressor and a fresh air device are included, and the compressor communicates with the fresh air device. The compressor comprises a low-temperature compression cavity, a high-temperature compression cavity and an auxiliary compression cavity. An exhaust port of the low-temperature compression cavity, an exhaust port of the high-temperature compression cavity and an exhaust port of the auxiliary compression cavity are independently arranged. An air suction port of the low-temperature compression cavity and an air suction port of the high-temperature compression cavity are independently arranged. The low-temperature compression cavity and the auxiliary compression cavity are arranged in parallel. The exhaust port of the low-temperature compression cavity communicates with the exhaust port of the auxiliary compression cavity. The fresh air dehumidification system can adapt to the wider running work condition, the system advantage is brought into full play, and the dehumidification energy efficiency is further effectively improved.

Description

technical field [0001] The invention relates to the technical field of fresh air air conditioners, in particular to a fresh air dehumidification system and an air conditioner. Background technique [0002] In the fresh air dehumidification system, a system with independent temperature and humidity control is often used, that is, when the fresh air is used to replace the indoor exhaust air, the fresh air is first cooled by the high-temperature evaporator, and then the fresh air is dehumidified by the low-temperature evaporator. to meet comfort requirements. [0003] However, the fresh air dehumidification system with dual evaporating temperatures at the present stage has high energy efficiency only under a certain working condition. The system energy efficiency is low. Contents of the invention [0004] In view of this, the purpose of the present invention is to avoid the deficiencies in the prior art and provide a fresh air dehumidification system, which can adapt to wid...
