HEAT PUMP TYPE WATER HEATER

摘要

PROBLEM TO BE SOLVED: To provide a heat pump type water heater, including a heat exchanger for refrigerant to water, reducing radiation loss and having high heat exchange efficiency.

SOLUTION: The heat exchanger for refrigerant to water is composed of a first heat exchange pipe 2 in which water flows and a second heat exchange pipe 4 in which refrigerant flows. The periphery and the gap of the heat exchanger 5 for refrigerant to water are surrounded with urethane resin 15 to be completely intercepted from the atmosphere, whereby radiation from the heat exchanger 5 for refrigerant to water to the outside can be remarkably reduced.
