PCT No. PCT/SE93/00848 Sec. 371 Date Apr. 13, 1995 Sec. 102(e) Date Apr. 13, 1995 PCT Filed Oct. 18, 1993 PCT Pub. No. WO94/08809 PCT Pub. Date Apr. 28, 1994A 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. |
