Abstract

The purpose of this study is to investigate the application of variable frequency primary pump technology. The energy conservation effect and feasibility of several kinds of variable frequency circulation pump control in air conditioning system were analyzed. The results show that the temperature difference controls has the best energy conservation effect. The utilization of the control method in design needs a good balance and careful analysis according to the system size, composing of the load, and the balance of the resistance of water system.
