Variable Refrigerant Flow Systems Use

Variable refrigerant flow vrf is an air condition system configuration where there is one outdoor condensing unit and multiple indoor units.

Variable refrigerant flow systems use.

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. 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. Due to the advanced use of variable speed compressors drives and inverter driven fans many manufacturers of these systems are capable of providing simultaneous heating and cooling through their indoor units. Variable refrigerant flow vrf heating ventilation and air conditioning hvac systems are one possible tool to meet gsa s objectives.

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. 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. 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. Vrf systems unlike conventional chiller based systems allow for varying degrees of cooling in only certain areas reducing energy consumption.

Vrf systems can condition multiple zones in a building each of which may have different heating and cooling needs. Vrf is known for its superior energy efficiency and ability to offer a quick return on investment in many applications. Variable refrigerant flow also known as variable refrigerant volume is an hvac technology invented by daikin industries ltd. Identify the codes and standards that dictate the design and use of vrf systems.

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. Like ductless minisplits vrfs use refrigerant as the cooling and heating medium. Trane has paired applications knowledge and expertise with its extensive equipment and controls offerings to provide variable refrigerant flow vrf systems solutions.
