研制了一种集空气源热泵、太阳能热水器和电热水器于一体的冷热水机组,可根据地理和气象条件从11种运行方案中优选节能方案,实现空调、热水供应和供暖;介绍了机组的构成和工作原理。该机组可减少换热环节和融霜次数,利用循环水显热蓄热,太阳能集热效率和系统供热效率较高,初投资和运行费用低于分别采用空气源热泵、太阳能集热器和电热水器的费用。
An air-source heat pump, a solar water heater and an electric water heater are combined to develop an air-conditioner, a hot water supply and a heating system, which can select energy-saving solutions from eleven operating schemes according to the geographical and meteorological conditions. The composition and working principle. The unit can reduce the number of heat exchange sessions and defrost cycles. The use of circulating water sensible heat storage, solar collector efficiency and system heating efficiency higher than the original investment and operating costs were lower than the use of air-source heat pumps, solar collectors and electricity Water heater costs.
