Please note: The below featured PC software is end of life. The latest version of CapSel is part of the new Secop Toolkit which also provides more features in one App. The Secop Toolkit App is now available for devices running on Apple’s iOS or Google’s Android operating systems.
Secop Toolkit is also accessible by clicking on the image Secop Toolkit Web App below.
Secop was formerly known as Danfoss Compressors. Our first selection program DanCap was developed in 2006 and is no longer supported. It was renamed to CapSel in 2012. As we update our software to reflect our current knowledge and experience, the CapSel program will showing improved calculation results compared to the old DanCap program.
This software allows the user to calculate the measurements of a capillary tube throttling device for a refrigeration system using empirical formulas. The result is a start value for optimization. The start value will result in an acceptable operating 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 capillary and suction line is connected to in min. 1 m to make internal heat exchange between liquid and suction gas.
The refrigerant used is chosen from a drop-down list. Input values should be representative values for the refrigeration system. The input values are:
The input data are limited per refrigerant according to experience and compressor application areas.
Data such as these could reflect data sheet performance data at ARI 540, EN 12900, or CECOMAF conditions, or others.
The list of capillary tube inner diameters typically includes available sizes from different countries. They will not all be available on one place. A length value for an available diameter size is to be chosen by the user, or estimated, if not listed.
The list of refrigerants and capillary tube diameters and the calculation formulas and limits could be adapted through updates, based on new experience.
Database update 2.2 (2019):
Unzip and run "Setup.Exe". Former versions (e.g. DanCap™) must be uninstalled first.
This software allows the user to calculate the heat load of a given application. Heat load is the amount of heat that must be removed from the cabinet (box) in order to maintain the target temperature.
It does not take into account if the load is different in a pulldown situation, e.g. during initial start or pulldown after defrost. The heat load will vary with changes in ambient temperature.
The philosophy behind the program is that basic input parameters are known to everyone, and no deeper knowledge of refrigeration is required.
Input
The input values below are the minimum required to calculate the heat load
In addition, “check boxes” can be opened for entering additional inputs and loads. See picture of extended view.
Calculations
The heat load calculation is based on the formula:
Q = k × A × Δt (heat load = k-value × heat transfer area × delta t)
Units
It is possible to choose between different input units.
Context Help
For certain input values, an “I” in a blue circle indicates that holding the cursor over the “I” will display an additional explanation in a pop-up window.
Selecting the Compressor
After entering the input values, the compressor selection parameters will be calculated and shown.
By clicking “Product Selection”, you will be guided directly to the Product Selector where the proper compressor can be selected.
Unzip and run "Setup.Exe".
