Variable Refrigerant Flow

Variable refrigerant flow (VRF) can heat and cool different spaces simultaneously in a facility. It allows greater temperature control while conserving energy. 

Researchers from the Pacific Northwest National Laboratory (PNNL) found that VRF can achieve 34% energy savings compared to older systems.
