项目摘要

Both of thermal comfort and energy consumption depend on the two important factors, system control performance and building thermal characteristics. It is required that accurate simulation method and total evaluation method on space thermal comfort and energy consumption. The purpose of this research is to establish such method, based on the survey of space environments and energy consumption in the actural buildings and the experiments on the thermal response of building. The points are following.1. Analysis of termal comfort and energy consumption in the office building. Method of computer simulation of thermal comfort and energy consumption is developed. And the effects of various factors related to building/system design or system operation,are analized by this method,in the model of popular office building.2. Survey and experiments on the thermal response of internal furniture. Thermal characteristics of internal furniture have important effects on space heating peak load. Thermal capacity of the internal furniture is made clear from the actual survey in the popular office spaces. On the other hand,from the experiments,thermal responses of various furniture are analized. Standard thermal absorption response of furniture are obtained from this investigation.3.Analysis of thermal effects of insulation method. By the computer simulation,inside-out and outside-in insulated spaces are compared each other from the standpoints of energy conservation.4.Research on the thermal storage load in the intermittent heating operation. The characteristics of the thermal storage load are Analyzed and a simplified method of this storage load calculation is proposed, which is useful to heating system design.5.Thermal analysis of air-conditioning heat exchangers. Analytical method of finned serpentine counterflow heat exchangers is investigated and the characteristics of various types of heat exchangers are analyzed. applicatable charts for system design are proposed.

热舒适性和能耗都取决于系统控制性能和建筑热工特性这两个重要因素。这就要求对空间热舒适性和能耗进行精确的模拟和全面的评价。本研究的目的是在对实际建筑的空间环境和能耗进行调查的基础上，通过对建筑热响应的实验研究，建立一种新的建筑热响应分析方法。要点如下。1.办公建筑热舒适性与能耗分析。提出了热舒适性和能耗的计算机模拟方法。并以某办公建筑为例，分析了建筑/系统设计或系统运行等相关因素对办公建筑的影响.室内家具热响应的测量与实验。室内家具的热工特性对供暖高峰负荷有重要影响。通过对流行办公空间的实际调查，明确了家具内部的热容量。另一方面，通过实验分析了不同家具的热响应。通过实验得到了家具的标准吸热响应。3.保温方法的热效应分析。通过计算机模拟，从节能的角度对内外两种保温方式进行了比较。4.间歇供暖运行中蓄热负荷的研究。分析了蓄冷负荷的特点，提出了蓄冷负荷的简化计算方法，为供热系统设计提供了参考。5.空调换热器的热力分析。研究了翅片式蛇形管逆流换热器的分析方法，分析了各种换热器的特点。提出了系统设计的实用图表。
