AIR CONDITIONING HEAT SOURCE SYSTEM AND CONTROLLING METHOD OF THE AIR CONDITIONING HEAT SOURCE SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide an air conditioning heat source system capable of increasing energy saving effect, and simultaneously conducting variable water amount control and variable supply water temperature control. SOLUTION: This control device 1 comprises at least a heat source apparatus energy calculating portion 1a, a pump energy calculating portion 1b, and a minimum value computing portion 1c. The minimum value computing portion 1c calculates the energy consumption amount Psystemof the air conditioning heat source system from the energy consumption amount Pchillerof a chiller calculated by the heat source apparatus energy calculating portion 1a, and the energy consumption amount Ppumpof a secondary pump calculated by the pump energy calculating portion 1b, and calculates supply water temperature Tswith which the energy consumption amount Psystemof the air conditioning heat source is minimized.
