VRF Variable Refrigerant Flow

About VRF Variable Refrigerant Flow

A Variable Refrigerant Flow (VRF) system is an HVAC system that uses refrigerant to provide heating and cooling to multiple zones in a building. VRF systems are also known as variable refrigerant volume (VRV) systems, though VRV is a trademark of Daikin Industries, Ltd.

Here are some features of VRF systems:

• Energy efficiency: VRF systems can operate at part-load continuously, which can significantly increase overall efficiency.
• Individualized temperature control: VRF systems can regulate refrigerant flow to match the heating and cooling needs of different zones.
• Quiet operation: VRF systems can operate quietly even when running at full capacity.
• Reduced structural impact: VRF systems use smaller penetrations for refrigerant pipes instead of ducts, which can reduce the height above a dropped ceiling.

• VRF systems can switch to heating mode during winter without additional equipment.
• VRF systems are used in a variety of applications, including mixed-use facilities that have many different types of spaces that need to be kept at different temperatures
