Then A is set in order to improve cooling velocity change.For example, carrying out following control: improving the revolving speed of each fan, improve compressor 31
Operating frequency improves the revolving speed of the fan (not shown) of radiator (not shown), expands the aperture etc. of expansion valve (not shown).
On the other hand, if cooling velocity V is higher than fixed number a, the setting A(step S18 that (NO of step S17) is present is maintained).
In the refrigeration equipment of present embodiment, cooling velocity is kept constant as far as possible when carrying out supercooling.For this purpose, every
It is frozen the temperature of object 26 every stipulated time measurement, based on measurement result adjustment setting A.
In the following, measuring the temperature (step S20) for being frozen object 26 again using above-mentioned temperature sensor 34.Also, always
The measurement (NO of step S21) is carried out until by the stipulated time, after the stipulated time (YES of step S21), measurement cooling
Speed and compared with preset fixed number (from step S22 to step S25).
Here, fixed number b, c, d are being used from step S22 to step S25, the size relation of these fixed numbers is b < c < d.
If being less than the YES of fixed number b(step S22 by the cooling velocity that step S21 is calculated), since its speed is inadequate,
Therefore A(step S26 is set in order to improve cooling velocity change).The specific method for improving cooling velocity is as described above.
If cooling velocity is greater than b and is less than the YES of c(step S23), since cooling velocity is in suitable range, because
This maintains setting A(step S27).
If cooling velocity is greater than c and is less than the YES of d(step S24), since cooling velocity is too fast, reduce cold
But speed change setting A(step S28).For example, reducing the winding number of each fan, the operating cycle of compressor 31, drop are reduced
The winding number of the fan (not shown) of low heat emission device (not shown), the control for the aperture of diminution expansion valve (not shown) etc.
System.
If cooling velocity is greater than the YES of d(step S25), in this case, also due to cooling velocity is too fast, because
Setting A is set as initial value (minimum) by this.
In the present embodiment, it will utilize from step S21 to the measurement of step S25 and judge such as 4 (steps repeatedly
The NO of S30).Also, if such measurement and judgement carry out 4 times (YES of step S30), judge whether is setting A at this time
Reach maximum cooling (step S31).If setting A reaches maximum one (YES of step S31), setting A is returned to
Initial value (step S32).That is, setting A is reduced to floor level.Reason for this is that because setting A as most in step S31
Big situation is to indicate that being frozen object 26 is thicker food, and thick food in this way needs to drop for the generation for inhibiting watery blood to be lost
Low cooling velocity.
On the other hand, if setting A in step S31 is not maximum (NO of step S31), in order to will be from above-mentioned steps
S20 to step S31 such as 10 times repeatedly, these steps carry out 6 times (NO of step S33) again.This is because being frozen object 26 is
Relatively thin food, it is possible to further increase cooling velocity.
In other words above-mentioned control, in the present embodiment, is frozen the case where object 26 is thicker food and updates control
It 4 times repeatedly, is frozen the case where object 26 is relatively thin food and updates control 10 times repeatedly.Even if it is thick for being frozen object 26 as a result,
Food, can also carry out inhibit watery blood be lost generate supercooling.In addition, in the present embodiment, after step S33
Process, setting A is without change.
If above-mentioned measurement reaches 10 times (YES of step S33), until by the stipulated time, with status
Setting continue supercooling mode (NO of step S34, step S35).Also, if by certain time (step S34's
YES), then terminate supercooling mode, back to usually cooling.
Here, the stipulated time of step S34 is such as 75 minutes or so.In the flow chart, presets and carried out
During refrigerating mode, but it is also possible to be set to return to usual cooling according to the output of temperature sensor.
Referring to the flow chart of Fig. 6, in the following, to wind path shutter 18(when carrying out supercooling mode referring to the movement of Fig. 2)
It is illustrated.
According to the operation of user, when being moved to supercooling mode from usual cooling (step S51, the NO of step S52)
(YES of step S52), judges whether the room temperature of refrigerating chamber 3 is greater than 8 DEG C (step S53).Also, if the temperature of refrigerating chamber 3
Degree is greater than 8 DEG C (YES of step S53), then confirms wind path shutter 18(referring to Fig. 2) whether (step S58) is opened, if wind path
Shutter 18 opens (YES of step S58), then the state for maintaining its original.On the other hand, if wind path shutter 18 is closed
(NO of step S58) then opens wind path shutter 18 and cools down cold air importing refrigerating chamber 3.Thereby, it is possible to by refrigerating chamber 3
Temperature maintain suitable low-temperature condition.
On the other hand, if the temperature of refrigerating chamber 3 is lower than 8 DEG C (NO of step S53), and wind path shutter 18 closes (step
The NO of rapid S54), then the state for maintaining wind path shutter 18 to close is constant.
If wind path shutter 18 opens (YES of step S54), object is frozen using measured by temperature sensor 34
26 upper surface temperature is higher than 2 DEG C (YES of step S55), then closes wind path shutter 18(step S60).Thereby, it is possible to improve
The air quantity of upper layer freezing chamber 5 accelerates cooling velocity, realizes supercooling.
On the other hand, if food temperature is lower than 2 DEG C (NO of step S55), the temperature of refrigerating chamber is lower than 0 DEG C of (step S56
YES), then close wind path shutter 18(step S61), reduce the 2nd pressure fan 23 ability (step S62).Even if leading to as a result,
Cross and close wind path shutter 18 and increase the cold air that supply from blow-off outlet 28, also can by the ability of the 2nd pressure fan 23 of reduction,
And cooling velocity is kept constant.The above process carries out (step S57's until passing through the stipulated time (such as 75 minutes) always
NO).Thereafter, if having passed through stipulated time (YES of step S57), usual operating is performed to.Here, it also can be set to
Usual operating is returned to according to the output of temperature sensor.
