Abstract (en)
[origin: EP1806548A1] The air conditioning system has a coolant circuit carrying a supercritical fluid and containing a compressor (14) with a control valve, a gas cooler (11), an expander (12) and an evaporator (13). It differs by incorporating a regulating module (40) that controls the compressor valve command signal during the system's starting phase so that the compressor's output pressure is maintained below the cut-off level. The regulating module calculates a current value for the command signal and compares it with a threshold value when the compressor is at minimal power.
