Description
Carbon Dioxide Refrigerant, Also Known As R744 Refrigerant, Refers To A Mixture Of Carbon Dioxide And Hydrocarbons As The Main Component Of The Refrigerant. Compared With Traditional Refrigerants, Carbon Dioxide Refrigerants Have The Characteristics Of Good Chemical Stability, Low Greenhouse Effect And Excellent Refrigeration Performance, And Are Widely Used In Automotive Air Conditioning, Cold Chain Logistics, Ice And Snow Sports And Other Fields.

WHAT ARE THE CHARACTERISTICS OF R744?
1. Does Not Destroy The Ozone Layer.
2. The Global Warming Potential (Gwp) Is 1.
3. Easy To Obtain (Can Be Obtained From Industrial Waste Gas) And Very Low Cost.
4. Harmless To Human Health And Living Environment, No Need To Recycle Or Reprocess.
5. Non-Toxic, Will Not Decompose Irritating Substances.
6. Non-Flammable And Non-Explosive.
7. Excellent Thermal Performance.
8. Co2 Refrigerant System Can Use Traditional Mineral Lubricants.
9. The Heat Dissipation Process Of Co2 System Under Outdoor Air Conditions In General Summer Is The Process Of Passing The Critical Point Or Exceeding The Critical Point. Since There Is No Actual Condensation, The Heat Exchanger Used For Heat Dissipation Is Called a Gas Cooler.
10. For The Same Gas Cooler Outlet Temperature, The Higher The Compressor Exhaust Pressure, The Greater The Cooling Capacity.
11. Low Compression Ratio. When The Condensation Temperature Of R-134a Is 50℃ And The Evaporation Temperature Is 0℃, The Compression Ratio Is 4.3. However, When The Outlet Temperature Of The Co2 Gas Cooler Is 37 ° C And The Evaporation Temperature Is 0 ° C, The Compression Ratio Is 2.6. At The Same Time, The Compression Ratio Of The Compressor Is Reduced, And The Compression Process Can Be Closer To Isentropic Compression To Improve Efficiency.
12. The Asymptotic Temperature Of The Gas Cooler Is Much Less Than 15~134°K.
13. For The Evaporator Of The Same Volume, The Co2 Pipe Diameter Is Small And The Number Of Pipe Rows Is Large.
14. Due To The High System Pressure, The Distribution Of Co2 Refrigerant In The Evaporator Is Relatively Uniform.
15. High Gas Density Can Reduce The Size Of The Pipe And Compressor Used, Making The System Light Weight, Compact Structure And Small Volume.

HOW TO STORE R744?
The Carbon Dioxide R-744 Refrigerant Steel Cylinder Is A Pressure Container, And Should Be Stored Away From Fire, Heat, And Direct Sunlight. It Is Usually Stored In a Cool, Dry And Ventilated Warehouse. When Handling, It Should Be Lightly Loaded And Unloaded To Prevent The Damage Of Accessories Such As Cylinders And Valves.
