An arrangement for use in a refrigeration system includes a compressor, a condenser, at least one evaporator unit, and at least one expansion valve. The arrangement includes first and second microsystems and first and second controllers. The first microsystem includes a first MEMs sensor configured to measure at least a first operational parameter of a first of the plurality of refrigeration devices. The first controller is operable to generate a first actuator control signal based on a first control signal, and is configured to generate the first control signal based directly or indirectly on the first operational parameter measurement. The second microsystem includes a second MEMs sensor configured to measure at least a second operational parameter of a second of the plurality of refrigeration devices. The second controller is operable to generate a second actuator control signal based on a second control signal, and is configured to generate the second control signal based directly or indirectly on the second operational parameter measurement.

Distributed microsystems-based control method and apparatus for commercial refrigeration

An arrangement includes a plurality of containers and a processing circuit. Each of the plurality of containers has a microsystem disposed thereon. Each microsystem is configured to sense at least one environmental condition and to sense movement of the corresponding container. The microsystem is configured to communicate information regarding the at least one environmental condition and the movement wirelessly. The processing circuit is operably coupled to receive the information regarding the at least one environmental condition and the movement from each of the microsystems.
