Refrigeration Capillary Tube Calculator

The name is a misnomer since the bore is too large to permit capillary action.
Refrigeration capillary tube calculator. As the throttling mechanism of the water chiller system the capillary tube is the simplest. Just click on the refrigerant line on the schematic and the line size dialog will appear. 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. How the capillary tube length effects the performance of the refrigeration system.
A capillary tube is 1 6 m long with an inside diameter generally fro m 0 5 2 mm. Capillary tube used as the throttling device in the domestic refrigerators deep freezers water coolers and air conditioners. When a capillary tube is sized to permit the desired flow of refrigerant the liquid seals its inlet. 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.
Once you have a system balance all that remains is to select line sizes and the tx valve or the capillary tube. This calculator uses the wolf and pate 2002 correlation. Chiller simulation program using the refsim framework. One of the most commonly used throttling devices for the refrigeration and air conditioning systems is the capillary tube.
It is a fixed length of the small diameter copper pipe usually with internal diameter from 1 16 to 1 8 inch. The result is a start value for optimization. Capillary tube sizing. If the system becomes unbalanced some vapour uncondensed refrigerant enters the capillary tube.
The start value will result in an acceptable operating system. Industrial refrigeration equipment chillers. This vapour reduces the mass flow of refrigerant considerably which increases condenser pressure and causes subcooling at the condenser exit and. Use our free online refrigerant capillary tube resizer calculator to do your calculations in a snap.
Capillary tube is the simplest of all devices of the account. This software allows the user to calculate the measurements of a capillary tube throttling device for a refrigeration system using empirical formulas. Capillaries generally refer to slender copper tubes with an internal diameter of 0 4 2 0 mm.
