1、空气源热泵热水器常见故障及维修 摘要：空气源热泵热水器是继燃气热水器、电热水器和太阳能热水器之后的第四 代热水装置，高热效率是空气源热泵热水器最大的特点和优势。目前大多空气源 热泵热水器制造企业采用家用空调器相同的制造技术制造空气源热泵热水器， 而 空气源热泵热水器较之家用空调器运行工况恶劣， 导致空气源热泵热水器故障率 高，也影响了空气源热泵热水器进一步推广使用。本论文对空气源热泵热水器安 装维修基本方法进行了总结， 对毕业实习期间所遇到的空气源热泵热水器常见制 冷系统、电气控制系统和结构件故障的维修方法进行了分析与总结，希望与同行 交流与分享。 关键词：关键词：空气源热泵热水器；故障；维修
2、 Common errors and maintenance ofCommon errors and maintenance of air source heat pump water heaterair source heat pump water heater AbstractAbstract: : The air source heat pump water heater is the fourth generation of hot water device, following with gas heater, electric heater and solar water heat
3、er. Its greatest characteristic and advantage is its high thermal efficiency. At present, most air source heat pump water heater manufacturing companies adopt the same manufacturing technology of domestic air conditioner to make air source heat pump water heater. And Because the operating conditions
4、 of air source heat pump water heater is poorer comparing with the domestic air conditioner, the fault rate of air source heat pump water heater is much higher that of the domestic air conditioner, which leads to negative influence on the promotion and utilization. This article make summary on installation and maintenance methods of air source heat pump water heater And the maintenance methods of refrigeration system，electrical control system of air source heat pump water heater were analyzed
