PURPOSE: An air conditioning apparatus using a hybrid heat pump is provided to improve air conditioning efficiency by preventing problems resulting from the reduction of outdoor temperature. CONSTITUTION: An air conditioning apparatus comprises a compressor(10), high-temperature heat exchangers(20a,20b), a condenser(30), an expansion valve(40), an evaporator(50), a refrigerant circulation pipe, an outdoor unit(70), a resonator(80), and a thermal medium circulation pipe(90). The expansion valve is connected to the condenser and expands the refrigerant passing through the condenser. The evaporator evaporates the refrigerant expanded by the expansion valve through heat exchange with a thermal medium and supplies it to the compressor. The refrigerant circulation pipe connects the compressor, the high-temperature heat exchangers, the condenser, the expansion valve, and the evaporator. The outdoor unit cools the thermal medium flowing through an outdoor heat exchanger in a heating operation and heats the thermal medium in a cooling operation. |
