Abstract

Abstract: A direct heating water heater coupled with gas and air source heat pump is developed. According to the different environmental temperature and critical temperature, different operation modes are adopted to produce the required hot water in a cascade heating mode, which can significantly improve the utilization rate of the equipment, save the operation energy consumption, and better serve people's life under the background of "double carbon".

Key words: Water heater, Cascade heating, Gas, Air source heat pump

CLC Number:

TS914.25
