Method For Controlling The Operation Of An Air-Conditioning Loop In A Vehicle
First Claim
1. A method for controlling the outlet temperature (TRCPO) of a compressor (CP) built into an air-conditioning loop of a vehicle in which flows a subcritical refrigerant fluid and comprising at least a condenser (CD), an expansion valve (EXV), and an evaporator (EV), the control method comprising:
- a step of calculating a limit temperature at the inlet of the compressor (TRCPI_L),step of estimating a temperature at the inlet of the compressor (TRCPI_E), anda step of modifying a control signal of the compressor (PWMCP) or a setpoint value of the evaporation temperature (SP_TEV).

Abstract
The present invention relates to a method for controlling the outlet temperature (TRCPO) of a compressor (CP) built into the air-conditioning loop of a vehicle in which a subcritical refrigerant fluid flows and including a condenser (CD), an expansion valve (EXV), and an evaporator (EV). The monitoring method comprises the steps of calculating a limit temperature at the compressor inlet (TRCPI_L), estimating a temperature at the compressor inlet (TRCPI_E), and modifying a control signal of the compressor (PWMCP) or a setpoint value of the evaporation temperature (SP_TEV).
