Example Embodiment
[0044] Implementation mode one:
[0045] Such as Figure 1 to Figure 2 As shown, the throttling element includes two first one-way valves 51 and a second one-way valve 52 that are connected in parallel and facing opposite directions. The check valve only allows refrigerant to flow in one direction. The compressor 4 is a bidirectional compressor 4 that allows the refrigerant to flow in a forward or reverse direction, that is, the compressor 4 can control the refrigerant to flow in two different directions. The compressor 4 and the throttle element are respectively connected to the two ends of the first heat exchanger 1 to form a refrigerant flow circuit. When the compressor 4 causes the refrigerant to flow in the forward direction, the refrigerant passes through the first check valve 51, and when the compressor 4 causes the refrigerant to flow in the reverse direction, the refrigerant passes through the second check valve 52, so that the cooling The circulation of the agent form...
Example Embodiment
[0051] Implementation mode two:
[0052] Such as Figure 3 to Figure 4 As shown, the throttling element includes two parallel-oriented first one-way valves 51 and second one-way valves 52 facing in opposite directions, and the compressor 4 is a one-way compressor 4 that allows only one-way flow of refrigerant. . In this embodiment, since the one-way compressor 4 is used, the temperature control system in this embodiment further includes a four-way valve 53. The four-way valve 53 includes an inlet and an outlet respectively connected to both ends of the compressor 4, and two other communication ports respectively connected to the first heat exchanger 1 and the second heat exchanger 2. In this embodiment, the inlet of the four-way valve 53 refers to the end where the refrigerant flows out, and the outlet of the four-way valve 53 refers to the end where the refrigerant flows in.
[0053] When the inlet of the four-way valve 53 is connected to the first heat exchanger 1 and the outle...
Example Embodiment
[0059] Implementation mode three:
[0060] Such as Figure 5 to Figure 6 As shown, the throttling element is a two-way valve 54, the compressor 4 is a two-way compressor 4 that allows refrigerant to flow in the forward or reverse direction, and the compressor 4 and the two-way valve 54 are respectively connected to the first converter Both ends of the heat exchanger 1; so that when the compressor 4 makes the refrigerant flow forward or reverse, the refrigerant can pass through the two-way valve 54.
[0061] In the third embodiment, the two-way compressor 4 and the two-way valve 54 that allow the refrigerant to flow in both directions are used, so that when the compressor 4 controls the refrigerant to change the flow direction, the two-way valve 54 can allow the refrigerant to pass.
[0062] In the third embodiment, the “controlling the forward flow of refrigerant and flowing from the second heat exchanger to the first heat exchanger” includes:
[0063] Control the compressor to run fo...
