Refrigeration Capillary Tube Calculator

This software allows the user to calculate the measurements of a capillary tube throttling device for a refrigeration system using empirical formulas.

Refrigeration capillary tube calculator.

When a capillary tube is sized to permit the desired flow of refrigerant the liquid seals its inlet. It is a fixed length of the small diameter copper pipe usually with internal diameter from 1 16 to 1 8 inch. The name is a misnomer since the bore is too large to permit capillary action. The capillary tube is made up of copper and it has very small diameter ranging from 0 5 to 2 28 mm 0 020 to 0 09 inches.

Refrigerant capillary tube resizer definition. The start value will result in an acceptable operating system. Liquid refrigerant enters the capillary tube and as it flows through the tube the pressure drops because of friction and acceleration of the refrigerant. A capillary tube is 1 6 m long with an inside diameter generally fro m 0 5 2 mm.

Just click on the refrigerant line on the schematic and the line size dialog will appear. Industrial refrigeration equipment chillers. One of the most commonly used throttling devices for the refrigeration and air conditioning systems is the capillary tube. Use our free online refrigerant capillary tube resizer calculator to do your calculations in a snap.

Capillaries generally refer to slender copper tubes with an internal diameter of 0 4 2 0 mm. The refrigerant capillary tube is a vital component to a refrigerator or air conditioner because it condenses the amount of refrigerant supplied to the evaporator. If the system becomes unbalanced some vapour uncondensed refrigerant enters the capillary tube. Chiller simulation program using the refsim framework.

This calculator uses the wolf and pate 2002 correlation. Once you have a system balance all that remains is to select line sizes and the tx valve or the capillary tube. Capillary tube is the simplest of all devices of the account. Capillary tube sizing.

The result is a start value for optimization. The program has a build in refrigerant line size calculator. Capillary tube used as the throttling device in the domestic refrigerators deep freezers water coolers and air conditioners.
