Commercial and Residential Water Cooled Air Conditioning

All systems have a Seasonal Energy Efficiency Ratio (SEER) rating which is based on an outside temperature of 82°F. On a hot day (95°F and up), air cooled systems rated at 12 on the SEER scale operate below 10 SEER, or, as the temperature rises, even lower. 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.

Compressor Performance Compared to Air Cooled Condensing*

*Based on Copeland Corporation Performance Data for SCROLL Mdl. ZR34K1PFV (3 ton compressor) Standard conditions: 45°F Evaporating Temperature, comparing condensing temperatures of 130°F for an air cooled unit with 90°F for a water cooled system.

Annual Cost Comparison Across the Sunbelt*

*Based on 2,000 annual cooling hours calculated by American Refrigeration Institute for Phoenix, Austin, Mobile, and Jacksonville. Cost: 9.2 center per Kwh (Total marginal rate for Austin). Cooling hours are 50% greater in South Texas and South Florida.
