[0024] The utility model provides hydrogen energy through a hydrogen storage tank 1, and converts the chemical energy of hydrogen gas released by a hydrogen energy engine 2 into electrical energy, which is transmitted to a power supply cabinet 3, thereby providing power to various electrical devices in the air conditioning system. The utility model connects various components of the air conditioning system to realize the cooling and heating processes of the air conditioning system by circulating the refrigerant from the high-temperature and high-pressure gas generated by the compressor to the evaporator and then returning to the compressor.

During the heating process, the first interface of the four-way reversing valve is connected to the fourth interface, and the second interface is connected to the third interface.

[0025] The utility model circulates the refrigerant during the refrigeration process: after the refrigerant is discharged from the compressor 5, the high-temperature and high-pressure refrigerant enters the condenser 7 through the first interface and the second interface of the four-way reversing valve 4 to be condensed into liquid, the liquid refrigerant enters the liquid reservoir 9 for storage, the refrigerant in the liquid reservoir 9 is dried and filtered through the filter 10, and then enters the evaporator 12 after throttling by the throttle valve 11, evaporates and absorbs heat in the evaporator 12 to become a gas-liquid mixture, and returns to the compressor 5 through the fourth interface and the third interface of the four-way reversing valve 4, completing a refrigerant cycle.

[0026] The utility model circulates the refrigerant during the heating process: after the refrigerant is discharged from the compressor 5, the high-temperature and high-pressure refrigerant enters the evaporator 12 through the first interface and the fourth interface of the four-way reversing valve 4, exchanges heat in the evaporator 12, and enters the condenser 7 for condensation. The condensed refrigerant returns to the compressor 5 through the second interface and the third interface of the four-way reversing valve 4, completing a refrigerant cycle.

The present utility model adds an oil separator to input the separated lubricating oil from the oil return port of the compressor 5 to replenish the lubricating oil, thereby ensuring continuous lubrication of the compressor 5 and reducing the need for lubricating oil replenishment.
