摘要 热水器供水洗浴时,大部分热能随着废水的外排而浪费掉了,因而能源利用效率底下,而且热废水外排对环境造成了一定的热污染;尽管热电装置作为制冷系统效率较低,但作为热泵系统,相对于利用电能直接加热的装置其热输出效率却较高;热电热泵快热式热水器,通过回收洗浴废水热能达到了节能、环保的双重目的;卫生热水能耗在民用及各种商业建筑环境能耗结构中的比例日益增大,热电热泵装置为废热利用、建筑环境节能提供了新的思路。 The energy utilization of water heater is very inefficient because a majority of heat energy is squanderedaway with waste water excluding, which brings on 'heat' pollution in environment. Although thermoelectric system hasa low refrigerating efficiency, as a heat pump, it has a high calefaction efficiency in comparison with a electric heatingunit. A thermoelectric heat pump instantaneous water heater can achieve the double goal of energy saving and environ-ment protection by means of recovering the heat energy contained in waste water. The proportion of energy consumptionof hot water is increasing in both of civil and commerce building environment, and thermoelectric heat pump systembrings new ideas on the method of building energy saving and waste energy utilization.
