The installation is now complete. This refrigerant is conditioned by a single or multiple condensing units which may be outdoors or indoors water or air cooled and is circulated within the. You want better air flow. The simplest explanation of vrf is to describe it as a large scale ductless hvac system that can perform at a high capacity.

Like ductless minisplits vrfs use refrigerant as the cooling and heating medium. The diagram above indicates how a single outdoor vrf condensing unit can serve various styles of indoor units wall mounted ceiling cassette concealed ducted ptac style. Air velocity that is below 0 15 m s is considered still air as defined by ashrae 55 2013 american society of heating refrigerating and air conditioning engineers. Complexity is the name of the game when describing the technical nature of how variable refrigerant flow technology works.

Vrf is a technology that can reduce energy losses and thus improve air conditioner efficiency in certain installations. Vrf systems are nontraditional hvac systems in comparison with conventional ducted systems circulating the air or chilled water throughout the building. A demonstration on how to use the daikin controller and the advantage air controller is provided to the owner. These systems have continued to advance over the years and numerous other notable manufacturers like lg mitsubishi and trane also offer versions of vrf systems.
