冷库节能主要是节电,据统计,冷库制冷动力设备所消耗的电能约占冷库运行总能耗的95%以上。因此,冷库节电除了要合理选配电动机之外,提高冷库用电功率因数是一条重要途径。目前冷库企业普遍采用静电电容器低压集中成组补偿节电技术,据了解,冷库采用的电容补偿装置及其投切方 Cold storage energy saving is mainly energy-saving, according to statistics, cold storage cooling power equipment consumption of electricity accounted for about 95% of the total energy consumption of cold storage operation. Therefore, in addition to cold storage economize on reasonable motor matching outside, to improve cold power factor is an important way. At present, cold storage companies generally use low-voltage electrostatic capacitors concentrated group of compensation power-saving technology, it is understood that the cold storage capacitor compensation device used and the cut side
