VRF System – Variable Refrigerant Flow

VRF System utilizes a heating and cooling technology developed in 1982. Like residential type smaller ductless units, a VRF system uses refrigerant as the cooling and heating medium. The system consists of a single outdoor condensing unit that circulated the conditioned refrigerant within the building to multiple indoor air handling units.

Mitsubishi Electric Cooling & Heating features include:

  • Design and installation flexibility – installation is possible in tight spaces because the two-pipe design and compact components of VRF system requires less space than conventional systems.
  • Lower life-cycle costs – energy savings as well as reductions in total installation and maintenance costs result in a lower life-cycle cost for the system.
  • Lighter weight – these systems are 31 percent lighter than comparable chilled water systems. The result is easier and cheaper transportation expenses. The required structural support is lighter than that of regular air conditioning equipment due to the VRF system lighter weight and the modular design that allows the load to be distributed across an existing structure.
  • Discreet indoor units – a wide variety of indoor unit styles offer design flexibility. Ductless option includes wall-mounted, floor-standing, ceiling-recessed cassette and ceiling-suspended. Ducted options include vertical floor-standing-concealed and horizontal ceiling-concealed.
  • Zoning – this is a method that provided precise temperature control to buildings with multiple floors and areas by moving refrigerant through piping to the zone to be cooled or heated. VRF system can at the same time cool one zone while heating another. Apart from of time of day, sunshine or cloudy and rainy weather, season of the year or any additional requirements, VRF system provides unmatched comfort within the space. Mitsubishi Electric Cooling & Heating VRF system with multiple indoor (air-handling) evaporator units connected to an outdoor compressor unit can deliver just the right amount of refrigerant to precisely meet each zone’s load. Indoor units can be controlled to operate only in those occupied areas that need conditioning; indoor units in vacant areas can be turned off.  By conditioning only the occupied areas, heating or cooling capacity, as well as required energy is not wasted.
