Indoor Wind Environment Analysis of Two Kind of Household Types Base on Bidirectional and Unidirectional Windowing

抄録

As the country's economic development rapidly develops, people's living standards have been greatly improved. Not only does space utilization of the housing is very high when purchasing the house, but the air quality problem in the room is begun to be focused. The uniform wind farm is an important factor for the comfort of the residence, and two different residential types are selected in this paper, a window running through the living room in the south and the north of the draft, a window in both north and south, and the other only with a window in the south, based on the fluid mechanics analysis software CFD ANSYS for fluent to establish a residential model, and a simulation of the indoor air environment of the two types of housings, so as to explore the uniformity and smoothness of the air flow of the two types of housings. The results show that the air circulation is smooth and uniform, the flow speed is fast, the vortex area produced in the room is less, the ventilation efficiency is high, and only the door model of south to open window, the air flow is slow or stagnant, producing a large number of vortex areas, which is not conducive to indoor air quality improvement. Hopefully, we'll be able to help the building designers and the consumers who buy the house.
