ABSTRACT:
This invention is directed to systems, apparatuses and methods for reducing the temperature of a condenser fluid, used in a condenser in an air conditioning system to cool a compressed refrigerant, without releasing fluids to the environment. These systems include a first heat exchanger for reducing the temperature of a condenser fluid using a coolant fluid, a second heat exchanger for reducing the temperature of the coolant fluid using a refrigerant and a cooling system for reducing the temperature of the refrigerant. Theses systems do not release fluids into the environment, which is common when conventional evaporative cooling towers are used to reduce the temperature of condenser fluids.
