Wythenshawe Forum
Detailed design of a cascade ASHP system with simultaneous heat recovery from existing chillers. RIBA 4-7.
LOCATION
Manchester, UK
DESIGNED TECHNOLOGY
350kW ASHP
Simultaneous Cascade
PROJECT OVERVIEW
Having been awarded SALIX funding to decarbonise the site, GeoEnergy were instructed by Manchester City Council to provide detailed design for an ASHP system to integrate with existing heat emitter circuits at Wythenshawe Forum, a multi-faceted community centre with a variety of heating and cooling systems. The heat pump system was to work alongside existing boilers and CHP, reducing their load and thus CO2 emissions of the site.
Having assessed the demands of the main heating distribution system, GeoEnergy proposed a cascade system to ensure required flow temperatures could be met. The chiller system serving the gym was an opportunity to recover valuable heat, currently being expelled to the environment. GeoEnergy recommended “closing the loop;” using a simultaneous ASHP to take the load off the chillers and supplement the heat extracted from outside air. This has been shown to dramatically reduce on site energy consumption and increase the performance of the heating system.
PROJECT DELIVERABLES
GeoEnergy have acted as client’s engineer to aid on the scheme, and have completed techno-economic analysis, planning, and concept drawings as well as thermal load and PV modelling. A full mechanical specification including detailed Ground Loop Design has also been completed, with a tender pack issued to contractors. The project is to commence as soon as planning permission for the PV system is granted.
