Table 1 shows a simple comparison of R744 with other types of refrigerants, including those that are currently commonly used and those that are currently being evaluated for future use. It uses a simple “traffic light” system and employs the common HFCs, such as R404A and R134a as a baseline.

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. 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.

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 is a natural fluid, present in great quantity in the atmosphere In terms of physical characteristics, it should be known that it is heavier than air, odorless and colorless. 1. Criteria for refrigerant selection 4 2. Properties of R744 4 3. An Introduction of transcritical operation 7 4.

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. KONFORT 744 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.

REFRIGERATION IN RETAIL AND SUPERMARKETS

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.
