A Proposal on Safe Temperature of Floor Surface and Test Instrument for Floor Heating System

本研究的主要目的是为地板采暖系统设计一个安全的地板温度，以防止中温烫伤的发生。1996-1997年冬季，对许多居民的地表温度进行了几周的检查。许多受试者坐在或躺在地板上约90分钟。供暖系统使用木地板。在检查期间，该系统的水温被设置在60-80度。将与地板接触的身体的温度与BL（更好的生活）测试件的温度进行比较。BL试件下的温度比身体下的温度高8-9度。通过数值模拟（FEM）估计的两个温度与测量温度吻合良好。

The most important purpose of this study is to estamate a safe floor temperature to prevent moderate temperature burns by the floor heating system. Flor surface temperatures were examined at many residents for a few weeks in winter 1996-1997. A lot of subjects sat or lay on the floor for about 90 minites. The heating system uses wooden floor boards. Water temperatures of this system were set at 60-80 degrees during the examination. The temperature of the body in contact with floor was compared with the temperature of a BL (Better Living) test-piece. Temperatures under the BL test-piece are 8-9 degrees higher than temperatures under the body. Both temperatures to be estimated by numerical simulation (FEM) agree well with measured temperatures.
