摘要
热泵热水器借助外部能量能把不能直接利用的低位热源转换为可以利用的高位热能,从而达到节约部分高位能的目的。阐述了热泵热水器的发展历史与应用现状,分析了空气源热泵的工作原理和节能原理,并将空气源热泵热水机组与电热水器、燃油热水锅炉、燃气热水锅炉等热水供应系统的性能进行了比较。在此基础上,结合企业工程应用实例,指出了推广热泵技术对于节能减排的意义。
By means of external energy,low-geade thermal energy can be converted to high-grade thermal energy by a heat-pump water heater and it is thus an energy-saving installation.In this paper,the history,development and status-quo of application of heat pumps were summarized,and the working principle and energy conservation effects of air source heat pumps were analyzed.A performance comparison of air source heat pump water heaters with the conventional hot-water supply installation was carried out,including electric water heaters,oil-fired and gas-fired hot water boilers.It was therefore concluded that wider application of air source heat pumps is quite important for energy conservation and environmental protection.
