Study of water-source heat pump unit under variable ground water flow rate conditions

 Studies the operating performance of water-source heat pump for different loads and  ground water pump power consumption with variable frequency, obtains the variable flow rate operating characteristics of the water-source heat pump system. Finds out the best partial load coefficient performance at some ground water flow rate proportion and presents an operating scheme. The running costs and ground water quantity will be saved by using variable ground water flow control, and initial investment can be recovered within one year.
