摘要
本文自行设计、安装和调试了一个小型制冷实验装置,并且在此小型制冷装置上进行绝热毛细管流动过程的实验研究。详细阐述了实验系统的设计,各个部件的机构以及制作工艺。利用此实验装置测量了制冷剂R22的替代制冷剂R134a、R407C和R410A在毛细管中的流动参数,并与已经过验证的绝热毛细管数学模型的计算结果进行了比较,实验值与计算值吻合良好。
In this paper,a small experimental refrigerator was designed and fabricated.And study on the flow behavior in the adiabatic capillary tube was made using this experimental refrigerator. The design of the refrigerator,the structures of parts and production process were introduced in detail.The flow parameters of R134a,R407C and R410A,alternatives to R22,were measured by this experimental device.Experimental results are in a good agreement with the proven results calculated from the mathematical model of adiabatic capillary tube.
