Overview and Benefits

Variable Refrigerant Flow (VRF) zoning is an energy-efficient method of providing precise comfort control to indoor environments:

• Wide variety of applications - everything from spot cooling or heating a single room in a home with a split-ductless system to a large commercial building with multiple floors and areas (zones) that require individual comfort control delivered by a split-zoning system
• Zones are single or multiple room spaces that are conditioned to a set temperature and are operated independently from other rooms within the same structure
• VRF moves refrigerant to the zone to be heated or cooled, allowing the temperature of that zone to be more precisely controlled - can simultaneously cool some zones while heating other zones or only provide comfort control to zones that are in use.
• Ductless systems provide more flexibility for building design and result in more usable space
• Ducted systems allow you to combine multiple rooms into a single zone
• Unlike other VRF systems, MEHVAC uses a two-pipe design - reduces the complexity, time and cost of installation with fewer refrigerant lines and connections

• INVERTER Compressor technology is highly responsive and efficient
• Compact, quiet units that allow for flexibility of placement
• Gives architects and owner more design freedom
• Integrated, simple to use controls
