前言制定铁路试制和运用车辆的快速试验方法,对于缩短推行新技术的期限和提高车辆的运用效率,都有很大的实际意义。直接采用模拟计算条件的方法,而不需要使用任何复杂的技术措施,就能加速某些项目的试验。其中就包括有全苏铁道运输科学研究院为客车制冷和采暖系统所制定的一些快速热工试验方法。本文叙述了借助建立与运用情况相符合的定置条件的热负荷作用下空调设备的快速试验方法。这种方法勿需通过各种气候地区 Preface It is of great practical significance to formulate a rapid test method for the trial production and application of railways to shorten the time limit for the introduction of new technologies and to improve the efficiency of vehicles. Direct use of simulation methods to calculate the conditions, without the need to use any complicated technical measures, we can speed up the test of some projects. Among them, there are some rapid thermal test methods developed by the Institute of Transportation Research of the All-Russia Railway for the cooling and heating systems of passenger cars. This paper describes the rapid test method of air-conditioning equipment under the heat load with the help of setting conditions that are consistent with the application conditions. This method does not need to go through a variety of climatic regions
