Description
Technical field
The present invention relates to the cold-storage liquid distribution methods of cooling supply distributor more particularly to a kind of for multi-temperature zone refrigeration storage system
The cold-storage liquid distribution method of cooling supply distributor,.
Background technique
Traditional freezer refrigerating mode is that each freezer corresponds to one or more refrigeration unit, also, each freezer is corresponding
One refrigeration mode or cryogenic temperature, temperature range are fixed mode, can not be changed to other warm areas, can not be changed to other
Purposes.When seasonal variations need other warm area libraries, in addition to more building, without other methods.Also, entire refrigeration pipeline is high-voltage tube
Road, investment amount is big, and later maintenance is difficult.Figure 1A to Fig. 1 E is the process schematic representation of the refrigeration storage system refrigerating method of the prior art,
As shown in Figure 1A, -65~-45 DEG C of ultralow temperature/quick freezing repositories 502 are individually controlled by a refrigeration unit 500, and refrigeration unit 500 is logical
It crosses refrigerated heat exchanger 501 and -65~-45 DEG C ultralow temperature/quick freezing repository 502 to exchange heat, whole region is bearing area.Such as Figure 1B institute
Show, -25~-18 DEG C of freezers 503 are individually controlled by a refrigeration unit 500, and refrigeration unit 500 passes through refrigerated heat exchanger 501
It exchanges heat with -25~-18 DEG C of freezers 503, whole region is bearing area.As shown in Figure 1 C, 0~10 DEG C cold fresh-keeping 504 individually
It is controlled by a refrigeration unit 500, refrigeration unit 500 is by cold fresh-keeping 504 heat exchange of refrigerated heat exchanger 501 and 0~10 DEG C, entirely
Region is bearing area.As shown in figure iD, 0~15 DEG C of freezer 505 is individually controlled by a refrigeration unit 500, refrigeration unit
500 are exchanged heat by refrigerated heat exchanger 501 and 0~15 DEG C freezer 505, and whole region is bearing area.As referring to figure 1E, 0~
15 DEG C of Administrative Areas 506 are individually controlled by a refrigeration unit, and refrigeration unit 500 is done by refrigerated heat exchanger 501 and 0~15 DEG C
Public region 506 exchanges heat, and whole region is bearing area.
The refrigerating method that can be seen that existing refrigeration storage system, with the cold consumption of disengaging goods, cooling capacity load is increased,
In order to adjust load, refrigeration host computer needs frequent starting, causes refrigeration host computer to be under bad working environments and runs, inefficiency, and
And the frequent start-stop of refrigeration host computer reduces the refrigeration host computer service life.The frequent starting of refrigeration host computer also results in temperature-fall period and does not connect
Continuous, temperature fall time is long, is unfavorable for accurately controlling library temperature.In order to maintain library temperature, refrigeration host computer longtime running is in the low negative of low-energy-efficiency
Lotus state causes the operational efficiency of refrigeration unit to be lower, and without being operate in optimum efficiency state, in turn results in load peak-valley difference
Greatly.
Evaporator is easy the non-uniform frost of knot, causes system loading to increase after defrosting cycle because temperature load changes greatly.
Meanwhile under existence conditions freezer peak modulation capacity it is weak, compressor is configured according to peak load, under part load condition because
Energy adjustment, such as hot-gas bypass etc. cause refrigeration host computer load efficiency low.
Also, in the prior art, the use temperature range of each freezer is constant, can not be changed to the humidity province of other purposes
Between.When multiple libraries, refrigeration unit number of units is more, higher cost.
In addition, the refrigeration pipeline of entire reservoir area is pressure duct, pressure duct range is too wide, is unfavorable for fire-fighting and maintenance.
It once revealing, can not be safeguarded by quick means, and then influence the use of entire freezer；And the leakage of refrigerant
It is easy to cause dangerous.
Meanwhile traditional air-cooled refrigeration modes, energy consumption cost is high, and stock drying loss is big, and quality cannot ensure.Cold wind
Machine cold supply system and the automatic defrosting as derived from it are to cause the temperature of ice house frequently main contributor of fluctuation.
Cooling supply distributor is that refrigeration storage system carries out cooling capacity distribution, to overcome the defect of prior art refrigerating method, firstly, needing
