MAHLE R744 air conditioning circuit

MAHLE presents a world first with its R744 air conditioning system, which went into series production with a premium manufacturer in 2016. R744, an entirely natural and environmentally friendly refrigerant, places particular demands on the technology because of its specific characteristics. The thermodynamic properties of R744 differ fundamentally, however, from the chemical alternatives used until now. The first difference is in the pressure levels in the air conditioning system. To work efficiently, pressures from 60 to 130 bar are needed on the high-pressure side of the refrigerant circuit, i.e., downstream of the compressor. This corresponds to six times the pressure of the refrigerant used previously. On the low-pressure side, the occurring pressures are as much as 10 times higher, at 35 to 50 bar. The second major difference is that the refrigerant pressure exceeds the critical point at external temperatures above approximately 25 degrees Celsius. Beyond this point, a gas can no longer liquefy as a result of cooling. This means that under these conditions, R744 will cool continuously via the air thanks to the gas cooler installed in the front end. The high pressures in the system, in particular, have led to the necessary modifications and ultimately the complete redevelopment of the refrigerant circuit for R744.
