Embodiment Construction
[0101] The multi-temperature zone cold storage system proposed by the present invention is different from the traditional cold storage refrigeration method. It adopts a single-machine multi-storey multi-temperature zone mode, and all temperature zones can be changed to the desired temperature zone mode according to needs, that is, freezing Each temperature zone can be converted to each other, and the system can be all freezer, or all cold storage, or all fresh storage, or part of the freezer, part of the cold storage, part of the fresh storage, etc.; all modes can be Make any conversion at any time. If there is an office system, it can provide cooling and heating modes for the office environment, which greatly improves the availability of the system. At the same time, the multi-temperature zone cooling system of the present invention can realize multi-pipeline cooling distribution of cold storage liquid and multi-pipeline return of liquid return through the cooling distributor...

The invention discloses a multi-temperature zone cold storage system comprising: a refrigerating unit, a first cold storage tank, a second cold storage tank, a third cold storage tank and a fourth cold storage tank, a quick freezer, a freezer, a cold storage, a fresh storage, a supply Cold distributor and liquid return distributor; among them, the refrigeration unit provides cold storage liquid for the first cold storage tank, and the first cold storage tank, the second cold storage tank, the third cold storage tank and the fourth cold storage tank provide the cold storage liquid to the cold supply distributor , the cold storage liquid is distributed to the quick-freezer, freezer, cold storage and fresh-keeping warehouse by the cooling distributor; The cold storage liquid is returned to the first cold storage tank, the second cold storage tank, the third cold storage tank and the fourth cold storage tank. By adopting the present invention, the mode conversion of each system and the mode conversion of each cold storage temperature zone can be flexibly performed.
Description
technical field [0001] The invention relates to a cold storage system, in particular to a multi-temperature zone cold storage system. Background technique [0002] The traditional cold storage refrigeration method is that each cold storage corresponds to one or more refrigeration units, and each cold storage corresponds to a refrigeration mode or refrigeration temperature, and the temperature range is a fixed mode, which cannot be changed to other temperature zones or used for other purposes. . When seasonal changes require other temperature zones, there is no other way but to rebuild. Moreover, the entire refrigeration pipeline is a high-pressure pipeline, which requires a large amount of investment and is difficult to maintain later. Figure 1A to Figure 1E It is a schematic diagram of a cold storage system in the prior art, such as Figure 1A As shown, the ultra-low temperature / quick freezer 502 at -65 to -45°C is independently controlled by a refrigeration unit 500, an...
