Pack Calculation II 3.06

Pack Calculation II is a refrigeration and heat pump system simulation tool developed by IPU. It helps engineers, consultants, and operators model compressor rack (“pack”) systems—especially for supermarkets and commercial/industrial refrigeration—estimate performance across operating conditions, and compare design alternatives over a full year using climate data and load profiles. The software supports a wide range of refrigerants, including transcritical CO2 and conventional HFC/HFO options, and covers common system architectures such as single- and two-stage packs, CO2 booster systems, parallel compression, subcooling, and heat recovery.

Key capabilities:

• Annual energy analysis using weather data and user-defined load profiles
• Performance metrics including capacity, power input, COP, and operating conditions
• Comparison of alternative system designs, controls, and setpoints
• Modeling of CO2 systems alongside traditional refrigerants
• Result visualization and export for documentation and reporting

Designed for practical design support and benchmarking, Pack Calculation II streamlines early concept evaluation and helps quantify the energy and cost implications of system choices before installation.

Pack Calculation II is developed by IPU. The most popular version of this product among our users is 3.0. The name of the program executable file is PackCalculationII.exe.
