Describe the operation principle and the flow process of the utility model one specific embodiment in detail below in conjunction with Fig. 2-4.At first, cold-storage operating mode (Fig. 2) is described.In order to make full use of the cheap advantage of night dip phase electricity price, the cold-storage operating mode is generally carried out at night.Starting refrigeration unit 2 freezes, open electric check valve 8, make a in the triple valve 4, the c interface is communicated with, start refrigerating medium conveying device 3, thereby refrigerating medium such as ammoniacal liquor or ethylene glycol are driven, and the low-temperature receiver (as evaporimeter) through refrigerating plant 2 passes through electric check valve 8 again, triple valve a, c interface, enter in the cold-storage jar 1, formation circulates, thereby the cold of refrigerating medium constantly is stored in the cold-storage ball.When the temperature in the cold-storage jar 1 is reduced to the value of setting, by the demonstration of temperature sensor or thermometer 14, promptly can be manually or program control cold-storage unit 2 and refrigerating medium supply unit 3 and the electric check valve 8 of closing.Like this, the cold-storage operating mode finishes.The front is mentioned, the rated power of refrigeration unit design of the present utility model can suitably reduce, reason be night network load low, electricity price is cheap, so the cold-storage operating mode can not pursued speed, promptly can carry out cooling operation by All Through The Night, so power can design very for a short time, to save equipment investment.
Put cold operating mode referring again to Fig. 3 explanation.When putting cold operating mode, refrigeration unit is not generally worked, the b of triple valve 4, and the c interface is communicated with, start the second refrigerating medium delivery pump 5, form circulating of a refrigerating medium with heat exchanger 6 and cold-storage jar 1,, start water pump 7 according to the indication of the temperature sensor in the freezer or thermometer 13 and humidity sensor 10, thereby clean water is extracted out from the pond, after heat exchanger 6 is cooled cooling, spray in the freezer by spray equipment 12, reach the purpose of cooling and controlled humidity.
Referring to Fig. 4 emergent operating mode is described.When temperature in the freezer and cold-storage jar temperature are higher than set-point simultaneously, illustrate that the cold that only depends in the cold-storage jar can support that no longer temperature, humidity remain on the set-point in the freezer, need to start refrigerating plant 2 and guarantee the normal operation of freezer so that cold to be provided.At this moment, make a of triple valve 4, the b interface is communicated with, and opens valve 8, starts refrigeration unit 2, and refrigerating medium conveying device 3, the second refrigerant pumps 5 or open pipeline with pump 5 three-way cut-off valves in parallel realize that direct heat exchanger 6 provides cold.
Thus, also can tell people, during the capacity of design cold-storage jar, rule is that the cold-storage ability of cold-storage jar should satisfy the freezer required cold that runs well by day.
