Full heating-cooling autonomy at 5 offices of NTUA

Five offices at the Laboratory of Steam Boilers and Thermal Plants at the School of Mechanical Engineering - NTUA now cover their entire heating/cooling demands from the ZEOSOL system, as a result of ZEOSOL project which was just successfully carried out (May 2020).

 

"The ZEOSOL project", was coordinated by NTUA, School of Mechanical Engineering, with Prof. Sotirios Karellas as project coordinator and PhD Cand. Tryfonas Roumpedakis as project engineer and main researcher. The project aimed at the development of a new advanced solar cooling and heating product, using advanced heat exchanger technology and integrating a heat pump for covering peak demand. Within this context, a demo solar adsorption cooling/heating setup was installed and experimentally tested with great success at one of the buildings of the School of Mechanical Engineering and more specifically at the Laboratory of Steam Boilers and Thermal Plants.

 

ZEOSOL System Life Cycle Analysis

The ZEOSOL system life cycle analysis was developed to evaluate the system's environmental impact, a study conducted by Dipl. Ing. George Kallis. According to ISO definition, Life Cycle Analysis is a systematic and analytical method that helps identify, assess and minimize the environmental impact associated with a product's entire life cycle.

The results of the analysis highlight the importance of the electricity savings, mainly in categories such as global warming, ozone depletion and water use. On the other hand, system components of high copper content, with the solar field to be the main contributor, deteriorate the system's performance in the impact categories of land use and mineral resources scarcity.

 

Compared to a conventional heat pump, the ZEOSOL system has significantly better performance in areas of global warming and ozone depletion due to the significant reduction in electrical power dependence. On the contrary, ZEOSOL's behavior is worse in the use of copper and other minerals, where a heat pump has only 20% of ZEOSOL's environmental impact. As for the location of the system, it is noted that it has a significant impact on the overall system's environmental performance, with the electricity production mixture of each country to be a critical factor per case.
