Solar ventilation system using PVC ducts and PE mesh for the mitigation of thermal stress in a nursery in Arequipa-Perú Universidad Tecnológica del Perú (UTP), Av. Tacna y Arica 160, Arequipa-Perú Heat stress in nurseries poses a significant risk to worker health and productivity, particularly in high solar radiation regions such as Arequipa. In this context, this study developed the design of a low-cost forced ventilation system, powered by solar energy and constructed using polyvinyl chloride (PVC) sleeves lined with polyethylene (PE) mesh. The objective was to mitigate heat stress and ensure compliance with Peruvian regulation R.M. N° 375-2008-TR. Methodologically, the research comprised monitoring internal thermal conditions according to ISO 7243:2017, analyzing worker stress indicators, and designing the system via 3D modeling in Blender software. The obtained results revealed that the monitored points exceeded the permissible limits for the Wet Bulb Globe Temperature (WBGT) under the cited Peruvian standard, with critical values reaching up to 43.70°C. However, the proposed design demonstrated the capacity to reduce the WBGT by 8-10°C, homogenizing the thermal environment and ensuring compliance with national regulatory framework. It is concluded that this system represents a viable and scalable solution for improving working conditions in nurseries. | |
