As a result, working with R744 will require new service equipment meeting the relevant SAE standards, as well as technical training about the major differences. The decision by some automotive manufacturers to adopt R744 came from flammability concerns about R1234yf, particularly Mercedes-Benz parent company Daimler.

Yes, as we all know one of the very first steps when it comes to diagnosing a refrigeration … For commercial refrigeration and industrial conditioning plants using CO 2 (R744) For up to 140 bar. COMMERCIAL REFRIGERATION ROXSTAair By TEKO Liquid carbon dioxide (industry nomenclature R744 or R-744) was used as a refrigerant prior to the discovery of R-12 and may enjoy a renaissance due to the fact that R134a contributes to climate change more than CO 2 does. Its physical properties are highly favorable for cooling, refrigeration, and heating purposes, having a high volumetric Solid R744 (also known as dry ice) has a surface temperature of -78.5 °C (-109.3 °F). 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.

The theoretical cycle performance of R410A and R744 is compared on the basis of the comfort of the conditioned space, which is determined by dehumidification in cooling mode and the supply air temperature in heating mode. R744 has some very attractive properties, which makes it destined to be used as a working fluid. Peter Neksa has already proved the advantages of using R744 for water and space heating applications.

The present study is a theoretical analysis of a two-stage transcritical cooling cycle using R744 (carbon dioxide) as a refrigerant.
