Indoor Airflow and Human Thermal Comfort Research on One of the Chongqing Air-conditioned School Dormitory in Winter with CFD Simulation

Currently, numerical simulation research on indoor air and human thermal comfort usuallyfocuses on the air-conditioning room in summer. This paper uses an Air-conditioneddormitory in winter as a model to study indoor airflow and human thermal comfort. Thispaper uses k -e three-dimensional turbulence model and N-S equation, considers airflowwith room shape and obstacles as one, calculates the indoor airflow and heat transferproblems with overall solution, studies indoor air form especially velocity field withnumerical simulation. From the numerical simulation results, we can know that the layout ofthe school dormitory and air supply mode is appropriate, the air velocity and other parametersmeet the relevant standards, and conducive to obtain comfortable indoor thermal environment.The results prove that k -e three-dimensional turbulence model is suitable for calculatingindoor airflow field, and can be used in other air-conditioned rooms with different structure inwinter.
