地下水源水环热泵空调系统的节能运行研究

根据笔者提出的共用空调动力设备和末端空调水源热泵机组耗电量的推算方法,对北京某公寓地下水源水环热泵空调系统两年多的实测数据进行了分析研究.结果表明,原有系统的二次循环水泵系统能耗大、部分负荷调节性差.对水泵系统进行了节能改造,在原有的定流量二次循环泵上增设变频器.改造后二次循环水泵的节电效率高达35%,节能效果十分显著.

Energy efficient operation of underground water-source & water loop heat pump air conditioning systems

Analyses more than two years field-test data of the underground water-source & water loop heat pump air conditioning system applied to an apartment in Beijing based on the computative method of calculating the electricity consumption of public-used air conditioning driven equipment and terminal heat pump units by the authors. The results show that the secondary circulating pump system of the original system consumes a lot of energy and its control performance is poor under partial load. Puts forward a scheme of energy efficiency innovation by adding a frequency converter to the original constant flow secondary circulating pump. The reformation effect is notable and the rate of power saving is over 35%.
