MBS Aermec raises the bar in fan coil design The launch of Aermec innovative VEC-i fan coil unit (FCU) heralds the next generation of cassette systems. The VEC-I works smarter by combining efficiencies with significant reductions in embodied carbon. The VEC-i fan coil is a cassette- type unit with a difference, featuring integrated diffusers delivering air straight into the room so that the jets of air adhere to the ceiling, creating a Coanda effect and a draught-free environment. The VEC-i offers exceptional energy savings and addresses the need to reduce embodied carbon whilst providing end-users with stylish units that provide total comfort. Aermec carried out extensive modelling. Based on a 15-year period of operation and using CIBSE’s methodology, calculated that the VEC-i represents only 18% of total embodied carbon (KgCO2e) confirming that focusing on product weight is a key variable. Aermec has consistently pushed the boundaries in product design and development, the VEC-i is no exception, it is aesthetically attractive and is suitable for a wide range of projects. www.aermec.co.uk Daikin Applied launches larger capacity water-cooled chillers Daikin Applied has further extended its range of chillers with the introduction of the DWDC C series of centrifugal compressor water- cooledmodels. Available in a choice of cooling capacities between 1,500 and 2,500kW, the range has been developed to optimize energy efficiency and reduce operating costs. The new chillers are designed for use with low global warming refrigerants R-134a, R-513A, or R-1234ze in a single refrigerant circuit and are suitable for commercial cooling, district energy plants, and manufacturing applications. The dual compressor design delivers impressive part-load efficiency along with system redundancy comparable to operating two separate chillers, but with a much lower total installed cost. The DWDC C can also be equipped with variable speed drives for additional efficiency. The DWDC C range is also available with conventional refrigerants R-134a and R-513A, which will also remain available for use throughout the installed life of these chillers. This is in line with Daikin Applied’s philosophy of offering diverse refrigerant choices that mean the best-suited solution can be used for each application. It has expertise in the use of fluorinated gases (HFC, HFO) as well as non-fluorinated gases (ammonia, carbon dioxide, hydrocarbons). www.daikinapplied.uk
