The computer-controlled freezer only needs to click on the right temperature with your fingertips according to your needs, but the price is obviously more expensive.
Is it better for the supermarket freezer to be cold or cold?
The biggest difference between air cooling and direct cooling is the problem of frost formation. Air cooling does not need to worry about frost formation in the commercial freezer and is convenient to use, but the freezing speed in the commercial freezer is slower than that in the direct cooling freezer and consumes a lot of electricity, the price is higher.
The direct cooling freezer has simple structure, low price, fast freezing and cooling speed, low power consumption and low noise, but the cooling in the refrigerating chamber is slow, the temperature in the freezer is uneven, the evaporator in the freezing chamber is easy to frost and defrosting is troublesome.
