Abstract
Trigeneration allows the thermal energy that is recovered from the prime mover of a cogeneration plant to be exploited to produce a cooling effect. In this way, when residential applications are considered, it is possible to extend the working hours of the plant over the heating period, providing the summer air conditioning. The paper is aimed at investigating the energetic performance of trigeneration, compared to cogeneration, dealing with the differences on prime mover efficiencies in the winter and the summer season. Two small-scale trigeneration plants have been considered: an internal combustion engine cogenerator capable of 126 kWel coupled to a liquid desiccant system, and a 100 kWel natural gas microturbine with an absorption chiller. The primary energy savings have been calculated, for both plant configurations, through a commonly accepted methodology proposed by the European Union, and through another methodology, reported in literature, which seems more appropriate to describe the energetic performances of trigeneration plants. A new performance indicator was then introduced by the Authors. The results are presented and discussed.Pubblicazioni consigliate
