DanCap (or Danfoss Capillary Tube Selector) is a utility designed to make calculations related to a capillary tube throttling device for a refrigeration system, with empirical formulas being used for this purpose.
According to the developers, the results returned by the utility are start values for optimization, values that are appropriate for the system to function. However, the results are not guaranteed to be the best when it comes to practice. The interface consists in a window, which displays the schema of the device and a calculator. Input data that can be changed include the type of refrigerant that is of interest to the user and parameters that are associated with it. These parameters are: heat load of the system, evaporating temperature, condensing temperature, return gas temperature. The "capillary tube recommendation" table, where results are returned to, has two columns, "length" and "diameter". Flow rate will also be returned in accordance with the input data.
Finally, DanCap is a utility aimed at those who are interested in the refrigerants offered by Danfoss for making certain calculations related to these products.
It shows the thermal design and sizing calculations of cooled heat exchangers.
It allows you to calculate the allowances for axial water swell.
