Abstract (en)
[origin: EP4006454A1] Refrigerant loss. A method of detecting a loss of refrigerant from a refrigerant circuit (1) comprising a compressor (5) and an evaporator (4) having an outlet port and an expansion valve (3) having an inlet port and an outlet port, the refrigerant circuit (1) comprising a first sensor (7) for recording a thermodynamic state of the refrigerant at the inlet port of the expansion valve (3) and a third sensor (8) for recording a thermodynamic state of the refrigerant at the outlet port of the expansion valve (3), and a second sensor (9) for recording a thermodynamic state of the refrigerant at the outlet port of the at least one evaporator (4), the method comprising the steps of: recording a first signal indicative of a thermodynamic state of the refrigerant; recording a fourth signal indicative of a thermodynamic state of the refrigerant.
