Theatre Air Conditioning Replacement

Air Options where asked to review the existing air conditioning systems installed within a theatre, given these where ageing and generally in poor condition.


Following inspection we found that the units overall where very old and we were unlikely to be able to repair / get the systems operational and reliable without excessive costs.

We therefore recommended that the units where decommissioned and removed / replaced with new, which would offer increased capacity as well as improved energy efficiency.


Existing indoor systems had previously been over painted to match with the walls / decor that made matching up equivalent units a little more difficult given all nameplates had been painted. We however undertook some load calculations on the area taking into account occupancy / lighting loads to determine recommended capacities as well as using some of our historical knowledge of the old units to determine existing unit capacities and performance.

The replacement systems where chosen from Mitsubishi Electrics Mr Slim “Power Inverter” range of products as these proved to be a perfect fit as well as significantly improving the overall energy efficiency.

As part of the installation we dismantled the indoor units and had these professionally primed and sprayed to a site specific RAL colour to match the walls.

These systems where also fitted with the hard wired remote controllers located in the control room as opposed to locally allowing for improved operation during the course of operation.

All replacement systems where phased around the use of the theatre and left each day in a clean and tidy manorĀ  to allow for the use of the area by the client.


Since installation the client now benefits from a warranted and reliable solution with improved temperature control / comfort for the public watching the performances.
