Summary

This works explores the use of heat flux transducers to evaluate the thermal performance of household refrigerators. Such devices were placed on the external surfaces of the refrigerator and also on the evaporator and used during reverse heat loss and pull down standard tests. One of the potentialities of this work is the determination of the heat transfer rates through each one of the external walls of the refrigerator, enabling the identification of the critical heat transfer paths from the surrounding to the interior of the cabinet. Another potentiality is the determination of the instantaneous total heat transfer rate to the interior of the cabinet, refrigeration capacity and system coefficient of performance, which is a unique characteristic of this work.
