HEAT EXCHANGER FOR HOT WATER SUPPLY

摘要

A hot water supply heat exchanger includes a water pipe (1) including a water pipe (W) and a refrigerant pipe (2) forming a refrigerant passage (R) and heats water flowing through the water passage (W) by a refrigerant flowing through the refrigerant passage (R). An inlet part (A) of the water passage (W) including water of a predetermined temperature or less is provided with a heat transfer enhancer. This sharply enhances the performance of the whole heat exchanger.
