How does the refrigerator work?
1) Compressed refrigerator: This type of refrigerator provides mechanical energy from an electric motor and works on the refrigeration system through a compressor. The refrigeration system is made using a low-boiling refrigerant that absorbs heat during vaporization. The advantage is that the life is long and the use is convenient. At present, 91 to 95% of the refrigerators in the world belong to this category. At present, the commonly used refrigerator uses a refrigerant called R600a as a hot "porter" to "carry" the "hot" in the refrigerator to the outside of the refrigerator. 2) Absorption refrigerator: This kind of refrigerator can use heat source (such as gas, kerosene, electricity, etc.) as power. The ammonia-water-hydrogen mixed solution is used for the purpose of cooling in the continuous absorption-diffusion process. Its shortcomings are low efficiency, slow cooling, and it has gradually been eliminated. 3) Semiconductor refrigerator: It is a refrigerator that realizes refrigeration by using the principle of generating a Peltier effect on a PN type semiconductor through a direct current. 4) Chemical refrigerator: It is a refrigerator that uses some chemicals to absorb heat when it absorbs heat. 5) Electromagnetic vibrating refrigerator: It is a refrigerator that uses an electromagnetic vibrating machine as the power to drive the compressor. The principle and structure are basically the same as those of the compression type refrigerator. 6) Solar refrigerator: It is a refrigerator that uses solar energy as a cooling energy source. 7) Insulated demagnetization refrigeration refrigerator. 8) Radiation cooling refrigerator. 9) Solid refrigeration refrigerator. 58Pcs Tool Kit,Combination Tools,100Pcs Tool Kit,Multi-Purpose Tool Kit SHAOXING SINO IMPORT & EXPORT CO.,LTD , https://www.sxsmarto.com
