The term HVAC comes from the words heating , ventilation and air conditioning systems that HVAC contractors include for most, if not all, industrial-sized projects they are working on or are planning to work on in their scope of work. The government requires heat, ventilation, and air conditioning systems for all public and private establishments to ensure the safety and comfort of the individuals who will occupy the structure once it is complete. For smaller projects or structures, the main contractors are usually selecting the equipment that should be integrated into the building, while larger establishments will need input from the building services designers and engineers with regard to what type of system and equipment is needed and correct for the structure. In some cases, the manufacturers design and manufacture a particular model specifically to suit the particular structure. check it out for more info.
Heating is a requirement and a necessity for homes , offices, and other establishments for most countries or areas which have colder seasons. This is to the comfort and health of the people who are going to occupy the building. For homes, it is necessary to have a furnace or boiler room while in industrial buildings, a mechanical room that houses the heating system and perhaps all the other systems that the maintenance crew may need to maintain. This machine regulates not just the hot air but also the heating of water for plumbing needs.
This system not only provides the individuals inside the building with air, but also ensures that all parts of the structure have air, and that the air provided is clean, filtered and attempts to remove smoke, dust, moisture and other harmful elements. HVAC contractors will need to ensure that the equipment they put in to ventilate the structure can cope with the size of the building as well as the many different rooms within it and the activities that usually take place in the building.
Usually the AC system controls the humidity, ventilation, and coolness within a given area. Due to the comfort of the occupants as well as optimal conditions for hospital equipment and also those of office equipment, the centralization of a larger building such as offices and hospitals will need to be constantly under control.
Usually HVAC contractors like having only one central control unit for all three aspects of this field. Bigger institutions typically have a network that interconnects all three aspects to account for whatever weather or requirements the inhabitants need.
