Application Discuss Analysis of Water Pumps Frequency Conversion Control in Air Conditioning Systems

Xu Shuhui,Ma Maidun,Wang Juan(School of Environment and Energy Engineering,BUCEA Beijing 100044)  
The energy-saving effect and feasibility of several kinds of variable frequency circulating pump control in air conditioning system were analyzed and compared. Both qualitative analysis and numerical calculation show that the temperature difference control method has the best energy-saving effect,and the second is the minimum resistance control method,and the pressure difference control has the worst energy-saving effect.The utilization of the control method in engineering design needs a good balance and careful analysis according to the system size,composing of the load,the balance of the resistance of the water system,and the frequency of the application of the end equipment.
