Air conditioning industry

Our last study takes us away from the plastics industry into an entirely new realm, that of environmental control. Man, through recent decades, has learned how to control the temperature and humidity in confined spaces. Witness the vast growth of the air conditioning industry over the past twenty-five years. Now he has learned how to destroy odors. Why not live in an odor-free atmosphere as well as one of controlled temperature and humidity We can—and the product to accomplish this is known as Purafil—a purple pellet made from activated alumina and potassium perman-... 

This has been the area where CFCs have excelled in their application. The air-conditioning industry owes much of its tremendous growth to the chlorofluorocarbons. The CFCs were judged to be safe alternatives to materials such as sulfur dioxide and ammonia over 70 yr ago and allowed refrigeration to become available safely in houses and automobiles. 

The National Weather Bureau, in 1959 started issuing a Discomfort Index, providing a measure of heat and humidity. The air conditioning industry grew as the index became more popular. 

In reading such a device, we normally read an elevation the actual operational reading in Example 2,14 was 2.5 ft. For many purposes it is convenient to think of pressures and to report them in terms of such manometer reading as heights the U.S. air conditioning industry, for example, commonly refers to all pressure in air conditioning ducts as inches of water, and most U.S. vacuum equipment manufacturers refer to vacuums as inches of mercury. ...

People doing moderate levels of work in non-air-conditioned industrial plants might require as much as a 250-ft/min (1.3-m/s) velocity of air movement in order to be able to continue working as the air temperature approaches 90°F (32°C). This would not necessarily provide a full-comfort condition, but it would provide acceptable relief Loose paper, hair, and other light...
