【摘要】 冰蓄冷低温送风技术是为实现电网电力移峰填谷、降低空调系统运行费用而兴起的一门实用综合技术，并逐渐成为空调系统设计的主流。本文对冰蓄冷低温送风系统的设计及其相关问题进行了深入研究，并在此基础上开发了冰蓄冷低温送风系统设计软件。本文的研究课题是涉及制冷与空调、传热学、软件工程等的交叉学科问题。 1、本文针对冰蓄冷低温送风系统的优化设计问题，通过对目前工程中所采用的设计方法、思路的分析研究，发现现有的设计方法对冰蓄冷低温送风系统的特殊性考虑不足，有的甚至沿袭常规系统的设计方法，从而导致设计与实际相差甚远。本文对冰蓄冷低温送风系统设计方案、思路提出了更新，对系统送风量、风机风管的温升、冷却盘管等关键设计计算进行了深入的研究，提出了相应的计算方法。并在基础上，开发了冰蓄冷低温送风系统设计程序。 2、针对目前国内设计采用的建筑物冷负荷计算值比实际冷负荷大、甚至相差成倍之多的问题，对建立在传递函数上的冷负荷系数法进行了研究，编制了计算程序，计算程序有估算与详细计算两种方法。 3、针对传统h-d图作业静态、单一的缺点，本文对描述湿空气湿度的物性参数及其相互关系进行了分析，在传统湿空气h-d图作业的基础上，结合h-d图的动态绘制和热湿过程处理，开发了湿空气h-d图及热湿过程分析程序，为湿空气过程分析、系统的设计提供了基础和分析工具。 4、本文采用厦门火炬软件园大楼为工程实例，对冰蓄冷低温送风系统设计软件进行了测试，同时完成该工程的冰蓄冷低温送风空调系统设计。与常规空调系统相比较，对系统设计进行了经济性能分析。更多还原

【Abstract】 Cold air distribution with ice storage for air-conditioning is a new technology to make balance of the electric supply and to reduce the running cost of system. This technology has been becoming the standard in HAVC in the world. The design process of cold air distribution with ice storage system was investigated in this thesis. A computer software for the design of the system was developed.Concerning with optimization of system design, this thesis disclosed the common problems of ignoring the particularity of the new system by analyzing the traditional design method, which results in the deviation between theoretical and experimental results. The improvement over system design was proposed in this work to eliminate the deviation, and a series of calculation methods for volume of air, temperature rise of pipe and design of cooling coil were established. The software for system design was developed on the basis mentioned above.In most situations, cooling load calculated by traditional methods is larger than the actual one. Concerning with this deviation, coefficient method based on transfer function was investigated in this thesis. The result was used to develop a program for calculation of cooling load.This thesis analyzed the relation of parameters describing humidity of humid air. Based on traditional operating methodology of h-d Graph, a program for drawing dynamic h-d graph and analyzing air conditioning process was developed. It would be used for analysis of air conditioning process and system design.Taking an office building in XiaMen as an example, this thesis not only tested the computer software but also completed system design of cold air distribution with ice storage. At last, this thesis discussed some economical problems of the new system and traditional ones.更多还原
