New air-conditioning units meet old R22 installation in Belfast

Replacing the1992 Mitsubishi Electric VRF air-conditioning system in this building in Belfast required only new indoor units, condensing unit and branch controller.

One of the earliest Mitsubishi Electric R2 VRF air-conditioning systems using R22 has been successfully replaced with minimal disruption at Heyn Handling in Belfast. The work was carried out by Air Cool Engineering (NI), which identified a number of energy-saving opportunities to help make the replacement and upgrade realistic.

As existing R22 pipework, control wiring, drains and electrics were already in place, Air Cool Engineering only had to replace indoor units, the branch controller and condensing unit with Mitsubishi’s new R Series. While the system was being upgraded, Heyn Handling also took the opportunity to provide air conditioning in offices that previously had none.

Martin Mullan of Air Cool Engineering, explains, ‘Heyn Handling was very happy with the performance of its existing Mitsubishi R22 system, which was installed in 1992, but realised that it was nearing the end of its life and needed replacing. We advised our client that an upgraded model was now available — providing high-performance, energy-saving and cost-effective cooling and heating in their offices.

‘As the new R2 Series could utilise and “recycle” the existing R22 pipework, electrics, drains and control wiring, significant savings were made on the install costs and timeframe required to complete the project. With minimal disruption to the operation of a busy office, we were delighted to complete the replacement install over a 2-week period.’
