Optimizing energy conservation of central heating systems based on temperature stratified water tank

Abstract

In this paper, the central heating system is taken as the main research object. The finite volume method was used to optimize the number of internal partitions, the height of the partitions, and the position of the partitions in the hot water storage water tank. The influence of temperature stratified water tank with optimized structure and fully mixed water tank on the central heating system is also analyzed. The results show that the temperature stratified water tank is more energy efficient in heating than the fully mixed water tank. The study enriches the relevant part of energy storage in central heating systems and is of guidance for heating engineering projects.
