Özet

Capillary tubes are used widely in small refrigeration systems. It is necessary to design the capillary tribe, but there does not exist any analytical equation which allows the determination of capillary tube length or mass flow rate for all refrigerants. In this work, an analytical equation is derived which allows to design the capillary tubes. The comparison with existing methods and experimentally obtained values using the refrigerants R12, R22 R113, R114, R134a, and R600a has turned out to be satisfactory.
