Control strategy for air conditioning chilled water pump frequency conversion based on active regulation of cooling capacity at the terminal

Considers that there are shortages in three kinds of control strategies for conventional air conditioning chilled water variable flow system. Puts forward a control strategy for speed regulation of the variable flow pump that the statistical value of open degree instruction signal of the temperature control regulation valve is used for flow control. Emphasizes that the key of air conditioning chilled water flow regulation is active regulation of cooling capacity at the terminal. It is desirable that the reasonable cooling load needs of all the users in the air conditioning chilled water system can be met while transport energy loss is possibly less.
