In order to conserve energy consumed by heat source equipments for air-conditioning, chillers, cooling/chilled water pumps and cooling tower fans are increasingly equipped with inverter to improve their energy efficiency in recent years. But the optimal operation for such heat source system is not established. Two methods are proposed to optimize cooling water temperature control, such as keeping temperature difference constant by controlling water flow rate, keeping the inlet water temperature constant by controlling the rotation of cooling tower fan, etc, but they are not confirmed to be optimal or not. In this research, the optimal operation of chiller system is studied as follows: 1)the development and verification of simulation model, 2)the comparison to ideal optimal operation, 3)discussion of CT selection in design period.
