Given the diversity of climates with useful cool-season sun, climate-responsiveness in thermal mass design might be expected; however, rules developed in the dry, sunny American Southwest dominate teaching and practice throughout the country.
Accordingly, the maximum daily useful cooling produced was 266.8 kJ/m2 of collector area.
In order to demonstrate the potential of magnetic refrigeration to provide useful cooling near room temperature, Astronautics Corporation of America constructed a rotary magnetic refrigerator (RMR) in 2001.
Waste heat is recovered with heat exchangers to generate useful heating in the winter period, while in the summer period an integrated double-effect absorption chiller converts waste heat to useful cooling.
The absorption chiller operated with a daily average coefficient of performance of 1.1 1.25, where the solar energy represented the 75% of generator's total heat input, and the solar cooling ratio (quotient between useful cooling and insolation incident on the solar field) was 0.44.
It's just that, on each, we feel we get something useful or cool in return.
The minivan, automakers would like you to think, can be useful and cool.
Yelp lets you review the reviews — as funny, useful or cool — suggesting that these reviews should be construed in part as style exercises.
"Useful is cool, so we've always tried to be useful to drivers on the road," Mr. Byrne says, and research among "drivers on the West Coast, especially Southern California," identified that horn-honking was "a rampant, out-of-control thing".
Therefore the present NPs quite useful for cool LEDs.
He admitted on an earnings call that Facebook is losing steam with teens, but that he's more concerned with Facebook being useful than cool.
