一、前言本文的目的是利用温差电制冷的基本公式和传热学的基本原理,导出温差电元件的热电性能与空气状态参效之间的函数关系,从而为温差电堆的最佳设计计算提供一种简单而正确的方法。要精确地预估待设计的热电空调系统的性能,必须利用能准确地表达空调系统及其特性的各种关系式。即要详细地列出一系列足以充分说明系统性能的特性参数,表达出该系统与其周围环境的相互作用,把它们按其变化规律列出数学表达式(方程组),然后联立求解,方能得出在一定工况下该系统的性能数据。但是,用以充分说明热电系统及其与周围环境的相互作用所需参数数
I. INTRODUCTION The purpose of this paper is to derive the functional relationship between the thermoelectric properties of the thermoelectric element and the air state parameters using the basic equations of thermoelectric cooling and the basic principles of heat transfer to calculate the optimum design for the thermopile Provide a simple and correct method. To accurately predict the performance of a thermoelectric air-conditioner system to be designed, various relationships must be used that accurately represent the air-conditioning system and its characteristics. That is, a series of characteristic parameters should be listed in detail to fully describe the system performance, to express the interaction between the system and its surroundings, to list the mathematical expressions (equations) according to their variation rules, and then to solve them in series Can be drawn under certain conditions the system performance data. However, the number of parameters required to adequately account for the thermoelectric system and its interaction with the surrounding environment
