Variable Refrigerant Flow or VRF Systems

What is Variable Refrigerant Flow or VRF Systems?

Variable Refrigerant Flow (VRF) systems are similar to the multi-split systems which connect one outdoor unit to several indoor units. However, multi-split systems turn OFF or ON completely in response to one master controller, whereas VRF systems continually adjust the flow of refrigerant to each indoor evaporator

Why Would I Need A Variable Refrigerant Flow System?

The main advantage of a variable refrigerant flow system is its ability to respond individually to fluctuations in space load conditions. The user can set the ambient temperature of each room as per his/her requirements and the system will automatically adjust the refrigerant flow to suit the requirement.

VRF systems enable wide capacity modulation and bring rooms to the desired temperature extremely quickly and keep temperature fluctuations to minimum. The technology offers excellent dehumidification performance for optimal room humidity regardless of outside conditions. Any area in the building will always be exactly at the right temperature and humidity, ensuring total comfort for their occupants.

VRF systems are capable of simultaneous cooling and heating. Each individual indoor unit can be controlled by a programmable thermostat. Most VRF manufacturers offer a centralised control option, which enables the user to monitor  and control the entire system from a single location or via the internet.
