TEMPERATURE CONTROL IN DOMESTIC REFRIGERATORS AND FREEZERS

摘要

Temperature control of food in the home is vitally important. In the past decade there have been 15rnpublished surveys of temperatures in domestic refrigerators. The last detailed survey carried out in the UKrnwas in 1991. Refrigerators are now fitted with lower power compressors and thicker insulation to enablernthem to achieve low energy consumption. Therefore there is a possibility that due to these changes,rntemperatures in domestic refrigerators have changed. This paper reports results from a survey of currentlyrnused domestic refrigerators and compares the results to those obtained in 1991.rnIn addition the paper examines temperatures in domestic freezers. Although freezers pose less of a foodrnsafety risk they do contribute to poor food quality and potential waste if the food is not maintained at lowrnenough conditions. None of the surveys published to date examines temperatures in domestic freezers.
