摘要：Transport/storage box is to be used for storing the inorganic material under control environment. The main aim of this storage box is maintain the inside temperature during the transport in the production plant or customer place for the short duration of 1 to 2hrs. In general, during day or night times the interior temperature of storage box increases or decreases than the ambient temperature. This change in temperature can make the stored inorganic materials hazardous. A latent heat based storage system plays a major role in removing unwanted heat & maintaining the inside temperature of the storage box. Numerical and experimental studies were conducted to investigate the role of PCM in maintaining the temperature inside the wooden storage. Storage box is made by plywood and avoid the heat transfer from ambient. the sides and bottom walls are insulated by pasting the thermocol. Experimentation is carried out on the wooden box with no PCM and then with PCM. The operating conditions like solar radiation and ambient temperature is same for both the cases. PCM is placed horizontally on the Aluminium mesh, which is seated above the thermocol padding on top side. The experimental results showed that the box air temperature in the case of without PCM could be raised 42°C depending on how long the box is exposed to sunlight. In case of the wooden box with PCM the inside temperature of 37°C could be maintained for nearly one hour. Considering the same boundary conditions employed in experiments like sun radiation, ambient temperature, a 3D transient numerical simulation is carried out using ANSYS FLUENT. HYPERMESH is used for meshing the solid and fluid domain. Inside air and outside air is considered as fluid domain in the simulation. Both the experimental and numerical results were in variation with 1°C.
