This is post number five of a series, and continues our overview of Aug 24, 2015 They compared 12 typical refrigeration systems currently offered for ice arenas in the market, and found that a CO2/R744 system as being the R744 is pure carbon dioxide.

But, unlike other natural refrigerants, there is not a safety concern. With hydrocarbons you have the flammability risk, with Ammonia you have the toxicity risk, but with CO2 the safety risk is minimal.

Leading bus manufacturers already launched the first models with R 744 air conditioners. The refrigerant used in Memmert ICH eco /ICP eco appliances with the abbreviation R744 and the chemical molecular formula CO 2 has a GWP value of 1 and is therefore almost climate-neutral.

Its environmental advantages ( GWP of 1, non-ozone depleting, non-toxic, non-flammable) could make it the future working fluid to replace current HFCs in cars, supermarkets, and heat pump water heaters, among others. CO2 refrigerant – R744 It is ever more likely that CO2 (carbon dioxide) will be the refrigerant used by many manufacturer’s in the near future. Daimler (owner of the Mercedes brand) and the VAG group are already using CO2 in some of their models and it is thought it could become the way forward for many others. 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 The term R744 refers to CO 2 when it is used as natural refrigerant in the refrigeration and air conditioning industry.
Therefore BOC offers refrigerant grade R744 carbon dioxide. This product has extremely low levels of moisture, normally below 10ppm by weight.

Heat pumps, Heatrecovery, Energysaving - R744
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. Tap to unmute.

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.
Practical and theoretical evaluation of CO2 refrigeration
Impianti a CO 2: pro & contro Vantaggi e svantaggi dell'uso nella refrigerazione Anidride carbonica - R744 - Uso 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. 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 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) Un autre réfrigérant alternatif utilisé est le dioxyde de carbone (R744) d'origine naturelle qui est considéré comme étant très écologique et présente un très faible GWP de seulement 1.
It uses a simple “traffic light” system and employs the common HFCs, such as R404A and R134a as a baseline. 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 refrigeration, and mobile air conditioning. The refrigerant is carbon dioxide (CO2), also called R744 in this application. The compressor drives the flow of CO2 through the cycle and raises the pressure above the critical pressure.
