This unique cooling technology from Freus should not be confused with a swamp cooler. Although water is used to support the cooling, it is sprayed over condensing coils rather than pads.
The water-cooled condensing unit is a residential application of 250 tonnes of split system chillers already commercial buildings. Think of this technology as a mini-cooler for private purposes.
Evaporative water cooler units for split system air conditioners have a number ofAdvantages over air-cooled equipment. Water removes heat from the condenser coils far more efficiently than air. This reduces the temperature of the compressed refrigerant R-22, which in turn reduces the workload of the scroll compressor. Not only that, the compressor last much longer, there is only a minimal loss of cooling when the outside temperature over 100 degrees.
Typical air cooled units can lose up to 25% of their efficiency, whileTemperature.
How much can you save with a water cooled condensing unit?
Charles Mullin, a casino worker who lives in North Las Vegas is also single. So every utility bill comes from his lone paycheck. That's why he turned on the air conditioner to be 1500-square-foot home on a water-cooled condensing unit.
"Before I installed it, I had set my thermostat at 75 to 78 degrees to try to keep my electricity bill down," he said. "I tested the new system with 65Degrees - felt like a meat locker. My bill came to $ 86. This represents about a 45-percent savings and the house was to be cooler. "
Mullin told all his friends to the units and the savings he has seen. He reckoned the Freus system will pay for itself in about two years.
Richard Waite, president of Hal Mechanical, installer of water-cooled AC Mr. Mullin said, they are specifically made for the desert climate.
"The only extra that needed to swap an old air conditioner'sUnit for a new water-cooled to a water line to run it. The device has an automated system, similar to a cistern to hold water in the correct capacity. The system flushes also to avoid calcium build-up. "
The performance is almost constant, varying the capacitor size is not necessary due to the climatic zones, such as air-cooled equipment. The Freus is in the same way as an air-mounted capacitor and has the unique ability to service multiple air handlers. Thisoffers the space saving convenience of housing two or three compressors (up to 10 tonnes in total) in a single housing.
Jim Kilby of Green Valley, a casino management professor, replaced his 10-year-old air conditioners, a 5-ton and a 3-ton, with two water-cooled ones of roughly the same capacity. He expects his electricity bill dropped by one third.
"The hotels have been using this technology for years," said Kilby. "If you think about it, that water is a better job of coolingthe air than air. It just makes sense. "
Whether you evaporative water coolers or water cooled condensing units mentioned, the mini version of the 250 ton chiller is sure to revolutionize the desert cooling.
