Until recently I had never heard of a VRF system.
This type of system eliminates the single, large and noisy central unit with multiple, smaller indoor air handlers that can be individually controlled.
Variable Refrigerant Flow systems have the ability to regulate the amount of refrigerant supplied to each air handler, making them extremely energy efficient. The compressor can accurately identify the needs of each zone and provide the precise amount of refrigerant necessary for maintaining consistent comfort. This innovation eliminates cold and hot spots and effectively handles humidity issues. While other types of systems are either blasting at max capacity or shut down completely, VRFs are designed to operate at varying speeds. They typically run at lower capacity less frequently, which consumes less energy. There’s the added perk of heat recovery. The system captures heat that is expelled during the cooling process and delivers this heat to other zones that require heating. Another benefit of a VRF system is quiet operation. The loud condensing unit is normally installed outside. The compact air handlers are especially quiet, and there’s none of the noise associated with ductwork. VRFs are great for homes or commercial buildings with limited space. They eliminate fans, ductwork, bulky pipes to circulated fluids and water pumps. They install easily and without major disruption and the modular design accommodates growing demands. More air handlers can be incorporated as needed. An added and surprising perk of a VRF system is the opportunity to simultaneously heat and air condition different zones. Especially in commercial operations, it’s very possible to require cooling in specific areas while others need heat.
