Pack Calculation Pro
About
Pack Calculation Pro is designed to compare different system designs, control strategies and refrigerants for your refrigeration or heat pump project, by calculating yearly energy consumption, as well as Life Cycle Costing (LCC) and Total Equivalent Warming Impact (TEWI).
We kick-start your calculations by reducing the amount of data you should provide, among others by using load profiles and weather data to calculate the performance. We also select well-proven default values for most coefficients and parameters, though you can always customize the preferences, and import your own load profile data, to meet your specific needs.
Our comprehensive database of real compressors, maintained in cooperation with OEMs*, makes it possible to compare performance of different products using a single definition for the operating conditions.

Download Pack Calculation Pro – 5.2.5 – (May 9th 2022)
v5.2.5:
- Fix crash during plotting, when heat pump unable to resolve evaporation temperature
- Fix two bugs causing over-estimated power consumption for parallel compressors, especially at low parallel pack capacity
- Fix crash when using free cooling on 64-bit version
- Fix to selecting multiple R1234ze(E) compressors in pack
Version 5.2 (2022-03-14) introduces:
- Add ‘One-stage transcritical, ejector‘ model
- Add ‘Two-stage Cascade heat pump‘ model
- Frascold: Import 511 new CX and SRC compressors for R134a, R290, R448A, R449A, R513A, R1234ze(E)
- Bitzer: Import 837 new 60 Hz compressors, 365 new 50 Hz compressors, and update 472 existing 50 Hz compressors. CSH/CSW/HHK/HS/OHK/OS families
- Fix: CO(S)P calculation for heat pumps in plots and exports now based on condensing capacity – these were based on evaporator capacity until now. Now COSP values align properly with Average COP in Summary.
v5.1 introduced:
- Several instabilities in Cooling Tower calculations fixed, including application crashes in the 64-bit version. Only affects under-dimensioned cooling towers – so simulations that before ran without warnings will still return same results.
- Fixed unit of mWater and VAir coming from calculations, data was in kg/s and m3/s respectively, but is now in kg/h and m3/h to fit with nomenclature. Affects all simulations with cooling tower
- Bug fixes regarding simulation of variable speed parallel compressors
- Improvements to memory usage.
v5.0 (2021-04-21) introduced:
- Long-awaited refrigerants: R32, R448A, R449A, R450A, R513A, R1234yf, R1234ze(E)
- Automatic check for updates, which can help you keep up to date. You still have to download + install yourself though.
- Parallel compression and bypass valve can now operate simultaneously, making these simulations more realistic.
For a full overview of the changes, check the release notes (v5.2), as well as the upgrade notes in the user manual (v5.2).
Please note that from version 5.0, personal use requires registration. See activation instructions for personal use.
