摘　　要：根据部分已知的空气状态参数,通过查阅焓-湿图表可粗略估算出未知的空气状态参数。工程施工或精度要求不高的情况下,该方法能满足要求;但在精度要求比较高的情况下,尤其是在空调产品检测和高精度试验时,依靠查阅图表的方法就不能满足要求了。本文结合空气状态参数计算软件,论述了空气状态参数的高精度计算方法,并着重介绍了为此而专门编写的计算机算法。Generally, we can measure several air properties directly, such as dry-bulb temperature, wet-bulb temperature, and barometric. Using the psychrometric chart with these data, we can get the other air properties inaccurately. The above - mentioned mothod of air property calculation is enough for generic application, but not enough for the specific application that need high accuracy, such as the capacity test of air conditioner, because of its big error amount. Consequently we need the better calculation to meet the high precision. A accurate calculation of air property has been discussed.
