    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: An outdoor unit for a refrigeration cycle apparatus includes a casing, an air-sending device configured to generate an airflow, and an electric component box disposed above the air-sending device, and including a bottom plate on which control components are placed. The bottom plate of the electric component box includes an inclined portion on which a first component among the control components is placed and inclined such that an upstream end of the inclined portion in the airflow is positioned above a downstream end of the inclined portion in the airflow. The bottom plate further includes a horizontal portion on which a second component among the control components is placed horizontally extending downstream in the airflow, and having an upstream end in the airflow that is connected to the downstream end of the inclined portion in the airflow.

    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.
