How to calculate the selection of refrigeration unit?

No matter what season, in fact, refrigeration units have been used, the purpose is to be able to extend the shelf life of products. According to the refrigeration needs of different areas of cold storage, the specifications of refrigeration units selected by manufacturers are also different. The following is a simple selection calculation method.

No matter what brand of compressor unit is selected, it is determined according to the evaporation temperature of active cold storage and the effective working volume of cold storage. In addition, it also refers to the condensing temperature of frozen or refrigerated items, the amount of storage, the frequency of goods entering and leaving the storage and other parameters.

Usually, the formula for calculating the refrigerating capacity of high temperature cold storage is:

Cold storage volume ×90×1.16+ positive deviation, positive deviation is determined according to the condensing temperature of frozen or refrigerated items, storage volume, cargo in and out of storage frequency, the range is between 100-400W;

The formula for calculating the refrigerating capacity of medium temperature cold storage is:

Cold storage volume ×95×1.16+ positive deviation, positive deviation range between 200-600W;

The formula for calculating the refrigerating capacity of the compressor unit of low temperature cold storage is:

Cold storage volume ×110×1.2+ positive deviation, positive deviation range in 300-800W.

The use of semi-closed refrigeration compressor is also very wide, the types of units are also many, the right type of units, in the early stage can reduce capital investment, and in the use of later, can also reduce more energy consumption.
