The Variable Refrigerant Volume (VRV) HVAC System
What exactly is this "variable refrigerant volume"? It’s an exciting comfort technology which Daikin invented in the early 1980s and expanded in the 1990s. It significantly improves energy efficiency in air conditioners and heat pumps, as well as other benefits.
With a standard, non-VRV HVAC system, the system turns on when the temperature sensors detect a room requires cooling or heating and runs for as long as necessary. With a VRV system, adjustments are made continuously by altering the amount of refrigerant sent to the evaporators. This means the system only works as much as necessary for a house to meet comfort requirements. Or, to make the explanation even shorter: a standard HVAC system is either "on" or "off," while a VRV system changes as it’s needed.
How Variable Refrigerant Volume Benefits a Home in Orlando, FL
Making the change to this type of HVAC system, either as a replacement for a heat pump or an air conditioning system, brings with it many advantages. The biggest one is how it boosts system energy efficiency. For an HVAC system to only operate at one volume of refrigerant consumes great amounts of energy. But when the system can "gear down" to only a percentage of its normal work load, it lowers energy consumption.
VRV systems are better at spreading comfort around rooms evenly: instead of running full-blast all the time, which won’t benefit all rooms, the system modulates itself for better distribution. A homeowner has more precise control over the temperature of the home. And because VRV HVAC systems often run at lower power, they make less noise than standard air conditioners and heat pumps.
What’s the Difference With a Variable Refrigerant Flow (VRF) System?
Essentially, variable refrigerant flow is a different name for the same technology use in variable refrigerant volume systems. Daikin has registered variable refrigerant volume as an official trademark, so it’s the term you’ll hear us use most often. Other brands use variable refrigerant flow. You may run into both—but they’re the same beneficial technology for indoor comfort.
VRV is not suitable to all homes, and installing one requires updates to climate controls and other parts of the original HVAC system.
