Refrigeration Capillary Tube Calculator

Refrigerant capillary tube resizer definition.

Refrigeration capillary tube 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. 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. The name is a misnomer since the bore is too large to permit capillary action.

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

Just click on the refrigerant line on the schematic and the line size dialog will appear. The program has a build in refrigerant line size calculator. As the throttling mechanism of the water chiller system the capillary tube is the simplest. This vapour reduces the mass flow of refrigerant considerably which increases condenser pressure and causes subcooling at the condenser exit and.

Capillaries generally refer to slender copper tubes with an internal diameter of 0 4 2 0 mm. Capillary tube sizing. This calculator uses the wolf and pate 2002 correlation. It is a fixed length of the small diameter copper pipe usually with internal diameter from 1 16 to 1 8 inch.

A capillary tube is 1 6 m long with an inside diameter generally fro m 0 5 2 mm. Industrial refrigeration equipment chillers. One of the most commonly used throttling devices for the refrigeration and air conditioning systems is the capillary tube. If the system becomes unbalanced some vapour uncondensed refrigerant enters the capillary tube.

The result is a start value for optimization. When a capillary tube is sized to permit the desired flow of refrigerant the liquid seals its inlet. Capillary tube used as the throttling device in the domestic refrigerators deep freezers water coolers and air conditioners.
