Research on Control Method for Variable Flow System of Primary Pump
In the heating,ventilation and air conditioning system of the building,the reasonable design and effi-cient operation are the key to solving the energy consumption of air conditioning.However,in the actual operation of the variable flow water system of the central air conditioning pump,the pump often can not be frequently converted according to the design requirements,so it can not achieve the ideal energy-saving effect.The paper studies the change of pipe network characteristics and resistance coefficient under partial load of variable flow system of prima-ry pump,and adopts qualitative analysis method to analyze the principle,characteristics,limitations and application scope of four control methods,including natural temperature drop method,temperature difference control method,pressure difference control method and minimum resistance method,in order to guide the selection of a reasonable control methods during the operation process of water pump.Thus,the energy-saving operation of air-conditioning water system can be realized.
