Now, an AC that can cool with less than half the energy needed by conventional cooling units

Washington, August 16 (ANI): Tests have shown that a new air-conditioner developed by a company in the US can cool a typical big-box store with less than half the energy needed by conventional cooling units.

The five-ton commercial rooftop unit, developed by Coolerado Corp. of Denver, US, was also the first certified winner of the UC (University of California) Davis "Western Cooling Challenge".Coolerado's entry in the Western Cooling Challenge was the first to take our rigorous tests at the Advanced HVAC Lab at the US Department of Energy's National Renewable Energy Laboratory in Golden, Colorado," said Mark Modera, director of the UC Davis Western Cooling Efficiency Center.

"We are extremely pleased to announce that Coolerado's product exceeded our expectations. While our target was a 40 percent reduction in energy use and peak electricity demand compared to conventional cooling units, the Coolerado H-80 tests indicate almost 80 percent energy-use savings and over 60 percent peak-demand reduction," he added.

According to Coolerado CEO Mike Luby, his company's five-ton H-80 rooftop unit is designed principally for light commercial buildings.

One H-80 is able to cool 1,500 to 3,000 square feet of commercial floor area.

"Coolerado would not have taken on the big task of producing this exceptional product had it not been for the challenge laid down by the Western Cooling Efficiency Center," Luby said.

Launched in June 2008, the UC Davis Western Cooling Challenge is a program of activities designed to help cooling-unit manufacturers deliver better products, and to help building wners install and use those products in their new and existing low-rise, nonresidential buildings (such as suburban retail and office buildings).

Increase in air pollution in China over last 50 years reduces rainy days by up to a quarter

Washington, August 16 (ANI): New research shows that air pollution in eastern China has reduced the amount of light rainfall over the past 50 years and decreased by 23 percent the number of days of light rain in the eastern half of the country.Atmospheric scientist Yun Qian at the Department of Energy's Pacific Northwest National Laboratory led the research......

Heating of Arctic current contributes to global warming

Washington, August 16 (ANI): Scientists have found that the warming of the northward-flowing West Spitsbergen current in the Arctic over the last thirty years has contributed to global warming by triggering the release of methane, a potent greenhouse gas, from methane hydrate stored in the sediment beneath the seabed.Methane hydrate is an ice-like substance composed of water and methane, which.....

Keeping nutrients in astronauts' food vital during long space flights

Washington, August 16 (ANI): A new study has determined that keeping nutrients in astronauts' food is vital during long space flights.Maintaining the health of the crew aboard a spacecraft is a critical issue especially during extended trips.Because foods may lose their nutrients during extended space missions, food scientists are analyzing ways to increase shelf life of nutrients in the food......
