Embodiment 1

[0034] like Figure 1 to Figure 3 As shown, the embodiment of the present invention provides a fresh air system, the fresh air system includes a housing, a water ring heat pump assembly, a first on-off valve assembly 19 and a second on-off valve assembly 20 .

[0035] Specifically, in the embodiment of the present invention, one end of the housing is provided with an air inlet 1, the other end is provided with an air supply port 10, and a ventilation cavity is provided inside the housing. The air inlet 1 of the fresh air system is communicated with the outside world, and the air supply port 10 is communicated with the inside of the machine room. During the operation of the fresh air system, the fresh air will pass through the air inlet 1, the ventilation cavity and the air supply port 10 in sequence, and then be sent to the machine room.

[0036] Further, a water-ring heat pump assembly is arranged in the ventilation cavity, and the water-ring heat pump assembly may include a...

Abstract

The invention discloses a fresh air system which comprises a water loop heat pump assembly, the water loop heat pump assembly comprises a heat exchanger, an outlet of a heat supply side is connected with an inlet of a first switch valve assembly, and a first outlet of the first switch valve assembly is connected with an inlet of a compressor through a first expansion valve and an evaporator in sequence; a second outlet of the first switch valve assembly is directly connected with an inlet of the compressor; an outlet of the compressor is connected with an inlet of a second switch valve assembly, a first outlet of the second switch valve assembly is connected with an inlet of the heat supply side through the condenser and a second expansion valve in sequence, and a second outlet of the second switch valve assembly is directly connected with the inlet of the heat supply side; and one end of the connecting pipeline is connected between the condenser and the second expansion valve, and the other end of the connecting pipeline is connected between the first expansion valve and the evaporator. Cooling, dehumidification, heating and other treatment processes of fresh air are achieved, and the fresh air requirement of a machine room is met.

Description

technical field [0001] The invention relates to the technical field of fresh air systems, in particular to a fresh air system. Background technique [0002] The computer room of the large data center of the server has fresh air demand all year round. The fresh air volume required by the personnel or the fresh air volume required to maintain the positive pressure of the computer room must be maintained in the computer room. At present, the fresh air system used in the computer room is usually equipped with a full heat exchanger, and the heat of the return air in the computer room is recovered through the full heat exchanger, so as to cool or heat the fresh air. The working principle of the total heat exchanger is: when working, the indoor exhaust air and fresh air flow through the heat exchanger core in a positive cross manner. The phenomenon of heat and mass transfer occurs when the separator is used, resulting in a total heat exchange process. When running in summer, the ...
