A two pass heat exchanger is provided. The first pass includes a plurality of tubes located in liquid refrigerant, when employed as an evaporator, whereby the liquid refrigerant draws heat from the water flowing through the tubes causing the water to be cooled and the liquid refrigerant to evaporate. The second pass is a single pipe which need not be located in the liquid refrigerant. The two pass heat exchanger can also be used as a condenser.
