The compressor 7 compresses the refrigerant to a high-temperature and high-pressure state, enters the fourth heat exchanger 12 through the four-way reversing valve 8 and condenses to release heat. Then, the refrigerant enters the expansion valve 15 and expands to a low-temperature and low-pressure state.
