【摘要】 随着我国国民经济迅速发展,能源、资源的短缺与环境污染已成为十分严重的问题,其中建筑节能和环境问题是重要方面之一。过去一段时间,城市的建筑节能和环境问题逐步得到重视,但在村镇地区,尚未引起足够的关注。村镇地区巨大的人口数量和不断提高的生活水平将带来建筑能耗逐步增加,而村镇电力和其他能源输送损耗比城市更大。同时,在村镇地区具有更多的地下水等低品位能源资源。因此,研究地下水空调等低品位能源利用技术是改善村镇居住环境,缓解能源紧张、保护我国生态环境的一种直接、有效的措施。本文首先指出了本研究论文的学术背景及理论、实际意义,回顾了地下水空调的理论研究,介绍了地下水空调的定义和特点。通过设计和搭建地下水空调实验系统,测试了系统的整体运行效果和空调房间的热舒适情况。实验证明,地下水空调能有效地降低房间空气温度,湿度也可以保持在一个可以接受的范围,房间的热舒适得到了很大的改善,人体热感觉适中。运行期间,地下水空调系统平均COP为5.9,比其他各类空调系统的COP都高,该系统是节能有效的空调系统。介绍了干湿工况等价法的原理与计算步骤,利用此方法计算了各个工况下风机盘管的制冷量,并对风机盘管变工况热工性能进行研究,整理出了风机盘管变工况下的热工性能曲线,为地下水空调风机盘管的设计和选型提供了可靠的理论依据。提出了地下水空调潜力分析评估系统的框架与模型的建立方法,并在中国各省会城市和直辖市(代替附近村镇)加以应用分析。这种新的尝试旨在评估各地区村镇住宅的地下水空调利用潜力,并对风机盘管的选择提供设计参考依据以及作为建立新的相关标准、规范的重要参考。在总结国内外地下水空调系统设计、施工经验的基础上,结合本研究论文成果,提出了地下水空调系统设计的详细设计步骤与方法,以及需要选用的设计参考规范及标准。对地下水空调系统的设计与施工有一定的参考价值,可用于指导村镇住宅建筑的地下水空调工程实践。更多还原

【Abstract】 With the increasing growth of Chinese national economy,the shortage of energy and resource has already became a serious problem, among which the building energy conservation and environmental problem are the most important issues. Over the past period of time, attention has been gradually paid to urban building energy efficiency; however, it has not been concerned enough in rural area. The huge population and increasingly improved living standard will lead to the increasing building energy consumption. And the transportation loss of electric power and other energy sources in rural area is more than those in the urban area. At the same time, there are more low-grade energy sources such as groundwater in rural area. As a result, the application of groundwater air-conditioning is a direct and effective measure to improve the rural building environment, relieve the energy shortage and protect the environment.The background and practical meaning of groundwater air-conditioning was presented firstly in this paper, and then the stage of study on groundwater air-conditioning, its definition and the characteristic was reviewed.Base on the design and built of experiment system, the operation effect of groundwater air-conditioning system and thermal comfort was tested. It was proved that the air temperature of air-conditioning room could be effectively reduced and the humidity could also maintain in an acceptable range when the system was running. Additionally,thermal comfort of the room was also improved. During operation period, the system COP was 5.9, which was higher than other air-conditioning systems. This system is a green air-conditioning system that can be energy-conserving.The theory and calculation steps of wet-dry conditions equivalent method were introduced in this paper, and the cooling capacity in different conditions of FCU was calculated by using this method. The thermal performance curves of the FCU working under mutative conditions were obtained. Moreover, a reliable academic evidence for the design and choice of groundwater air-conditioning system’s FCU was also given in this paper.The method of analyzing potential of groundwater air-conditioning system was put forward in this paper, which was applied to analyze the potential in provincial cities and municipalities in China. This new attempt was used to evaluate the groundwater air-conditioning potential of each rural area, provide evidence for the choosing of FCU and give a reference to establish new relevant standards and criterions.Finally, on the base of summarizing the design and construction experience of domestic and overseas groundwater air-conditioning systems, with the paper’s research results, the detailed design process of the groundwater air-conditioning system is put forword in the paper. Besides, the norms and standards refers to the design is also included. It is valuable for the design and construction and can be applied to instruct the practice of the groundwater air-conditioning system in the residence in the countryside.更多还原
