Abstract
Using a simple experimental layout, some tests on the behavior of a phase change material (PCM) were accomplished. To do this, a system using thermal oil as the heat transfer carrier was used and the phase change material being tested was kept inside a steel capsule with 190 mm length, 42 mm internal diameter and 48 mm external diameter. The heat transfer oil transferred heat to the PCM during the energy accumulation step and carried heat away from the PCM during the energy extracting step. The tested PCM was supplied by PCM Products Limited. This PCM, with the commercial name of PlusICE A164 is a sugar alcohol blend and has a fusion temperature of 164 °C. The influence of the mass flow rate of the heat transfer fluid, as well as of its inlet temperature, in the response of the phase change material, was studied. Two layouts of the capsule inside the testing heat exchanger were studied, a vertical and a transversal positioning Temperature profiles inside the phase change material contained in the capsule were obtained during the experiments.
