Classification: CPC B  F | IPC B

Claim 13:
14. A leak detection module comprising:
a group of sensors configured to measure physical characteristics of a refrigerant contained in a cooling circuit of an air-conditioning circuit, the sensors in the group configured to measure the physical characteristics of the refrigerant in different parts of the cooling circuit corresponding to different enthalpy levels;
a voltage sensor configured to measure a power supply voltage of a compressor of the air-conditioning system; and
a controller configured to:
determine a mass flow rate of the refrigerant based in part on the power supply voltage of the compressor as measured by the voltage sensor;
determine a total quantity of the refrigerant contained in the cooling circuit based on at least: (i) the mass flow rate, (ii) data corresponding to geometric and technical parameters of different components of the air-conditioning system, (iii) a type of the refrigerant, and (iv) signals generated by the group of sensors, the signals representative of the physical characteristics of the refrigerant in the different parts of the cooling circuit.
