Abstract：
Presents the indirect control scheme of variable flow rate, i.e. regulating the temperature of hot water of heat recovery by regulating the water flow rate in ground side to safeguard the steady temperature of chilled water and heat recovery water. Presents the control principle and scheme. With an example project in Hangzhou, verifies the control accuracy of the system, and the result shows that the control effect is favorable.
