Abstract
| The heat storage based on the latent heat associated with the change in phase of material offers many advantages over sensible heat storage. The most important characteristic of such subsystem is its sufficient storage capacity. The phase change material behavior is visualized by constructing an idealized model of thermal capacitor, subjected to simulated solar system environmental conditions which include thermal cycling utilizing the heat of paraffin for heating and cooling. The whole structure assumed to be insulated to minimize heat loss. An analysis of the model is conducted using Goodman technique to generate data about the temperature distribution. The melt thickness, and heat stored in the phase change material for constant mass flow rate tests at various water inlet temperature. |
