A CHCP System Constituted by Microturbine and Exhaust Absorption Chiller

The combined heat, cooling and power production (CHCP) is one of the most interesting methods toincrease the system global efficiency by supplying electric and thermal power needs both in winter andin summer, and at the same time reducing CO2 emissions.Global efficiency increase is related to the use of waste heat which can be also used to producecooling energy by means of a absorption chillers.A CHCP programme is planned in a specific area in the University City of the University of Rome LaSapienza (approximately 1000.000 cubic meter and an energy bill of some 10 M) and it consists of agas micro-turbine and a direct exhaust absorption chiller/heater, and will be realised in the area ofPharmacology Institute buildings, being the first example in Italy.The realization is the first step which will be further implemented in other areas of University City; thepaper deals with the energy savings evaluation, both from the economical and environmental point ofview.
