AIR CONDITIONING PROCESSES

INTRODUCTION TO AIR-CONDITIONING PROCESSES:

As mentioned earlier, the term “air-conditioning”, when properly used , now means the total control of temperature, moisture, in the air (humidity), supply of outside air for ventilation, filtration of airborne particles , and air movement in the occupied spaces. There are seven main processes required to achieve full air conditioning and they explained below:

The processes are:

1-heating__ the process of adding thermal energy (heat) to the conditioned space for the purposes of raising puroses of raising or maintaining the temperature of the space.

2-cooling__the process of removing thermal energy (heat) from the conditioned space for the purposes of lowering or maintaining the moisture content of the air.

3-humidifying__the process of adding water vapor (moisture)to the air in the conditioned space for the purposes of raising maintaining the moisture the content of the air.

4-dehumidifying__the process fo removing water vapor (moisture) from the air in the conditioned space for the purpose of raising or maintaining the moisture content of the air.

5-cleaning__the process of removing particulates, (dust etc,) and biological contaminants, (insects, pollen etc,)from the air delivered to the conditioned space for the purposes of improving or maintaining the air quantity.

6-ventilation__the process of exchanging air between the outdoors and the conditioned space for the purpose of diluting the gaseous contaminants in the air improving or maintaining air quality, composition and fresh MECHANICAL VENTILATION. Natural ventilation is driven by natural by using fans to draw air in from outside or by fans that exhaust air from the spaces to outside.

7-air movement__the process of circulation and mixing air through conditioned spaces in the building for the purposes of achieving the proper ventilation and facilitating the thermal energy transfer.
