Résumé

This article studies, experimentally and theoretically, the thermal performance of cold storage using a thermal battery for air conditioning. The thermal battery utilizes the superior heat transfer characteristics of heat pipes and eliminates drawbacks found in the conventional thermal storage tank. Experimental investigations were first conducted to study the cold storage thermal performance in two experimental systems: the ratio of the distance between heat pipes to the outer diameter of the heat pipe W/D=6 and 2. Different heat transfer mechanisms, including nucleate boiling, geyser boiling and natural convection, were identified in different experimental systems with various liquid fills. A theoretical model to determine the thermal characteristics of the thermal battery were also developed. Comparisons of this theory with experimental data show good agreement in the nucleate boiling stage of the cold storage process.
