PROBLEM TO BE SOLVED: To provide a plate heat exchanger for a heat pump, precisely measuring refrigerant temperature in a condensation area or an evaporation area of a refrigerant for the heat pump by a simple means.SOLUTION: A plate heat exchanger HE for a heat pump includes: a plurality of heat exchanger plates 3A, 3B layered in a thickness direction and configured to mutually form refrigerant flow paths 6A and water flow paths 6B of the heat pump between the layered heat exchanger plates; an end plate 4 layered on a side of an outer surface of an outermost heat exchanger plate 3A'; and a temperature sensor 7 for detecting refrigerant temperature. The plate heat exchanger HE for the heat pump is used to condense or evaporate a refrigerant for the heat pump. The outermost flow path is made to serve as the refrigerant flow path 6A. The end plate 4 is provided with a hole 45 passed through the thickness direction. The temperature sensor 7 is inserted from the outside of the end plate 4 into the hole 45, and is thereby brought into contact with the outermost heat exchanger plate 3A'. |
