  • Method and device for diagnosis of the refrigerant quantity in an air conditioning system
    Patent number: 5647222
    Abstract: A method for diagnosis of the refrigerant quantity in an air conditioning system in which an evaporator (10) followed by a liquid-separating accumulator (11), a compressor (12), a condensor (13), and a shut-off device (14) are connected in series after one another in a closed circuit for circulation of a refrigerant. The pressure of the refrigerant is measured between the condensor (13) and the shut-off device (14). The temperature of the refrigerant is measured after the compressor (12) and also before the evaporator (10). The measured values are compared with stored set values, for determining whether the refrigerant quantity is within, or outside, a reference interval.
