Advantages of semiconductor refrigerators？

1. No mechanical transmission components, no wear, no noise, long service life

2. No need for refrigerant refrigeration (both compression and absorption types are required), absolutely environmentally friendly

3. High efficiency and low power consumption (below 100W, the power consumption is only half of that of compression and absorption)

4. Due to the use of refrigeration chips, semiconductor refrigerators can be of any size, and even USB refrigerators powered by USB interfaces have emerged.
