【摘要】：随着我国建筑节能事业不断发展，建筑节能技术发展也突飞猛进，从理论成熟走向实际项目应用。但部分建筑节能技术应用节能降耗效果不佳，甚至出现了耗能现象，还有部分地区节能技术应用混乱，不合时宜出现“遍地开花”现象。节能技术应用暴露的部分问题比较典型，为典型的热点问题，如南方城市建筑需不需要保温，能不能搞集中供热，部分问题比较系统，需要科学合理的理论分析解决，如北方地区广泛应用土壤源热泵现象，上述典型热点问题和系统问题都可以列为建筑节能技术适应性研究范畴。建筑节能技术适应性研究要求室外环境、建筑类型与节能技术协调统一。本文研究典型地区典型节能技术适应性主要分为典型地区建筑本体节能技术适应性和供热制冷系统典型节能技术适应性。对于典型地区建筑本体节能技术适应性分析及评价以住宅建筑为例室内空调能耗受多种因素影响，实测调查以及模拟结果显示，不同使用模式能耗差别很大。所谓使用模式是指可能影响空调能耗人的行为，如空调开启习惯等。这就要求建筑节能设计方案不仅充分考虑当地气候，还需要适应建筑不同使用模式。本文以节约经济更接近实际状况的使用模式为基础，全面、定量进行分析，优化设计节能方案，实现在节约经济的住宅使用模式下，使用节能高效的建筑，从而获得在使用模式和建筑本体两方面有机统一的节能方案，并以此为基础，研究了广州（夏热冬暖地区）、上海（夏热冬冷地区）采用各种节能措施的节能效果和经济性，指出当前该地区的节能工作重点。对于供热制冷系统典型节能技术适应性分析及评价分为三部分，即土壤源热泵空调系统考虑热失衡在典型地区适应性、空气源热泵与土壤源热泵空调系统在典型地区的适应性对比、上海（夏热冬冷地区）住宅建筑供热方式适应性分析。本文采用简化模型计算沈阳（严寒地区）北京（寒冷地区）上海（夏热冬冷地区）广州（夏热冬暖地区）四个城市应用土壤源热泵和空气源热泵空调系统运行能耗和经济性，分析不同地区应用土壤源热泵热失衡问题和与空气源热泵的适应性对比。针对南方城市冬季供暖的焦点问题，本文分析上海地区供暖方式的影响因素，明确是否适合集中供暖，，并提出更适合该地区的供暖选择。
[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.
