Is there radiation in the refrigerator? Is it okay to put it in the bedroom?

The refrigerator can be placed in the bedroom, but it is ok, that is, it is loud when it starts and stops, and there is noise when it runs, especially at night, which will affect the rest. It is recommended not to put it in the bedroom. The electromagnetic radiation of refrigerator is very small, and the harm to human body is very small, which can be ignored.

Refrigerator is a kind of refrigeration equipment to keep a constant low temperature, and it is also a civilian product to keep food or other items at a constant low temperature. There are compressors, ice makers, cabinets or boxes for refrigeration, and there are storage boxes with refrigeration devices in the boxes.

The volume of domestic refrigerators is usually 20 ~ 500 liters. 19 10 the world's first compressed refrigeration household refrigerator came out in the United States. 1925 Lido Company of Sweden has developed a household absorption refrigerator. 1927 the general electric company of the United States has developed a fully enclosed refrigerator. 1930, air-cooled continuous diffusion absorption refrigerators with different heating methods were put on the market. 193 1 year, a new refrigerant freon 12 was successfully developed. Domestic thermoelectric refrigerators began to be produced in the second half of 1950s, and refrigerators began to be produced in China in 1950s.

The first refrigerator with motor-driven compressor was invented by Swedish engineers Brighton and Mendes in 1923. Later, an American company bought their patent and produced the first batch of household refrigerators at 1925. In the first refrigerator, the electric compressor and the refrigerator were separated, and the latter was usually placed in the cellar or storage room of the family and connected with the electric compressor through pipes, and then they were combined into one. Before 1930s, most refrigerants used in refrigerators were unsafe, such as diethyl ether, ammonia water and sulfuric acid. Flammable, corrosive or irritating. Later, I started looking for a safer refrigerant and found Freon. Freon is a non-toxic, non-corrosive, non-flammable fluorine compound, which quickly became the refrigerant of various refrigeration equipment and has been used for more than 50 years. However, it has been found that freon has a destructive effect on the ozone layer of the earth's atmosphere. So people began to look for new and better refrigerants.
