• • The low-temperature refrigerant absorbs heat from the air through a low-temperature air heat exchanger, which is then compressed to medium temperature by a low-temperature compressor. The heat is then transferred to the high-temperature refrigerant through an intermediate heat exchanger, and then compressed to a high temperature by a high-temperature compressor. Finally, it is heated to 90°C by a high-temperature hot water heat exchanger.
