摘　　要：介绍一种新概念,利用热电偶的基本原则,将热电偶作为热电空调的一部分,在封闭空间的建筑环境中可有效改进现行空调设计和安装。这种空调系统是在两种不同的环境下,基于热电效应"珀尔帖效应",着重在环境中改变温度这一因素从而达到研究目标。使用"基本单元"设计的热电模块,将不同吸收材料作为散热器的基本单元。使用数值分析法和模拟仿真法,并分析二者之间的误差率。研究借助商业软件ANSYS14.5进行模拟分析,构建了模型,反映出热电模块的真实结构和参考数值,并考虑热元件的电桥梁和接口。模型可作为较灵活的工具提供详细的、包含数值和图形的分析结果。该仿真结果可为建筑方案提供技术支撑。The basic principles of the thermocouple are utilized; the thermocouple being part of thermoelectric air conditioner,will effectively improve the current design and installation of air conditioning in an architectural environment with enclosed spaces. The air conditioning system in two different environments,based on thermoelectric effect- ＂Peltier Effect＂,focused on changing the temperature in environments in order to achieve researching objective,using a＂Base-Unit＂designed as the basic of thermoelectric module imbibed between different materials as heat dissipaters. The numerical analysis and simulation are applied,showing the error percentage between them. Therefore,so as to achieve such objective,the commercial software tool,named ANSYS 14.5 Workbench has been used in order to develop this analysis.The ANSYS 14.5 Workbench model,developed very closely,represents the real configuration and numeric method of a thermoelectric module. It takes into account the thermo elements,their electrical bridges and junctions. All the properties of the materials have been considered constant. Several simulations have been performed using the proposed model. In all cases,the model has become a powerful and flexible tool of analysis presenting detailed numerical and graphical results. However,simulation results have been taken into consideration as base of architectural solutions and applications.
