导言客車空气調节装置通常在稳定状态下分析討論,設計师所考虑的空調系統在固定不变的滿負荷情况下进行計算。在本文中,作者試图在蒸发冷却器直接作用下,用分析及試驗的方法去研究客車空調过程的热流情况,以求得影响降溫、加热及通风系統等瞬时状态各因素的特性数据。而且,将这些因素的相互关系用无因次綫性微分方程表示出来,这些方程可能用电子模拟計算机来求解。根据这些方程式,作者設計了一个空調分析器,用此分析器可以按照意愿,将不同情况的过程重新显示出来,并将瞬时的状态进行討論。
Introduction Passenger car air conditioners are typically analyzed and discussed at a steady state and the air conditioning system under consideration by the designer is calculated at a constant, full load. In this paper, the author tries to use the method of analysis and experiment to study the heat flow of passenger car air-conditioning process under the direct action of evaporative cooler, in order to obtain the characteristic data of various factors that affect the instantaneous state of cooling, heating and ventilation system. Moreover, the correlation of these factors is illustrated by a dimensionless linear differential equation, which may be solved electronically with a computer. Based on these equations, the author devised an air conditioner analyzer, with which the analyzer can redistribute the process of different situations as desired and discuss the instantaneous status.
