A CHCP System Constituted by a Microturbine and an Exhaust Absorption Chiller.

The combined heat, cooling and power production (CHCP) is one of the most interesting methods to increase the system global efficiency by supplying electric and thermal power needs both in winter and in 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 produce cooling 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 “La Sapienza” (approximately 1000.000 cubic meter and an energy bill of some 10 M€) and it consists of a gas micro-turbine and a direct exhaust absorption chiller/heater, and will be realised in the area of Pharmacology 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”; the paper deals with the energy savings evaluation, both from the economical and environmental point of view.
