Global Cooling The History Of Air Conditioning - ASME > 자유게시판

The first modern air conditioner was invented in 1902 by Willis Haviland Service, a skilled engineer who began experimenting with the laws of humidity control to unravel an application downside at a printing plant in Brooklyn, NY. Borrowing from the ideas of mechanical refrigeration established in earlier years, Carrier’s system despatched air by means of coils stuffed with chilly water, cooling the air while at the identical time removing moisture to regulate room humidity. In 1933, the Service Air Conditioning Firm of America developed an air conditioner using a belt-driven condensing unit and related blower, mechanical controls, and evaporator coil, and this device became the model in the growing U.S. marketplace stabilizer for phone camera air-cooling systems.

The design of air-conditioning techniques takes many circumstances into consideration. A self-contained unit, described above, serves an area immediately. Extra advanced systems, as in tall buildings, use ducts to deliver cooled air. Within the induction system, air is cooled once at a central plant and then conveyed to individual items, the place water is used to adjust the air temperature according to such variables as sunlight exposure and shade. In the twin-duct system, warm air and cool air journey by way of separate ducts and are blended to reach a desired temperature. A simpler approach to manage temperature is to regulate the amount of cold air provided, chopping it off once a desired temperature is reached. This method, known as variable air volume, is widely utilized in both high-rise and low-rise commercial or institutional buildings.

Editor's observe: In case your customer needs you to design a neighborhood space community, there are quite a few tasks to pursue -- working by means of a networking hierarchy that extends from the access layer to the core, determining what subnet mask to use and, normally, studying the client's networking requirements. This network design checklist provides tips about how to construct a local area network. So, draw up these community diagrams and get to work.
