Analysis of Characteristics of Multi-Tank-Combined Heat Storage Water Tank : The Second Report-Understanding of Characteristics of Parallel Stratified Heat Storage Tank and Assessment of Adverse Effects of Malfunctions of Combined Fully-mixed Heat Storage Tank

Abstract

The authors have improved the test equipment of the multi-tank-combined water heat storage tank, which was earlier mentioned in the first report, for the purpose of facilitating tests of the parallel stratified heat storage tank. Using this experimental equipment, the authors have conducted tests in accordance with the varied flow distribution in each of the two parallel systems with a view to finding characteristics of inside temperatures of the heat storage tank. In light of the operating methods of air-conditioning systems, the authors have conducted tests additionally based on such factors that might have an impact on the heat storage efficiency of the combined fully-mixed heat storage tank as the diameter and placement of connecting pipes, gaps in secondary circular temperatures, drain pipes and residual heat storage volume in order to discover thermal characteristics of the heat storage tank.
