operating pressures that are up to five times higher; 2. the solvent properties of R744 with respect to elastomers and 3. its low “critical temperature” of just 31°C, with the consequence that on hot days R744 can no longer be condensed by Secondary systems: The R744 is used as a secondary fluid and is pumped around the heat exchangers. Partial evaporation can occur because of the volatility of R744, but saturated refrigerant will exit the evaporator (i.e.

The KONFORT 744 implements a range of innovative solutions and differs from the other models in the KONFORT Series for the fact that it is designed and made specifically for use with the latest A/C systems that use R744 (CO2) as refrigerant.

has some additional technical requirements to other conventional refrigerants. 2. R744 (CO 2) AS REFRIGERANT The use of R744 (CO 2) as refrigerant was first suggested in 1850 by the Alexander Twining of Britain.

Due to the environmentally harmful properties of synthetic refrigerants, it has been experiencing a renaissance for several years. Memmert has also committed itself to the use of natural, environmentally friendly refrigerants.

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. The gas cooler rejects heat from the high pressure CO2 to the environment.

Global introduction of R744 necessary To effectively reduce pressures on the atmosphere, an “island solution” with carbon dioxide - limited to Europe or even Germany - is insufficient. We need to act globally.

With an Ozone Depleting Potential (ODP) of 0 and a Global Warming Potential (GWP) of 1, R744 (CO2) is a natural refrigerant. The natural refrigerants that merit extensive re-evaluation and re-introduction are Ammonia (R717), Carbon Dioxide (R744), Hydrocarbons and Water. Ammonia remains in widespread use, and the application thereof to areas such as commercial refrigeration and air conditioning, particularly as alternative to the still widely used R22, is growing. The KONFORT 744 implements a range of innovative solutions and differs from the other models in the KONFORT Series for the fact that it is designed and made specifically for use with the latest A/C systems that use R744 (CO2) as refrigerant.

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.

The refrigerant for busses . Carbon dioxide (R744) is over a thousand times less harmful on the atmosphere than the conventional R134a refrigerant. It has an excellent cooling capacity, it is not flammable and readily available worldwide at low cost. Leading bus manufacturers already launched the first models with R 744 air conditioners.

You can find R-744 being used in vending machines, automobiles, supermarkets, and even in ice-skating rinks. The sheer versatility of R-744 and its climate friendliness is the reason we have seen such growth in its uses. Även om standardspecifikationen för R744 för närvarande är under översyn, är vi medvetna om att fukthalten är kritisk i kylanläggningar.

Además el anhídrido carbónico (CO 2 ), es ampliamente disponible. R744 (CO2) is refrigerant grade CO2, used as a replacement for R134a and R404A in ultra-low, low and medium temperature refrigeration applications. 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.

A-Gas only sources CO2 that is recovered and not produced, so no new CO2 enters the atmosphere, helping you reduce your carbon footprint further. 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 Oils for refrigerant CO 2: Refrigerant pressure depending on the oil temperature and the refrigerant content (mass % of refrigerant in oil-refrigerant blend). Warning values for used oils The listed polyolester oils and the polyalkylene glycol oil are categorized as group KB according to DIN51503, Part 1. R744 is refrigerant grade CO2, a natural alternative with an ultra-low GWP and ultra-low moisture content for various refrigeration applications. The refrigerant for busses . Carbon dioxide (R744) is over a thousand times less harmful on the atmosphere than the conventional R134a refrigerant.
