A path-breaking technology developed mostly by advancements made in the field of mechanical engineering, HVAC- the standardized acronym for Heating, Ventilation and Air Conditioning, serves to provide thermal comfort and acceptable air quality indoors and in a vehicular environment.
Based on the principles of thermodynamics, heat transfer and fluid mechanics, it constitutes an integral part of all such structures, residential or industrial, where safe and healthy building regulations are regulated so far as temperature, humidity or air quality are concerned. The basic function of HVAC, therefore, is to perform heating and or cooling functions for buildings- residential, commercial or industrial; and provide for the optimum quality of indoor air by regularized air circulation. It should be noted that ‘Refrigeration’ is sometimes added to the abbreviation as HVAC&R or HVACR, and sometimes the ‘Ventilation’ is omitted to make it HCAR. The aforementioned central functions of HVAC, that include heating, ventilation, and air conditioning are interrelated.
This happens especially because of the need to provide thermal comfort and acceptable air quality within a fixed and feasible installation, operation and maintenance cost. The system is thus used to provide ventilation and maintain the room air distribution of buildings. Midlothian HVAC is now an indispensable part of residential structures such as houses, apartments or hotels; industrial organizations and official institutions such as hospitals or offices; and even in ships or submarines, where temperature and air quality needs to be regulated.
