A cloud-based system that includes a plurality of remote refrigerated appliances equipped with a communication and temperature control board with sensors interface, a computing cloud, and a distributed software environment for refrigerators operational data acquisition and storage and for developing testing and executing temperature control methods and with energy optimization techniques is provided. The communication and temperature control board activates the elements of a refrigerated appliance based on direct control of the remote distributed environment executing the temperature control method in software. The distributed software environment executing the temperature control method acquires operational data and energy consumption from the sensors connected to the remote communication and temperature control board and employs energy optimization techniques.
