Refrigeration Capillary Tube Calculator

Just click on the refrigerant line on the schematic and the line size dialog will appear.

Refrigeration capillary tube calculator. This calculator uses the wolf and pate 2002 correlation. Industrial refrigeration equipment chillers. The name is a misnomer since the bore is too large to permit capillary action. 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.

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. As the throttling mechanism of the water chiller system the capillary tube is the simplest. Once you have a system balance all that remains is to select line sizes and the tx valve or the capillary tube. When a capillary tube is sized to permit the desired flow of refrigerant the liquid seals its inlet.

Capillaries generally refer to slender copper tubes with an internal diameter of 0 4 2 0 mm. Use our free online refrigerant capillary tube resizer calculator to do your calculations in a snap. This vapour reduces the mass flow of refrigerant considerably which increases condenser pressure and causes subcooling at the condenser exit and. If the system becomes unbalanced some vapour uncondensed refrigerant enters the capillary tube.

A capillary tube is 1 6 m long with an inside diameter generally fro m 0 5 2 mm. The start value will result in an acceptable operating system. Capillary tube is the simplest of all devices of the account. Capillary tube used as the throttling device in the domestic refrigerators deep freezers water coolers and air conditioners.

Chiller simulation program using the refsim framework. Refrigerant capillary tube resizer definition. The program has a build in refrigerant line size calculator. How the capillary tube length effects the performance of the refrigeration system.

Capillary tube sizing. The result is a start value for optimization. It is a fixed length of the small diameter copper pipe usually with internal diameter from 1 16 to 1 8 inch.
