Abstract

The human thermal comfort and the indoor healthy air quality in the houses and the offices have become a vital necessity, especially in the state of the development of the contagious virus as the COVID-19. In this study, the evaluation of the air distribution was investigated using a DHTT sensor connected to an ARDUINO card to benefit their simple use and their reasonable price comparing to other tools such as the infrared camera. The measurement of the temperature is made in 14 points divided on two directions: one near the sitting manikin and another in front with the cooling system. The impact of the heat sources was tested. In these conditions, the indoor temperature was examined for an empty room, a room occupied by one person and one computer, a room occupied by two persons and two computers and a lighted room. The experimental results prove that the indoor temperature increases with the multiplication of the heat sources. From a temperature equal to [Formula: see text]C, the PMV curves move away from the comfort zone and the indoor climate becomes hot.

基于ARDUINO系统的制冷条件下室内空气质量实验研究及PMV指数对热源影响的测试

特别是在新冠肺炎等传染性病毒肆虐的情况下，住宅和办公室的人体热舒适和室内健康空气质量已成为至关重要的必需品。在本研究中，使用连接到ARDUINO卡的DHTT传感器对空气分布进行评估，与红外摄像机等其他工具相比，DHTT传感器使用简单，价格合理。温度测量是在两个方向上的14个点进行的:一个靠近坐姿的人体模型，另一个在冷却系统的前面。对热源的影响进行了测试。在这些条件下，对空房间、一人住的房间和一台电脑、两人住的房间和两台电脑和一间有灯的房间的室内温度进行了检查。实验结果表明，室内温度随着热源的增加而升高。当温度等于[公式:见文]C时，PMV曲线远离舒适区，室内气候变热。
