【摘要】:隨著我國建筑節(jié)能事業(yè)不斷發(fā)展,建筑節(jié)能技術(shù)發(fā)展也突飛猛進(jìn),從理論成熟走向?qū)嶋H項(xiàng)目應(yīng)用。但部分建筑節(jié)能技術(shù)應(yīng)用節(jié)能降耗效果不佳,甚至出現(xiàn)了耗能現(xiàn)象,還有部分地區(qū)節(jié)能技術(shù)應(yīng)用混亂,不合時(shí)宜出現(xiàn)“遍地開花”現(xiàn)象。節(jié)能技術(shù)應(yīng)用暴露的部分問題比較典型,為典型的熱點(diǎn)問題,如南方城市建筑需不需要保溫,能不能搞集中供熱,部分問題比較系統(tǒng),需要科學(xué)合理的理論分析解決,如北方地區(qū)廣泛應(yīng)用土壤源熱泵現(xiàn)象,上述典型熱點(diǎn)問題和系統(tǒng)問題都可以列為建筑節(jié)能技術(shù)適應(yīng)性研究范疇。建筑節(jié)能技術(shù)適應(yīng)性研究要求室外環(huán)境、建筑類型與節(jié)能技術(shù)協(xié)調(diào)統(tǒng)一。本文研究典型地區(qū)典型節(jié)能技術(shù)適應(yīng)性主要分為典型地區(qū)建筑本體節(jié)能技術(shù)適應(yīng)性和供熱制冷系統(tǒng)典型節(jié)能技術(shù)適應(yīng)性。 對(duì)于典型地區(qū)建筑本體節(jié)能技術(shù)適應(yīng)性分析及評(píng)價(jià) 以住宅建筑為例室內(nèi)空調(diào)能耗受多種因素影響,實(shí)測(cè)調(diào)查以及模擬結(jié)果顯示,不同使用模式能耗差別很大。所謂使用模式是指可能影響空調(diào)能耗人的行為,如空調(diào)開啟習(xí)慣等。這就要求建筑節(jié)能設(shè)計(jì)方案不僅充分考慮當(dāng)?shù)貧夂颍€需要適應(yīng)建筑不同使用模式。本文以節(jié)約經(jīng)濟(jì)更接近實(shí)際狀況的使用模式為基礎(chǔ),全面、定量進(jìn)行分析,優(yōu)化設(shè)計(jì)節(jié)能方案,實(shí)現(xiàn)在節(jié)約經(jīng)濟(jì)的住宅使用模式下,使用節(jié)能高效的建筑,從而獲得在使用模式和建筑本體兩方面有機(jī)統(tǒng)一的節(jié)能方案,并以此為基礎(chǔ),研究了廣州(夏熱冬暖地區(qū))、上海(夏熱冬冷地區(qū))采用各種節(jié)能措施的節(jié)能效果和經(jīng)濟(jì)性,指出當(dāng)前該地區(qū)的節(jié)能工作重點(diǎn)。 對(duì)于供熱制冷系統(tǒng)典型節(jié)能技術(shù)適應(yīng)性分析及評(píng)價(jià) 分為三部分,即土壤源熱泵空調(diào)系統(tǒng)考慮熱失衡在典型地區(qū)適應(yīng)性、空氣源熱泵與土壤源熱泵空調(diào)系統(tǒng)在典型地區(qū)的適應(yīng)性對(duì)比、上海(夏熱冬冷地區(qū))住宅建筑供熱方式適應(yīng)性分析。本文采用簡(jiǎn)化模型計(jì)算沈陽(嚴(yán)寒地區(qū))北京(寒冷地區(qū))上海(夏熱冬冷地區(qū))廣州(夏熱冬暖地區(qū))四個(gè)城市應(yīng)用土壤源熱泵和空氣源熱泵空調(diào)系統(tǒng)運(yùn)行能耗和經(jīng)濟(jì)性,分析不同地區(qū)應(yīng)用土壤源熱泵熱失衡問題和與空氣源熱泵的適應(yīng)性對(duì)比。針對(duì)南方城市冬季供暖的焦點(diǎn)問題,本文分析上海地區(qū)供暖方式的影響因素,明確是否適合集中供暖,,并提出更適合該地區(qū)的供暖選擇。
[Abstract]:With the continuous development of building energy conservation in our country, the technology of building energy conservation is developing by leaps and bounds, from the theory mature to the practical project application.However, the energy saving and consumption reduction effect of some building energy saving technologies is not good, even the phenomenon of energy consumption appears, and there is confusion in the application of energy saving technology in some areas, and the phenomenon of "blooming everywhere" appears out of time.Some of the problems exposed in the application of energy-saving technology are quite typical. They are typical hot issues, such as whether buildings in southern cities need heat preservation, whether they can be used for central heating, and whether some of the problems are relatively systematic, requiring scientific and reasonable theoretical analysis and solution.If the ground-source heat pump is widely used in the northern region, the above-mentioned typical hot issues and system problems can be classified as the adaptability of building energy-saving technology.The research on the adaptability of building energy saving technology requires the coordination of outdoor environment, building type and energy saving technology.In this paper, the adaptability of typical energy-saving technology in typical area is mainly divided into two parts: the adaptability of building bulk energy saving technology and the typical energy saving technology adaptability of heating and refrigeration system.Adaptability Analysis and Evaluation of Energy-saving Technology for Building body in typical areaTaking residential buildings as an example, the energy consumption of indoor air conditioning is affected by many factors. The measured results and simulation results show that the energy consumption of different use modes is very different.The so-called mode of use refers to the behavior of people who may affect air conditioning energy consumption, such as air-conditioning opening habits.This requires that the building energy-saving design not only fully considers the local climate, but also needs to adapt to different building use patterns.Based on the use mode of economizing economy closer to the actual situation, this paper analyzes comprehensively and quantitatively, optimizes the design of energy-saving scheme, and realizes the use of energy-saving and efficient buildings under the economical and economical residential use mode.Based on this, the energy saving effect and economy of various energy-saving measures adopted in Guangzhou (hot summer and warm winter area, Shanghai (hot summer and cold winter area)) are studied.The emphasis of energy conservation in this area is pointed out.Adaptability Analysis and Evaluation of typical Energy-saving Technology for heating and Refrigeration systemIt is divided into three parts, that is, the air-conditioning system of ground-source heat pump considers the adaptability of heat imbalance in the typical area, and the adaptability of air-source heat pump and ground-source heat pump is compared in the typical area.Adaptability Analysis of heating Mode of Residential buildings in Shanghai (Hot Summer and Cold Winter area).In this paper, the simplified model is used to calculate the energy consumption and economy of air source heat pump and air source heat pump air-conditioning system in four cities of Shenyang (cold region), Beijing (cold region) and Shanghai (hot summer and cold winter area) Guangzhou (hot summer and warm winter area).The heat imbalance of ground source heat pump in different regions and its adaptability to air source heat pump are analyzed.In view of the focus of heating in southern cities in winter, this paper analyzes the influencing factors of heating mode in Shanghai area, determines whether it is suitable for central heating, and puts forward a more suitable heating choice for this area.
