A reduction system for operation cost of chiller adaptive district cooling

摘要

The present invention relates to an absorption refrigerator for generating cold water by receiving a heat source from a district heating heat source, a cooling water circulation line connected to the absorption type refrigerator, a cooling water pump disposed on the cooling water circulation line to pressurize cooling water, and cold water generated from the absorption type refrigerator a cold water circulation line for supplying a cooling load to the cooling load side, a cold water pump disposed on the cold water circulation line to pump the cold water, a temperature sensor for detecting a change in the temperature of the cold water, and the temperature information of the cold water detected by the temperature sensor. to provide a system for reducing operating costs of a refrigerator applicable to district cooling, including a control unit for controlling the supply amount of the cooling water pump, the cold water pump, and the heat source.
