Résumé

Cold storage facilities are energy-intensive, particularly during summer months, increasing operational costs and grid dependence. This study evaluates the potential of an Earth–Air Heat Exchanger (EAHE) integrated with a vapor compression refrigeration system (VCRS) to improve energy efficiency under diverse Indian climatic conditions. An experimentally validated CFD-based model was used to assess EAHE-assisted condenser cooling and compared with a conventional air-cooled configuration across five representative locations. Results show that EAHE-assisted cooling significantly reduces compressor work during hotter months, with reductions of 7.5–16.8% depending on location. An adaptive cooling strategy, which selectively switches between air and EAHE cooling based on minimum compressor work, yielded SEER improvements of 3.7–6% without increasing cooling capacity or auxiliary energy consumption. Economic analysis revealed reasonably short payback periods (4.6–7.5 years) for inland regions with dry climates, while coastal locations exhibited longer payback (11.2–13.3 years) as coastal proximity leads to reduced seasonal ambient temperature fluctuations, diminishing the performance gains achievable through EAHE cooling. Overall, the proposed adaptive EAHE-integrated system offers a climatically suitable and scalable approach for improving cold storage efficiency in energy-constrained regions.
