Air blast and induced draft fans in two ways. ① Air: air flows through the fan back into bundles. ② blower type: after the air flow through the tube into the fan. Former operations less economic, resulting in turbulence on heat transfer of beneficial, use more. The latter uniform air flow distribution, conducive to accurate control of temperature, noise, is the direction of development. Thermal fluid exports mainly rely on regulation of temperature control by air flow Tube bundle, adjust the angle of the blade, the fan speed and degree of opening shutters. Yi Ning, easy to freeze during the winter of fluids, hot air circulation method or the steam is used to regulate fluid outlet temperature.

1; with as cold ambient air carrier, used for cooling a high temperature of medium (such as hot water from high oil), medium temperature decrease, to reach the intended process requirements, can be called the air cooler, referred to as "air cooling". 2, with a cold medium can be vectors (such as cooling water; water; freon), to cool the air, reducing the temperature of the air to the booking process requirements, also known as an air cooler.

In world economic recession of situation Xia, many China enterprise in for mass of transformation, from traditional market development transformation to Internet network development, in comparison single B2B platform in the select more of promotion way, many jaw crusher and grinding-mill manufacturers enterprise in industry competition very fierce of situation Xia, select has more platform and more website of promotion mode to for promotion publicity, made has very good of effect.
Printing industry is the same, some string tag and hang tag under the situation of dealers in the global market is in the doldrums, more precise market targeting, such as in the United States jewelry cards and the price tag the market is very good, but also to the survival of many foreign trade companies and many opportunities.
But the wedding dresses are not the same, traditional wedding there is no brand leading product promotion manufacturing is very difficult, but some of the big brand companies wedding dress market is very good, such as: wedding dress Anjolique,wedding dress of Bonny which brands are selling very well.
However these industries so fierce competition in the market, there is a market still very stable, it is the tattoo machines , many tattoo supply are wondering why their market is not affected by the global economic shocks

Air cooler can save a lot of water, reduce pollution, protect the environment, reduce infrastructure costs. To expand the air cooler used in the 1960 of the 20th century there was a wet type air cooler, in front of the tube increases sprinklers, use a small amount of spray water on the fin surface evaporation of significantly enhanced heat transfer, heat transfer efficiency than dry-up to 2~4 times. Wet type air cooler has been widely used in refineries. Dry-type air cooler tubes and water-joint-type air cooler air cooled tube bundles. Development of low contact resistance and high heat transfer efficiency of fin-and-tube, low power consumption, low noise fans is key to the development of the air cooler

 

That one necessary thing we need right now to beat the heat.

 

ya, I agree with you friend... But, may be Air Conditioners are better than air coolers... these are no need water...
