Abstract

A subcool condenser having a condensation heat exchange portion, a receive portion and a supercool heat exchange portion is used as an outdoor heat exchanger that functions as a radiator in a cooling operation mode so that COP in the cooling operation mode is increased. In contrast, in a heating operation mode, a refrigerant bypass device that causes the refrigerant to flow so as to bypass the supercool heat exchange portion is provided so that pressure loss generated in the refrigerant flowing through the outdoor heat exchanger is decreased. Thereby, driving force of a compressor can be decreased and COP in the heating operation mode can be improved.
