The evaporator pressure is at kept at around 3.5 MPa and the gas cooler pressure is nominally around 10 MPa, which is above the CO2 (R744) critical pressure of 7.4 MPa. Hence, this is a transcritical refrigeration cycle. The gas cooler pressure changes in response to changing environment temperature. OTRA ALTERNATIVA: R744 (DIÓXIDO DE CARBONO) Como otra opción de refrigerante también se emplea el dióxido de carbono (R744), que se halla en la naturaleza y que está considerado especialmente respetuoso con el medio ambiente, ya que presenta un GWP de sólo 1. Sin embargo, las propiedades Stazione di ricarica automatica per impianti A/C di veicoli che utilizzano il refrigerante R744 (CO2). Estremamente precisa grazie al misuratore di concentrazione CO2. Kohlenstoffdioxid ist ein unbrennbares, saures und farbloses Gas; bei niedrigen Konzentrationen ist es geruchlos, bei hohen Konzentrationen nimmt man einen scharfen bis sauren Geruch wahr, wobei es auch hier (ähnlich wie z. B. bei Blausäure) Personen gibt, die diesen Geruch nicht wahrnehmen können. Attrezzatura R744 (CO2) Descrizione Categoria.

It is a naturally occurring substance that can be applied as a working fluid in different heating and cooling applications, due to its excellent heat transfer properties and its high volumetric cooling capacity. R744 (CO 2) Refrigerant Cooling Systems, the Finned Tube R744 (CO 2) By Friterm, published Jun 30, 2011 - 24 pages R744 (CO 2) was used in the early stages of the refrigeration industry, but it lost the competition with halocarbon R744 (Carbon dioxide) R744 (Carbon dioxide) R744 is environmentally friendly, having zero ODP (Ozone Depletion Potential) and minimal GWP (Global Warming Potential). R744 (Carbon dioxide) R744 is environmentally friendly, having zero ODP (Ozone Depletion Potential) and minimal GWP (Global Warming Potential). It also has excellent thermodynamic properties and low energy usage making it suitable for a range of applications such as industrial heat extraction, chilled warehousing, shipping vessels, commercial R744 Hazards R744 is not flammable, but its high pressures, toxicity at high concentration, and potential for dry ice 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.
