Control of household refrigerators. 2. Alternate control approaches for improving temperature performance and reducing energy use.

Author(s) : GRAVISS K. J., COLLINS R. L.

Type of article: Article

Summary

Three alternative approaches to the conventional control of a top-mount refrigerator are presented: variable temperature bandwidths, uncoupled compressor and evaporator fan, and the combination of these two. These allowed the plant to achieve near-ideal control with respect to improved temperature performance in each compartment. Automatic airflow dampers were used with the dual controllers to independently regulate refrigerator compartment temperature. Plant performance was simulated using a model that computes the refrigerant and airflow systems behaviour.
