The operating voltage of system is adjusted, to control the refrigeratory capacity of refrigeration system；When current breast milk temperature reaches breast milk refrigeration mark
Quasi- temperature (such as 6 DEG C) automatically controls refrigeration system and enters half-power refrigerating state, reaches refrigerated storage temperature point, and refrigeration system produces
Cooling capacity QcWith leaking heat QLDynamic equilibrium (Qc=QL), wherein refrigeration work consumption Pi(Pi=Qc/ cop, cop are coefficient of refrigerating performance) meeting
With the corresponding adjust automatically of environment temperature.After cooling capacity dynamic equilibrium, breast milk is stablized in corresponding equilibrium temperature point, and stores certain
Cooling capacity.After the new breast milk bag of subsequent time is placed into the breast milk storage chamber of breast milk cold storage plant, the breast milk temperature of corresponding new breast milk
To controller, the current breast milk temperature and temperature threshold range (for example, 2~6 DEG C) are compared by controller for degree conduction,
Half-power refrigerating state of the refrigeration system by dynamic equilibrium early period when is controlled if more than upper limit threshold (such as 6 DEG C) to adjust to total power
State.It should be noted that two bags of breast milks are symmetrically placed with respect to the refrigerator of refrigeration system in liner, the breast milk temperature of new placement
Degree is higher than the temperature of first bag of breast milk of storage early period, and temperature difference automatically causes refrigeration system to distribute two bags of breast milk difference cooling capacity
(Wherein Q, Δ T, RTRespectively cooling capacity, the temperature difference and thermal resistance).
Assuming that temperature when first bag of breast milk cold storage procedure or refrigeration balance is T1；The cryogenic temperature of refrigeration system is T0, the
Temperature when two bags of breast milks are put into is T2, the refrigerator of refrigeration system to the synthesis thermal resistance between breast milk bag is RT0, the first breast milk
The synthesis thermal resistance of bag to the second breast milk bag is RT12, refrigerating capacity when refrigeration system full power operation is Q0.Under the operating condition, first
The cooling capacity that breast milk bag is obtained from the cool-guiding device of refrigeration systemThe cooling capacity that second breast milk bag is obtained from cool-guiding deviceCooling capacity is obtained from the first breast milk bag simultaneouslyThen have: Q0=Q1+Q2, due to just placed second
Breast milk bag temperature T2(such as 35 DEG C) are much higher than the temperature T of the first breast milk bag refrigerated1(such as 6 DEG C) are close to T0, i.e. T2>T1, because
This Q2>Q1.Due to RT12The thermal-conduction resistance between cold gallbladder, much larger than the thermal resistance R of cool-guiding device to breast milk bagT0(i.e. RT12>RT0)。
It can thus be concluded that: by breast milk storage chamber, cool-guiding device as cooling capacity distributing buffer device, the cooling capacity that refrigeration system generates is exhausted
Most of (cooling capacity etc. including the storage of breast milk storage chamber) is delivered to second bag of breast milk refrigeration, it is made to be cooled to best temperature as early as possible
Degree.It should be noted that first bag of breast milk temperature slightly rises fluctuation in entire process of refrigerastion.It, can to reduce temperature fluctuation
Using multiple refrigerator technical solutions, the refrigerating capacity of corresponding refrigerator can be individually adjusted to the breast milk bag of different location,
It will affect and be preferably minimized.
In one example, the self-adaptive temperature adjusting method of a kind of breast milk cold storage plant provided by the present application, can to compared with
Wide environmental temperature (- 30 DEG C~+30 DEG C) operating condition carries out automatic adjusument.Wherein, standard temperature is refrigerated when environment temperature is higher than breast milk
When spending, controller controls the operating voltage of refrigeration system according to the current breast milk temperature being connected in a manner of PID, and then controls
The refrigeratory capacity of refrigerator (TEC) completes temperature control.When environment temperature is lower than breast milk refrigeration normal temperature, the control in a manner of PID
The operating voltage of refrigerator processed, gradually reduces with cryogenic temperature, until decline minimum value (0~0.2V), corresponding refrigeratory capacity by
Step is reduced to minimum, i.e., entire refrigeration system is reduced with environment temperature, and refrigerating capacity is gradually minimum, until being reduced to zero.It realizes
Breast milk refrigerated storage temperature ambient temperature is widely varied the self adaptive control of operating condition, it is ensured that the constant temperature of breast milk refrigeration.
