Variable refrigerant flow or VRF systems use refrigerant as both the cooling & heating medium.
This genre of proposal always consists of an outdoor component linked to many indoor units & avoids the need for HVAC duct! VRF technology is often used for commercial application because it caters to the unique demands of unusual zoes & offers a modular design that easily accommodates expansionâ€¦ Plus the outdoor units are exceptionally compact & lightweight, allowing it to be located on the roof or even tucked into a maintenance elevator.
Variable motor speeds & refrigerant flow add up to exceptional energy efficiency, often saving over 50% on utility costs. Reacting to the outdoor ambient temperature & the indoor control component setting, the VRF proposal operates the compressor at the precise level necessary to achieve perfect comfort. When another indoor component is activated, the outdoor component automatically recalculates the requirements from every indoor component & increases the compressor load to match demand. The ability of this technology to adjust makes it far more energy efficient than most alternative types of temperature control. This system of operation avoids temperature variations. In more traditional systems, the compressors are either off or on, & temperature swings occur whenever it stops & starts again. Because the VRF proposal varies the speed of the compressor, it operates continuously for longer periods & maintains even & ideal comfort at all times. A major benefit of VRF systems is the option for simultaneous heating & cooling, however one indoor component can be set to cooling while another provides heating. To further trim costs, the heat drawn from the section requiring air conditioning can be redirected & used in the room that requires heating.
