VRF Systems

Application

VRF (variable refrigerant flow) air conditioning is a type of system where a single, or multiple, outdoor units are connected to a number of indoor fan coils to provide an integral system. This system is also known as VRV (variable refrigerant volume) and is available in either 2 pipe for cooling or heating, and 3 pipe for simultaneous cooling and heating.

Features

VRF systems are suited to office blocks, hotels, or any building where there are a significant number of individual rooms to be air conditioned. This type of installation can offer benefits in terms of energy consumption, heat recovery and control systems.

Many systems incorporate all inverter controlled compressors, these respond to changes in cooling or heating demand to precisely meet the changing requirement. Most systems are designed to operate on the latest generation of refrigerants such as R410a.

Outdoor units are capable of handling very long pipe runs and can therefore often be positioned out of sight. This also means that the number of outdoor units can be reduced for a given total cooling requirement; this can be as high as 90 kW on a single system.

All types of indoor units can be connected to a VRF system in any combination - ducted, cassette, wall mount etc. Mini VRV systems are also available which can provide similar benefits but on a smaller scale, typically up to 16 kW of cooling or heating.
