摘要：
Energy saving has become more and more important in air conditioning system design. The energy-saving effect and feasibility of various control methods of circulation pump in air conditioning systems were analyzed and compared. Both qualitative analysis and numerical calculation show that the temperature difference control has the best energy saving effect, and followed is the minimum resistance control method, and the pressure difference control has the least energy-saving effect. The utilization of the control strategy in engineering design needs a good balance and careful analysis according to the system scale, composing of the load, the balance of the resistance of the water system, and how often of the terminal devices been used.
