Abstract
Wine coolers need to guarantee a highly-controlled environment in terms of temperature and humidity for wine storage. According to the International Standard, wine coolers must keep the temperature and the relative humidity of the refrigerated compartments, respectively, in the ranges of 5 to 20 °C and 50% to 80%. Since the temperature difference between the ambient and the cooled cabinet is not so high, the cabinet can operate with a magnetic cooling system. In this work, a transient heat transfer analysis of the cabinet components has been developed. The time required to cool down the wine bottles to a prescribed temperature for different operation conditions of the magnetic cooling system and for varied sizes of the cold heat exchanger have been calculated. The results indicate that the operating conditions of the magnetic refrigeration system and the overall thermal conductance of the cold heat exchanger have a significant impact on the time required to cool down the wine bottles. This should be considered in the design of a wine cooler operating with a magnetic refrigeration system.
