Efficacité du Stockage Thermique par Chaleur Latente Expérimentation et Application à des Systèmes Energétiques réel

Abstract

The work done in this thesis is generally dedicated to reduce the energy consumption of buildings while ensuring the energy efficiency of housing and thermal comfort of the residents. We are interested in integrating PCM materials (Phase Change Materials) inside the housing, cold cell, and home bath heater (ECS). Integration of MCPs into walls and ceilings can be an effective solution. The influence of this passive concept (MCP + insulation) on heating and air conditioning is important because it favors a reduction of about 65.9%. On the other hand, incorporating MCP into cold cell walls can reduce annual energy consumed by up to 12.88%. Moreover, for water heating systems, particularly those equipped with latent tanks (MCP), it has been found expedient to maintain higher temperatures for better production. The hot water production will be greatly increased by increasing the temperature of the thermostat. By increasing the water temperature from 50 to 75 °C, a financial saving of approximately 47.42% was achieved. In fact, the obtained results prove that MCPs offer reliable and useful solutions for various applications.
