HVAC
HVAC (Heating, Ventilation and Air Conditioning) is the technology and equipment responsible for regulating and maintaining the air temperature and quality of residential, commercial and industrial buildings.
HVAC systems use heating and air conditioning to keep indoor conditions at comfortable temperatures. Thermostats constantly monitor temperature and turn heaters, fans and air conditioners on or off depending on the requirements of the facility or room. Humidistats, hygrostats, and other air quality sensors also help with this task.
In addition to heating and cooling, ventilation exchanges or replaces air in an indoor space to promote high indoor air quality. Ventilation assists in temperature control, but also is responsible for removing moisture, odors, smoke, and dust from the environment. Ventilation is particularly important in many processing plants, to remove harmful gases from the air and to protect sensitive equipment.
