Simple One Stage CO2 Cycle for Windows

Educational simulator for transcritical CO2 refrigeration

Simple One Stage CO2 is a free, educational application built to demonstrate transcritical CO2 refrigeration cycles. It’s intended as a hands-on learning aid for people studying thermodynamics or refrigeration engineering, offering a practical way to visualize how CO2 behaves in different refrigeration schemes.

Modes of cycle simulation

• Ejector-enhanced cycle (ejector-assisted operation)
• Gas-bypass configuration (bypass of discharge gas)
• Conventional single-stage arrangement (standard cycle)

Main learning advantages

This tool provides an interactive environment where users can change key parameters and immediately see how those changes affect system behavior. By experimenting with inputs such as pressures, temperatures, and component performance, learners can observe effects on efficiency, cooling capacity, and other performance metrics.

Who benefits from this tool

• Engineering students seeking a clear, practical introduction to CO2 refrigeration
• Technicians and professionals wanting a quick way to compare cycle variants
• Instructors who need an accessible demonstration tool for classroom use

Suggested alternative (free)

If you’re looking for another free option, consider SHAREit — a no-cost alternative that can be used alongside this simulator depending on your workflow and file-sharing needs.
