【摘要】：近年來隨著城市化的大規(guī)模推進(jìn)，城市中心區(qū)因其建筑密度大，風(fēng)速低，熱島效應(yīng)愈加明顯。尤其在夏季，中心區(qū)內(nèi)空調(diào)排熱巨大，但散熱不佳，導(dǎo)致氣溫升高，微氣候條件更加惡劣，進(jìn)而影響到中心區(qū)內(nèi)建筑的空調(diào)能耗，造成惡性循環(huán)。然近年來針對建筑空調(diào)的研究主要集中在單純的室內(nèi)空調(diào)能耗分析或空調(diào)排熱對室外熱環(huán)境的影響，尚未將空調(diào)排熱導(dǎo)致周邊熱環(huán)境的變化及對建筑空調(diào)能耗的影響聯(lián)系起來進(jìn)行研究。 本文采用對流輻射耦合模擬方法和空調(diào)能耗計(jì)算方法針對當(dāng)前公共建筑中較為流行的中央空調(diào)的排熱方式和排熱口設(shè)置位置的差異對建筑空調(diào)能耗的影響開展研究，，同時探討了分體式空調(diào)設(shè)置于立面不同位置時對建筑空調(diào)能耗的影響。本研究從街區(qū)熱環(huán)境、建筑周邊熱環(huán)境、建筑相鄰空氣層熱環(huán)境三個層面進(jìn)行分析，并提出根據(jù)建筑相鄰空氣層平均氣溫的變化得到空調(diào)能耗的變化量，總結(jié)趨勢，得到一般規(guī)律。并根據(jù)研究結(jié)論提出了建筑設(shè)計(jì)中空調(diào)排熱形式和排熱口設(shè)置位置的設(shè)計(jì)原則。 研究結(jié)果表明：空調(diào)使用不同的排熱方式以及排熱口設(shè)置在建筑不同的位置對建筑自身的空調(diào)能耗有很大影響。
[Abstract]:In recent years, with the large-scale development of urbanization, the heat island effect is becoming more and more obvious in the central district because of its high building density, low wind speed, especially in summer, the air conditioning in the central area is huge, but the heat dissipation is not good. As a result, the temperature rises and the microclimate conditions become worse, which in turn affects the energy consumption of air conditioning in the central area. However, in recent years, the research on building air conditioning is mainly focused on the analysis of energy consumption of indoor air conditioning or the effect of air conditioning exhaust on the outdoor thermal environment. The influence of exhaust heat on the energy consumption of building air conditioning has not been studied. In this paper, the convection radiation coupling simulation method and the air conditioning energy consumption calculation method are used to analyze the influence of the difference of the central air conditioning exhaust mode and the location of the exhaust outlet on the building air conditioning energy consumption. Research. At the same time, the paper discusses the influence of separate air conditioning on building air conditioning energy consumption when it is located in different positions of elevation. This study is analyzed from three aspects: block thermal environment, building surrounding thermal environment, building adjacent air layer thermal environment. According to the change of the average air temperature in the adjacent air layer of the building, the change of the energy consumption of the air conditioning system is put forward, and the trend is summarized. According to the conclusion of the research, the design principles of the air conditioning exhaust heat form and the location of the outlet in the architectural design are put forward. The results show that the air conditioning energy consumption is greatly affected by the different ways of exhaust air conditioning and the location of the exhaust outlet in the building.
