Overview

Variable Refrigerant Flow (VRF) zoning is an energy-efficient method of providing precise comfort control to indoor environments. Think of it as being able to heat and cool rooms simultaneously from the same HVAC system while achieving up to 40 SEER energy efficiency. VRF is state of the art best in class HVAC design and delivery for both residential and commercial applications.

VRF offers a wide variety of applications – everything from spot-cooling or -heating a single room in a home (using a split-ductless system) to a large commercial building with multiple floors and areas (that require individual comfort control delivered by a split-zoning system).

VRF moves refrigerant to the zone to be heated or cooled, allowing the temperature of that area to be more precisely controlled. It can simultaneously cool some zones while heating other areas or just provide comfort control to zones that are in use. (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.)

Ductless systems provide more building design flexibility and result in more usable space. Ducted systems allow you to combine multiple rooms into a single zone. Unlike other VRF systems, Mitsubishi Electric Cooling & Heating uses a two-pipe design which reduces the complexity, time and cost of installation with fewer refrigerant lines and connections.

INVERTER Compressor technology is highly responsive and efficient. The technology allows for compact, quiet units, flexibility of placement and gives architects and owners more design freedom with Integrated, simple to use controls.

Benefits:

  • Energy Efficiency – INVERTER-driven compressor technology, R2-Series can simultaneously heat and cool, virtually eliminating duct loss.
  • Zoned Comfort – Each individual zone can have personalized comfort as the system delivers the right amount of refrigerant to precisely meet the load in a space.
  • Quiet Operation – Indoor and outdoor units are so quiet that they can be placed just about anywhere, giving you more flexibility on how to use indoor and outdoor space. Outdoor units can even be placed directly under a window and quiet indoor units are perfect in environments that require minimal disruption like schools, places of worship, libraries and more.
  • System Simplicity – Mitsubishi Electric Cooling & Heating’s two-pipe system is simpler to install and service. Routine maintenance consists of changing filters and cleaning coils.
  • Aesthetics – HVAC systems don’t have to get in the way of design. Small outdoor units provide for flexibility of placement and indoor units can be painted to blend in with your environment. (Consult a certified contractor for details on how to safely paint the cabinets.
  • Lower Lifecycle Cost – Operate with minimum energy usage. Only service the zones that need it, which allows for less required maintenance.
  • Safety – Zoned structure does not recirculate air into other zones, reducing the spread of airborne contaminants and allergens.
