Description

Technical Field

[0001] The utility model relates to an air conditioning system, in particular to a refrigerant passage switcher and an air conditioning system using the refrigerant passage switcher. Background Art

[0002] The air conditioner uses a compressor to drive the refrigerant to circulate between the evaporator and the condenser radiator to achieve the cooling and heating effects. A large amount of energy is consumed during heating, so people think of combining air conditioning with heating. Using heating for heating in winter can achieve energy-saving effects. However, the flow paths of the refrigerant are different in the cooling and heating states, and valves need to be set in the connecting passages. Some valves need to be manually opened or closed when switching states, which is troublesome due to damage. Utility Model Content

A second one-way valve is provided in the middle of the third tube. The second one-way valve only allows the refrigerant to flow from end A to end B.

[0006] The advantage of the refrigerant path switcher is that during cooling and heating, the two one-way valves in the refrigerant path switcher automatically switch states and work in coordination to control the refrigerant switching path in the path, eliminating manual switching.

DETAILED DESCRIPTION

[0010] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0011] like Figure 1 The refrigerant passage switcher shown includes a first tube 1 and a second tube 2. A one-way valve 401 is provided in the middle of the first tube 1, which only allows the refrigerant to flow from the B end to the A end. The first tube 1 is connected to the third tube 3 on the side of the one-way valve 401 close to the B end, and the other end of the third tube 3 is connected to the second tube 2. A one-way valve 402 is provided in the middle of the third tube 3, which only allows the refrigerant to flow from the A end to the B end.

[0012] An energy-saving air-conditioning system includes an air-conditioning indoor heat exchanger 6, an air-conditioning outdoor heat exchanger 5, a refrigerant path switcher, a heater 7, and a heater heat exchanger 701. The first tube 1 at the B end of the refrigerant path switcher is connected to the outlet of the air-conditioning outdoor heat exchanger 5, the second tube 2 at the B end of the refrigerant path switcher is connected to the inlet of the air-conditioning indoor heat exchanger 6, the first tube 1 at the A end of the refrigerant path switcher is connected to the inlet of the heater heat exchanger 701, the second tube 2 at the A end of the refrigerant path switcher is connected to the outlet of the heater heat exchanger 701, the inlet of the air-conditioning outdoor heat exchanger 5 is connected to the outlet of the air-conditioning indoor heat exchanger 6, and the heater heat exchanger 701 is installed inside the heater 7.

[0013] When the air conditioner is cooling, the refrigerant medium is circulated in the middle. Figure 3 It shows that the refrigerant is compressed and releases heat in the air-conditioning outdoor heat exchanger 5, the pressure increases, and it flows out from the outlet of the air-conditioning outdoor heat exchanger 5, merges after passing through the one-way valves 401 and 402, and flows into the inlet of the air-conditioning indoor heat exchanger 6. After expansion and heating, it flows out from the outlet of the air-conditioning indoor heat exchanger 6 and flows into the inlet of the air-conditioning outdoor heat exchanger 5.

[0014] When heating, the air conditioner does not work, the heater works, and the circulation of the refrigerant medium is as follows Figure 4 It shows that the refrigerant is heated in the heating heat exchanger 701, the pressure increases, and it flows out from the outlet of the heating heat exchanger 701 and flows into the inlet of the air-conditioning indoor heat exchanger 6. After heat dissipation, the temperature decreases, the pressure decreases, and it flows out from the outlet of the air-conditioning indoor heat exchanger 6 and flows into the inlet of the air-conditioning outdoor heat exchanger 5. It flows out through the outlet of the air-conditioning outdoor heat exchanger 5, flows into the inlet of the heating heat exchanger 701 through the one-way valve 401, and the pressure at the B end of the one-way valve 402 is greater than the pressure at the A end, and is in a cut-off state.

[0015] When the air conditioning system is cooling or heating, the two one-way valves in the refrigerant path switcher automatically switch states and work in coordination to control the refrigerant switching path in the path, eliminating manual switching and making it very convenient to use. The air conditioner is connected to the heater, and when heating, the heat from the heater can be quickly distributed to the room, which has a good heat dissipation effect and saves energy.
