But, the Thermal Flow System uses a water cooled evaporative condenser to remove heat from the freon.
Air cooled systems use an aluminum finned air cooled condenser to do the same job.
However, with air cooled units, the efficiency of the system is directly related to the outdoor temperature. When it's hot, your need for cooling increases, but the air cooled system loses both capacity and efficiency. The water cooled system loses neither as the temperature rises. In fact, on extremely hot days, the evaporative water cooled unit actually improves in efficiency and capacity. This means smaller motors that use less electric energy.
