Why can't the refrigerator be used upside down or sideways?

The general method is to put the refrigerator in the correct place for more than 4 hours, so that the internal pressure is balanced and the lubricating oil flows back and then the machine is turned on.
When the refrigerator is inverted, the refrigerant pressure inside the refrigerator will be unbalanced. Generally, in order to reduce the working noise, the compressor motor is suspended by three suspension springs. If the refrigerator is lifted upside down or tilted excessively during transportation, it will Let the lubricant flow into the refrigeration system above the compressor and the motor.Compressor Refrigerator Ice machine

Humans have known from a very early time that food stored at a lower temperature is not prone to spoilage. In more than 2000 BC, the ancient residents of the Euphrates and Tigris valleys of Western Babylon had begun to pile ice cubes in the pits to refrigerate meat. In the Shang Dynasty (early 17th century BC to 11th century BC), China also knew how to use ice cubes to refrigerate food. In the Middle Ages, many countries also appeared in the original refrigerators that put ice cubes in special water tanks or stone cabinets to preserve food. Until the 1850s, this type of refrigerator was still sold in the United States.
In 1822, the famous British physicist Faraday discovered that gases such as carbon dioxide, ammonia, and chlorine would turn into liquids under pressurized conditions, and they would turn into gases when the pressure was reduced. In the process of changing from liquid to gas, it will absorb a lot of heat, causing the surrounding temperature to drop rapidly. Faraday’s discovery provided a theoretical basis for the invention of artificial refrigeration technologies such as compressors. The first artificial refrigeration compressor was invented by Harrison in 1851. Harrison is the boss of Australia's "Geelong Advertising". When he used ether to clean the typeface, he found that the ether had a strong cooling effect when it was coated on the metal. Ether is a liquid with a very low boiling point, and it is prone to evaporation and heat absorption. Harrison developed a refrigerator that uses ether and a refrigerator pressure pump after research, and applied it to a winery in Victoria, Australia, for cooling and cooling during brewing.
In 1873, German chemist and engineer Karl von Linde invented a refrigerator using ammonia as a refrigerant. Linde uses a small steam engine to drive the compression system, which causes the ammonia to undergo repeated compression and evaporation to produce refrigeration. Linde first applied his invention to the Seedumar brewery in Wiesbaden, designing and manufacturing an industrial refrigerator. Later, he improved industrial refrigerators. To make it miniaturized, in 1879, the world's first artificial refrigeration household refrigerator was manufactured. This steam-powered refrigerator was quickly put into production, and by 1891, 12,000 units had been sold in Germany and the United States.
The first refrigerator that used an electric motor to drive a compressor was invented in 1923 by Swedish engineers Brighton and Mendes. Later, an American company bought their patent and produced the first batch of household refrigerators in 1925. The electric compressor and refrigerating box of the original refrigerator were separated. The latter was usually placed in the home's kiln or storage room, connected to the electric compressor through a pipe, and later merged into one. Before the 1930s, most of the refrigerants used in refrigerators were unsafe, such as ether, ammonia, sulfuric acid, etc., or they were flammable, corrosive, or irritating. Later, I began to search for a safer refrigerant, and finally found Freon. Freon is a non-toxic, non-corrosive and non-flammable fluorine compound. It soon became a refrigerant in various refrigeration equipment and has been used for more than 50 years. However, it was discovered 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.
