【摘要】：地下車庫采光通風井的設計可以改善車庫內的光環(huán)境和熱環(huán)境,合理的采光通風井設計對人體健康和建筑節(jié)能都有重要意義。本文通過現(xiàn)場實測和模擬分析的方法對廣州某住宅區(qū)地下車庫的采光和通風進行研究,對其采光通風井設計的節(jié)能效果進行評價,并針對其采光通風井設計存在的問題提出優(yōu)化方案。本文在以下幾個方面開展工作:第一,簡要回顧國內外學者在地下車庫采光和通風方面所做的工作,以及對地下車庫采光通風井的類型進行概括總結。第二,對廣州嶺南灣畔住宅區(qū)地下車庫的光環(huán)境進行實測和模擬研究。通過對其光環(huán)境實測發(fā)現(xiàn),該小區(qū)地下車庫存在設計照度值過大、采光通風井設計不合理、燈具控制方式不合理等問題。對某一采光井下的采光系數(shù)實測來對比驗證ECOTECT采光模擬軟件的可行性,并利用軟件對地下車庫的采光進行模擬分析,分析表明采光通風井的設計可以通過利用天然采光節(jié)省照明能耗。第三,對廣州嶺南灣畔住宅區(qū)地下車庫的通風進行實地測試,通過對地下車庫內1.5m高度處的風速、空氣溫度以及壁面溫度和CO濃度的實測發(fā)現(xiàn),車庫內熱環(huán)境受車庫內車輛的排熱影響較大,采光通風井的風壓通風作用對于改善車庫的熱環(huán)境較明顯,依靠自然通風可以全部排出汽車廢氣中的CO。采用實驗驗證了的FLUENT數(shù)值模擬方法,對地下車庫的通風進行模擬分析,結果表明在夏季典型氣象日車流量最多的時刻,地下車庫自然通風量可以滿足標準規(guī)定,不運行風機是可行的,節(jié)省了風機的運行能耗。第四,通過對采光通風井的采光特性和不同尺寸正方形采光通風井的輻射半徑研究,針對嶺南灣畔住宅區(qū)地下車庫采光通風井設計所存在的采光問題,提出5種優(yōu)化設計方案,并采用ECOTECT軟件對不同方案進行模擬分析選出采光最優(yōu)方案,然后利用FLUENT軟件驗證其通風節(jié)能效果,最后對采光通風井的設計提出建議與改造措施。
[Abstract]:The design of lighting ventilation well in underground garage can improve the light environment and thermal environment in the garage. Reasonable design of lighting ventilation well is of great significance to human health and building energy saving. In this paper, the lighting and ventilation of underground garage in a residential area in Guangzhou are studied by the method of field measurement and simulation analysis, and the energy-saving effect of the design of lighting ventilation well is evaluated. The optimization scheme is put forward to solve the problems existing in the design of the lighting ventilation well. The main work of this paper is as follows: first, briefly review the work of domestic and foreign scholars in underground garage lighting and ventilation, and summarize the types of underground garage lighting ventilation well. Secondly, the light environment of underground garage in Lingnan Bay Residential District, Guangzhou is measured and simulated. By measuring the light environment, it is found that there are some problems in the underground garage of this district, such as the design illuminance value is too large, the design of daylighting ventilation well is unreasonable, the control mode of lamps and lanterns is not reasonable, and so on. The feasibility of ECOTECT lighting simulation software is compared and verified by measuring the lighting coefficient of a certain lighting underground, and the lighting of underground garage is simulated and analyzed by using the software. The analysis shows that the design of daylighting ventilation well can save lighting energy by using natural lighting. Thirdly, the ventilation of underground garage in Lingnan Bay residential district in Guangzhou is tested. The wind speed, air temperature, wall temperature and CO concentration are measured at 1.5m height in underground garage. The heat environment in the garage is greatly affected by the exhaust heat of the vehicle in the garage. The ventilation effect of the air pressure in the daylighting ventilation well is more obvious to improve the thermal environment of the garage. Depending on the natural ventilation, the CO-exhaust can be completely discharged from the exhaust gas of the vehicle. The FLUENT numerical simulation method is used to simulate and analyze the ventilation of underground garage. The results show that the natural ventilation rate of underground garage can meet the standard requirement at the time when the traffic flow is the most in the typical weather day in summer. It is feasible to not run fan, saving energy consumption of fan. Fourthly, through the study of the lighting characteristics of the lighting ventilation well and the radiation radius of the square diametric ventilation well with different sizes, aiming at the lighting problems existing in the design of the lighting ventilation well of underground garage in the residential area of Lingnan Bay, five optimal design schemes are put forward. ECOTECT software is used to simulate and analyze the different schemes to select the optimal scheme of lighting, and then FLUENT software is used to verify its ventilation and energy saving effect. Finally, suggestions and renovation measures are put forward for the design of daylighting ventilation shaft.
