Comparison of Displacement Ventilation, Mixing Ventilation and Underfloor Air Distribution System

摘要

At present, the scientific community attaches importance to the problem of indoor air quality and building energy conservation seriously, the people's requirement of indoor living environment is also improving constantly, improving the problem of air conditioning energy consumption of building energy consumption and the way of ventilation has been on the agenda. In view of this situation, we researched and compared the principle, merit and demerit as well as applicable occasions of the displacement ventilation, mixing ventilation and underfloor air distribution. In the process of investigation and study, we found that the practical application of the air conditioning should be on the basis of different occasions and choose different way of ventilation accordingly, only then can we reduce the energy consumption of air conditioning, alleviate the problem of energy shortage and improve the indoor air quality.
