As a result of rapid economic development, cold storage is becoming an important equipment for transport and storage in all sectors. Most people, however, have little knowledge of cold storage. Today, we'll show you all the way to the freezer。
Refrigeration classification
The types of cold banks are quite rich, and they are used in general by volume size (area), cooling temperature (temperature), and cooling use (function)。
Volume size
Based on the size of the freezer, it can be broadly classified as large, medium and small. The volume of more than 10,000 tons is large and the volume of less than 10,000 tons small. The volume formula is an internal volume* volume utilization factor (0. 5 ~0. 6 )* food unit weight, with three values multiplied by cold storage tonnage。
Refrigeration temperature
As the temperature requirements for cold banks vary across sectors, they can be broadly classified as high, medium, low, and ultra-low。
Typically, temperatures at 0 degrees and above are high-temperature cold banks, mainly for eggs, fruit and vegetables, medicines, etc.; temperature at 18 degrees, mainly for low- and medium-temperature cold banks, mainly for meat, aquatic products, etc.; temperature at 20 degrees ~ 30 degrees for low-temperature cold banks; and temperature at less than - 30 degrees for ultra-low-temperature cold banks, mainly for special requirements such as medicines, vaccines, etc。
Refrigeration use
The usual classification of cold banks is the classification of specific uses used for the installation of cold banks, which can be broken down into pharmaceutical colds, meat colds, blood colds, vaccine colds, fruit colds, aquatic colds, etc。
Computation of electricity consumption in cold storage
In the selection process, in addition to the size, volume and cost of the freezer, the amount of electricity consumed in the freezer needs to be considered. So, what are the factors that affect the consumption of electricity in cold storage and how should it be calculated。
Important factors affecting the freezer are the temperature, capacity, external environment, operating time, such as the lower temperature, the greater the power of equipment configurations such as compressors; the greater the capacity of the freezer, the greater the amount of refrigeration required and the greater the amount of electricity consumed
The cooler power formula, 1. 73* average voltage* average power factor * start-up hour/10000 (kw. H), can be simplified as the compressor consumption = the compressor allocated volume* power distribution factor (kw. H), the compressor allocated volume = the compressor average consumption * start-up hour, and the compressor gross consumption/distribution accumulation factor (kw/a)。
Storage
Hangzhou led the construction and decoration of a complex, office improvements, construction works, decoration works, hydroelectric works, heating works, lawn works, steel structural works, etc. That have been in operation for more than a decade, with space design and project construction experience
