Abstract: Traditionally, capillary tubes are designed for CFC12 and HCFC22 as working fluids.Due to the public concerns on the depletion of the ozone layer and greenhouse effect, CFCs and HCFCs are falling into disuse.As a result, a number of natural refrigerants including HC600a, HC290 and a mixture of HC290 and HC600a.etc,have emerged as promising CFC-free alternatives to CFCs.Characteristic of the flow of such natural refrigerants in a capillary is analyzed, and a adiabatic homogenous model accounting for the metastable phenomenon is established to simulated the flow of natural refrigerants in a capillary in this paper.The results agree well with the experimental data that verified the model established in this paper.
