How The Refrigerator Works

1. Compression refrigerator: This type of refrigerator is provided with mechanical energy by the motor, and the compressor performs work on the refrigeration system. The refrigeration system is made by the principle of absorbing heat when evaporating and vaporizing refrigerant with a low boiling point. Its advantages are long life and easy to use. 91-95% of refrigerators in the world belong to this category. Commonly used refrigerators use a refrigerant called R600 refrigerator a as a heat "porter" to "carry" the "heat" in the refrigerator to the outside of the refrigerator.

2. Absorption refrigerator: This type of refrigerator can use heat sources (such as gas, kerosene, electricity, etc.) as power. The ammonia-water-hydrogen mixed solution is used to achieve the purpose of refrigeration in the continuous absorption-diffusion process. Its disadvantages are low efficiency and slow cooling, which has been gradually eliminated.

3. Refrigerator: It is a refrigerator that uses the principle of generating Peltier effect on the node by applying direct current to PN-type semiconductors to achieve cooling.

4. Chemical refrigerator: It is a refrigerator that uses certain chemical substances to strongly absorb heat when dissolved in water to obtain a cooling effect.

5. Electromagnetic vibrating refrigerator: It is a refrigerator that uses an electromagnetic vibrating machine as the original power to drive the compressor. Its principle and structure are basically the same as those of a compression refrigerator.

6. Solar refrigerator: It is a refrigerator that uses solar energy as a cooling energy source.

7. Adiabatic demagnetization refrigeration refrigerator.

8. Radiant refrigeration refrigerator.

9. Solid refrigeration refrigerator.
