摘要： 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.

摘要： A heat exchanger includes a plurality of fluid passages through which a heat-exchanger fluid including a liquid-phase fluid passes, a tank disposed above inlet parts of the fluid passages for distributing a flow of the heat-exchanger fluid to the fluid passages, and a retention member that is located above the inlet parts within the tank, for temporarily storing therein the liquid-phase fluid flowing into the tank. The retention member is constructed such that the liquid-phase fluid overflowing from the retention member falls toward the inlet part. Accordingly, the heat-exchanger fluid can be uniformly distributed into the fluid passages from the tank. For example, the heat exchanger can be used as an evaporator for a refrigerant cycle device having an ejector.
