What are the parts of a refrigerator?
1. compressorCompressors for household refrigerators are generally closed compressors. Its full name is "fully enclosed type motor compressor for refrigerators". It actually seals the compressor and motor in the housing
3. heat insulation layerIn the past, the thermal insulation layer of the refrigerator was filled with glass wool, and now the refrigerator insulation layer is made of polyurethane foam plastics. The polyurethane foam plastics are foamed by adding foaming agent in the polymerization process of isocyanate and polyetherFoaming agents used to use R11. This foaming agent has a great destructive effect on the ozone layer in the atmosphere. Now the foaming agents are gradually changed to R141b or cyclopentane. These two kinds of foaming agents are environmentally friendly foaming agents
The shell and door shell are generally made of cold rolled steel sheet of 0.4-0.8mm. The surface is treated by phosphating and spray (or spray painting). In order to be beautiful, the door shell is full of color plates, and some refrigerators have used wire drawing board2. boxes of bravery, door gall, usually with thick 1.2-5mm ABS plate or HIPS plate, made by vacuum molding. The box is also made of aluminum plate, this kind of box strength is better than plastic, but the corrosion resistance is inferior to plastic
The refrigerator is mainly composed of five parts: the box body, the door, the refrigeration system, the electrical system and the accessoriesI. box and door bodyThe box body and the door body are composed of a plurality of chambers according to different temperature requirements, and are isolated from the outside air and are kept at a certain low temperature respectively. The box body and the door body are composed of a box case, a box case, a door shell, a door gall, etc., and an insulating material
