Latent heat storage is an efficient energy storage method. In this study, a system was designed to store cold energy by producing ice in the refrigerated cabinet of a refrigeration system and to store hot energy by melting paraffin using the waste heat from the condenser. Extended surfaces were designed from waste materials to increase the thermal conductivity of paraffin, and ice storage modules were produced using a 3D printer for ice storage. A fuzzy logic-based control algorithm was developed to control the temperatures of paraffin and ice. The conventional system with a constant fan speed was compared to the fuzzy logic controlled system. According to the results obtained, in the fuzzy logic controlled experiment, paraffin and ice reached the target temperatures approximately 30.58% faster than in the conventionally controlled system, and energy consumption per cycle in the fuzzy logic controlled system decreased by 30.58% compared to the conventional system. In the proposed system, real-time and adaptive decision-making capabilities based on temperature profiles and cycle dynamics have resulted in a 40% increase in storage efficiency and a 24.7% reduction in payback period. Using the developed method, the desired temperatures were achieved in paraffin and ice, charging/discharging times were shortened compared to the traditional method, and energy consumption was reduced while storing the same amount of energy in a shorter time.
