摘要: An air-conditioning apparatus includes a fan configured to deliver air toward the outdoor heat exchanger, a power unit configured to supply electric power to the fan, a fan input detector configured to detect a physical value related to the electric power supplied to the fan, and a controller configured to control the four-way valve to switch between a first operation in which the outdoor heat exchanger functions as an evaporator and a second operation in which the outdoor heat exchanger functions as a condenser. The first operation is switched to the second operation when the physical value detected by the fan input detector is equal to or larger than a reference value. The controller adjusts the reference value so that the reference value when refrigerant flowing through the outdoor heat exchanger has a high temperature is smaller than the reference value when the refrigerant has a low temperature.

摘要: A plate heat exchanger can reduce thermal contact between a second fluid (water and a third fluid (low-temperature, low-pressure two-phase refrigerant) to enhance thermal efficiency. A plate heat exchanger (1b) includes a heat transfer plate group (102a) that performs heat exchange between a first fluid of high-temperature, high-pressure gas refrigerant and a second fluid of a heating target fluid; and a heat transfer plate group (102b) that performs heat exchange between a first fluid of low-temperature, high-pressure liquid refrigerant and a third fluid of low-temperature, low-pressure two-phase liquid refrigerant. The heat transfer plate group (102a) forms refrigerant channels including a stack of plates, has a configuration that a flow of the first fluid of high-temperature, high-pressure gas refrigerant and a flow of the second fluid are alternately aligned in the refrigerant channels, and causes the second fluid to flow in the outermost refrigerant channel.

摘要: An air-conditioning-apparatus outdoor unit includes a casing, an air-sending device chamber, a machine chamber, a partition, a heat exchanger cover, and an electric box including a bottom plate that defines a bottom surface of the electric box and that is joined to an upper end of the heat exchanger cover. The casing includes a shell panel having an outdoor-air inlet that is open. The heat exchanger cover is positioned to face the outdoor-air inlet, and defines, together with the partition and the shell panel, an air passage communicating with the outdoor-air inlet in the machine chamber. The bottom plate of the electric box has a bottom opening communicating with the air passage.

摘要: A plate heat exchanger includes a plate stack including a plurality of heat transfer plates stacked with each other. Each of the heat transfer plates includes a heat medium inflow hole serving as an inlet for a heat medium, a heat medium outflow hole serving as an outlet for the heat medium, a refrigerant inflow hole serving as an inlet for refrigerant, and a refrigerant outflow portion located below the refrigerant inflow hole and serving as an outlet for the refrigerant. The heat transfer plates define heat medium passages, through each of which the heat medium flowing from the heat medium inflow hole flows, and refrigerant passages, through each of which the refrigerant flowing from the refrigerant inflow hole flows downward, arranged alternately with one another. Each of the heat medium passages and the refrigerant passages is defined between adjacent ones of the heat transfer plates.

摘要: It is an object to prevent a liquid refrigerant from being drawn into a compressor. A heat pump apparatus includes a refrigerant circuit in which a refrigerant circulates, and which is configured by sequentially connecting a compressor, a first heat exchanger, an expansion valve, a second heat exchanger, and a third heat exchanger, and connecting a bypass flow path bypassing the third heat exchanger between the second heat exchanger and the compressor. The heat pump apparatus also includes a water circuit in which water circulates, and which is configured by sequentially connecting the third heat exchanger, the first heat exchanger, and a tank. In the heat pump apparatus, if there is a risk of the liquid refrigerant being drawn into the compressor, a three-way valve is controlled such that the refrigerant flows through the third heat exchanger to be heated by water and evaporated.
