Suitable temperatures for food cold storage and fresh food cold storage
We often encounter this situation, the fruit is broken, the pulp has changed, and a series of other situations, so why does this happen? Because different fruits are suitable for preservation at different temperatures, when buying a fruit preservation cabinet we should also understand the preservation temperatures of these fruits in order to correctly set the appropriate temperature for food cold storage and fresh food cold storage.

How is the price of cold storage calculated?
The power of the compressor determines its power consumption; at the same time, since different compressors have different models and specifications, choosing different models of compressors will also affect the price. (Note) Currently, there are three main types of air conditioning compressors commonly used on the market - screw type, scroll type and centrifugal type. Among them, screw units are widely used in small air conditioning systems due to their low noise and stable and reliable operation.
