Freezer features 2

The refrigeration load of the refrigeration room of the freezer is the heat that must be taken out of the refrigeration room per unit time; or the amount of cold that the refrigeration room obtains from the refrigerator in the unit time.

The purpose of calculating the refrigeration load of the refrigeration room is to correctly and reasonably determine the cooling equipment load and mechanical load of each cold room. The cooling load of the cold room is not constant throughout the year, and its load size is affected by many aspects.

For example, the changes in the external environment temperature, the amount of food storage in the cold room, the difference in the amount of cold processing of food in the off-season and peak seasons, and many factors in the operation and management methods. Usually, the calculation of the cooling load is one of the first tasks in the design of the cold storage refrigeration device. One. Therefore, it is very important for the refrigeration design to reasonably determine the refrigeration load of the cold room.

The most unfavorable working conditions should be considered when calculating the cooling load of the refrigerator. This is the principle of outdoor calculation. For rooms that transfer heat from indoor to outdoor, the outdoor temperature in the hot season should be considered; while for rooms that transfer heat from outdoor to indoor, the outdoor temperature in cold season should be considered. The cold rooms of cold storage are mostly of the type that transfers heat from indoor to outdoor.
