1、CFD在住宅室内设计中的应用（The application of CFD in residential interior design）Draft date: 2010-01-05Author profile: su east (1985 -), male, master of materials science and engineering, chongqing university, chongqing 400045Gong qiyi (1966 -), male, master tutor, associate professor, department of materials s
2、cience and engineering, chongqing university, chongqing 400045East China gong qiyiAbstract: Airpak is a CFD special software for simulating indoor airflow, for engineering and scientific research. The software simulates an interior designerThe air flow organization and thermal comfort of the case, t
3、hrough the adjustment of comparative analysis, verified CFD to improve the indoor thermal environment and the feasibility of improving energy efficiency.Key words: Airpak, interior design, energy saving, air flow organizationMiddle image classification no. : TU834.852 literature identification code:
4、 AIn residential interior design, reasonable indoor air flow organization can not only create comfortable and healthyKangs bedroom thermal environment, also can reduce the residential future use energy consumption. CFD software is the meterThe abbreviation for Computational Fluid Dynamics software i
5、s specially usedTo conduct flow field analysis, flow field calculation, and flow field prediction software. With the help of CFD softwareIndoor air flow simulation, we can understand the indoor air distribution details, and passThe analysis takes place in the flow field, the interior design is adjus
6、ted, the reasonable organization roomInternal air flow, improve the energy efficiency and comfort of the house, and achieve the best design result.1. Air flow organization and energy saving in air-conditioning roomGenerally speaking, the air flow organization of air conditioning room is to point to
7、air conditioning room send, return windThe choice and arrangement of the mouth makes the air sent into the room reasonably flow and distribute in the room.The temperature, humidity, speed and cleanliness of air conditioning room can be fully filledFoot production process and human thermal comfort re
8、quirements. However, for the average house, the roomThe dimension is small, limit the placement of indoor air conditioner to some extent, and indoorThe position of the machine is also limited by the location of the outdoor machine and the length of the piping. The principle of interior designAccordi
9、ng to the state characteristics of personnel activities in different functional Spaces and the air conditioningThe position is arranged for the layout of the plane, so that the air flow organization under the conditions of the specific operating conditions is to meet the needs of the peopleThe therm
10、al comfort level of the activity intensive area is subject to the area with less personnel activityIt can relax the requirement of comfort, thereby reducing the energy consumption of air conditioning and improving energy efficiencyTo save energy.2. CFD simulation of interior design schemeThis paper
11、takes the two design schemes of the seventh floor of a residential district in chongqing as an exampleThe establishment work of the model, take the space bigger, the furniture furnishings the more complicated living room is the researchThe object (see figure 1, figure 2). The length, width and heigh
12、t of the living room are 6.5 m by 6 m x2.8 m, the walls are painted inside, the ceiling of the acoustic gypsum board, the adjacent room and the corridor are air-conditioned roomsIn between, do not consider metope heat transfer. The living room is refrigerated by haier cabinet in summer, most of them
13、The time staff sat in the sand.2.1 physical modelConsidering the computer memory and computational speed, the premise of calculating the result is not affectedNext, the model is properly simplified: the room porch and the left glass surface are complemented by indoorThe Windows were closed and the t
14、wo doors in the living room filled with solid walls. Upper part of the air-conditioning chamberMaterial, etc.Especially in the current beginning stage, our country has not established a set of goodEconomic, social and moral incentives to compensate developers for green eco-homesThe extra inputs in t

Ecological housing will become a 21st-century human applicationThe technology seeks to coexist with the natural harmonious coexistence and sustainable development of the ideal residential building mod
