Variable Refrigerant Flow Systems Use

Modern vrf systems provide some major advantages such as zoning individual temperature control minimized ductwork excluding the need for secondary fluids chilled water or hot water distribution and.

Variable refrigerant flow systems use.

Variable refrigerant flow also known as variable refrigerant volume is an hvac technology invented by daikin industries ltd. The variable refrigerant flow enhancement comes with multiple indoor unit evaporators or condensers up to 16 with various manufacturers utilized with a single outdoor condensing unit or heat pump. They are the primary hvac system choice in europe japan china and other parts of the world and are beginning to penetrate the u s. Overview water source vrf profile 2016 variable refrigerant flow vrf systems are typically all electric systems that use air or water source heat pumps to provide space heating and or cooling to a building s spaces.

This fully integrated high performing hvac system solution is designed to deliver customized comfort throughout any commercial space. Variable refrigerant flow vrf systems are gaining in popularity and are used as an enhanced version of multi split systems featuring simultaneous heating and cooling as well as heat recovery capabilities. This refrigerant is conditioned by a single or multiple condensing units and is circulated within the building to multiple indoor units. Regardless of the capacity energy efficiency functionality or performance monitoring requirements our vrf systems solutions featuring trane mitsubishi electric vrf technology are.

Identify the codes and standards that dictate the design and use of vrf systems. Variable refrigerant flow vrf is an air condition system configuration where there is one outdoor condensing unit and multiple indoor units. Even though it has been widely used in other countries for over 30 years vrf which stands for variable refrigerant flow has only been available in the united states since the early 2000s. The term variable refrigerant flow refers to the ability of the system to control the amount of refrigerant flowing to the multiple evaporators indoor units enabling the use of many evaporators of differing capacities and configurations connected to a single condensing unit.

Variable refrigerant flow systems focuses on vrf systems which use a combination of zone level indoor terminals and outdoor components to provide heating and air conditioning. Like ductless minisplits vrfs use refrigerant as the cooling and heating medium. Vrf is known for its superior energy efficiency and ability to offer a quick return on investment in many applications. Vrf systems unlike conventional chiller based systems allow for varying degrees of cooling in only certain areas reducing energy consumption.

Variable refrigerant flow vrf heating ventilation and air conditioning hvac systems are one possible tool to meet gsa s objectives.
