摘　　要：为减少家用空调器的冷凝热排放量,减少制取家庭生活热水的能源消耗,提出一种将空调器与热虹吸管热水器相结合的系统。在阐述系统原理及运行模式的基础上,对热虹吸管热水器的使用效益和经济性进行了计算,并与电加热、燃气、太阳能、空气能热泵等家庭热水供应方式进行了比较分析。热虹吸管热水器的供热水量和加热速度能够满足家庭每日生活热水需求,替代传统的电热水器或燃气热水器,其相对投资回报年限分别为1.1年和6.9年。A system of domestic air conditioner combined with a thermosyphon water heater was proposed for reducing the energy consumption of hot water heating. The working principle and operation modes of the combined system were presented. Compared with an electric water heater, a gas water heater,a solar water heater and an air source heat pump water heater respectively, the economic efficiency of a thermosyphon water heater was analyzed. The results indicate a thermosyphon water heater could meet the needs of domestic hot water supply. The relative payback periods for replacing an electric water heater and a gas water heater are 1.1 years and 6.9 years, respectively.
