Design of Subsurface Geothermal Cooling System of Greenhouse Farm

Global food security is a problem due to climate change and this calls for innovative agricultural strategies. The apparent actions like climatic variability and energy cost high geographic place in Lucban, Quezon a brief survey should be taken about the alternate source of energy and the so the searching of geothermal energy. The objective of this work will be to develop a distinct Geothermal Energy Cooling System for greenhouse farmingin this region.These goals are review to determine heating system requirements, create ideal layout, fabricate a prototype, and assess efficiency. To have a clear understanding of the requirements and the difficulties faced due to the heating system, distinct analytical methodologies such as fishbone, why-why, root-cause analyses were applied. Field observations, surveys, and experimental experiments were used as data collecting methods. The results indicated that the prototype was able to regulate greenhouse temperatures effectively, maintaining an overage cooling efficiency of 33.9% based on the conversion of mechanical to electrical power. The system showed significant potential in stabilizing internal greenhouse temperatures, which improved crop yield by up to 15% during trials. Additionally, energy consumption was reduced by 20% compared to conventional methods, demonstrating cost-efficiency and environmental benefits. Farmers surveyed reported improved control over greenhouse conditions, addressing challenges posed by climate variability. These findings underscore the prototype's feasibility in mitigating the adverse effects of climate change while promoting sustainable agriculture in Lucban, Quezon.
