Abstract

There exists a return piping in solar combi-system for heating and hot water supply. When the temperature of water returning from the load is mixed with the lower side cold water of the storage tank, useful energy is reduced. This paper describes a diffuser and manifold for preventing this mixing and maintaining temperature stratification. Results from experiments show that manifold holes are optimum at 8.5 mm in diameter with a total of 96 in number of holes at a flow rate of 0.3 lpm.
