If the capillary tube is too long or too small diameter, or both, of the evaporator will be sorely lacking refrigerant and too liquid refrigerant will be stored in the capacitor. The combined effect will be to make the system work at too high a pressure, and with insufficient cooling capacity.Capillary tube calculations - refrigeration-engineerJan 05, 2009Does anyone know of a software / freeware program that will calculate the replacement length of a capillary tube. I have the Danfoss program for sizing new tubes but cannot locate anything for cross referencing. The paper charts never seem to cover all the sizes. ChillCapillary tube size! - Refrigeration EngineerJun 04, 2009If you did indeed use the 1.77m length then the quality at the entrance to the tube would be 0.46 and you will lose a lot of performance. Other sites suggest lengths from 4 to 6 metres which seem more appropriate - one site suggests 7.8m but this may be too long for start up loads on the compressor.

It doesnt have any moving parts so there is increase in refrigeration effect when capillary tube The Effect of Capillary Tube Length on the Refrigeration Jul 31, 2019The capillary tube is warm. If they are joined together the suction line will get a little warmer (more superheat) and the capillary tube will get a little cooler (more subcooling). The extra subcooling in the cap tube does slightly increase efficiency, although the warmer suction gas is harder on the compressor. It's a trade off.
