Abstract
A cooling system of the type having a cooler section. The conventional cooling tower is disconnected and replaced by a cooling loop connected to a water source such as a municipal water supply, irrigation system or gray water system which cools the condenser portion of the cooler. Isolating heat exchangers may be interposed in the cooling loop to avoid contamination. A by-pass system and tempering valve maintain the water supply at a predetermined temperature. Heat may be extracted from the water return and utilized at a remote location as for heating a part of a building while another part is being cooled.
Claims7
A method of retrofitting a chiller system of the type having a condenser, cooler, compressor interconnected and operating on a vapor compression cycle and in which cooling water is supplied to the condenser and returned to a cooling tower, said method comprising:
- (a) disconnecting the cooling water supply to the condenser from said cooling tower;
- and
- (b) re-connecting said condenser to a cooling water supply from an existing in-place water supply dedicated for another use whereby cooling water is supplied to the condenser and returned to the water supply.
