What is VRF air conditioning? What types of VRF air conditioning systems?

 Not sure what VRF is? You’re not alone. VRF air conditioning is really common in the UK – you’ll find it in offices, restaurants, shops, and homes. But lots of people aren’t sure what systems the term refers to or how they work.


Whether you’re thinking about installing air conditioning or want to find out more about your existing system, you’re in the right place. Here’s everything you need to know about what VRF air conditioning is, how it works, and why it could be a good choice for you.

What's VRF air conditioning? 

VRF stands for 'variable refrigerant flow'. A VRF air conditioning system is comprised of one external unit and multiple internal units. 


The primary concern that makes a VRF system not the same as different kinds of air conditioning is that you can control each internal unit independently. This is called zonal control. For instance, you can have distinctive internal units set at various temperatures, or make them run while different ones are turned off. 


VRF systems can modify how much refrigerant flows to each internal unit individually – this is the thing that gives them their name. It's this variable flow that makes it conceivable to utilize multiple various kinds of internal units in a single system and control their temperature settings separately. 


VRF systems are regularly alluded to as 'multi-split systems' – this is on the grounds that they feature multiple internal units connected to one external unit.

What types of VRF air conditioning systems are there? 

There are 3 fundamental types of VRF systems that are utilized in the UK. These are: 

  • Heat pump systems 

  • Heat recovery systems 

  • Cooling only systems 


Heat pump systems are the most mainstream out of these 3. They can heat and cool your air, in spite of the fact that you can't have one internal unit heating while another's cooling. 


Heat recovery systems are more uncommon. They likewise heat and cool, yet it's conceivable to utilize one unit for heating while another's cooling. 


Cooling only systems likewise aren't as famous. These units can chill your property off in a warm climate yet can't give heating.

VRF Piping

VRF manufactures need that you just use their proprietary code to style the refrigeration piping for the installation of their VRF systems. You or your engineer can have to be compelled to have a cooling and heating load to import or use with the VRF Piping. victimisation energy modeling code is nice for warmth Recovery Systems and optimizing segmentation layout. Below you'll notice an inventory of links to every of the Manufactures free VRF Piping style code. Here is what you'll expect to receive. VRF Piping Diagram The VRF manufactures computer code can offer a schematic piping diagram showing all the out of doors & indoor units at the side of any accessories. The schematic piping diagram also will show the pipe sizes and lengths that were employed in the calculation. there'll even be model numbers for the instrumentality and accessories with the schematic. All fittings and valves area unit reborn to constant length of pipe once scheming piping and system size...

Are VRF Systems energy-efficient?

Customary Direct Expansion Air-Conditioners offer no tweak because of changes in the space load conditions. Their blower activity is a basic on-off type, making it hard to keep up alluring indoor conditions. With Var iable Refrigerant Flow ( VRF) Technology, it is presently conceivable to interface numerous Indoor Units with a single Outdoor Unit.  The blower is Inverter Driven or Digital Scroll type. This blower lessens its speed and henceforth power devoured in light of real requests from room temperature setting or from a diminished amount of Indoor Units inactivity. Both ductless and ducted Indoor Units can be associated with regular refrigerant lines from Outdoor Units.  The significant preferred position of this sort of framework is its Energy Efficiency. As Air Conditioning loads for a structure is at its pinnacle just 1% of the time, the rest of the time framework is required to work at part load conditions. A framework that works at part load conditions ...
