Presented at: Heat Powered Cycles Conference, Newcastle upon Tyne, UK, 11-14 september 2006.

The SOCOOL project focuses on the development of a small-scale combined cold, heat and power (tri-generation) system, which utilises the engine waste heat for cold production. It is demonstrated at the CRF Eco-Canteen in Turin, Italy. The cooling machine is made of two separate sub-cooling systems, each of which is to produce 5 kW of cooling power. One of the cooling systems is driven by ‘low-temperature’ engine cooling water, the other by ‘high-temperature’ engine exhaust gases. Tri-generation systems that use heat-driven cooling, offer the possibility of saving 15-20% primary energy. The low-temperature-driven sorption-cooling machine was designed and built at ECN, The Netherlands. Its performance was tested in our own laboratories, before shipment to Turin where it was integrated with the internal combustion engine.
