FAQ

What refrigerant is used in the CO₂ Transcritical Refrigeration Compressor Unit?

The unit uses CO₂ (R744) as a natural refrigerant. CO₂ has a global warming potential (GWP) of 1 and zero ozone depletion potential (ODP), making it an environmentally responsible choice for refrigeration systems requiring compliance with modern refrigerant regulations.

What is the maximum operating pressure of this CO₂ compressor unit?

The CO₂ Transcritical Refrigeration Compressor Unit is designed for high-pressure transcritical operation. The high-pressure side can withstand operating pressures up to 16 MPa (160 bar), meeting the requirements of advanced CO₂ refrigeration systems.

Can the unit provide heat recovery?

Yes. The transcritical CO₂ refrigeration system can recover heat generated during the refrigeration process.

Depending on system design and operating conditions, the recovered heat can be used to produce hot water at approximately 80–85°C, providing additional energy value for applications requiring both cooling and heating.

Which applications are suitable for CO₂ Transcritical Refrigeration Compressor Units?

This unit is suitable for applications requiring efficient refrigeration and heat recovery, including:

• Supermarket refrigeration systems
• Cold chain logistics facilities
• Food processing plants
• Industrial heat pump systems
• Pharmaceutical temperature-controlled storage

What are the advantages compared with conventional refrigeration compressors?

Compared with conventional refrigeration compressors using synthetic refrigerants, CO₂ transcritical compressor units offer several advantages:

• Higher pressure capability for CO₂ refrigeration cycles
• Natural refrigerant with low environmental impact
• Heat recovery potential for combined cooling and heating systems
• Stable operation in demanding commercial and industrial applications
• Reduced dependence on high-GWP refrigerants

How does CO₂ transcritical technology improve energy efficiency?

CO₂ transcritical systems recover and utilize heat that would normally be wasted during refrigeration operation.

When combined with optimized compression control and proper system design, the technology can improve overall energy utilization, especially in applications requiring simultaneous cooling and hot water production.
