Case Studies
Business Park Offices
The photos below are from whilst we were completing a mechanical fit in Watford. The landlord owned various buildings on the business park and there was a relatively new Daikin chiller on the roof that was surplus to requirements due to the whole building converting to VRF/V.
There was however another chiller at the end of its life on another building so whilst in contract and to make space for our new condenser banks we successfully disconnected both chillers, controls power and water, craned the old one off to be disposed, then the new one off one building, re set up the crane location to lift it onto the other building in the same day.
Then the week that followed, re piped, dosed, insulation and cladding, power, BMS, water balancing and commissioning. Needless to say good planning, preparation and communication meant this all went smoothly and we envisage for every project.
B&Q Distribution Centre, Worksop
As a Daikin D1+ dealer & installer, Airmaster Air Conditioning Ltd along with several other local D1+ rated companies were invited to tender for the large Air Conditioning replacement project at the B&Q Distribution Centre in Worksop.
We were asked to present 2 tender applications, the first to carry out a full like-for-like AC replacement of the existing 15 year old Sanyo systems, the second was to put forward our own design & build application.
The Airmaster Contracts team presented a perfect tender application which included a full Hevacomp thermal imaging building report, giving us the precise up to date technology to supply the correct AC equipment in the right areas, this was carried out by our in house Design team at Airmaster Air Conditioning Ltd.
The project included; the full removal of the existing AC systems, with full replacement of 6 large Daikin Europe VRF systems, 2 Comms room double split systems, the project also included the Daikin ‘reclaim with confidence’ and ‘commission with confidence’ package. This was finished with a full mains electrical upgrade to all internal and external AC systems.
This was carried out on a very tight 8 week timeframe, along with all buildings still in full use and strict Covid restrictions earlier this year, the Airmaster Air Conditioning Ltd team pulled out all the stops to complete a fantastic project on time.
The B&Q Worksop Engineering & Facilities Manager Dave Horton and his team were brilliant to work with and had nothing but praise for the Airmaster installation Engineers.

Paul Wilkins, Corporate Clients Division Manager at Daikin
“Well done to everyone involved at Airmaster Air Conditioning Ltd. Your tender submission was spot on, fulfilling the brief perfectly and then going beyond it too. The project ran like clockwork thanks to your professionalism. The client understood the long-term importance of marrying a high-quality installation with high quality equipment. A great project.”
Cold room supply and install - Doncaster
Airmaster have completed the supply and install of a cold room for Highfield Coffee Social in Doncaster as part of their fit out of their new coffee shop.
Main Contractor: Togel Contractors
Project Manager: Stephanie Lagan–Collins, Fatfish Design
Airmaster supplied and installed the walk-in chiller cold room, refrigeration equipment, cold room shelving and a personnel entrapment alarm.
We also supplied and installed a stainless-steel kitchen canopy with integrated supply and extract, along with stainless steel wall cladding.
The existing A/C fan coil units were relocated, and we supplied and installed additional heat recovery units, along with upgrading all the ceiling grilles to matte black to fit with the new interior decor of the public facing coffee shop space.

“We have worked with Airmaster for around 20 years for all our air conditioning requirements throughout our business sites in Doncaster, including PPM, servicing, server room design and install when relocating offices.
When we have had problems arise in the past, all it has taken is a phone call to Airmaster, and on many occasions they have gone the extra mile to help us resolve the issue quickly and efficiently.
So, when we began to develop plans for Highfield Coffee Social, we knew we were in capable hands with the team to fulfil our specific requirements. The whole process, from initial plans through to fit and commission, was faultless, and we are delighted with the outcome.”

Water-cooled VRV perfect solution for Richmond office refurbishment
A landmark 1980s ‘head office’ building in Richmond, London, has been given a new lease of life – and a fresh long-term tenant – after a £5 million refurbishment that included installation of Daikin VRV-W water- cooled air conditioning.
The 33,000 square foot four-storey building at 63 Kew Road – former UK headquarters of Pepsi Cola – is now home to the leading online marketplace for creative small businesses notonthehighstreet.com, which has taken a 10-year lease.
Owned by Low Carbon Workplace, the building has been substantially upgraded to raise its Energy Performance Certificate rating from E to B and to achieve a BREEAM Excellent rating. The improved ratings also meet the London Borough of Richmond’s target for a 40% reduction in carbon emissions.
Low Carbon Workplace is a a partnership, launched in 2010, between the Carbon Trust, fund manager Columbia Threadneedle Investments and property developer Stanhope.
The partnership acquires commercial office buildings and refurbishes them into modern, energy efficient workplaces.
In selecting the Kew Road building’s new heating and cooling system, noise criteria and line-of-sight constraints ruled out chillers and air-cooled VRV outdoor units. Water-cooled VRV, on the other hand, could be contained – out of sight and earshot – in a plant room.
VRV-W also offered the efficiency advantage of two-stage heat recovery - within each system and between systems on the water loop. This two-stage recovery substantially improves overall energy efficiency especially in situations where cooling is required even in winter.
Heat recovery was an obvious choice for a building with different aspects developing variable conditions that required simultaneous heating and cooling. The original design was also based on a Cat A selection process to ensure the system would have maximum fl exibility to accommodate the requirements of any future tenants.
There is a flexible and energy efficient control strategy to attain both the EPC and BREEAM scores required by Low Carbon Workplace. The strategy includes PIR movement sensors linked to Daikin RTD interfaces to provide the control inputs for one or more FCUs to optimise conditions when people are present, but to drift from the set point after no response from the PIR, and eventually switch off.
To allow for Individual control, one branch selector box is provided per FCU. The 20% tempered fresh air delivered to the FCUs is controlled by dampers and CO2 sensors, which further enhances efficiency. There are no local controllers, with the system controlled centrally by Daikin Intelligent Touch Managers – facilitating sub-metering of the building if it is subsequently let to multiple tenants. The system gives individual tenants the facility to control their environment through web-based access to the ITMs.
Sheffield - based Daikin D1+ Premium Partner Airmaster installed six systems totalling 13 condensers, which generate the total heating and cooling requirement for all floors and an air curtain in the lobby. Another four condensers serve the building’s two air handling units, which supply tempered air at 18oC to the rear of fan coil units (FCUs) throughout the building. The building’s total calculated load is 427kW (peak instantaneous: 348kW).
Two low-height, low-noise Guntner adiabatic dry air coolers reject heat from the water loop to the roof. A 546kW boiler generates hot water for the building and heat injection to the water loop to maintain a fixed 40oC flow to the Daikin VRV-W condensers during cold weather.
To fit the boiler and condensers into the plant room, the condensers were located using racking, one above the other. This satisfied the requirements for heating and cooling plant without compromising design – or the lettable floor area.
All FCUs are of the FXDQ type – slim concealed ceiling units, which can be mounted in ceiling voids as small as 240mm.
These medium external static pressure units can be used with flexible ducts of varying lengths. They are specially developed for small or well-insulated rooms such as hotel bedrooms and small offices – and so are ideal for ensuring future flexibility of the office layout at 63 Kew Road.
