CO2 as a Refrigerant — Five Potential Hazards of R744 by emersonadmin on July 2, 2015 This is post number five of a series, and continues our overview of CO2 as a refrigerant by touching on the potential hazards associated with handling systems where R744 is present. R744 Hazards

Ideal for R744 medium temperature cascade and booster systems, Stream CO2 compressors have a design pressure of 135 bar. Optimized refrigerant flow and heat transfer yield best performance. R-744 Transcritical R-744 Subcritical Copeland Scroll™ ZO Compressors Title: EcoSEPTEMBER.indd Created Date: 8/31/2004 11:02:53 AM R744, or carbon dioxide, is making its re-entry into the industrial refrigeration scene. Once thought to be a wasteful chemical requiring too much high pressure to be feasible as a coolant, environmentalists now hail R744 as an answer to growing concerns. technology and system components allow R744 (CO 2) to reach competitive efficiency levels for transcritic cycle especially in northern countries and for sub-critic cascade cycle in southern countries. Carbon Dioxide, CO2 (R744) was one of the first commonly applied working fluids in the infancy of refrigeration more than 100 years ago. the current threshold to introduce R744 technology can This is post number seven of a series.

By Alec Johnson May 19, 2019 R-744 Carbon Dioxide is one of the oldest refrigerants in the world. Its first usage can be traced all the way back to the nineteenth century. Before the popularity of CFC and HCFC refrigerants Carbon Dioxide was one of the most widely used refrigerants.

With an Ozone Depleting Potential (ODP) of 0 and a Global Warming Potential (GWP) of 1, R744 (CO2) is a natural refrigerant. A-Gas only sources CO2 that is recovered and not produced, so no new CO2 enters the atmosphere, helping you reduce your carbon footprint further.

The list of disadvantages appears smaller than the advantages list, but these issues should not be overlooked, as they have a significant impact on the safety and reliability […] CO2 as a Refrigerant — Five Potential Hazards of R744 by emersonadmin on July 2, 2015 This is post number five of a series, and continues our overview of CO2 as a refrigerant by touching on the potential hazards associated with handling systems where R744 is present. R744 Hazards R744 (CO 2) is a leading option for environmental reasons, and it can be a winner for power consumption as developments of component technology and application methods continue to reveal potential performance gains. Good experience has been gained with different system configurations over many years, particularly in central and northern Europe. R744 systems work subcritical when the condensing temperature is below 31 °C (88 °F). R744 systems work transcritical when the gas cooler exit temperature is above 31 °C (88 °F).
