摘要： An air-conditioning apparatus controls that a discharge temperature does not become too high with a refrigerant whose compressor discharge temperature readily rises, and thus suppress degradation of the refrigerant and a refrigerating machine oil. An injection pipe that injects a heat source side refrigerant into a compressor is installed, connected a pipe between a backflow prevention device and an opening and closing device installed on a branching pipe, and an aperture unit in the compressor.

摘要： A heat pump capable of operating in a high COP state even if influx temperature of a medium to be heated flowing into the radiators has increased. The heat pump includes a compressor, a first radiator, a second radiator, an expansion valve, and an evaporator sequentially connected by refrigerant piping to form a first refrigeration cycle, in which a first refrigerant circulates in the first refrigeration cycle, and in which the first radiator and the second radiator are serially connected. A first heat exchange unit that heats the first refrigerant is provided in a refrigerant piping at a refrigerant inlet side of the second radiator, and a second heat exchange unit that cools the first refrigerant is provided in a refrigerant piping at a refrigerant outlet side of the second radiator.

摘要： A plurality of heat transfer fins are arranged so as to surround straight pipe portions of heat transfer tubes connected through bends in a serpentine arrangement. Heat transfer surfaces for transferring heat between air of the heat transfer tubes and the heat transfer fins have holes each having a radius smaller than the critical radius of a nucleus that occurs upon phase change from water vapor to condensed water droplets such that the holes are filled with the air at all times. Water is allowed to move from the holes filled with the air having low surface energy to metal part having high surface energy, thus improving drainage.

摘要： A refrigeration cycle apparatus includes a refrigerant circuit of a refrigeration cycle through which a refrigerant that transits in a supercritical state is allowed to flow, and a flow dividing device that divides the flow of a high-pressure liquid refrigerant in a subcritical state into two or more parts. The flow dividing device is configured such that the device is oriented substantially in the horizontal direction or substantially upward in the vertical direction relative to the direction of flow of the refrigerant in a liquid state. With such a configuration, the flow of refrigerating machine oil is equally divided, thus offering high energy saving while keeping heat-medium conveyance power at a low level without reducing the heat exchanging performance.
