What is the difference between direct cooling and air cooling for beverage display cabinets?

Air-cooled beverage display cabinets have more advantages compared to direct cooling display cabinets.

Refrigeration speed and temperature control: air-cooled display cabinets refrigeration faster, more precise temperature control. This is due to the air-cooled technology through the continuous circulation of cold air refrigeration, so that the temperature distribution is more uniform, avoiding the possible existence of direct cooling technology in the refrigeration dead zone problem. 
Defrost and convenience: air-cooled display cabinets do not need to manually stop defrosting often, reducing the maintenance trouble. Direct-cooled display cabinets, on the other hand, are prone to frosting and need to be defrosted manually on a regular basis, which may be inconvenient in a commercial environment. 
Humidity and food sticking problem: air-cooled display cabinets will not be like direct-cooled display cabinets, the interior is always wet, the food will not stick to each other, thus keeping the interior of the display cabinets clean and dry.
Display effect: for convenience stores and other places that need to display goods, air-cooled display cabinets are usually equipped with a glass door, the display effect is better, more attractive to consumers' attention.
In summary, although the air-cooled display cabinets may be slightly higher than the direct cooling display cabinets in power consumption and price, but its refrigeration speed, temperature control, defrosting convenience, humidity control and display effect has obvious advantages, more suitable for commercial environments, especially convenience stores and other places that require efficient refrigeration and good display effect.
