The first presentation led by George Atkinson of the University of Warwick will focus on heat pump research and next-generation ammonia heat pump cycles. It will look at the problem facing domestic heating and how ammonia sorption cycles, which are used in gas-fired heat pumps, can offer a partial solution in the decarbonisation of domestic heating.

Sustainability will be at the heart of the second and third presentation as well. Henrique Lagoeiro of the London South Bank University will be presenting the Bunhill Heat Network,  a pioneering system that recovers waste heat from ventilation air from the London Underground and uses it to supply a heat network for heating buildings in the London Borough of Islington. A heat pump is utilised to upgrade the recovered heat before delivering it to the local district heating network, providing the potential to achieve significant carbon savings compared with fossil-fuel based heating systems.

Matt Wegner also from London South Bank University will be discussing the benefits of cooling with heat recovery for electrical cable tunnels and data centres with a study investigating the effect and impact of heat recovery on cable tunnels. The work combines technical and economic calculations together with measured data from a case study and shows significant benefits with wide-scale replication potential.
