Abstract

In this study, a geothermal cooling system is developed to address extreme heat conditions in regions like Nawabshah, Pakistan, by utilising the earth’s stable underground temperature. This system uses ground-source cooling, powered by a 12V solar PV system or battery, as a low-energy alternative for areas with a limited electricity supply. The experiment demonstrates that a geothermal cooling system could help redress indoor temperatures by up to 16°C during peak summer, resulting in a lower grid-connected or fossil fuel-based cooling system requirement. The results obtained through this study suggest a significant reduction in indoor temperature, ultimately enhancing comfort levels and reducing the reliance on conventional cooling systems like air conditioning. Moreover, the system design is easily adaptable to other regions with similar climates, highlighting its potential for widespread use. However, pipe configuration optimisation is needed to minimise costs and maximise heat transfer rate. This research emphasises geothermal technologies' potential as a cost-effective cooling system, ultimately reducing carbon emissions and improving energy efficiency.
