Abstract

The storage of latent heat, one of the thermal energy storage systems (TESs), is now used in cold storage applications. PCM's use in the refrigeration industry has been integrated into systems without mechanical chiller, as stated in the literature. In this case, PCMs play a promising role in increasing the performance of cooling systems and refrigeration applications. The aim of the present study is to determine energy consumption changes and without PCMs. The temperature of the cold storage and PCM were investigated and the on-off times of the compressor were also analyzed experimentally. Furthermore, the on/off period times of the cold storage were analyzed for the cold store without PCM. The results indicated that off period time increased, while working period time increased, significantly. PCM application provided a total energy efficiency increase of 20-22%. In addition, the phase change materials used as insulation material have a wide range of working temperatures, which has created another positive effect of the study.
