Definition Of Air Conditioning
The American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) defines air conditioning, as: "the process of handling air, so as to control the temperature, humidity, cleanliness and distribution to meet the requirements of the conditioned space.
As the definition indicates important steps involved in the work of air-conditioning:
- Temperature control.
- Humidity control,
- Air filtration, cleaning and cleansing.
- Air movement and circulation.
In winter, heating conditions require automatic control of the heating source to maintain the desired room temperature. Humidity control for use in winter conditions, as a rule, requires the addition of moisture humidifier
Summer cooling conditions require automatic control of the air conditioning system to maintain the desired room temperature. Control of humidity in summer conditions requires dehumidifiers, which undergo cooling air over cold surface of the evaporator.
In General, air filtration is the same in both summer and winter.
Air filtration equipment, as a rule, consists of a very fine porous substances. Air is drawn through them, to remove debris. Filters based on activated carbon filters can be added to ordinary filtering mechanisms for improving air cleaning. Air pollutants, and methods of their removal from the air, will be discussed in subsequent paragraphs.
Many industries have air conditioning plants for two reasons: for the comfort provided and for more complete control of production processes and materials. Better control of temperature and relative humidity improves the quality of the finished product..
