The term R744 refers to CO 2 when it is used as natural refrigerant in the refrigeration and air conditioning industry. R744 CO 2 has excellent thermodynamic properties and has significant advantages compared to classical and other alternative refrigerants: R744 refrigerant properties: CO 2 is non-corrosive, non-toxic and non-flammable

You do not need an ARCTick refrigerant handling licence or a refrigerant trading authorisation to handle, sell or store this refrigerant. Main characteristics of R744 (CO2 carbon dioxide) R744 has a global warming potential (GWP) of 1 and is non-flammable. 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.

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. has some additional technical requirements to other conventional refrigerants.

KONFORT 744. The perfect solution for servicing and recharging. the new CO2 air conditioning systems. TEXA is universally recognised as one of the undisputed leaders in equipment for garages and vehicle repair shops. TEXA’s product range includes diagnostic tools, exhaust gas analysers and air conditioning system servicing and recharging stations.

With an Ozone Depleting Potential (ODP) of 0 and a Global Warming Potential (GWP) of 1, R744 (CO2) is a natural refrigerant. Linde’s cylinders are specially prepared so that our R744 has very low moisture content and low non condensable gas content. Typically, Linde’s R744 is a high purity gas that is over 99.99% pure, with a moisture content of less than 10 parts per million (by weight). Due to the extra work involved in meeting the demanding specification for R744, refrigerant grade CO This plot shows the pressure and temperature at different points in the cycle. 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. Carbon Dioxide (R744) - The New Refrigerant Introduction and Discussion In the early days of refrigeration the two refrigerants in common use were ammonia and carbon dioxide. Both were problematic - ammonia is toxic and carbon dioxide requires extremely high pressures (from around 30 to 200 atmospheres!) to operate in 1.

Main characteristics of R744 (CO2 carbon dioxide) R744 has a global warming potential (GWP) of 1 and is non-flammable. However, the extremely high operating pressures of R744 and hazards associated with potentially high concentrations of CO2 in vehicle cabins or working environments means this refrigerant must be used with care. The refrigerant used in Memmert ICHeco/ICPeco appliances with the abbreviation R744 and the chemical molecular formula CO2 has a GWP value of 1 and is therefore almost climate-neutral. By contrast, the refrigerant R134a used in many comparable temperature control appliances with a GWP of 1430 after release contributes 1430 times as strongly to El gas R744 es un gas refrigerante a base de CO2, respeta el medioambiente y no afecta a la capa de ozono, con excelentes propiedades termodinámicas. 967254220 info@simagas.es Tienda Online R744 (CO2) is refrigerant grade CO2, used as a replacement for R134a and R404A in ultra-low, low and medium temperature refrigeration applications.
