Energy Saving Analysis of Variable Primary Flow System with Screw Chiller

Authors: Yung-Chung Chang, Pin-Cheng Chieng, Jyun-Ting Lu, Tien-Shun Chan, Ching-Liang Chen, Cheng-Wen Lee

This paper focuses on energy-saving operation and use of the variable primary flow (VPF) of a central air-conditioning system chiller, by means of regression analysis to determine the relationship equation of chiller power consumption and cooled water flow rate, cooled water supply temperature, cooling water return temperature, and partial load, and the relationship equation of the cooled water pump power consumption and the cooled water flow rate. Take the relationship equations as basis to identify the power consumption change curve of loads in different flow rates, and calculate the most energy-saving cooled water flow rate of the chiller and the cooled water pump in various loads.
