    摘要: An air-conditioning apparatus includes a heat medium circuit that circulates a heat medium different to the refrigerant on a heat source side. The heat medium circuit includes, for example, heat exchangers related to heat medium, use side heat exchangers, first heat medium flow switching devices and second heat medium flow switching devices that change passages of the use side heat exchangers, heat medium flow control devices that controls a heat medium amount in the corresponding use side heat exchangers. An on-off device is each provided on the upstream side of the heat medium flow control device and on the downstream side of the second heat medium flow switching device and a first backflow prevention device is each provided on the downstream side of the heat medium flow control device and on the upstream side of the first heat medium flow switching device.

    摘要: An air-conditioning apparatus includes a controller which calculates a composition ratio of a refrigerant mixture using a high-pressure-side pressure of a refrigerant discharged from a compressor, a low-pressure-side pressure of a refrigerant to be sucked into the compressor, a high-pressure-side temperature of a refrigerant at an inlet side of a second expansion device in a high/low pressure bypass pipe, and a low-pressure-side temperature of a refrigerant at an outlet side of the second expansion device in the high/low pressure bypass pipe and which determines whether to open or close a bypass-channel opening/closing device.

    摘要: A refrigerant circuit device includes a compressor, a heat exchanger that is capable of exchanging heat between the refrigerant and a heat medium, and other components that are connected by pipes, in which the refrigerant circuit circulates a refrigerant. A heat medium circulating circuit circulates the heat medium in the heat exchanger. At least the compressor is housed in an outdoor unit, at least the heat exchanger is housed in a heat medium relay unit, and an indoor unit is housed in a use side heat exchanger. The outdoor unit, the heat medium relay unit, and the indoor unit are formed separately and can be disposed in separate positions. A housing of the heat medium relay unit has an opening that allows ventilation between the housing space of the heat exchanger related to heat medium and the space outside the housing space.
