Differences Research on Human Overall Comfort Under Low Pressure
Source abstract
Abstract
A low-pressure environment can significantly affect human physiological mechanisms. It causes differences in human overall comfort evaluation at different pressures. Current research mainly focuses on the impact of single environmental factors on human comfort under low pressure. However, studies considering multiple environmental factors are lacking. This paper was based on the effective-function method. Thermal, luminous, and acoustic comfort experimental studies were carried out under standard atmospheric pressure and low pressure. In this study, we conducted an in-depth exploration of the human overall comfort differences under low pressure. The key findings were as follows: (1) There were differences in single environmental comfort evaluation under low pressure. (2) The influence order of unit changes in environmental factors on overall comfort was determined. Within the comfort zone, the variations of 1 °C, 100 lx, and 5 dB caused similar changes in overall comfort evaluation. When a factor deviated from the comfort zone, it became the dominant factor affecting the POCV (Predicted Overall Comfort Vote). (3) In the peak zone of overall comfort evaluation under low pressure, considering energy-saving needs, a slightly cooler environment in winter and a slightly warmer environment in summer were chosen. And the illuminance was shifted to the left of the x-coordinate. The tolerable zone became smaller, and it was easier to reach the lower limit. (4) The comfort zone nomograms for common working condition parameters were drawn. Through parameter interaction, “superior” parameters were used to compensate for “inferior” ones, thereby improving the human overall comfort evaluation. Based on these findings, this research provides a theoretical basis and data support for the design of aerospace and high-altitude environments. It offers beneficial references and ideas for the integrated development of interdisciplinary fields.
