Evaluate the Cooling Effect of Cooling Garments: A Review

Abstract

Personal cooling garments have the advantages of being highly effective and economically practical, and are widely used in industry, medicine and aerospace. Personal cooling garments exhibit different cooling efficiencies and thermal comfort in different environments due to their different cooling medium characteristics. Air-cooling garments and liquid-cooling garments require the connection of external equipment when using, limiting the wearer’s range of motion. The use of phase change cooling garments is limited due to issues such as their large weight, short cooling time, limited cooling capacity, and susceptibility to supercooling during use. Hybrid-personal-cooling garments have a wide range of applications and may be accompanied by problems of supercooling injuries and high costs. The article reviews the cooling efficiency and comfort of personal cooling garments when different media through experimental summary method, comparative method and literature method.
