Research on Thermal Comfort of Laboratory Human Body Based on Numerical Simulation

Abstract

As a public place where teaching researchers need to stay for a long time, the laboratory should be able to meet the requirements of health, comfort, environmental protection and effective use of energy. Based on the characteristics of the laboratory and the natural ventilation in the laboratory, combined with the measured values of relevant parameters in the laboratory, this paper uses the numerical simulation software Airpak 3.0 to simulate the air distribution and thermal environment in the laboratory. The indoor thermal environment is analyzed from the velocity field, temperature field and air age, and the simulation results of thermal environment parameters at different locations in the laboratory are given, which provides a certain method and theoretical basis for improving the thermal environment in the laboratory and human comfort. Finally, under the conditions of natural ventilation and changing the air inlet temperature, the thermal comfort of the laboratory is evaluated and the conclusion is drawn that when the air inlet temperature is 24 ℃, the human body will feel the most comfortable to the thermal environment of the laboratory.
