Abstract

The results of numerical studies aimed to evaluate the heat capacity of short-term phase change heat accumulators applied in passive solar heating systems (PSHS) with a three-layer energy active translucent enclosure (TE) are presented. An example is given of calculation of specific (per unit of TE surface area) weight of heat accumulator using dimethyl sulfoxide, (СН₃)₂SO, with melting temperature 18.6°C and latent heat of phase transition 173 kJ/kg, as the heat storage agent.
