现代家用新鲜食品的电冰箱或冻结箱主要有三个部份:1.箱体。2.机械装置、(压缩冷凝机组及蒸发器)。3.电气线路。箱体内装有并承托蒸发器和压缩冷凝机组;它也提供搁架和食品或饮料的贮藏地位。液体制冷剂在蒸发器内膨胀而成为蒸气,这蒸气吸收箱体中食物或饮料的热量。压缩冷凝机组排除蒸发器所吸收的热量,然后液体制冷剂回到蒸发器中重复制冷循环。这里叙述的基本的新鲜食品的电冰箱可能有许多品种变化及附件。(附件是些并非必要,然而可提供某些方便的零件)。冻结食品的冻结箱可能
Modern household fresh food refrigerator or frozen box has three main parts: 1. Box. 2. Mechanical installation, (condensing unit and evaporator). 3. Electrical wiring. The cabinet contains and supports the evaporator and the condensing unit; it also provides shelving and food or beverage storage. The liquid refrigerant expands in the evaporator into vapor, which absorbs the heat of the food or beverage in the tank. Compressed condensing unit to exclude the heat absorbed by the evaporator, and then liquid refrigerant back to the evaporator to repeat the refrigeration cycle. The basic fresh food refrigerators described here may have many variations and accessories. (Accessories are not necessary, however, some handy parts are available.) Frozen food freezing box possible
