Kansei EngineeringThe science of heat and thermal perception: Creating individually preferred thermal environments by adjusting airflow and clothingDivision of Textile and Kansei EngineeringHeating, ventilation, air-conditioning, and refrigeration (HVAC&R) systems consume energy. Since the thermal environment is an important factor in determining the productivity of occupants, it is desirable to develop effective HVAC&R systems. I am working to develop numerical simulation methods and experimental devices to analyze the thermophysiological state of the human body and the surrounding thermal environment. Simultaneously, I am developing new personal HVAC&R systems based on various methods and devices.Tomonori SakoiSenior Assistant ProfessorThis human subject experiment is being carried out to validate the cooling clothing that my lab developed. The clothing provided an adequate cooling eect, even in a warm and humid environment, when a convection fan was simultaneously used.Dr. Sakoi came to Shinshu University as an assistant professor after work experience at the University of Tokyo and the National Institute of Advanced Industrial Science and Technology, and he assumed his current position in 2013. He has won nine awards, including three “Best Paper” awards from the Society of Heating, Air-Conditioning and Sanitary Engineers of Japan (2001, 2004, and 2009) and one “Best Paper” award from ASHRAE HVAC&R Research (2014).Outlook for researchGraduates work for major homebuilders, insurance companies, part manufacturing companies, and textile development companies.Outlook for students after graduationKansei EngineeringAnalyzing clothing and textile products through computer simulationDivision of Textile and Kansei EngineeringI am engaged in research that uses computer simulation to replicate clothing and the human body and predict and analyze mechanical and thermal phenomena. By allowing visualization of phenomena that would otherwise be difficult to observe, simulation is expected to contribute greatly to the design and evaluation of clothing and textile products.Yosuke HoribaAssistant ProfessorSimulating pressure applied to clothing makes it possible to consider pressure distribution from motion at the design stage.By combining prediction of the distribution of body temperature and air temperature around the body with such indicators as the predicted mean vote (PMV), it will be possible to predict the thermal comfort of clothing.Assistant Professor Horiba, who holds a Doctorate of Engineering from the Shinshu University Graduate School of Engineering, took his current position in 2002. He is primarily involved in research in kansei engineering, computational mechanics, and clothing physiology.If we can clarify the relationships of the physical phenomena that occur between clothing and the body based on sensation, I believe it will be possible to predict the comfort of clothing.Outlook for researchMost graduates leverage their knowledge and experience in textile engineering, computational mechanics, and computer programming to secure employment in the textile and IT industries.Outlook for students after graduationThis device is used to determine the heat transfer characteristics of body segments in a non-uniform thermal environment.Numerical simulation is used to analyze air and body temperature distributions.17Based on the results of analysis of thermophysiological state and the surrounding environment, I intend to propose reasonable ways to form a comfortable microclimate around the human body, especially by adjusting clothing and airow. As an example, my lab has developed clothing with adjustable cooling capability that utilizes water evaporation.
