Air Conditioning Installation for Aldershot Insurance Company

Post Placeholder

An existing client of New-Air was moving premises into an old office building based in Aldershot.  There were existing systems at the premises which operated on R22 refrigerant which was phased out at the beginning of 2014 due to its ozone depleting properties.  The configuration of these systems didn’t meet our client’s requirements. We therefore carried out a site assessment to establish the functionality of the office areas and to enable us to calculate the heat loads within each area of the building.

It was noted that there was limited space to position external condensing units to the side of the premises. We therefore selected and installed Heat Pump VRF (Variable Refrigerant Flow) air conditioning systems consisting of a number of internal units connected to one external unit per floor of the office building.

Due to the lack of space in the ceiling voids in the building we installed a number of ceiling cassette type fan coils within the open plan office areas.  Conditioned air is distributed within the office environment via a number of four-way blow fan coils installed centrally within the suspended ceiling grid.

Compact ceiling cassette, split type air conditioning systems were installed in the separate meeting rooms to provide the occupants with independent control.

Two wall mounted systems which operate on a run and standby configuration were installed within the site IT server room to provide 100% back up in the event of system failure.

All of the new systems operate on energy efficient inverter technology and are charged with R410a ozone friendly refrigerant.

A centralised controller was installed within reception area of the building to provide the office manager with overall control of all installed systems.  There is the facility to set a 24hour programmable timer, control system set points as well a range of other administrator functions.

We now carry out the scheduled routine maintenance of all site equipment to ensure equipment efficiencies are maintained which includes an annual leak test of the site systems in line with the current FGas regulations.
