Variable Refrigerant Flow (VRF) air conditioners are advanced heating, cooling and ventilation systems that operate at variable fluid flow rates. These systems are designed to supply air or water at different temperatures to different areas within the building and are designed to be energy efficient. VRF air conditioners have the following basic functions:

Variable fluid flow

VRF systems are designed to supply liquid (usually refrigerant gas) at different temperatures to various indoor units. This provides the flexibility to set the desired temperature level for each room or zone.

Inverter technology

VRF systems often use inverter technology. This technology optimizes energy consumption and enables more precise temperature control by continuously adjusting the compressor speed.

Multiple indoor units

A VRF system typically includes an outdoor unit and several indoor units. Indoor units can supply air or water to different rooms or areas.

Interior zoning

VRF systems allow for different temperature control for different areas within the building. This allows energy savings to be achieved depending on user needs.

Heat recovery

Thanks to their heat recovery capabilities, VRF systems can save energy by transferring heat extracted from one area to another.

Central control system

VRF systems are generally managed by a central control system. This enables central control and monitoring of the entire system.

Flexible installation options

VRF systems can be adapted to various installation options. A single outdoor unit can be connected to multiple indoor units, allowing for flexible configuration within the building.

Energy efficiency

Features such as inverter technology, variable fluid flow rate and heat recovery make VRF systems energy efficient. These systems save energy compared to traditional HVAC systems.

VRF air conditioners are widely used in office buildings, hotels, hospitals and other commercial or industrial facilities. In terms of energy efficiency, flexibility and indoor space layout requirements, VRF systems are very popular.
