In this paper, variable primary flow chilled water system was selected as the object. The models of cold water chiller and water pump have been built considering the outlet water temperature and partial load operation. Then taking temperature control as load control strategy, indoor temperature, load rate and energy consumption have been studied under different temperature set point. The results show that with the indoor temperature set point increasing to 28℃ from 22℃, the running time at full load all day reduced by 79.6%, power also reduced by about 14.5%. In addition, from the calculation principle of the integrated part load value, the corresponding calculation formula for 24 hours has been given. Furthermore, daily integrated part load value has been put forward to describe the daily power. Key words: air conditioning system, load rate, temperature control, power consumption, integrated part load value 1 引言 随着人们对舒适度要求的
