What is the difference between air-cooled and direct-cooled refrigerators

1, refrigeration structure: air-cooled refrigerator structure is more complex; direct cooling refrigerator structure is simple.

2, refrigeration volume: air-cooled effective refrigeration volume of more than 300 liters; direct cooling effective refrigeration volume of less than 300 liters.

3, refrigeration equalization: air-cooled refrigerator is fan air supply; direct cooling refrigerator due to power cooling.

4, cooling speed: air-cooled refrigerator is cold air forced circulation; direct cooling refrigerator due to rely on natural convection.
