Embodiment Construction
[0092] The invention proposes a refrigeration method for a multi-temperature zone cold storage system, which is different from the traditional cold storage refrigeration method. The zones can be changed to the required temperature zone mode according to the needs, that is, the temperature zones such as freezing, refrigerating, and fresh-keeping can be converted to each other. One part is cold storage, one part is fresh storage, etc.; all modes can be converted 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 refrigeration method of the multi-temperature zone cooling system of the present invention can realize multi-line cooling distribution of cold storage liquid and multi-line backflow of liquid return through the cooling distributor and the liquid return distributor.

The invention proposes a refrigeration method for a multi-temperature zone cold storage system, which uses a refrigeration unit to refrigerate quick-freezing storage, freezer storage, cold storage and fresh storage; the refrigeration unit is the first cold storage tank. Provide cold storage liquid; supply the cold storage liquid to the cooling distributor through the first cold storage tank, the second cold storage tank, the third cold storage tank and the fourth cold storage tank, and distribute the cold storage liquid to the quick freezer and freezer through the cold supply distributor , refrigerators and fresh-keeping warehouses; the cold storage liquid is returned to the liquid return distributor through the quick-freezer, freezer, cold storage and fresh-keeping warehouse, and 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 refrigeration method for a cold storage system, in particular to a refrigeration method for 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 the refrigeration method of the cold storage system in the prior art, such as Figure 1A As shown, the ultra-low temperature / quick fre...
