VRV systems also known as VRF (Variable Refrigerant Flow) VRV System Air Conditioning use advanced inverter technology to control the amount of refrigerant sent to each indoor unit, allowing for simultaneous heating and cooling across different zones. This means you can maintain different temperatures in separate rooms or areas of a building, all from one outdoor unit.Originally developed by Daikin, VRV systems are now offered by several top manufacturers, and are especially popular in multi-story buildings, large homes, hotels, office complexes, retail spaces, and medical facilities.
