A complete guide to VRF system

Air conditioning technology has progressed by leaps and bounds over the past couple of decades, making cooling and heating systems more affordable. Large-scale ductless air conditioning systems are no longer only for upmarket hotels or expensive highrise offices. VRF system, the acronym for Variable Refrigerant Flow system, has become an essential part of most industrial, institutional, commercial and residential facilities today.

These are designed to keep modern spaces warm during cold winter months and cool during summers so that occupants stay comfortable throughout the year. Variable Refrigerant Flow systems use refrigerants as a medium for heating and cooling purposes. If you want to know about this advanced refrigerant technology, scroll down and continue reading!

How does a VRF system work?

Variable Refrigerant Flow (VRF) technology allows you to connect multiple indoor units with a single outdoor unit with either two-heat recovery systems or heat pumps. VRF technology is incredibly complex; you can think of it as an enhanced version of ductless multi-split systems. These systems utilize heat recovery systems or heat pumps to produce heating and cooling for all outdoor and indoor units without using air ducts. These systems comprise a compressor with an outdoor coil and multiple indoor fan coil units.

The only difference is that the former provides simultaneous heating and cooling. The outdoor unit of VRF consists of compressors that come with inverter-driven fans that allow them to change their speed simply by adjusting the frequency of the power supply.

The quantity of refrigerant that the compressor will deliver to the indoor units depends on the demand of the indoor units. An indoor unit of the Variable Refrigerant Flow system sends a request to the outdoor unit for a definite amount of refrigerant; then, the outdoor unit delivers the specific amount of refrigerant to the individual units.

What are the benefits of the VRF system in commercial buildings?

It provides consistent comfort.

Variable Refrigerant Flow (VRF) technology allows the compressor units to identify the specific requirements for each building zone and provides it with just the right amount of refrigerants needed.

For example, a large room with many computer systems requires demands for high cooling, while a smaller meeting room where there is no heat-generating system has fewer cooling requirements. Thus, Variable Refrigerant Flow systems cater to the differences and provide more consistent comfort for your workspace.

It is energy efficient.

One of the most appealing benefits of the Variable Refrigerant Flow systems is that they promote energy efficiency. While other systems run at a single speed, VRF technology enables these systems to run at varying rates depending on the room’s current conditions. This means the system will run at a lower capacity and less frequently and consume less energy.

It is a noiseless air conditioning system.

The condensing units of the air conditioning systems are the loudest components, and these are located outside your facility in case of a VRF system. The indoor units of these systems are smaller and quieter; thus, with VRF, you don’t need to worry about noisy AC that disrupts the functioning of your business.

It is compact and provides flexible installation.

Another crucial benefit of Variable Refrigerant Flow (VRF) systems is that they are compact and ideal for even small spaces. This is because it has no distribution fans, pipes, and water pumps; as a result, it requires less room for installation. You don’t need a large area of your facility to install the heating and cooling equipment when you choose these systems.
