Numerical and Experimental Study on Indoor Air Distribution and Quality

To optimize and control the indoor air distribution and quality, theindoor temperature and humidity were measured based on indoor fresh air system. The one measurementwas indoor temperature and humidity in both cases of return air and without return air in winter respectively. The other was indoor temperature and humidity in both cases of return air and without return air in summer respectively. In additional, the test room environment was simulated using the finite element analysis software of ANSYS. Through setting a variety of air organization operating modes, the best solution of indoor air flow could be obtained.
