Abstract: 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.
