Volume 6 No.5 August | September 2020 NEWS 10 Skid-mounted solution gives installers a lift HOTEL GOES GREEN WITH WATER SOURCE North Yorkshire’s first five-star hotel has chosen a water source heat pump system from Stiebel Eltron to provide renewable energy across its estate as part of a £70m restoration project. The Grade II* listed property, which is in a conservation area, required a sustainable system which had no visual impact on the building or surrounding area, while providing reliable hot water to the hotel’s 47 guest bedrooms and hotel kitchens. The 520kW system installed by Pure Renewables is fed by a subterranean aquifier situated 90m below the surface. This means there are no visible flues required, minimising visual impact, while providing a constant supply of 14°C source temperature water. The system supplies 12,500ltr of hot water capacity for the hotel and heating through an extensive underfloor heating and radiator network. Toshiba Carrier UK (TCUK) has developed a skid-mounted version of its Floway air handling unit (AHU) and direct expansion (DX) condenser package, which it says allows installation in a single lift. The solution comprises a compact CIAT Floway Access AHU, incorporating a thermal wheel that claims more than 80% eciency, matched to a Toshiba digital inverter condensing unit, in a single package that comes fully wired, charged with refrigerant and commissioned ready for installation. TCUK installs interconnecting pipework in factory conditions and pressure tests every system before delivery to site, ensuring they arrive in perfect condition and operate properly. Controls are integrated into the package and come housed in a weather-proof enclosure. Available in five sizes, the skid-mounted systems deliver air flows of up to 2.36m3/ sec and come in capacities up to 46kW in reverse cycle cooling and heating. Aerofoil Energy ‘gifts’ Vortex Aerofoil Energy is gifting its suite of energy-saving Vortex refrigeration technology to UK supermarkets. Vortex works alongside the company’s Aerofoils to further increase energy eciency and improve the product temperatures of supermarket refrigeration. The technology has been developed in collaboration with technical partner Williams Advanced Engineering to improve the aerodynamic and thermodynamic performance of open-fronted fridges and covers some 20 patents. Already installed in fridges spanning over a thousand UK stores, Vortex is said to be particularly suitable for new-build fridges because it can be incorporated into the existing assembly process on a very low-cost or no-cost basis. Paul McAndrew, founder and CEO of Aerofoil Energy, said: “Our Aerofoil technology already saves 150,000 tonnes of CO2 every year in the UK alone but we know we can do more. We are gifting our suite of Vortex technology to speed up take-up across the grocery industry with the dual aims of reducing UK CO 2 emissions by 1 million tonnes per year and enabling supermarkets to commit and deliver on Net Zero targets.”
