Approved Dantherm contractors KVCayr in Scotland have been providing cost-efficient ventilation solutions for Citadel Leisure Centre’s swimming pool project.
The original Leisure Centre was built in 1972 with the pool hall, comprising of a main pool, teaching pool and flexi multipurpose pool. The existing ventilation was 100% fresh air supplied by two original Cyclone fans with the supply air initially heated by steam coils and then latterly by LTHW from the heating system.
The extract system comprised of a number of fans located in the roof void extracting the warm pool air to atmosphere. There was no recirculation, leading to a significant loss of heat that, with the right system, could be usefully reclaimed.
After a considerable amount of consultation with KVCayr a solution was found that would allow more than 75% of the rejected heat to be recycled and that would not disrupt the operation of the swimming pools during installation.
The unit would be located outside in a compound under a concrete canopy. This location avoided a great deal of complex and disruptive enabling works.
Funding was obtained using pre-existing government funding and a Dantherm DanX unit complete with heat recovery was installed.
A stipulation in the specification was that the heat recovery unit would provide an ‘open protocol’ controller on the unit to allow its integration with existing controls and let the performance of the unit be continuously monitored. Touchscreen technology makes it easy to adjust the operating parameters and match air flow to the buildings load requirements.
“The installation went ahead as planned and was completed on time with no disruption to pool users. Altogether a painless exercise” said Ian Hill, Senior Energy Officer, South Ayrshire Council.
“Savings were being demonstrated practically overnight, in the region of around £65,000 per annum across gas and electricity. Payback will be just over three years with a 20-year expected lifespan.”
