Evaluation of a seasonal storage system of solar energy for house heating using different absorption couples
چکیده انگلیسی

In this paper, an innovative concept is presented for a long-term energy storage system for house heating, using the absorption process. The solar energy is stored during summer through desorption and the heat is released during winter through absorption. The originality of this concept is to allow the solution to reach the crystallization point, which is usually avoided in the absorption refrigeration machines. The storage capacity and efficiency of seven absorption couples, CaCl2/H2O, Glycerin/H2O, KOH/H2O, LiBr/H2O, LiCl/H2O, NaOH/H2O and H2O/NH3, as a function of the temperature of absorption, temperature of evaporation, temperature of the solution before absorption and the presence of crystals in the storage tank have been studied in this paper. The appearance of crystals increases the storage capacity. The storage capacity increases with the temperature of evaporation and the temperature of the solution before absorption but decreases with the temperature of absorption.

Research highlights
► An absorption system for long-term energy storage for house heating is presented.
► The storage capacity and efficiency of seven absorption couples are studied.
► The influence of temperature of absorption, evaporation and storage is evaluated.
► The appearance of crystals in the storage tank increases the storage capacity.
