Problem
As part of a major expansion plan, the Daily Mail Newspaper Group plan to build up to fifty new local office centres around the UK. The first, in Truro, was to pioneer a chilled beam system that is both easier to install and maintain in a busy working office environment.
The contractor had specified the installation of around 100 passive chilled beams, each requiring a supply of water at a temperature of 14ºC, which returns back to a chiller. The flow levels of water to each group of beams needed to be balanced and controlled by a three port control valve.
Solution
Individual manifolds for each group of beams, equipped with an infra red flow measuring device, proved to be the answer.
Each pre-assembled manifold is fitted with a Marflow Filterball to protect the flow system and the return incorporates a Terminator balancing valve to measure the manifold design flow rate. Assembly is configured in a straight line to allow the system to be flushed more easily.
Says Paul Walters of design consultants Dog Cumming & Love: “This was the first time we had specified this type of system by Marflow. It was installed very quickly and we were impressed with its ease of measurement.”
Connection of the manifolds to the chilled beams is by PEXAL multi-layered pipe, the flexibility of which enables it to be handled almost like cabling. Made from a combination of plastic and aluminium, PEXAL has the attributes of both, i.e. light weight and insular with the rigidity of metal.
