【摘要】：傳統(tǒng)的風機盤管加新風空調(diào)系統(tǒng)存在熱濕耦合處理、難以適應(yīng)熱濕比的變化以及風機盤管濕工況運行等方面的問題,不僅能耗大而且會導致霉菌繁殖和傳播,影響室內(nèi)的空氣品質(zhì)。輻射吊頂結(jié)合獨立新風系統(tǒng)作為一種新的空調(diào)系統(tǒng)形式,其特點是將溫度濕度分開處理,有效避免了傳統(tǒng)空調(diào)系統(tǒng)存在的問題。本文對輻射吊頂結(jié)合獨立新風系統(tǒng)應(yīng)用于住宅建筑的熱舒適性、節(jié)能性和經(jīng)濟性進行了研究。本文第二章研究了輻射吊頂結(jié)合獨立新風系統(tǒng)應(yīng)用于住宅建筑的熱舒適性。采用Airpak軟件建立了住宅模型,分別采用不同送回風形式,以及不同輻射面的室內(nèi)氣流組織進行數(shù)值模擬,并從溫度場和速度場角度對不同工況下的模擬結(jié)果進行對比分析；接著對采用輻射吊頂結(jié)合獨立新風系統(tǒng)的房間進行了舒適性分析。本文第三章為實驗部分,具體分析了輻射吊頂結(jié)合獨立新風系統(tǒng)在實際工程中的運用,并實際測量了穩(wěn)定運行工況下,房間內(nèi)的溫度變化,實驗結(jié)果與模擬結(jié)果吻合度較高,模擬結(jié)果具有較高的可信度。同時對采用輻射吊頂結(jié)合獨立新風系統(tǒng)常出現(xiàn)的結(jié)露問題,在分析結(jié)露現(xiàn)象和原理的基礎(chǔ)上,結(jié)合工程應(yīng)用,提出了防止結(jié)露的措施。本文第四章和第五章在熱舒適性研究的基礎(chǔ)上,進一步研究了輻射吊頂結(jié)合獨立新風系統(tǒng)的節(jié)能性和經(jīng)濟性。首先用DeST軟件計算建筑各項全年逐時負荷。接著建立能耗計算模型,對兩種空調(diào)系統(tǒng)的全年運行能耗進行了計算分析。其次,在能耗分析的基礎(chǔ)上,建立初投資計算模型,對兩者的初投資和全年運行費用進行了計算,并采用靜態(tài)經(jīng)濟評價方法和動態(tài)經(jīng)濟評價方法對輻射吊頂結(jié)合獨立新風系統(tǒng)進行了評價分析,體現(xiàn)出良好的經(jīng)濟性,目前輻射吊頂在實際工程中應(yīng)用的不多,市場認可度不高,但隨著輻射吊頂結(jié)合獨立新風系統(tǒng)應(yīng)用的普及,在初投資方面其與傳統(tǒng)風機盤管的價格差距會越來越小,到那時輻射吊頂結(jié)合獨立新風系統(tǒng)在經(jīng)濟性方面的優(yōu)勢會完全表現(xiàn)出來。通過對輻射吊頂結(jié)合獨立新風系統(tǒng)應(yīng)用于住宅建筑熱舒適性、節(jié)能性和經(jīng)濟性的研究,為其在夏熱冬冷地區(qū)的推廣應(yīng)用提供參考。
[Abstract]:The traditional Fan-Coil Unit and fresh Air conditioning system has the heat and humidity coupling treatment, which is difficult to adapt to the change of the ratio of heat to humidity and to the operation of the Fan-Coil Unit under wet conditions. It not only consumes energy but also leads to the propagation and propagation of mold. Affect indoor air quality. As a new type of air conditioning system, radiation ceiling combined with independent fresh air system is characterized by the separation of temperature and humidity, which effectively avoids the problems existing in the traditional air conditioning system. In this paper, the thermal comfort, energy saving and economy of radiation ceiling combined with independent fresh air system in residential buildings are studied. In the second chapter, the thermal comfort of radiation ceiling combined with independent fresh air system in residential buildings is studied. The residential model is established by Airpak software. The numerical simulation of indoor airflow is carried out by using different return air forms and different radiation surfaces, and the simulation results under different working conditions are compared and analyzed from the point of view of temperature field and velocity field. Then, the comfort of the room with radiation ceiling and independent fresh air system is analyzed. The third chapter of this paper is the experimental part. The application of the radiation ceiling combined with the independent fresh air system in the actual project is analyzed, and the temperature change in the room under the steady operation condition is measured. The experimental results are in good agreement with the simulation results. The simulation results have high reliability. At the same time, on the basis of analyzing the phenomenon and principle of condensation, combined with the engineering application, the measures to prevent the condensation of dew are put forward for the problems often occurring in the radiation ceiling combined with the independent fresh air system. In the fourth and fifth chapters, based on the study of thermal comfort, the energy saving and economy of radiation ceiling combined with independent fresh air system are further studied. First, the time-by-time load of the building was calculated with the software of rest. Then the energy consumption calculation model is established, and the annual energy consumption of the two air conditioning systems is calculated and analyzed. Secondly, on the basis of energy consumption analysis, the calculation model of initial investment is established, and the initial investment and annual operating cost are calculated. The static economic evaluation method and the dynamic economic evaluation method are used to evaluate and analyze the radiation ceiling combined with the independent fresh air system, which reflects the good economy. At present, the radiation ceiling is not used much in the actual project, and the market recognition is not high. However, with the popularization of radiation ceiling combined with the application of independent fresh air system, the price gap between the radiation ceiling and traditional fan coil units will become smaller and smaller in initial investment. By then, the economic advantages of the radiation ceiling combined with the independent fresh air system will be fully demonstrated. The application of radiation ceiling and independent fresh air system to the thermal comfort, energy saving and economy of residential buildings is studied, which provides a reference for its popularization and application in hot summer and cold winter area.
