Gagge两节点模型在预测环境对人体产生的整体热影响时具有相当的准确性,能满足大多数工程研究及热舒适评价的需求,该模型在实际应用中认可度较高。但是在低气压环境下,人体周围的环境参数及人体的一些生理参数发生了变化,直接应用二节点模型会存在一定问题。因此,本文通过高原低压舱模拟低气压环境,对Gagge两节点模型在3 000 m内的无症状高原反应域低气压环境下的适用性进行了实验研究,同时对两节点模型进行低压下的改进,并对改进后的模型进行验证,结果表明,皮肤温度的测量值和模拟值吻合较好,改进后的两节点模型在低气压环境下应用的准确性较高。
The Gagge two-node model has considerable accuracy in predicting the overall thermal impact on the human body and can meet the needs of most engineering researches and thermal comfort evaluations. The model has a high degree of acceptance in practical applications. However, under low pressure environment, the environmental parameters around the human body and some physiological parameters of the human body have changed. There will be some problems in the direct application of the two-node model. Therefore, this paper studies the applicability of the two-node Gagge model under the low-pressure environment of asymptomatic plateau reaction field within 3 000 m by simulating the low-pressure environment in the altiplano low-pressure cabin. At the same time, the two-node model is improved under low pressure The results show that the measured skin temperature is in good agreement with the simulated value, and the improved two-node model has a higher accuracy in low-pressure environment.
