Keeping in view the increasing heat crisis in the world and the present scenario of difficulty to work in hot and humid conditions, a cutting-edge idea of a smart, innovative AC dress is required for workers in the field, medical professions, industries, education, and any area where comfort and efficiency are essential. This project presents the design and development of a wearable Air-Conditioning (AC) dress that provides personal cooling using thermoelectric technology. The system uses Peltier modules powered by a rechargeable battery and supported by renewable energy sources such as solar panels. The aim is to create a lightweight, portable, and energy-efficient cooling solution for use in hot climates. The proposed design focuses on comfort, safety, and practicality, making it suitable for daily use, industrial workers, and outdoor environments.
Introduction
With increasing global temperatures and frequent heat waves, people working in outdoor, industrial, healthcare, and field environments face significant thermal stress. Traditional air-conditioning systems are stationary and unsuitable for mobile work conditions. This research proposes a wearable smart cooling system that aims to:
Lower body temperature in hot environments.
Utilize solar energy for sustainable charging.
Improve user comfort and work productivity.
Provide a lightweight, portable, and wearable cooling solution.
Alternative Cooling Techniques Reviewed
The study examines several personal cooling methods:
Liquid Cooling: Uses chilled water circulating through garment tubing; effective but heavy due to pumps and water reservoirs.
Phase Change Materials (PCMs): Absorb heat during phase transitions; lightweight and passive but have limited cooling duration and require recharging.
Fan Ventilation: Uses small fans to enhance heat loss; lightweight and energy-efficient but less effective in humid conditions.
Thermoelectric (Peltier Effect): Generates a cold surface using electrical current, achieving temperatures 15–20°C below ambient. This method provides the best targeted cooling and is selected for the proposed system.
Proposed System Design
The wearable cooling system is based on the Peltier Effect, where electricity transfers heat from one side of a thermoelectric module to the other. The cold side cools the wearer, while the hot side dissipates heat through heat sinks and exhaust fans.
Main Components
Peltier module (TEC1-12706)
Cooling fan (12V DC)
Aluminum heat sink
Rechargeable 12V Li-ion battery
Solar panel for charging
Temperature controller
Switches and wiring
Breathable fabric
Insulation layer
Fabrication and Layout
A breathable garment is designed with pockets that hold the Peltier modules close to the skin. Heat sinks and fans are mounted externally to remove heat efficiently, while the battery pack is secured at the waist. The system includes airflow ducts, cooling zones, air outlets, exhaust vents, dual fans, and a control unit for temperature and speed adjustment.
Conclusion
The wearable AC dress is a promising innovation for personal cooling. It provides a portable, wearable, energy-efficient, and eco-friendly solution that addresses the growing challenge of heat stress in outdoor and industrial environments. With further improvements in battery technology, flexible thermoelectric modules, and adaptive control systems, it has the potential to become a practical and commercially viable product for daily use, industrial applications, and diverse fields of human activity.
