To interior heat exchanger assembly, in the car after the heat exchange of heat exchanger assembly, enters back into system and adjust integrating device, through gas-liquid separator
Finally it is back to motor compressor；
2) system hypothermia heating process is as follows: motor compressor enters system through exhaust pipe and adjusts in integrating device, and freeze oil
Refrigeration oil present in exhaust is entered into motor compressor by oil return pipe from device, the end the A end-D of three-position four-way valve is logical at this time, C
The end end-B is logical, and refrigerant adjusts integrating device heat exchanger assembly into the car, in the car heat exchanger assembly heat exchange by system
Afterwards, and be back to system and adjust in integrating device, the end the H end-E of two-position four-way valve is logical at this time, the end the F end-G is logical, adjusted convert into
It enters back into system after vehicle external heat exchanger assembly heat exchange to vehicle external heat exchanger assembly and adjusts integrating device, through gas-liquid separator
Finally it is back to motor compressor；
Under 0 DEG C to -20 DEG C of low temperature condition, secondary expansion valve, which is opened, carries out ftercompction to the middle pressure chamber of motor compressor；
3) system Booting sequence is as follows: when system just starts, motor compressor enters system through exhaust pipe and adjusts integrated dress
In setting, the end A-C-terminal of three-position four-way valve is logical, by refrigerant/oil separator, gas-liquid separator, respectively from oil return pipe oil return, air-breathing
Pipeline returns refrigerant, and refrigerant does not flow in remaining pipeline.
