Numerical simulation of ammonia concentration distribution and optimization of makeup air for public lavatory of highrise buildings

Taking the public lavatory in office floors of Wuhan Center as an example, simulates the ammonia concentration in the different conditions by changing the makeup air form, position of air inlet, air change rate and the position of air outlet using Fluent software. The results show that the effect of top supply air is better than that of the air leak from the door and lateral air supply, the optimal air change rate is 10 times per hour when adopting top supply air, and the height of the air outlet is 0.2 m above the release surface of pollute source.
