Abstract

Method for using a sensor (11) and a receiver (12) for monitoring a refrigeration system which has a compressor (1) and a pipe (8) which comes from the compressor and which conveys refrigerant. According to the invention, a temperature detector (13) of the sensor is disposed on top of the pipe in order to indirectly measure the temperature of the refrigerant, and a processor (17) of the sensor is used to calculate an operating state value, a cycle time and a load factor for the compressor based on the measured temperature, after which the sensor sends these values to the receiver.
