To prevent global warming, the refrigerant HFC 134 a currently used in automobile air-conditioners has been slated for eventual elimination. CO2, a natural refrigerant, has attracted attention as an alternative. Evaporator, gas-cooler, intercooler and compressor efficiencies have been improved, and a high-pressure control method has been developed to maximize COP (Coefficient Of Performance) in automobile airconditioning using a supercritical refrigeration cycle with CO2, as the refrigerant. An evaluation of the system verified that these improved components provide COP equal to or better than that of the systems using HFC 134 a.
