- 2. 02 PROJECT: Debenhams Milton Keynes Project Value 贈400k A store with approximately 104,000sq ft of retail space spread over three floors; lower ground, ground and first floor. The main plant deck serving all of these areas is located on car park levels 1 & 2. The project comprised of replacing the 9 x 140kw R22 refrigerant heat pumps that served 9 x AHUs. The AHUs supplied the ma- jority of the existing air conditioning and comfort cooling systems that served the store. We carried out all associated works such as sprinkler modification and any necessary building works. The contract was on a design/build basis and we were responsible for liaising, when necessary, with the store management, statutory parties and landlords representatives to ensure all necessary approvals were in place to carry out the works. All works met with the manufactures technical stipulations. Overall cooling load to front of house sales areas is no less than the minimum loading of 135w/m2 with the public restaurant areas being considered in the range of 175w/m2 to 200w/m2. A full, detailed design summary was submitted covering all areas for consideration. As the heat pumps, which contained the R22 refrigerant, sat on proprietary steelwork supports on car park level 2 (in a dedicated Debenhams plant zone) the heat pumps were craned off the building and new support steels were installed to take the new inverter Toshiba condenser units. The AHUs were in relatively good condition and were overhauled accordingly as part of the proposed scope of works. These works comprised of: Removing the existing 400Kg R22 DX coils and replacing them with new R410a bespoke DX coils. Deep cleaning and repainting of the main frame work. Replacing belts, filters & locking nuts. Replacing inverter drives. Bearing kits for the fan motors/blades. The BEMS controls were updated with local controllers being installed within the plant room area, as well as a new Toshiba central controller being installed with the store maintenance office. All power wiring was renewed/upgraded as necessary. The AHUs were rebalanced and handed over all ahead of schedule. Schedule: 12 Week Project Project completed: 8 weeks SIMON REECE Store Manager Having major works completed during a busy trading period is always a concern. Steve and the team at Protec not only controlled the project and kept us fully informed during the regular review meetings, and they exceed all timescales by delivering 3 weeks early. Post-installation communication was excellent with Steve visiting regularly to maintain contact. An excellent job, well done! Thank You
- 3. 03 PROJECT: Debenhams Lincoln Project Value 贈350K The project involved replacing the existing R22 refrigerant system used in the majority of the air conditioning and cooling systems which served the store. The store is comprised of approximately 75,000 sq ft of retail space, spread over three floors; ground, first and second, with the main plant deck on the second floor roof level. We were required to replace 4 x 350kw packaged AHUs and back-of-house R22 VRF & split cassettes. We performed the duties of principal contractor for the whole R22 replacement project, which included sprinkler modifications and all necessary other building work. We were also responsible for liaising, where necessary, with store management, all statutory parties and landlords representatives to ensure all necessary approvals to work were obtained accordingly. There were a 4 packaged units located on the main deck second floor roof level and these serve the retail sales floor zones. Due to location of the AHUs, an early morning road closure of Lincoln High Street had to be carried out. Once we had positioned Europes largest mobile crane, it lifted the 3.5 ton AHUs weight to a height of 65m. We also had to organise 7 articulated lorries to be brought to the city centre to dispose of the existing units and bring in the new equipment. The existing units were approximately 17 years old and extreme care had to be taken while removing the AHUs, making sure support straps were positioned correctly, allowing the unit to be lifted off of the existing steel support without damaging the crane and the clients property. All work had to be exercised within a 10hr time period. The tolerances worked to whilst carrying out these works were less than 100mm. All relevant control circuits and electrical power wiring were renewed/upgraded as necessary. A re-balance of our air systems was carried out on all AHU systems. Cleaning of duct distribution systems serving the sales floor levels was completed out of hours. There was a total of 15 systems located on the roof plant deck. They all utilised either R410A or R22 refrigerant systems and served predominantly the back-of-house arears. Schedule: 10 Week Project Project completed: 6 weeks PAUL WADSWORTH Technical Director All the equipment was supplied by Huston (UK) Ltd. The installation contact for all this work was awarded to Protec Services Ltd against stiff commercial opposition. Protec then proceeded to work closely with Huston (UK) to ensure that all the equipment was supplied and install to the specification, without disruption to the store, to time scale and to the rigorous quality demanded. The installation was carried out very professionally extremely swiftly and to a very high standard of workmanship by Protecs team of installation engineers, led by Paul Osborn. The crane lift was carried out in the early hours of a Sunday morning by one of Europes largest mobile tower cranes, the road closure was kept to a minimum; this was down to Steve Macdonalds meticulous logistical planning. We look forward to working with Protec on future projects

- 5. 05 PROJECT: Upper Belgrave Street (Residential) Installation and commissioning of 1 x 30 kw Unico system into high end flat conversion. Appointed Air conditioning and controls contractor. Dale contracts and Ganter appointed us to supply them with a fully integrated heating cooling and heat recovery solution to this highly specified show flat. By using existing American kit and European condensers a high COP (coefficient of performance) was achieved on site. System utilised both heat pump and hot water supplies to achieve optimum space temperatures. Working with an international interior design team aesthetics are of very high importance, while still ensuring operational specifics are attained. PROJECT: 47 Homefield Road (Residential) Protec were the main contractors for this refurbishment installation. The residence had only recently been completed but the clients were unhappy with the constant high temperatures on the upper floors. Protec were appointed to rectify this with minimal disturbance or damage to existing decorations and ceilings. Work was carried out to install five wall mounts in all upstairs bedrooms and conceale all pipe and drain routes, including full redecoration of any building works. All necessary electrical installation certificates were issued and the base builder was employed to check installation and guarantees.
- 6. Project Value: 贈150k This project involved replacing the 2 x Toshiba 407C VRFs and 2 x 300kw R22 heat pumps which served the AHUs that supplied the sales floor arears within Boots Oracle, Reading. We were required to decommission the existing Toshiba VRF system based within the 3rd floor roof plant area, decommission and remove heat pumps that served the ground and first floor sales floor. Install 17 new Toshiba heat pumps to AHUs. We performed the duties of principal contractor for the whole of the replacement project which included associated works such as builders work in connection with the installation and all BMS works. We were also responsible for liaising, where necessary, with the store management and all statutory parties, landlords representatives to ensure all necessary approvals to work were obtained accordingly. Heat pumps and Coils were decommissioned and broken down so they could be manually handed off the roof due to crane restrictions. Bespoke DX coils were manually lifted to roof plant room and installed. Local controls were installed and all power wiring was renewed/ upgraded as necessary.
