The invention discloses a liquid return distribution method of a liquid return distributor. The liquid return distribution method utilizes the first cold storage liquid return line, the second cold storage liquid return line, and the third cold storage liquid return line of the liquid return distributor. The liquid return pipeline and the fourth cold storage liquid return pipeline distribute the cold storage liquid return liquid of the multi-temperature zone cold storage system, and receive the cold storage of the quick-freezer, freezer, cold storage and fresh-keeping store of the multi-temperature zone cold storage system liquid return, and return the received cold storage liquid back to the first cold storage tank, the second cold storage tank, the third cold storage tank and the fourth cold storage tank; the cold storage system adopting the liquid return distribution method of the liquid return distributor of the present invention can Flexible mode conversion of each system, according to the needs of storage temperature in different temperature zones in different seasons, flexible mode conversion, can be changed into ultra-low temperature storage or high-temperature storage, and does not increase investment. At the same time, the refrigeration unit does not need to be started frequently, and the energy consumption of the system is low. The invention also discloses a refrigeration method of the multi-temperature zone cold storage system.
Description
technical field [0001] The invention relates to a liquid return distribution method of a liquid return distributor and a refrigeration method of 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 cooling mode of the cold storage system in the prior art, such as Figure 1A As shown, the ultra-low temperature / quick freezer ...
