Refrigeration Capillary Tube Calculator

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.

Refrigeration capillary tube calculator.

The name is a misnomer since the bore is too large to permit capillary action. As the throttling mechanism of the water chiller system the capillary tube is the simplest. When a capillary tube is sized to permit the desired flow of refrigerant the liquid seals its inlet. The start value will result in an acceptable operating system.

Capillaries generally refer to slender copper tubes with an internal diameter of 0 4 2 0 mm. The program has a build in refrigerant line size calculator. 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. One of the most commonly used throttling devices for the refrigeration and air conditioning systems is the capillary tube.

Capillary tube is the simplest of all devices of the account. Industrial refrigeration equipment chillers. How the capillary tube length effects the performance of the refrigeration system. The result is a start value for optimization.

A capillary tube is 1 6 m long with an inside diameter generally fro m 0 5 2 mm. Chiller simulation program using the refsim framework. Capillary tube used as the throttling device in the domestic refrigerators deep freezers water coolers and air conditioners. This calculator uses the wolf and pate 2002 correlation.

Use our free online refrigerant capillary tube resizer calculator to do your calculations in a snap. This software allows the user to calculate the measurements of a capillary tube throttling device for a refrigeration system using empirical formulas. Just click on the refrigerant line on the schematic and the line size dialog will appear. It is a fixed length of the small diameter copper pipe usually with internal diameter from 1 16 to 1 8 inch.

Capillary tube sizing. Liquid refrigerant enters the capillary tube and as it flows through the tube the pressure drops because of friction and acceleration of the refrigerant. Refrigerant capillary tube resizer definition.
