Project: Trigeneration Solar System with Thermal Energy Storage for On-demand Solar Trigeneration with acronym TES4TRIG
Partners: NTUA Laboratory of Steam Engines and Boilers (Coordinator), NSEFE Demokritos, MES Energy S.A., Aachen University of Applied Sciences Solar-Institut Jülich, CADE Soluciones de Ingeniería, S.L., Protarget AG.
The project aims to develop an innovative trigeneration system powered by solar parabolic collectors, based on the combination of an Organic Rankine Cycle (ORC) and an Ejector Cooling Cycle (ECC) with a cost-effective heat storage system. The Pilot installation and operation is taking place in the Administration Building at the Lavrio Technological and NTUA Lavrion Technological and Cultural Park.
In the context of its role, MES Energy SA implemented the following:
- Processing of technical data and energy analysis of the pilot building for the calculation of energy efficiency and thermal/cooling loads
- Contributing to the development of the system’s operating strategies to meet the energy needs of the building
- Dynamic energy simulation of the building using EnergyPlus software for optimal system sizing in the pilot building
- Extensive parametric analysis based on the dynamic energy simulation model to determine the cost-optimal implementation of the tri-generation system in various typologies of Greek buildings, according to the European Regulation 244/2012/EU.
Part of the results of the actions of MES Energy SA have been published in the paper:
