Measurement value e.g. evaporator pressure value, compensating method for controlling heat pump in compression refrigerating system, involves adding result of multiplication to currently stored measurement value to obtain corrected value

摘要

The method involves detecting a physical measurement variable by a sensor, and outputting measurement values (MW) such as evaporator output temperature value or evaporator pressure value, as sensor signals. The values are stored in a memory and are evaluated by forming average values. Gradients of a process of the sensor signals are determined by forming a difference of two of the values or of two average values and by multiplication of the difference with a correction factor. The multiplication result is added to the currently stored measurement value to obtain a corrected measurement value. An independent claim is also included for a compression refrigerating system comprising an evaporator and a regulator.
