Refrigeration Devon

CoolHeat Southwest Ltd is one of the leading suppliers and installers of carbon dioxide (CO2) refrigeration systems in the Southwest, helping to reduce your potential carbon emissions and energy costs while increasing your efficiency. Here are some advantages of using carbon dioxide as a refrigerant:

• Carbon dioxide is environmentally benign, non-toxic, and non-explosive.
• It is significantly less expensive than synthetic refrigerants.
• Carbon dioxide is non-corrosive with most materials and has good miscibility with compressor lubricants for oil return.
• It has a high volumetric efficiency, allowing for smaller pipe sizes and compressor swept volumes compared to equivalent HFC systems.
• The effect of pressure drop in pipelines is less noticeable with carbon dioxide than with HFC refrigerants.
• Carbon dioxide offers much higher heat transfer efficiency, enabling heat exchangers to be smaller or operate at a lower temperature difference compared to equivalent HFC units.
• Transcritical carbon dioxide systems are designed for higher pressures and equipped with pressure relief valves that do not discharge when the power is turned off or if the equipment shuts down for any reason.
• These systems also operate at very high discharge temperatures, providing better opportunities for efficient heat recovery than equivalent HFC systems.
• Carbon dioxide is a stable molecule, which results in a low potential for decomposition within the refrigeration system.
• There is no forthcoming legislation phasing out carbon dioxide as a refrigerant, making it a viable long-term option with significant potential to reduce companies’ carbon footprints.
