The heating, ventilation and air conditioning system is a dual loop heating exchanging system, involving the exchange of building heat in the chiller/condenser unit and the exchange of chiller/condenser heat in the cooling tower. Unlike the chiller/condenser, the water loop between the unit and the cooling tower is not close, allowing the buildup of biofilms in the circulation loop, thereby increasing its insulation and operating cost. This project seeks to test the use ozonation in the circulation loop for controlling biofilm formation on the copper walls of the circulation loop.
