In 11 climate chamber experiments at air temperatures ranging from 15 to 45 degrees C, a total of 24 subjects, dressed in appropriate clothing for entering a vehicle at these temperatures, were each exposed to four different seat temperatures, ranging from cool to warm. In one simulated summer series, subjects were preconditioned to be too hot, while in other series they were preconditioned to be thermally neutral. They reported their thermal sensations, overall thermal acceptability and comfort on visual analogue scales at regular intervals. Instantaneous heat flow to the seat was measured continuously. At each ambient room temperature, the percentage dissatisfied was found to be a second-order polynomial function of local heat flow. Zero heat flow was preferred at an air temperature of 22 degrees C and the heat flow that minimized the percentage dissatisfied was found to be a single linear function of air temperature in all conditions. The analysis indicates that providing optimal seat temperature would extend the conventional 80% acceptable range of air temperature for drivers and passengers in vehicle cabins by 9.3 degrees C downwards and by 6.4 degrees C upwards.
在11次气候室实验中，空气温度范围为15至45摄氏度，共有24名受试者，穿着适合在这些温度下进入车辆的衣物，每人暴露于四种不同的座椅温度下，温度范围从凉爽到温暖。在一个模拟夏季系列中，受试者被预先设定为过热，而在其他系列中，他们被预先设定为热中性。他们定期在视觉模拟量表上报告自己的热感觉、总体热可接受性和舒适度。连续测量流向座椅的瞬时热流。在每个环境室温下，发现不满意百分比是局部热流的二阶多项式函数。在22摄氏度的气温下，零热流是首选，并且发现在所有条件下，使不满意百分比最小化的热流是气温的单一线性函数。分析表明，提供最佳座椅温度将使车辆驾驶舱内驾驶员和乘客的传统80%可接受气温范围向下扩展9.3摄氏度，向上扩展6.4摄氏度。
