Practical and theoretical evaluation of CO2 refrigeration
To avoid 2001-07-30 R744 (CO2) is refrigerant grade CO2, used as a replacement for R134a and R404A in ultra-low, low and medium temperature refrigeration applications. R744 (CO2) is becoming increasingly popular due to its excellent properties. With an Ozone Depleting Potential (ODP) of 0 and a Global Warming Potential (GWP) of 1, R744 (CO2) is a natural refrigerant. R744 (CO2) R-744 (carbon dioxide) is a refrigerant designed for industrial and commercial refrigeration applications. It can be used in direct expansion systems, in cascade refrigeration (sub-critical) with HFC or NH3 or HFO booster systems (trans-critical). 2017-11-22 R744 (CO2) is refrigerant grade CO2, used as a replacement for R134a and R404A in ultra-low, low and medium temperature refrigeration applications. R744 (CO2) is becoming increasingly popular due to its excellent properties.
Memmert has also committed itself to the use of natural, environmentally friendly refrigerants. R744 (CO2 carbon dioxide) R744 is pure carbon dioxide. You do not need an ARCTick refrigerant handling licence or a refrigerant trading authorisation to handle, sell or store this refrigerant. Main characteristics of R744 (CO2 carbon dioxide) R744 has a global warming potential (GWP) of 1 … Carbon dioxide (R744 or CO₂) refrigerant is increasingly being used in supermarket refrigeration applications, is utilised in hot water systems, and has the potential to be applied to smaller sealed unit applications. CO2 is non-flammable An assessment of the long term reliability of the R744 systems is made and future applications of R744 as a refrigerant are discussed.

operating pressures that are up to five times higher; 2. the solvent properties of R744 with respect to elastomers and 3. its low “critical temperature” of just 31°C, with the consequence that on hot days R744 can no longer be condensed by Secondary systems: The R744 is used as a secondary fluid and is pumped around the heat exchangers. Partial evaporation can occur because of the volatility of R744, but saturated refrigerant will exit the evaporator (i.e.

The chart in figure 5 compares the pressure of R744 with R404A and R134a. Figure 5. Pressure-temperature relationship comparison The saturation curve for R744 does not extend beyond 31°C because this is the critical point - above this condition Co2 Refrigerant R744 - YouTube. R744 Peculiarity's and Terminologies. I apologies in advance for my rough drawings.
The refrigerant CO2, also known in the air conditioning industry as R744, was already known before 1900. Due to the environmentally harmful properties of synthetic refrigerants, it has been experiencing a renaissance for several years.
