3 Solar-Assisted Absorption Cooling for Distributed Tri-Generation: A Case Study

Marija Todorovic, P.Eng., University of Belgrade
Gas fuelled tri-generation system is optimized by implementing solar assisted absorption cooling, heat recovery, thermal energy storage using ice; building's - thermal mass control via PCM, energy efficient lighting and daylighting control. Several packages of energy efficiency improvement measures are analysed, with the reference to the total installed power, cooling and heating energy demand, annual electricity and total energy demand, different control algorithms, as well as related investment and operational costs. It has been shown that, even for low gas prices and modest increase of electricity prices in the region, the optimal tri-generation system encompasses the solar assisted absorption cooling.
