Abstract
A combined refrigerating/freezing and air conditioning system is provided. The system may include an air conditioning circuit, a refrigerating circuit, a freezing circuit, a first heat exchanger, and a second heat exchanger. The air conditioning circuit may include a compressor, an outdoor heat exchanger, and an indoor heat exchanger. The refrigerating circuit may include compressor, a condenser, and an evaporator. The freezing circuit may include a compressor, a condenser, and an evaporator. The refrigerant of the air conditioning circuit may be heat-exchanged with the refrigerant of the refrigerating circuit in the first heat exchanger, and the refrigerant of the refrigerating circuit may be heat-exchanged with the refrigerant of the freezing circuit in the second heat exchanger to improve air conditioning efficiency and refrigerating/freezing efficiency of the system.
