Abstract (en)
[origin: EP2196740A2] The method involves determining refrigerant temperatures (T1-T3) in an inlet region of a compressor (14) and outlet regions of a condenser (16) and an expansion valve (18) using temperature sensors (28, 30, 32) arranged in a closed loop (10), respectively. Enthalpies of the closed loop are calculated from the determined temperatures. Heat energy and electrical energy of cooling machine are calculated from difference of calculated enthalpies. A coefficient of performance of the cooling machine is determined from quotient of the calculated heating and electrical energies. An independent claim is also included for a cooling machine comprising an evaluation device.
