FrigoSim 2.5

FrigoSim by Thorbergsen Frigosoft is a professional simulation and design suite for refrigeration, HVAC, and heat pump systems. It helps engineers, designers, and educators build, analyze, and optimize vapor-compression cycles and advanced architectures before committing to prototypes or field trials. With an intuitive model builder, an extensive refrigerant library, and engineer-grade analytics, FrigoSim turns complex thermodynamics into confident, data-driven decisions.

Key capabilities:

• Component-level modeling: compressors, condensers, evaporators, expansion devices, heat exchangers, receivers, accumulators, piping, valves, fans, and pumps
• Cycle types: single-stage, multi-evaporator, subcooling and economizer loops, cascade and booster systems, CO2 transcritical, secondary loops, and heat pumps/chillers
• Analyses: steady-state and transient studies, parametric sweeps, sensitivity analyses, load profiles, defrost cycles, variable-speed control, and capacity modulation
• Refrigerants: a built-in library of common and low-GWP refrigerants and blends with property calculations; support for custom fluids and user-defined mixtures
• Performance metrics: capacity, COP/EER, power draw, discharge temperatures, superheat/subcooling, pressure drops, compressor map interpolation, and system stability indicators
• Psychrometrics: air-side coil and space-load calculations including humidity, dew point, and comfort metrics
• Optimization: automatic sizing and target-based optimization for efficiency, cost, or mass flow, with multi-objective trade-off curves
• Visualization: interactive P–h, T–s, and Mollier charts, system schematics, trend plots, and exportable figures and datasets
• Reporting and integration: one-click professional reports with assumptions, results, and diagrams; CSV/Excel exports and an optional API for workflow integration
• Units and conventions: SI and IP units, configurable reference states, and customizable safety limits and alerts
• Workflow: project templates, reusable component libraries, versioned scenarios, and robust undo/redo

Who it’s for:

• Refrigeration and HVAC engineers
• Equipment manufacturers and OEMs
• Researchers and students in thermal sciences
• Energy consultants and commissioning teams
