projection requirements. The existing bypass cooling coil would be bypassed with a new cooling coil and this utilised for the latent cooling of the outside air only. A secondary sensible coil was installed in lieu of the existing HEPA filtration section, and the new arrangement provided significant reduction in cooling demand and energy savings, completely removing the need for reheating post latent cooling. Air handling unit 2 (AHU02) served the
rest of the facility, as its size and components were suitable for the newly calculated demand, with limited modifications.
HVAC chilled water An existing heat pump chiller for the HVAC chilled water air handling units cooling coils was replaced with heat pump chillers for a new HVAC cooling only chiller, which then linked to the existing primary circuit. Operating at 5°C flow and 11°C return. The air handling unit coil sizes were sized based on the design air volume +10 per cent. A further margin was added to the chilled water flow rate to allow for pipe losses. Most of the cooling requirement will only be needed during warm periods; there is a base load all year round demanded by the moulding lines when in operation, therefore, a second standard chiller, is in situ for use on a standby arrangement. It would also offer free cooling of the chilled water system during colder months. Regarding maintaining the room
temperature profile in the moulding room, the temperature difference between the room air and supply air was not to exceed 8°C. The moulding process required the ideal supply chilled water temperature at 24°C. The low flow rate through individual equipment provided a high return

temperature of up to 75°C, with potential to peak at up to 100°C. It was agreed dry coolers that provide
refrigerant free cooling utilising ambient air would deliver a good solution. If the ambient condition was lower than the required chilled water condition. A dry cooling system delivering chilled water at 20°C was provided. The process cooling water being used to cool down the melted plastic in the moulding tool. During days with high ambient temperature the system is supplemented with the HVAC chilled water system that cools down the higher temperature chilled water from the dry coolers via a plate heat exchanger. A new vacuum system has been
installed to support the process chilled water operation, to evacuate the residue water from the moulding tools, once disconnected from the process chilled water loop. There is also potential to reuse this waste water, which is under an ongoing assessment in terms of cost vs. payback. Cook continues: “This is one of the first
of our facilities to include these sustainable production process solutions. We will be evaluating the benefits as we start operations. Although we understand the base usage, we naturally need the plant up and running fully to understand the whole picture. “We very much hope aspects of what
we have introduced will benefit the rest of the business, as we look at rolling out similar approaches across our other
facilities where appropriate as we make further strides towards greater carbon reduction. It will vary from building to building as to what is appropriate to introduce into some of our older buildings on site, as it’s not only about saving the energy it’s about insulation to ensure we are maximising the loss and keep the building operating efficiently. We are looking at alternatives, such as solar panels etc. So, we are addressing buildings as there is a need to do so, and we are looking at these other alternatives which we can integrate into existing operations as appropriate.”
The impact of phased handovers while maintaining operations It is always a challenge when there is a requirement to handover on a piecemeal basis while construction and client operations is continuing, yet it is also a growing requirement of today’s business practice. But it can stretch relations and demands close co-operation. Cook understood it would be challenging for both parties: “The main thing was that it wasn’t just about keeping two businesses running, it was that part of it was still operating as a clean environment and we had to shield that area to stop particle transmission as well as keeping it cool enough. Unfortunately, it was compounded by the fact we had a hot spell at that time too, up to 31+ degrees and the work environment runs at 21 degrees, plus or minus two degrees, so trying to maintain those temperatures stretched everyone. Especially as we had the main air handler unit down for that area. Nonetheless, we got through it but there were days when we did have to concede and stop production, but these were minimal and not critical and were business decisions that we had to take. But throughout we had excellent support from BES, when we needed to upgrade or increase the number of units to keep the area cool, BES sourced alternatives. Also, when we had a failure on one of the units, they supported us with solutions as quickly as they could.”
