Embodiment Construction
[0063]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.

The invention discloses a multi-temperature zone refrigeration storehouse system. The multi-temperature zone refrigeration storehouse system comprises a refrigeration unit, a first cold accumulation cylinder, a second cold accumulation cylinder, a third cold accumulation cylinder, a fourth cold accumulation cylinder, a quick-freezing storehouse, a freezing storehouse, a refrigeration storehouse and a fresh-keeping storehouse; cold accumulation liquid is provided for the first cold accumulation cylinder by the refrigeration unit; the first cold accumulation cylinder is connected to the quick-freezing storehouse through a first cold accumulation pipeline; the second cold accumulation cylinder is connected to the freezing storehouse through a second cold accumulation pipeline; the third coldaccumulation cylinder is connected to the refrigeration storehouse through a third cold accumulation pipeline; the fourth cold accumulation cylinder is connected to the fresh-keeping storehouse through a fourth cold accumulation pipeline; besides, the quick-freezing storehouse is connected to the second cold accumulation cylinder through a first returning liquid pipeline; the freezing storehouse is connected to the third cold accumulation cylinder through a second returning liquid pipeline; the refrigeration storehouse is connected to the fourth cold accumulation cylinder through a third returning liquid pipeline; and the fresh-keeping storehouse is connected to the first cold accumulation cylinder through a fourth returning liquid pipeline. By adopting the multi-temperature zone refrigeration storehouse system, switching of various system modes can be flexibly performed, and transformation among various refrigeration storehouse temperature zone modes is 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...
