HVAC SYSTEM

HVAC SYSTEM:-

HVAC system stands for Heating Ventilation and Air Conditioning system.

Heating, Ventilating, and Air Conditioning (HVAC) equipment perform heating and/or cooling for residential, commercial or industrial buildings.

The HVAC system may also be responsible for providing fresh outdoor air to dilute interior airborne contaminants such as odors from occupants, volatile organic compounds (VOC’s) emitted from interior furnishings, chemicals used for cleaning, etc.

Usually a sensing device is used to compare the actual state (e.g., temperature) with a target state.

Then the control system draws a conclusion what action has to be taken (e.g., start the blower).

A properly designed system will provide a comfortable indoor environment year round when properly maintained.
