FAQ: AIRSTAGE VRF Systems How can a VRF system achieve greater partial-load efficiency?
When a VRF system operates at partial-load capacity, heat transfer between the indoor and outdoor units is significantly improved. For example, when a 20-ton VRF system is operating at 50% capacity, it is delivering performance equivalent to that of a 10-ton system. It is as if a 10-ton system had the coil surface area of a 20-ton system. This greatly improves the efficiency of the VRF system.
