Referring to fig. 1 to 4, specifically, when the refrigerant circulation system is in the cooling mode, the first heat exchanger 4 functions as a condenser, the second heat exchanger 6 functions as an evaporator, the inlet 31 of the control valve 3 communicates with the first working port 32, and the outlet 33 communicates with the second working port 34. The high-temperature and high-pressure refrigerant enters the first heat exchanger 4 through the compressor 2 to be condensed through the control valve 3, then enters the second heat exchanger 6 to be evaporated after being supercooled through the throttling part 5, at the moment, the refrigerant is in a low-pressure and low-temperature state, the refrigerant is divided into two paths, the first path enters the gas-liquid separator 1 through the second working port 34 and the outlet 33, then enters the air suction side of the compressor, and is compressed and discharged by the compressor; the second path enters the third heat exchanger 8 through the first port 81 of the third heat exchanger 8 to cool the temperature of the electric element assembly 7, and then enters the second working port 34 through the second port 802 of the third heat exchanger 8 and the flow regulating part 9 to be combined with the first path refrigerant and enter the second working port 34.
When the refrigerant circulation system is in a refrigeration mode, heat dissipation is large in the working state of components, and the temperature of the electric element assembly 7 is high.

If the adjusting part is in a non-0 state, the opening degree of the throttling part is adjusted by increasing delta 1, and after the operation is carried out for t time, whether Td falls into a safety range is detected. When Td < tdx, the opening degree of the throttle member is adjusted with a decreasing amplitude of Δδ2, and after the operation time t, it is detected whether Td falls within a safe range. This is cycled until Td remains within the safe range.

The refrigerant with high temperature and high pressure is divided into two paths after entering the second working port 34 through the compressor 2, the first path enters the second heat exchanger 6 for condensation, then enters the first heat exchanger 4 for evaporation through the throttling part 5 from the other end of the second heat exchanger 6, returns to the gas-liquid separator 1 through the first working port 32 and the outlet 33, enters the air suction side of the compressor, and is compressed and discharged by the compressor; the second path enters the third heat exchanger 8 through the flow regulating part 9 and the second port 82 of the third heat exchanger, heats the internal temperature of the electric appliance element assembly, and then enters the second heat exchanger 6 through the first port 81 of the third heat exchanger 8 and the first path of refrigerant.
When the refrigerant circulation system is in the heating mode, the temperature of the electric element assembly 7 is too low due to low outdoor environment temperature, and the third heat exchanger 8 needs to be started for adjustment. When Td is smaller than tdx, the opening degree of the throttling adjusting part 9 is in a 0 state, initialization adjustment is needed, the throttling part is opened to be adjusted to an initial opening degree delta h, and after the operation time t, whether the Td falls into a safety range is detected; if the adjusting member is in a non-0 state, the opening degree of the throttle member is adjusted by an increase in Δδ1, and after the operation time t, it is detected whether td falls within a safety range. When td > tds, the opening degree of the throttle member is adjusted in a decreasing width of Δδ2, and after the operation time t, it is detected whether td falls within the safety range. This is cycled until td remains within the safe range.

3. A flow rate adjusting member 9 is provided between the control valve 3 and the third heat exchanger 8 provided in correspondence with the electric component assembly 7. In the refrigerating mode, the refrigerant for cooling the temperature of the electric element assembly passes through the inside of the electric element assembly and then passes through the flow regulating component, so that not only can the heat exchange amount be regulated, but also the condensation caused by throttling at low temperature can be avoided in the refrigerating mode; in the heating mode, the refrigerant for heating the temperature of the electric appliance component assembly is throttled and cooled through the flow regulating component, so that the heat exchange quantity can be regulated, and the condition that the temperature in the heat exchanger is too high due to high exhaust temperature can be avoided.
