Abstract
As we all know, how to achieve better energy savings has been mentioned on various countries' energy schedules. Public buildings as a large energy consumption. It's air conditioning system has a lot of energy-saving space, and air-conditioning chilled water system to optimize energy-saving control is an important measure to achieve energy-saving air-conditioning system initiatives. This paper mainly focuses on the control system of variable frequency pump in chilled water system. For the water pump control strategy, the secondary pump frequency control strategy is discussed, in order to obtain a better control strategy, in detail the current commonly used differential pressure control strategy. In this paper, five kinds of differential pressure control strategies are analyzed, and then the simulation model is simulated by the established mathematical model. The input energy consumption model of the inverter - motor - water pump micro - system is obtained and the simulation results are analyzed.
