Chilled Beams 27 y and the CBCA
of high output beams as ‘high efficiency’ to reduce overall project quantity/linear meters of active beam, designers should be mindful of guide lines for occupancy comfort (ISO 7730) when using as ‘high output’.
CBCA
return temperatures to the chilled beam units with the relationship between water flow temperature and chiller coefficient of performance (COP) as modelled.
Recent advances in chilled beam design have provided ‘high performance beams’. These could be used as ‘high efficiency’ beams by keeping the same linear meters/quantity of units on project designs as traditionally associated, but elevated water temperatures a few degrees centigrade above the industry standard of 14°C flow significantly reduces energy consumption as proven during this energy study.
For every 1°C above the industry chilled beam standard of 14°C flow it potentially reduces around 3% to 4% on the overall system energy consumption.
However, if capital cost reduction is the driver, rather than energy reduction, the use
The main aim of the CBCA is to help educate project stakeholders so that they can make more informed considerations.
It is our strong belief that chilled beam technology is a viable alternative and often should be the first choice. Hopefully this EDSL report and our ongoing drive for relevant and factual information in the market will enhance the decision making process.
We welcome the debate the report is creating as these findings mean the market can now ascertain for itself the conclusions that can be drawn from this study.
The findings of this research come at a time when energy demand and supply is top of the news agenda, and as the impact of the UK’s energy capacity gap is being examined both by policy makers and commercial and public property owners.
As an industry it is important we share knowledge to help design or refurbish buildings to perform more efficiently.
Our strength is our fast response
