I go over Pressu Estimates vary, but CO2 refrigerant—known in HVAC parlance as R744—is yet another trick automakers can wield to increase efficiency and improve cooling performance, much like the dual benefits Carrier presents NaturaLINETM CO2 container refrigeration technology Posted on December 17, 2010 by r744 Carrier Transicold has announced the world’s first natural refrigerant technology for container refrigeration that takes advantage of a new marine-duty multi-stage CO 2 compressor. 2016-02-03 · This is post number eight of a series. Transcritical, cascade, and secondary CO2 systems This series continues with the introduction of transcritical, cascade and secondary systems; it explains how each system works; and then compares their advantages and disadvantages. Overview of Application Considerations for R744 The properties of R744 affect how the refrigerant is applied […] A NATURAL REFRIGERANT OVERVIEW Together with ammonia (NH3, R717) and hydrocarbons such as propane (R290), isobutane (R600a) and propylene (R1270), carbon dioxide (CO2, R744) is one of the most R744 (Dioxyde de carbone) Le R744, ou dioxyde de carbone, fait une nouvelle apparition dans le monde de la réfrigération industrielle. Alors qu’on a déjà cru qu’il s’agissait d’une matière inefficace qui demandait trop de pression pour être employée comme agent réfrigérant, les environnementalistes acclament maintenant le R744 comme une réponse à des préoccupations croissantes.

The CO2 is mainly recovered from fermentation processes in breweries and distillation plants. CRYOTEC also builds plants for recovering CO2 from waste process gases. In this case the recovered CO2 is used, for example, in the production of methanol. R744 är miljövänlig och har varken ozonnedbrytande potential (ODP) eller global uppvärmningspotential (GWP).

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). HFC systems always work subcritical because the condensing temperature never exceeds the critical temperature (e.g., 101 °C / 214 °F in the case of R134a). The R744 E-Compressor is a prototype that is still under optimization development.
