Abstract
Chilling units are driven all year round in industrial plants that have clean rooms and buildings that have data centers, because the inside cooling load of these institutions is large. An earlier report reported that we developed an optimizing control system of free cooling system with open cooling tower and heat exchanger. In this report, cooling water module that is able to produce the chilling water and the cooling condenser water was proposed. After setting up the test equipment, cooling capacity was examined. It was found that the cooling capacity of chiller operation is higher than the free cooling operation.
