The global demand for air conditioning is projected to triple by 2050, making it one of the largest consumers of electrical energy in many regions. This surge in energy consumption poses challenges for sustainability and contributes to environmental strain, necessitating innovative alternatives to traditional air conditioning systems.

This invention introduces a smart air cooler designed to address these challenges by utilizing recycled materials, including used tyres, plywood, a fan, and a cooling device. By repurposing these components, the smart air cooler aims to provide an effective cooling solution while reducing environmental problems in daily life.

The assembly process begins with sourcing a used tyre from a car tyre mechanic shop. The tyre is thoroughly cleaned inside and out with water. Plywood is cut into round shapes to match the tyre’s diameter, glued around the edges, and attached to the front and back of the tyre. Small holes are drilled into the front of the tyre, a cooling box is fixed inside, and a fan is mounted at the back, completing the smart air cooler.

Users, particularly pupils, have reported feeling comfortable using the smart eco-air cooler box. A survey conducted via Google Forms with 24 respondents indicates positive customer feedback. The survey included six questions, each rated from 1 (poor) to 5 (excellent), assessing the cooler’s performance. Table 1 and Figure 3 demonstrate that students effectively used the smart air cooler, highlighting its ability to address daily cooling needs.

The smart air cooler box is simple, made from low-cost materials, and offers significant environmental benefits. By recycling used tyres and other materials, it helps reduce pollution and supports sustainable practices. This invention aligns with Sustainable Development Goal 13 (SDG13) by contributing to climate change mitigation through eco-friendly cooling solutions.
