Due to fluctuations in thermal load, CHP for offices needs careful design. Therefore SAV always offers to check expected site load patterns, to ensure satisfactory sizing and running hours by a LoadTracker installation.
FloCon HVAC Distribution Manifolds
FloCon commissioning modules act as flow distribution hubs. They simplify distribution arrangements to terminal units such as FCUs, chilled beams, trench heaters and radiant panels. They are compact and help to shorten install times.
Modules are often supplied in pre-insulated boxes, which means that insulation of individual items is not required. All parts are easily accessible. When it comes to flow balancing, the average FloCon installation needs only one quarter of the effort required by a traditional, individually piped layout.
Where it is not possible to serve clusters of terminal units from a central hub, Monolink valve arrangements can be used instead. Each terminal unit can then be easily flushed, cleaned and adjusted.
Energy meters and associated monitoring help to meet the requirements of CIBSE TM39 (Energy Sub-Metering in Buildings). Simple, robust, ultrasonic energy meters can be installed so as to monitor energy usage within sectors of a building. SAV Kamstrup meters maintain accuracy of measurement over prolonged service, and can provide the data for inclusion in Building Log Books, as referred to under Part L of Building Regulations.
DHW & BCW Manifolds, Valves & Fittings
The image shows the application of cooling manifolds and fittings to a City dealing room. The 50mm bore assembly is made up of segmented manifolds with integral isolators. A full bore bypass helps with the effective flushing of debris. Flexible multilayer Haka piping (coloured white) is shown between the manifold and terminal units. Haka contains an internal aluminium layer which serves as an oxygen barrier. It is easy to lay, simple to terminate and has a service life of over 50 years.
