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.

Summary. These are bilingual booklets 30 May 2018 2) R-134a and R744 ac system components are so different in size and pressure ratings that I doubt this conversion would be feasible. And its Refrigerant R744 (CO2) Properties of Saturated Liquid and Saturated Vapour. gymnast_on_head.png reverse. Pressure, Density, Volume, Enthalpy, Enthalpy Eight configurations were studied: a R744/R134a cascade refrigeration system ( baseline), a conventional and an improved R744 booster system, two R744. The present study is a theoretical analysis of a two-stage transcritical cooling cycle using R744 (carbon dioxide) as a refrigerant. The effect of the intercooling R744 (CO2) is refrigerant grade CO2, used as a replacement for R134a and R404A in ultra-low, low and medium temperature refrigeration applications.

En annan aspekt av transkritisk R744-cykel är förmågan att återgå till konventionell ångkomprimeringscykel under förhållanden med låg omgivningstemperatur. De olika alternativen DX R407F, DX R448A,. Indirekt R290 (propan) och DX R744 (CO2) sprider sig dock ordentligt i investeringskostnader.

If R744 is at a pressure higher than the triple point and the pressure is reduced to below the triple point (e.g., to atmospheric pressure), it will deposit directly to solid. Regardless of what system you are working on rather it is a home air conditioner, a vehicle’s air conditioner, a supermarket refrigeration system, or a large scale industrial application they all have one thing in common: Pressure. Yes, as we all know one of the very first steps when it comes to diagnosing a refrigeration … led to the revival of R744 in parts of the European refrigeration market. Regionally, this trend is reinforced by legislation and taxation schemes which favor the usage of refrigerant R744. In comparison with HFC refrigerants, the specific properties of R744 require changes in the design of the refrigeration system.
