【摘要】：我国建筑业的快速发展导致建筑能耗大幅度上升，而在建筑能耗中空调能耗是最主要的，占有很大比重，因此，空调节能问题显得格外重要。同时，用户对室内环境要求的提高，需要研究室内环境的热舒适状况。基于空调节能和改善热舒适条件的要求，本文以毛细管平面辐射空调为研究对象，全方位探讨了毛细管平面辐射空调的节能性、热舒适性及其在秦皇岛地区的适用性。通过综述毛细管平面辐射空调技术的国内外发展状况可见，该种空调系统一直是以降低空调能耗和改善空调房间热舒适性为主线发展的，属于空调领域的新技术，因此我国应用实例还比较少。针对热舒适性，本文采用数值模拟法，运用Airpak软件建立了空调房间的三维仿真模型，对毛细管平面辐射空调与传统空调系统进行模拟研究。通过分析室内空气速度、温度、空气龄、PMV、PPD，综合评价空调房间的舒适性。针对节能性，本文运用近代热力学的最新成果——火用分析方法，与传统空调对比，研究了毛细管平面辐射空调在能质利用上的高效节能特性，揭示了毛细管平面辐射空调节能不只是节约能量，更重要的是节约能质的本质特性。同时，由于毛细管平面辐射空调能够利用高温冷水和低温热水满足空调房间在不同季节对冷热的需求，该系统扩大了冷能的利用温度范围，从而可以利用更多的冷能取代传统能源，实现在节约能质的基础上进一步在数量上节能的目标。作为适用条件，本文以秦皇岛地区为例，探讨了秦皇岛的自然条件对毛细管平面辐射空调系统的适用性。以一栋别墅为具体对象，设计毛细管平面辐射空调系统，并对其初投资、运行费用等技术经济指标进行了评价。本文研究得出，毛细管平面辐射空调系统在改善室内环境舒适度方面是有效的，，节能特性明显。从对自然冷能利用及改善室内环境舒适度的角度看，这无疑是一种有广泛领域和远大发展前景的空调技术。
[Abstract]:The rapid development of China's construction industry leads to a large increase in building energy consumption, and in the building energy consumption, air-conditioning energy consumption is the most important, occupies a large proportion, therefore, air-conditioning energy saving problem is particularly important. In order to improve the indoor environment requirements, the thermal comfort of indoor environment needs to be studied. Based on the requirements of air conditioning energy saving and improving thermal comfort conditions, this paper takes the capillary plane radiation air conditioning as the research object. The energy saving, thermal comfort and applicability in Qinhuangdao are discussed. Through the review of the development of capillary plane radiation air conditioning technology at home and abroad, this kind of air conditioning system has been to reduce the energy consumption of air conditioning and improve the thermal comfort of air conditioning rooms as the main line of development. Belong to the new technology in the field of air-conditioning, so our application examples are relatively small. Aiming at thermal comfort, the three-dimensional simulation model of air conditioning room is established by numerical simulation method and Airpak software. This paper studies the simulation of capillary plane radiation air conditioning system and traditional air conditioning system. By analyzing indoor air velocity, temperature, air age and PMV PPDs, the comfort of air conditioning room is comprehensively evaluated. In view of energy saving, this paper studies the high efficiency and energy saving characteristics of capillary plane radiation air conditioning in the utilization of energy quality by using exergy analysis method, which is the latest achievement of modern thermodynamics, and compared with traditional air conditioning. It is revealed that the energy saving is not only energy saving, but also the essential characteristic of energy saving in capillary plane radiation air conditioning. Because the capillary plane radiation air conditioning can use high temperature cold water and low temperature hot water to meet the demand of air conditioning room in different seasons, the system expands the temperature range of using cold energy. Thus, more cold energy can be used to replace traditional energy, and the goal of energy saving in quantity can be achieved on the basis of saving energy and quality. As a suitable condition, this paper takes Qinhuangdao area as an example, discusses the applicability of Qinhuangdao's natural condition to the capillary plane radiation air conditioning system, and takes a villa as the concrete object. The capillary plane radiation air conditioning system is designed and its technical and economic indexes such as initial investment and operation cost are evaluated. In this paper, it is concluded that the capillary plane radiation air conditioning system is effective in improving indoor environment comfort, and the energy saving characteristics are obvious. From the point of view of using natural cold energy and improving indoor environment comfort. This is undoubtedly a wide range of areas and broad prospects for the development of air conditioning technology.
