Question

Variable refrigerant flow (VRF) systems modulate the volume of refrigerant that is pumped through the system. This allows?

A. Lower operation cost

B. Better operating efficiencies

C. Matching system capacity to the load

D. All the above

Expert Solution

Step 1

VRF is a technology that changes the amount of refrigerant in a system according to the needs of a building at any given time. A minimum amount of energy is required to maintain the set temperature; it turns off automatically if there are no people in a room. This unique mechanism provides greater efficiency in the long term. Moreover, end-users simultaneously save on energy costs and reduce carbon dioxide emissions.
