As the building's outer wall consists of hollow blocks, the hollow hole will transfixion. According to the characteristic, this article proposes a technical method of indoor ventilation, which uses a hollow hole as channel and takes exhaust blower as the power which frequently use in the kitchen and bathroom, then carries on the simulation of ventilated effect for a typical room by the CFD method. With the analysis of the simulation result, the effect of ventilation is fine, and the method can solve the question effectively of city and countryside indoor air qua...
