    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: An air-conditioning apparatus includes: an outdoor unit including a compressor, a first refrigerant flow path switching device, and a heat-source-side heat exchanger; a heat medium relay unit including an intermediate heat exchanger, an expansion device, a second refrigerant flow path switching device, and a pump; and at least one indoor unit including a use-side heat exchanger. A refrigerant pipe connects the compressor, the first refrigerant flow path switching device, the expansion device, the second refrigerant flow path switching device, and the intermediate heat exchanger, thereby making up a refrigeration cycle. A heat medium pipe connects the intermediate heat exchanger and the use-side heat exchanger, thereby making up a heat medium circulation circuit in which a heat medium different from the refrigerant circulates. The first refrigerant flow path switching device is switched to execute a defrost operation mode.

    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.

    摘要: An outdoor unit is configured to include a compressor and a heat source side heat exchanger. Indoor units are configured to include first expansion devices and use side heat exchangers, and air-condition an air-conditioned space. Branching devices, connected by pipes to the outdoor unit by a plurality of main pipes and connected by pipes to each indoor unit by a plurality of branch pipes, are configured to branch a refrigerant from a side of the main pipes and circulate the refrigerant to the branch pipes, and converge the refrigerant from a side of the branch pipes and circulate the refrigerant to the main pipes. A refrigerant concentration detecting device is installed in a non-air-conditioned space. A shutoff valve control device is configured, upon determining that the refrigerant has leaked, to control shutoff devices and to shut off the refrigerant flows.
