Effect of tube bundle arrangement on performance of shell-and-tube latent heat storage system

This work presents the results of experimental investigation on charging and discharging of latent heat storage systems (LHSS) in the form of shell-and-tube heat exchangers with a variable arrays of the tube bundles. The tests included two tube arrangements – in-line and triangular (staggered), a variable number of tubes in a bundle, two pitch ratios, and different tube positions in a bundle. Three commercial products (LTP56, RT54HC, P1808) from the group of aliphatic hydrocarbons were used as PCM. Systematic experimental studies have shown that regardless of the type of the tested PCM, the shortest charging / discharging rates for the tested LHSS were achieved for a bundle of 7 tubes in a staggered arrangement and a pitch ratio of 4.5.
