本文是一篇科研工作的总结报告。论述了一种测定空调器制冷量的简易且又精确的方法——风管热平衡法。本文除了叙述该方法的原理、特点、结构及设备外,还特别方介绍了最近我们为提高测量精度所做的工作及试验装置的误差分析。本试验装置测量结果的标准误差可控制在3%以内,完全符合空调器规范的要求。我们用此法对国内外较成熟的空调器进行了实测,测定值和铭牌制冷量的偏差一般也在5%以内。由于本方法造价低廉、测量方便且又有相当高的特度,故已被许多单位仿制采用。
This article is a summary of research work. A simple and accurate method for determining the air conditioner cooling capacity is discussed - air duct heat balance method. In addition to describing the principle, characteristics, structure and equipment of this method, this article also introduces the recent work done by us to improve the measurement accuracy and the error analysis of the test equipment. The standard error of the test device measurement results can be controlled within 3%, in full compliance with the requirements of air conditioner specifications. We use this method for domestic and foreign more mature air conditioner was measured, the measured value and the nominal cooling capacity of the deviation is generally less than 5%. Due to the low cost of the method, the measurement is convenient and has a very high degree of specificity, it has been imitated by many units.
