Experimental Study of Solar Cold Energy Storage with Additional PCM and Without PCM

This Increased energy efficiency and comfort conditions in the building environment are increasingly needed. Therefore, phase change materials (PCM) are devoted to reducing the energy consumption of buildings. This research is an experiment with a solar-powered CES working system with dimensions of 740 mm × 410 mm × 310 mm which is used to supply cold air to a room with dimensions of 4.8 m × 3.7 m × 3.3 m. The main component of the CES cooling system consists of a combination of a thermoelectric system and an actively applied PCM. In active applications, forced convection is the dominant heat transfer mechanism between PCM and air in CES where some additional electrical devices are required. In this test, the results of CES without PCM were obtained, on the first and second days there were differences in the outlet temperature for the room and the inlet temperature for the room which were almost the same with an average of 1.43°C and 1.5°C. While CES with PCM on the first and second days with an average of 7.36°C and 3.85°C. For COP values obtained CES without PCM on the first and second days has an average value of 0.25. While the value of COP CES with PCM on the first and second days was 0.39 and 0.33.
