VRF Air Con

Variable refrigerant flow VRF air conditioning

VRF systems improve comfort,save money and improve comfort

Inverters respond to the changes in the cooling or heating requirements within the space that is being air conditioned by controlling a variable speed compressor, or multiple compressors of varying capacity. A sophisticated control system will then switch between the cooling and heating modes. More advanced inverter systems allow indoor units to heat or cool independently of others in different zones in the building, providing energy saviR22 BAN IN AIR CONngs when heating and cooling are required at the same time.

Calculate the size your system needs to be

Our calculator will help you discover the size of the VRF system you may require. However, like even the simplest of air conditioning installations (and VRF is a deal more sophisticated), correct HVAC design and specification by a qualified engineer is a must.

Hybrid VRF

Hybrid VRF is the latest development in air conditioning that optimises the benefits of refrigerant and water to deliver the best of both worlds. It combines the comfort and flexibility of  traditional VRF chilling but removes the need to use refrigerants in occupied spaces and, with this, the requirement for leak detection equipment. As legislation has become ever more stringent to protect the environment, for example F-Gas, R22 and BS EN378, it makes it easier for a business to achieve its CSR targets and reduces the expense and complications of compliance.


Why VRF Hybrid is really very clever:

  • Hybrid Branch Controller (HBC)  This is the clever box that controls the system. It connects to an external City Multi unit using standard refrigerant pipes  and then on to indoor fan coils but now using water, all in its unique two-pipe system. This can provide cooling and heating to sixteen different ducted, cassette or floor-standing units.
  • How effective is it?   Up to fifty individual areas or rooms can be heated and cooled simultaneous using two main HBC’s and two sub units, these connected to one City Multi outdoor unit. This creates a powerful system with centralised control and individual operation for simultaneous cooling or heating. All with the flexibility of VRF design, phased installation and no need for refrigerants in occupied rooms. It also reduces the total volume of refrigerant in the system.

The benefits of Inverter technology

Inverter technology is the big innovation in climate control. It optimises efficiency through a simple principle: to adjust the energy used to the precise requirements of the rooms in your building. Inverters are the ‘must have’ investment if you use your air conditioning all year round for heating as well as cooling.

  • Improved comfort   Fast start-up times and the continual adjustment of cooling and heating outputs ensure that the required room temperature is reached quickly and constantly maintained.They are quiet and there are no temperature fluctuations.
  • Energy efficiency   Inverter match the power used to actual requirements – no more, no less – in this way energy consumptions can be up to 5o% less than a traditional system.


Thought about ECA’s?

ETL enhanced capital allowancesEnhanced Capital Allowances (ECA) scheme rewards investment in energy saving systems on the Energy Technology List (ETL) with accelerated tax relief. Businesses may be able to claim 100% first year capital allowances and write off costs against taxable profits in the year of purchase.
