Capillary Tube Selection Software

Introduction-
This software allows the user to calculate a capillary tube throttling
device for a refrigeration system based on empirical formulas.
The result is a start value for optimization, this start value
typically giving a functioning system.
In certain cases the best possible choice of capillary diameter and
length might deviate remarkably from this calculated result.


The capillary sizing is based on the assumption, that
- the suction line is connected to the capillary tube in most of its length for internal heat exchange
- no or little subcooling appears in continuous operation

The refrigerant used is to be chosen from a list.
Input values should be representative dimensioning values for the refrigeration system.
The input value for
- capacity is to be taken for the also to be input operating conditions, in terms of
- evaporating temperature
- condensing temperature
- return gas temperature and
- without subcooling
for the compressor type used, preferably.
The input data are limited per refrigerant according to experience and compressor application areas.

Data like these could be according to data sheet performance data at ARI 540, EN 12900 or CECOMAF conditions, or taken from a software selection tool like Danfoss RS™.

The list of capillary tube inner diameters does contain typically available
sizes from different countries. They will not all be available at one place.
A length value for an available diameter size is to be chosen by the user,
or guessed, if not listed.

The list of refrigerants and capillary tube diameters and the calculation formulas and limits might be altered at updates, based on new experience.


Installation and requirements-

The DanCap™ software can be installed from harddisk, network drive, or CDROM.
Setup will ask you for destination directory and will be used for installation and later de-installation, if needed. De-installation removes the software again, completely, and very accurate, according to our experience.

please download in hire

System requirements-

Min. 200 MHz Pentium® or compatible
32 MB RAM min., 64 MB recommended
15 MB harddisk space
Microsoft Windows 95®, 98, ME, XP, NT 4.0, 2000 or newer
