In order to study the effects of refrigerant charge on the performance of a small-sized heat pump water heater, many experiments under different charge were carried out. 为了研究制冷剂充注量对小型空气源热泵热水器性能的影响,进行了不同充注量实验。
Calculation of Electric Charge of Residential Quarters in Cities This kind of heater can shift electricity from peak periods to off peak periods, thus it can increase the using time of generators. 城市居民住宅及小区用电负荷计算因此该蓄热电暖器可以实现电网用电负荷削峰填谷,提高发电设备利用率;
