家用电器是量大面广的家庭耗能器具,因此,开发低能耗的家用电器历来受到世界各国的重视。近几年来,一些国家通过采用新技术、新材料、新工艺,相继推出各种节能型家用电器,受到广大消费者的欢迎和好评。一、国外低能耗家用电器研制概况电冰箱和冷冻箱是耗能较多的家用电器,在日本,1988年电冰箱耗电约占家庭用电的25%,因此,开发低能耗电冰箱、冷冻箱为各国所瞩目,电冰箱的主要节能技术措施有:1、制冷压缩机的节能八十年代前,国外电冰箱使用的压缩机均为往复压缩机。八十年代初,以日本三菱公司为首的一些公司研制成功旋转压
Household appliances are widely used home energy-consuming appliances. Therefore, the development of low-energy appliances has always been valued by countries around the world. In recent years, some countries have adopted various new technologies, new materials, and new technologies to launch various kinds of energy-saving home appliances in succession, which have been welcomed and praised by consumers. I. Overview of the development of low-energy household appliances in foreign countries Fridges and freezers are household appliances that consume more energy. In Japan, in 1988, refrigerators consumed about 25% of household electricity. Therefore, low-energy refrigerators and freezers are being developed. The box has attracted worldwide attention. The main energy-saving technical measures for refrigerators include: 1. Energy saving of refrigeration compressors Before the eighties, the compressors used in foreign refrigerators were reciprocating compressors. In the early 1980s, companies led by Mitsubishi Corp. in Japan successfully developed rotary pressure.
