Opmization of Energy Consumption in Chilled Plant
摘要
Abstract
In order to optimize energy consumption of chilled plant, a energy consumption model of chilled plant was established by a way of system identification. Part load ratio 、cooling water inlet temperature.,chilled water flow and cooling water flow was involved in the model. By data processing, as variable flow of cooling water and chilled water operated, COP value of chiller was a bit reduced with the lower water flow, but due to the large scale decreased pump consumption,the total energy consumption was reduced. The power of chilled water and cooling water pumps was about 20% of total power in the chilled plant mentioned in the paper. The energy saving ratio was 5% ~ 14% after optimization of the chilled plant,when part load ratio is in the range of 50% ~90% ,the inlet temperature of cooling water is in the range of 23～31℃. Larger the pump consumption was, greater the energy saving ratio.关键词
