Introduction to Basic Types of Cold Storage

For compressors with differences in different evaporation system equipment, when making a selection, it should start from the backup and matching of other equipment in the refrigeration system, and comprehensively consider the stable and effective operating conditions of the entire refrigeration system.
The total refrigeration capacity of the compressor should also take the actual total production volume and economic conditions as the selection criteria. In most cases, the total number of compressors should be at least two.
When selecting a compressor, it is necessary to consider whether the refrigeration capacity of the entire cold storage can meet the highest requirements during the peak season.
When calculating the data, the operating conditions of the compressor must be reasonably planned by strictly referring to the temperature of the highest - temperature water.
For the same cold storage, the models and series of compressors should be kept consistent as much as possible, which is convenient for later management and replacement of parts.

Basic types of cold storage:
(1) High - temperature cold storage (fresh - keeping cold storage): The temperature is generally (5℃ - -5℃), suitable for storing (vegetables, fruits, dried foods).
(2) Medium - temperature cold storage (refrigerated cold storage): The temperature is generally (-10℃ - -20℃), suitable for storing (meat products, poultry, fish and shrimp).
(3) Low - temperature cold storage (quick - freezing cold storage): The temperature is generally (-20℃ - -45℃), suitable for storing (dumplings, etc., short - term quick - frozen products).
(4) Ultra - low - temperature cold storage (freezing cold storage): The temperature is generally (-30℃ - -80℃), suitable for storing (tuna, special expensive items such as chemical substances).
(5) Medical cold storage (medicine cold storage): The temperature is generally (2℃ - 8℃), suitable for storing (medicines, vaccines, pharmaceuticals, etc.).
