What Does HVAC-R Stand For?
HVAC-R stands for heating, ventilation, air conditioning and refrigeration.
HVACR generally mentions to the mechanical systems used in the heating, cooling and ventilation of indoor environments. The people who deal with them are called HVAC-R technicians. The trade involves installing, maintaining and repairing climate-control devices such as air conditioners, furnaces, refrigerators and freezer units.
HVAC-R Systems
Industrial and commercial HVAC-R systems include such components as air ducts, piping, vents and thermostats. Technicians are responsible for installing and maintaining these systems and guaranteeing that each part is functioning properly. Refrigerators, freezers and air conditioners operate with liquid refrigerants to expel heat from indoor areas. Similarly, heating systems use oil, gas and electric components to produce heat, which is then distributed through air ducts and vents.
