摘要
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。
Develops a complex chilled and hot water unit combining air-source heat pump, solar water heater and electric water heater. According to geographic and meteorological conditions, one economized scheme could be selected from 11 modes for air conditioning, heating and hot water supplying. Presents its constitution and principle. The unit could decrease heat transfer steps and melting frost frequence, and store sensible heat of circulating water. The unit has higher heat collecting efficiency for solar energy and higher system heating efficiency. The first costs and operating costs are lower than those of an air-source heat pump, a solar collector and an electric water heater.
