HVAC stands for Heating, Ventilation and Air Conditioning. The objective of HVAC is to control the temperature of air along with control of moisture, filtration of air, etc. In this article we discuss HVAC for beginners and the essentials of comfort zone engineering along with psychometric chart.
Basic Need for HVAC
The objective of HVAC are to control the temperature of air inside the designated “Air Conditioned" space along with control of moisture, filtration of air and containment of air borne particles, supply of outside fresh air for control of oxygen and carbon dioxide levels in the air conditioned space, and finally control of the movement of air or draught. All these factors comprise of a successful HVAC system. Air conditioning has changed over the years from just cooling of a space to the effective control of all the above parameters.
