Embodiment Construction
[0056] figure 2 It is a schematic diagram of the liquid return distributor of the present invention, as figure 2 As shown, the liquid return distributor of the present invention is used to distribute cold storage liquid back to the multi-temperature zone cold storage system. The cold storage system may include a refrigeration unit 100, a first cold storage tank 110, a second cold storage tank 120, and a third cold storage tank. The tank 130 and the fourth cold storage tank 140 , the quick-freezer 150 , the freezer 160 , the refrigerator 170 , the fresh-keeping store 180 , the office area 190 , the cooling distributor 300 , and the liquid return distributor 400 . The liquid return distributor receives the liquid return of cold storage liquid from the quick-freezer 150, freezer 160, cold storage 170, fresh-keeping store 180 and office area 190 of the multi-temperature zone cold storage system, and returns the received cold storage liquid to the The first cold storage tank 110...

The invention provides a liquid return distributor. The liquid return distributor utilizes the first cold storage liquid return line, the second cold storage liquid return line, the third cold storage liquid return line and the fourth cold storage liquid return line. The pipeline distributes the cold storage liquid return liquid of the multi-temperature zone cold storage system, and the liquid return distributor receives the cold storage liquid return liquid of the quick-freezer, freezer, cold storage and fresh-keeping store of the multi-temperature zone cold storage system, and the received The cold storage liquid returns 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 distributor of the present invention can flexibly carry out the mode conversion of each system, according to different seasons According to the needs of storage temperature in different temperature zones, the mode can be changed flexibly, which can be changed to ultra-low temperature storage or high-temperature storage without increasing 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 the application of the return liquid distributor in the multi-temperature zone cooling system.
Description
technical field [0001] The invention relates to a liquid return distributor, in particular to a liquid return distributor applied 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 independent...
