CO2 200 Transcritical Systems

CO2 200 — Transcritical R744 Applications

Audience
Industrial refrigeration technicians, engineers, and project personnel working with transcritical R744 systems who need application‑level system understanding.

Value
CO2 200 explains how transcritical R744 systems are assembled, controlled, and applied in real facilities. Rather than focusing on component theory, the course shows how compressors, gas coolers, receivers, intercoolers, and control loops work together to support low‑temperature refrigeration, heat recovery, and operational flexibility.

What’s Included
Participants learn how two‑stage transcritical systems are configured, why specific control strategies are used, and how R744 applications differ from ammonia systems at the facility level. The course also introduces optional features such as parallel compression, mechanical subcooling, and ejector defrost, with guidance on where each makes sense.

Course Sections

• Two‑Stage TC System Overview – Architecture and design intent
• High Stage Compressors – Transcritical compression and defrost support
• Gas Cooler – Heat rejection and pressure control
• System Receiver – Refrigerant storage and expansion control
• Intercooler – Mass flow balancing between stages
• Low Temp Suction Accumulator – Compressor protection
• Low Stage Compressors – Subcritical low‑temperature operation
• Transcritical Applications – Where R744 performs best
• A Natural Decision: R717 vs R744 – Application‑level comparison
• Features and Options – Enhancements for efficiency and flexibility

Outcome
After completing CO2 200, participants will understand how transcritical R744 systems are applied in real installations and will be prepared to support operation, troubleshooting, and advanced system training.
