Objective: This study developed working clothes using a vortex tube device to reduce the thermal stress of greenhouse workers, and evaluated the physiological effects and user satisfaction of the developed cooling vest.
Background: During the summer, the inside of greenhouses causes increased physiological burden of workers due to a high temperature and humidity, causing accidents and lowering the work efficiency. As a measure to solve this problem, various working clothes to lower thermal stress have been researched and developed, but there were limitations in the development of working clothes appropriate for high temperature and humidity in greenhouses. Therefore, the development of a new agricultural working clothes is required to prevent thermal stress of workers in a warm environment.
Method: To verify the thermal stress reduction effect of the farming vest applying a vortex tube device, a physiological evaluation test was performed for subjects in a climate chamber and greenhouse environment. In addition, the wearing satisfaction and field applicability of the developed working clothes was evaluated by farmers.
Results: The results of analyzing the mean physiological reactions by body part in the climate chamber test, the skin temperature, mean temperature in the working clothes, mean humidity, and heartrate of the developed working clothes decreased by 2.9%, 8.1%, 35.5%, and 4.9%, respectively, compared to the existing working clothes. Furthermore, in the greenhouse environment test, the temperature in the working clothes and humidity of the developed working clothes decreased by 8.8% and 12.3%, respectively, compared to the existing working clothes. Furthermore, in wearing sense and user satisfaction survey for farmers in the field evaluation, the respondents showed positive responses.
Conclusion: This study verified the effects of the agricultural working clothes applying the vortex tube technology had an effect of thermal stress reduction compared to the existing working clothes and its applicability to the agricultural work environment. Further practical research should be conducted considering the cultivation environment and the size of greenhouse facilities to develop working clothes for various work environments.
Application: The results of this study are expected to be utilizable in the field of design of thermal stress reducing working clothes for greenhouse facility farm workers.
