ARC Control Systems were selected to provide the BMS and controls for Islington council’s ground breaking district heating project. The District Heating (DH) network serves over 800 homes, 2 leisure centres and 4 office blocks.
Heat is produced by a gas driven Combined Heat and Power (CHP) engine and distributed around the 2km DH network to serve the properties through plate heat exchangers which transfer heat to the building’s local heating system. Heat from the CHP is stored locally in a 115 cubic metre thermal store to optimise operation of the CHP and provide a buffer of heat to help with peak demands.
A Trend BMS controls the operation of the CHP and DH pumps as well as the plate heat exchangers which are connected by a fiber-optic communication network.
Energy meters log heat output from the CHP and also energy usage data at the plate heat exchangers which is utilised by the BMS to determine system demand.
ARC Control Systems are pleased to be involved with the next phase of this exciting project which will utilise excess heat from the London Underground and convert it into hot water for the DH network which will be expanded to a further 450 homes.
