本文建立了绝热毛细管稳态数学模型,提出了一种毛细管长度的计算方法,并针对不同工质进行了计算。计算结果表明,相同工况下,R290/R600a制冷剂需要的毛细管长度比R12制冷剂长。
In this paper, a steady-state mathematic model of adiabatic capillary was established, and a method to calculate the capillary length was proposed. The calculation was made for different working fluids. The calculation results show that the R290 / R600a refrigerant needs longer capillary length than the R12 refrigerant under the same conditions.
