VRF Systems Features Features (continued)

Variable Refrigerant Flow Systems (VRF systems) are heating and cooling systems that utilize a technology developed in 1982. Like residential type smaller ductless units, a VRF systems use refrigerant as the cooling and heating medium. They consist of a single (or multiple, depending on capacity) outdoor condensing unit that circulates the conditioned refrigerant within the building to multiple indoor air handling units.

Mitsubishi Electric Cooling & Heating VRF systems features include:

  • Energy efficiency – VRF systems work at about 30% higher efficiency than conventional systems. INVERTER-driven compressor varies capacity to precisely meet load requirement while reducing power consumption. Supporting load diversity, the system’s total capacity can be distributed to each indoor unit via the branch circuit controller.
  • Quiet operation – conventional systems often start up and shut down with a bang and run with noisy rushes of air or water flow. The indoor and outdoor units of VRF systems operate at very low decibels providing a quiet indoor environment.
  • Control Options – several controller types are available for individual temperature control. The central controller can monitor, schedule and control up to 50 indoor units through a web browser interface. Multiple central controllers can be networked together with integrated centralized control software and systems can be tied to a Building Management System.
  • Safety – zoned structure does not recirculate air into other zones, reducing the spread of airborne contaminants and allergens. Whenever people inhale airborne dust at work, they are at risk of occupational disease. Year after year, both in developed and in developing countries, overexposure to contaminants causes disease, temporary and permanent disabilities and deaths. Contaminants and allergens in the workplace may also contaminate or reduce the quality of products, be the cause of fire and explosion, and damage the environment. An airborne disease can be caused by exposure to a source: an infected patient or animal, by being transferred from the infected person or animal’s mouth, nose, cut, or needle puncture. People receive the disease through a portal of entry: mouth, nose, cut, or needle puncture.
