Embodiment 2

[0055] Such as figure 2 As shown, the difference from Embodiment 1 is that the return pipe is provided with a second branch structure to divide the return pipe into a third branch and a fourth branch, the third branch and the first compression chamber 1 The air inlet is connected, the fourth branch is connected with the second branch through the third branch structure 16 , and the outlet end of the third branch structure 16 is connected with the air supply port of the second compression chamber 2 . By setting the third flow distribution structure 16, the first compression chamber 1 and the second compressor can be connected in parallel, and two modes of parallel compression and parallel compression can be switched according to actual conditions.

[0056] Further, the second branch structure is a three-way pipe, and the third branch structure 16 is a three-way valve, wherein the three-way valve includes a first inlet and a second inlet, and the first inlet is connected to the ...

Embodiment 3

[0058] Such as image 3 As shown, the difference from Embodiment 1 is that the fresh air channel 17 and the exhaust air channel 18 are connected through the total heat exchange device 19, and the total heat exchange device 19 is located on the upstream side of the air flow passing through the dehumidification part, which can further enhance the dehumidification Effect. Such as image 3 As shown, the fresh air enters the total heat exchange device 19 from the air channel, and then enters the fresh air passage 17, the exhaust air enters the total heat exchange device 19, and the exhaust air and the fresh air exchange heat in the total heat exchange device 19, and the outdoor fresh air is pre-heated. While cooling, the energy of the indoor return air is recovered to reduce the energy consumption of the fresh air dehumidification unit.

Embodiment 4

[0060] Such as Figure 4 As shown, the difference from Embodiment 1 is that in this embodiment, a flow control device 20 is provided on the first branch, and the flow control device 20 is arranged in parallel with the third heat exchanger 8. The inlet port of the flow control device 20 The outlet end of the flow control device 20 is connected to the pipeline between the third heat exchanger 8 and the fourth heat exchanger 4 . By providing the flow control device 20 and arranging the flow control device 20 in parallel with the third heat exchanger 8 , the reheat amount can be precisely adjusted by adjusting the flow rate of the flow control device 20 .

Abstract

The invention provides a dehumidifying system and a fresh air dehumidifying machine. The system involves a compressor, a first heat exchanger (3) and a first gas-liquid separating device (9) which sequentially communicate; the compressor comprises a first compressing cavity (1) and a second compressing cavity (2); the first gas-liquid separating device (9) communicates with a first branch and a second branch, wherein a condensing part and a dehumidifying part are arranged on the first branch, and an air supplementing device is arranged on the second branch; a refrigerant in the dehumidifying system is the non-azeotropic mixed refrigerant, the first gas-liquid separating device (9) separates the refrigerant into a gas phase and a liquid phase, the gas phase refrigerant enters the first branch, the liquid phase refrigerant enters the second branch, and at least part of the refrigerant entering the second branch enters the air supplementing device; and a first exhaust port is formed in the air supplementing device, and the refrigerant is in the gas phase when being exhausted from the first exhaust port and enters the second compressing cavity (2). According to the provided dehumidifying system and the fresh air dehumidifying machine, the condensation performance and the evaporation performance of the system after air supplementing and enthalpy increasing can be effectively improved.

Description

technical field [0001] The application belongs to the technical field of air conditioning, and in particular relates to a dehumidification system and a fresh air dehumidifier. Background technique [0002] Due to the fact that some special industries cannot use return air circulation, and people's requirements for indoor air quality have improved, fresh air dehumidifiers have emerged as the times require. The fresh air dehumidifier is a dehumidification device that dehumidifies and adjusts the temperature of the external fresh air, and sends it to a specific space after meeting the requirements set by the user. The compressor in the existing fresh air dehumidification unit usually uses a single boiling point refrigerant, and after supplementing the air to increase the enthalpy, the condensation performance and evaporation performance are poor. Contents of the invention [0003] Therefore, the technical problem to be solved in this application is to provide a dehumidificat...
