Abstract
A lumped parameter model of a domestic heat storage/recovery system is described. This is a typical green kitchen application, where the heat dissipated by kitchen appliances is stored in suitable materials by temperature rise and/or phase transitions. To this aim, sensible heat materials and phase change materials are considered. Based on the model, a number of design solutions are proposed, making use of fixed beds or shell-and-tube heat exchangers, where heat is stored in spheres or cylinders made up of (or encapsulating) suitable materials. The best solution (a PCM-based shell-and-tube exchanger) corresponds to ~50×50×25 cm, ~30 kg modules.
