Andrew Sargent, general manager of Advanced Air, examines the chilled beam market and the impact that a new generation of energy efficient ec fan coils could have on the demand for these systems. Unlike a traditional fancoil with a fan a chilled beam doesn’t require a fan. as they have no moving parts to them. This started to have a significant influence on the type of system chosen. After energy, capital cost is probably the next most important issue (in fact in many cases this is incorrectly put ahead of the energy argument). Horizontal concealed units were considered, installed in false ceilings, supplied with 100% fresh air through an AHU. Since 2008 EC Motors have become a popular option with fan coil units and research at Advanced Air has shown that a Specific Fan Power (SFP) of 0.15w/l/s can be achieved, reducing the carbon emissions by a figure approaching six times that for a conventional AC fan coil unit. w.c. (75 Pa to 300 Pa) at the pressurization plenum of the beam. With a simple chilled beam mounted in the ceiling, other costs over and above the product will be installation, piping, ducting, controls and electrical works. Due to negative buoyancy, this air falls into the space. In the UK they have been extensively used and are the preferred system for many major developers and consultants. The EC report on climatic ceilings and chilled beams points out that the UK is almost alone in northern Europe in continuing to prefer fan coils. Webinars The value to the manufacturer of fully-integrated multi-service chilled beams with all of the services installed could be as much as eight times compared to a standard fan coil unit. Supplier directory Since large buildings require large amounts of energy to keep cool, the idea of a chilled beam system is to use natural convection (warm air rises, cool air falls) and the superior energy capacity of water to make cooling much more economical. Now that has been all but neutralised the issues mentioned above will come into play. Wall-mounted ductless or fan-coil … The desiccant dehumidifier for use in Lithium-ion Battery Production has won Sustainable Product of the Year in the HVR Awards 2020. With any forecast or predication it is always worth studying what’s happened in the past since invariably this will give a clue as to how things will develop in the future. Chilled beams had lower carbon emissions than fan coils and this was a driver due to the impact of the then new building regulations. Introduction to Chilled Beams A chilled beam is an air distribution device with an integral coil that may be installed within a space in order to provide sensible cooling and heating. These units fit in a drop ceiling or can be hung flush to the ceiling and contain a chilled/hot water coil and, in the case of active beams, a duct bringing in ventilation air. It compares the energy consumption, CO2 emissions and running costs of passive and active chilled beams with VAV fan coils utilising EC motors. In an active chilled beam, an induction unit forces air over the coil while the natural convection in the room is also occurring, forcing the hot air up. 36IBAN - 1-Way Discharge Narrow. Chilled beams have a range of advantages: • Chilled beams have no terminal unit fan, so overall system fan energy is lower when compared to the other systems requiring terminal equipment fans (four-pipe fan coil unit, DOAS, fan-powered VAV).
