Abstract:
Thermochemical heat storage is promising energy saving technology. In order to make the technology competitive it is necessary to identify all possible “bottle necks” of the heat transformation process. Three key modes of the heat release are considered: maximum power, maximum heating, prolonged heat release. Possible limiting stages of heat release are analyzed. Theoretical dependences describing released power and heat transfer fluid temperature are derived and verified experimentally. The global heat transfer coefficient UA and maximum power for small heat exchanger (140 cm3) were found by different methods. Results for UA (39 ± 4 W/K, 34 ± 4 W/K and 37 ± 4 W/K) and maximum power (320 ± 20 W and 350 ± 20 W) obtained theoretically and experimentally are in good agreement. Recommendations on realization of all three modes are given. The novelty of this paper is the attempt to perform a quantitative comprehensive analysis of the constraints that different system resistances impose on the released power.
