Development of a new testing protocol to evaluate cooling systems

Area of Science:

• Textile Science
• Human Physiology
• Thermal Engineering

Background:

• Thermal comfort, the sensation of thermal well-being, is crucial for user comfort and performance.
• Extreme environmental conditions can disrupt thermal balance, necessitating interventions like smart garments.
• Current evaluation methods for cooling vests (ASTM F2371-16, ASTM F2300-10) have limitations in terms of simplicity, objectivity, or affordability.

Purpose of the Study:

• To develop a new, simple, objective, and affordable testing method for evaluating the thermal performance of cooling vests.
• To integrate a thermal manikin with simulation software for enhanced testing capabilities.
• To study physiological parameters indicative of thermal comfort within a simulated human subject.

Main Methods:

• Development of a novel testing apparatus combining a thermal manikin with advanced simulation software.
• Utilizing the thermal manikin to simulate a human subject's physiological responses to heat stress.
• Incorporating simulation software to analyze and interpret physiological data collected from the manikin.

Main Results:

• The developed method provides a viable alternative for assessing thermal comfort and the efficacy of cooling garments.
• The combined thermal manikin and simulation approach allows for objective measurement of physiological parameters.
• The new method addresses the need for more accessible and reliable performance evaluations of personal protective equipment.

Conclusions:

• The novel testing method offers a promising solution for evaluating the thermal performance of smart garments like cooling vests.
• This approach enhances the objectivity and affordability of thermal comfort assessments in textile research.
• Further validation and application of this method can improve the design and effectiveness of heat stress mitigation technologies.
