Abstract: In order to enhance the life safety and combat capability of firefighters, and with the continuous deepening of research on high-efficiency refrigeration related technologies, research on new personal cooling equipment is constantly advancing. This article mainly summarizes the classification, basic concepts, cooling principles, and advantages and disadvantages of passive and active personal cooling equipment in practical applications. It also looks forward to the future development trends of personal cooling equipment from three directions: comfort quantification design, functional and intelligent composite, and integrated quantification evaluation. This provides a basis for the research and application of personal cooling equipment.

Key words: personal cooling equipment, passive cooling equipment, active personal cooling equipment
