1. An arrangement for use in a refrigeration system, the refrigeration system comprising a plurality of refrigeration devices including a compressor, a condenser, at least one evaporator unit, and at least one expansion valve, the arrangement comprising:

  • a first microsystem including a first MEMs sensor configured to measure at least a first operational parameter of a first of the plurality of refrigeration devices;

    a first controller configured to generate a first actuator control signal based at least in part directly or indirectly on the first operational parameter measurement;

    a second microsystem including a second MEMs sensor configured to measure at least a second operational parameter of a second of the plurality of refrigeration devices; and

    a second controller configured to generate a second actuator control signal based at least in part directly or indirectly on the second operational parameter measurement.
