A VRF (Variable Refrigerant Flow) system is a commercial HVAC solution with components typically housed in white sheet metal enclosures. Operating at 450 volts (V) and ranging from 7 to 112 horsepower (HP), it efficiently regulates refrigerant flow to match varying load requirements, optimizing energy usage. Its sheet metal construction ensures durability and corrosion resistance. Features include precise temperature control, simultaneous heating and cooling, and zoning capabilities. Benefits comprise energy savings, quiet operation, and customizable comfort. Advantages include reduced ductwork, space savings, and ease of installation. VRF systems find application in large commercial spaces like office buildings, hotels, and shopping malls.
