Refrigeration Capillary Tube Calculator

It is a fixed length of the small diameter copper pipe usually with internal diameter from 1 16 to 1 8 inch.

Refrigeration capillary tube calculator.

This calculator uses the wolf and pate 2002 correlation. Chiller simulation program using the refsim framework. 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.

Refrigerant capillary tube resizer definition. Use our free online refrigerant capillary tube resizer calculator to do your calculations in a snap. One of the most commonly used throttling devices for the refrigeration and air conditioning systems is the capillary tube. How the capillary tube length effects the performance of the refrigeration system.

Once you have a system balance all that remains is to select line sizes and the tx valve or the capillary tube. Capillary tube sizing. As the throttling mechanism of the water chiller system the capillary tube is the simplest. The name is a misnomer since the bore is too large to permit capillary action.

The result is a start value for optimization. Liquid refrigerant enters the capillary tube and as it flows through the tube the pressure drops because of friction and acceleration of the refrigerant. Capillary tube is the simplest of all devices of the account. If the system becomes unbalanced some vapour uncondensed refrigerant enters the capillary tube.

Just click on the refrigerant line on the schematic and the line size dialog will appear. 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. This vapour reduces the mass flow of refrigerant considerably which increases condenser pressure and causes subcooling at the condenser exit and.

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