Summary

The purpose of this study is to investigate the thermal effects of contact on human thermal sensation, particularly focusing on discontinuous contact. On account of the Japanese lifestyle of not wearing shoes in residential houses, it is desirable to estimate the thermal effects of contact with the floor. In order to investigate the relationship between human thermal sensation and contact factors, such as floor contact temperature and the amount of contact heat loss, subjective tests and measurements with an artificial foot were carried out in a climate chamber. Two contact patterns, continuous and discontinuous contact, were used in these experiments. The experiments were conducted for two different steady ambient temperatures: 30°C for summer conditions and 20°C for winter conditions. In addition, a floor heating system was used only in the winter experiment. As a result, it was found that discontinuous contact raises the amount of contact heat loss, especially when a floor heating system is not being used. Furthermore, human thermal sensation tends to be cooler as the amount of contact heat loss increases. In conclusion, discontinuous contact effectively cools the human body. However, this effect can be reduced by employing a heat source such as an underfloor heating system.
