Description

Contact cold feeling instrument

Technical Field

The utility model relates to a test equipment technical field weaves especially relates to a contact cold detector.

Background

Fabric cold and warm feeling (or thermal comfort) is the judgment about cold and warm formed in the human brain by the temperature stimulus that the fabric gives to the skin after the fabric is in contact with the human skin. When the fabric is in contact with the skin, heat exchange occurs between the fabric and the skin due to the temperature difference, so that the temperature of the skin is increased or decreased. The heat exchange between the fabric and the skin is mainly heat conduction, and the influence of heat radiation and natural convection inside the fabric is small and negligible. In general (except for the fact that the ambient temperature is higher than the skin temperature), the skin temperature is higher than the ambient temperature, so that the skin temperature tends to decrease after the fabric is in contact with the skin, and if the amount of temperature decrease (or increase) exceeds a certain limit, discomfort can be caused.
