Embodiment 1

[0031] see figure 2 In order to realize the cooling / heating cycle, the refrigerant circulates along the positive flow path, that is, whether it is cooling or heating, the refrigerant flows along the direction from the inlet to the outlet of the condenser and evaporator. The technical scheme of embodiment 1 is: the air conditioner refrigerant circulation system of three four-way valves comprises compressor 1, four-way valve one 3, condenser 5, throttling device 6 and evaporator connected by refrigerant pipeline 10 8. Four-way valve one 3 is existing in the refrigerant circulation system, and four-way valve two 4 and four-way valve three 11 are also provided in the refrigerant circulation system, four-way valve one 3, four-way valve two 4 and four-way valve three 11 can adopt the four-way valve of identical structure. The connection relationship of four-way valve one 3, four-way valve two 4 and four-way valve three 11 in the system is that the S pipe of four-way valve two 4 is...

Embodiment 2

[0037] see figure 1 , an air conditioner refrigerant circulation system with two four-way valves, including a compressor 1 connected by a refrigerant pipeline 10, a four-way valve 3, a condenser 5, a throttling device 6 and an evaporator 8, and a four-way valve 1 3 is existing in the refrigerant circulation system. Four-way valve 2 4 is configured in the refrigerant circulation system. The S pipe of the four-way valve 2 4 is connected to the C pipe of the four-way valve 1 3. Pipe E is connected to condenser inlet 5-1, pipe C of four-way valve 24 is connected to condenser outlet 5-2, pipe D of four-way valve 24 is connected to one end of throttling device 6, and pipe of throttling device 6 The other end is connected to the evaporator inlet 8-1, the S pipe of the four-way valve 1 is connected to the suction pipe of the compressor 1, the E pipe of the four-way valve 1 is connected to the evaporator outlet 8-2, and the four-way valve 1 is connected to the suction pipe of the compr...

Abstract

The invention provides an air conditioner refrigerant circulating system comprising two or three four-way valves and an air conditioner, which can solve the problems of difficulty of balancing the heat exchange efficiency of a heat exchanger during refrigerating/heating circulation and insufficient heating quantity existing in the prior art. When two or three four-way valves are configured in the system, the flow direction of a refrigerant in indoor and outdoor heat exchangers can be adjusted through the four-way valves, so that the refrigerating/heating flows along the same flow path to exchange heat; and in the refrigerating/heating circulation, the refrigerant can circulate along the optimal flow path, so that the efficiency of the heat exchanger can be brought into full play, and balancing of the refrigeration and heating can be realized.

Description

technical field [0001] The invention belongs to the technical field of air-conditioning and refrigeration engineering, and in particular relates to a refrigerant circulation system when a plurality of four-way valves control the operation of an air-conditioner. Background technique [0002] Existing household air conditioners usually use a four-way valve to switch between cooling and heating. When the four-way valve is not energized, it operates in a cooling state; when the four-way valve is energized, it operates in a heating state. [0003] During refrigeration, the refrigerant flows out from the compressor through the four-way valve, enters from the inlet of the outdoor condenser, flows out from the outlet of the condenser, enters from the inlet of the indoor evaporator, flows out from the outlet of the evaporator, and returns to the refrigerant through the four-way valve. compressor. [0004] When heating, the refrigerant flows out from the compressor through the four-w...
