Numerical Simulation Evaluation on Airflow Organization and Thermal Comfort of Air-Conditioning System Based on Internet of Things Technology

With the emergence of computers, the Internet and mobile communication networks, the rise and development of Internet of Things technology has become the main content of the third technological revolution. Based on multimedia technology, this paper discussed the use of multimedia technology to simulate the air distribution and thermal comfort of office air conditioners, and analyzed the thermal comfort values of air conditioners in the office working environment. Therefore, this paper proposed an intelligent air-conditioning system architecture based on the Internet of Things, which combined the Internet of Things technology with cloud computing platform and big data technology, and used CFD software to study the air-conditioning system. The test results showed that in the vertical cabinet air-conditioned office, when the air is supplied in the horizontal direction, the satisfaction of the indoor workbench is 50%; in the process of air supply at 60°, the satisfaction rate reaches 75%; when the air supply angle is 45°, the satisfaction rate reaches 100%. Therefore, the direction of air supply was selected to be 45°. At this angle, the thermal comfort of all parts is very good, and there is no waste.
