    摘要： It is aimed to provide a heat pump type hot-water supply outdoor apparatus that can control a temperature of a compressor shell, according to a water temperature of a water circuit and a temperature of the compressor. A heat pump type hot-water supply outdoor apparatus 1a includes a refrigeration cycle including a compressor 2, a water-refrigerant heat exchanger 3, an expansion valve 4, and an air heat exchanger 5, a water jacket 10 that is arranged on the shell of the compressor 2 and connected in the middle of a branch water circuit 8 branching in parallel to a main water circuit 7 which starts from a hot water storage tank 30 and returns to the hot water storage tank 30 through a water-refrigerant heat exchanger 3, a water flow valve 9 that is connected between a branch A and the water jacket 10 and regulates the quantity of water flow, according to a control signal, a shell temperature detection sensor 6 that senses a temperature of the shell of the compressor 2, a water temperature sensor 11 that is installed in the vicinity of the branch A and senses a temperature of the water flowing out of the hot water storage tank 30, and a control apparatus 20a that generates a control signal for controlling the water flow valve 9, based on the temperature sensed by the shell temperature detection sensor 6 and the temperature sensed by the water temperature sensor 11, and outputs it to the water flow valve 9.

    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 (1) 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. The heat transfer plate group (102b) forms refrigerant channels including a stack of plates, has a configuration that a flow of a the first fluid of low-temperature, high-pressure liquid refrigerant and a flow of the third fluid are alternately aligned in the refrigerant channels, and causes the first fluid of low-temperature, high-pressure liquid refrigerant flows in the refrigerant channel adjacent to the heat transfer plate group (102a).
