Abstract
An air-conditioning system for a cooling operation and a heating operation comprises a first heat exchanger to which a high-pressure and high-temperature refrigerant which has not been substantially cooled and adiabatically expanded after being compressed is supplied to heat the inside of a room to be air-conditioned during both of the cooling operation and the heating operation, a second heat exchanger to which a low-pressure and low-temperature refrigerant which has been substantially cooled and adiabatically expanded after being compressed is supplied to cool the inside of the room during both of the cooling operation and heating operation, and an air flow generator for generating an air flow which passes the first heat exchanger and the second heat exchanger, wherein the second heat exchanger is arranged at an upstream side of the first heat exchanger in the air flow.
