Adaptive temperature control of a household refrigerator

Temperature control in household refrigerators and freezers is typically operated through simple on-off actuation devices, which limit the obtainable control performance and flexibility and determine a nonlinear behavior of the system. This manuscript describes an adaptive scheme that improves the characteristics of the induced temperature oscillations, without requiring modifications of the actuation hardware. The adaptive control scheme is then tested on a benchmark simulation model of a commercial refrigerator.

Adaptive Temperature Control in a Freezer with On-Off Actuation

This manuscript describes an adaptive scheme for temperature control in household freezers. Peculiar of the proposed control scheme is the use of standard sensing and actuation equipment, with particular reference to the on-off compressor. After illustrating the rationale of the proposed control, some tests on a detailed simulation model are reported, to validate the approach and show its effectiveness with respect to both food preservation and energy consumption.
