Abstract

Food transport and storage at low temperatures has always been an important matter worldwide and is becoming even more important due to dietary needs and population growth. The issue of improving food storage applies to food transportation in refrigerated vans and food storage in domestic refrigerators and freezers. In this paper, heat loads are introduced into a freezer and vegetable zone through short door openings (five door openings lasting 1 min each and spaced at 30 min intervals) and single 3 min door opening with and without phase change materials (PCMs) with static conditions (no fan to circulate cold air) and with dynamic condition (with fan to circulate cold air) ambient air through the walls. Also the performance of PCM inside the refrigerator (freezer and vegetable zone) with varying the mass with surface area in both static and dynamic conditions was investigated. The temperature responses of the freezer with and without PCM are examined, with regards to heat loads introduced through door openings and power loss. Energy consumption of the refrigerator with and without PCM is also investigated.Keywords: Food transport, phase change material, refrigerator performance
