Liquid refrigerant enters the capillary tube and as it flows through the tube the pressure drops because of friction and acceleration of the refrigerant.
Refrigeration capillary tube calculator.
Capillaries generally refer to slender copper tubes with an internal diameter of 0 4 2 0 mm.
One of the most commonly used throttling devices for the refrigeration and air conditioning systems is the capillary tube.
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.
When a capillary tube is sized to permit the desired flow of refrigerant the liquid seals its inlet.
This vapour reduces the mass flow of refrigerant considerably which increases condenser pressure and causes subcooling at the condenser exit and.
The start value will result in an acceptable operating system.
If the system becomes unbalanced some vapour uncondensed refrigerant enters the capillary tube.
Once you have a system balance all that remains is to select line sizes and the tx valve or the capillary tube.
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.
Just click on the refrigerant line on the schematic and the line size dialog will appear.
This software allows the user to calculate the measurements of a capillary tube throttling device for a refrigeration system using empirical formulas.
How the capillary tube length effects the performance of the refrigeration system.
It is a fixed length of the small diameter copper pipe usually with internal diameter from 1 16 to 1 8 inch.
Refrigerant capillary tube resizer definition.
Industrial refrigeration equipment chillers.
The program has a build in refrigerant line size calculator.
Capillary tube is the simplest of all devices of the account.
Use our free online refrigerant capillary tube resizer calculator to do your calculations in a snap.
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.
This calculator uses the wolf and pate 2002 correlation.
