Control device C is input to determine each mode.
Next, illustrating that control device C controls the temperature display of temperature indicator 22 referring to Fig. 2 and Fig. 3.Fig. 2 is indicated
Function block relevant to the control of the temperature display of control device C.Control device C includes microcomputer, and in embodiment
In the case of, as its function, control device C has temperature arithmetical organ 31, hull shape correction mechanism 32, illumination correction mechanism
33 and night shield correction mechanism 34.
Wherein, hull shape correction mechanism 32 saves the hull shape correction value of the open Showcase 1.The hull shape
Correction value is determined intrinsic according to the hull shape of the open Showcase 1 (being upright shell under the case for this embodiment)
Correction value, first pass through experiment in advance and find out, in the case where upright shell, as shown in figure 3, being set as under each mode above-mentioned
Less than " 0.8 " of " 1 ".
In addition, illumination correction mechanism 33 saves the illumination correction value of the open Showcase 1.The illumination correction value is basis
The illuminating state of lighting device 12 and the correction value determined, depending on the quantity of lighting device 12, numerical value changes.It is also logical in advance
It crosses experiment and finds out, in the case where upright shell, as shown in figure 3, being set as " 1.2 " under day mode and light-modulating mode.
In addition, extinguishing under Night and illumination close pattern, therefore illuminates correction value and be set to " 0 ".
In addition, night shield correction mechanism 34 saves the night shield correction value of the open Showcase 1.The night shield
Correction value is the correction value for whether being covered and being determined according to night shield 21, first passes through experiment in advance and finds out, in upright shell
In the case of, as shown in figure 3, being set as " 1.0 " under Night.In addition, under the mode other than Night, night shield
21 can be crumpled up, therefore night shield correction value is set to " 0 ".
Also, the temperature arithmetical organ 31 of control device C is based on the blowout blowout temperature detected of temperature detector 26, inhales
Enter the inlet temperature detected of temperature detector 27, the hull shape correction value that hull shape correction mechanism 32 is saved, illumination
The night shield correction value that the illumination correction value and night shield correction mechanism 34 that correction mechanism 33 is saved are saved, operation
The average value of each shelf 11 and the temperature on parcel shelf 6 (being commodity display portion), and in the enterprising trip temperature of temperature indicator 22
Display output.
It is shown at this point, the temperature arithmetical organ 31 of control device C carrys out operation on temperature indicator 22 using following formula (1)
The temperature of output.That is, the temperature being shown on temperature indicator 22=blowout temperature+(inlet temperature-blowout temperature)/2 × shell
Shape correction value+illumination correction value+night shield correction value ... (1).
[(inlet temperature-blowout temperature)/2] of above-mentioned formula (1) are the average value of inlet temperature and blowout temperature difference, because
Outside air is involved in, and inlet temperature is higher than blowout temperature, and therefore [blowout temperature+(inlet temperature-blowout temperature)/2] are
The center of the up and down direction for the showroom 8 for instigating blowout temperature at blow-off outlet 16 to rise towards the inlet temperature at suction inlet 17
Temperature.[(inlet temperature-blowout temperature)/2] in [should blowing out temperature+(inlet temperature-blowout temperature)/2] are multiplied by shell
Shape correction value, but in the case where the upright shell of embodiment, it is set as " 0.8 " less than " 1 " as described above, because
This becomes the temperature of the blowout temperature of blow-off outlet 16 more closer than the center of up and down direction.
Here, in the case where upright shell as Fig. 1, anyway, the volume of the outside air from suction inlet 17
Entering amount all can become more, therefore inlet temperature can be got higher.Therefore, in the feelings of only [blowout temperature+(inlet temperature-blowout temperature)/2]
Under condition (that is, hull shape correction value is " 1 "), there is the temperature calculated than the temperature on actual each shelf 11 or parcel shelf 6
High tendency is spent, but by the way that hull shape correction value is set as " 0.8 " less than " 1 " as the embodiment, thus with [blowout temperature
Degree+(inlet temperature-blowout temperature)/2 × hull shape correction value] temperature that is calculated reduces with closer to blowout temperature,
To which close to the average value of the temperature on each shelf 11 or parcel shelf 6, (" 0.8 " is to become each shelf with the temperature calculated
11 or the temperature on parcel shelf 6 average value mode by experiment find out and determine).
In addition, under the day mode or light-modulating mode that lighting device 12 is lighted, because hot caused by lighting device 12
It influences, the temperature on each shelf 11 or parcel shelf 6 rises.Therefore, merely with [blowout temperature+(inlet temperature-of above-mentioned formula (1)
Blow out temperature)/2 × hull shape correction value], will lead to the temperature calculated lower than on actual each shelf 11 and parcel shelf 6
Temperature average value, but will [blowout temperature+(inlet temperature-blowout temperature)/2 × hull shape correction value] in the formula (1)
In addition " illumination correction value ", moreover, the illumination correction value is set as " 1.2 " in day mode and light-modulating mode, therefore operation
Temperature out is got higher, thus close to the temperature on actual each shelf 11 and parcel shelf 6 average value (" 1.2 " be with transport
The mode that the temperature of calculating becomes the average value of each shelf 11 or the temperature on parcel shelf 6 is found out and is determined by experiment).
Moreover, no outside air is involved in suction inlet 17 (or die-offing) when night shield 21 is covered, therefore suck temperature
Degree decline.Therefore, merely with [blowout temperature+(inlet temperature-blowout temperature)/2 × hull shape correction value] of above-mentioned formula (1)
And illumination correction value, it will lead to the temperature calculated lower than actual each shelf 11 and the average value of the temperature on parcel shelf 6, but
[blowout temperature+(inlet temperature-blowout temperature)/2 × hull shape correction value+illumination correction value] is added into " night in formula (1)
Between shield correction value ", moreover, the night shield correction value is set as " 1.0 " under Night, therefore the temperature calculated becomes
Height, so that (" 1.0 " are the temperature to calculate close to the average value of the temperature on actual each shelf 11 and parcel shelf 6
The mode of average value as the temperature on each shelf 11 or parcel shelf 6 is found out and is determined by experiment).
Also, control device C will be output to temperature by the temperature display that temperature arithmetical organ 31 calculates as described above
It spends on display 22.In this way, control device C is based on the blowout blowout temperature detected of temperature detector 26, sucking in the present invention
The inlet temperature detected of temperature detector 27 and pre-determined hull shape correction value, illumination correction value, night shield are repaired
Positive value carrys out the temperature on each shelf 11 of operation or parcel shelf 6 (commodity display portion), and is shown on temperature indicator 22, because
This variation that can follow the cooler environments such as the presence or absence of the lighting/extinguish of hull shape and illumination, night shield comes accurately
Show the temperature on each shelf 11 or parcel shelf 6.
Especially it can be realized correct temperature management in open Showcase 1 as the embodiment as a result,.In addition,
Multiple shelves 11 or parcel shelf 6, but the temperature on each shelf 11 of control device C operation or parcel shelf 6 are provided in showroom 8
Average value and shown on temperature indicator 22, therefore can show and be with the temperature on each shelf 11 or parcel shelf 6
The temperature of representative.
Especially, by the temperature shown on temperature indicator 22 according to formula above-mentioned (1) come operation, thus, it is possible to
Enough temperature shown on temperature indicator 22 closer to each shelf 11 or the temperature on parcel shelf 6, the temperature are to utilize shell
Shape correction value, illumination correction value and night shield correction value are to indicating [blowing for blow-off outlet 26 and the medium temperature of suction inlet 27
Temperature+(inlet temperature-blowout temperature)/2 out] it is modified obtained temperature.
At this point, by making hull shape correction value in the case where upright shell as the embodiment less than 1, thus right
In upright shell, the temperature of display can be made closer to blowout temperature, exclude shadow caused by being involved in of the outside air because of lower part
It rings (inlet temperature gets higher and displays temperature is caused to become the influence higher than the temperature on each shelf 11 or parcel shelf 6), so as to
Enough temperature accurately shown on each shelf 11 or parcel shelf 6.
In addition, as previously mentioned, illumination correction value is shown on temperature indicator 22 towards raising when lighting device 12 is lighted
The direction of temperature work, therefore each shelf 11 or parcel shelf 6 risen by the influence of illumination can be more accurately displayed
On temperature.
Moreover, night shield correction value is shown on temperature indicator 22 towards raising when night shield 21 is covered
The direction of temperature is worked, therefore can be excluded night shield 21 and be covered and be involved in without outside air, thus under inlet temperature
The influence of drop, it is thus possible to the temperature on each shelf 11 or parcel shelf 6 be more accurately displayed.
In addition, the control device C of embodiment calculate be shown in the temperature on temperature indicator 22 when, for whether using
Each correction value above-mentioned is able to carry out switching.As a result, according to the management method of user, switching is corrected using hull shape
Value, illumination correction value, night shield correction value, or carry out operation merely with blowout temperature and inlet temperature, so that convenience mentions
It is high.
[embodiment 2]
Next, illustrating another embodiment of temperature display control of the control device C to temperature indicator 22.Function at this time
Energy square includes the dotted line in Fig. 2.
In case of the present embodiment, the temperature arithmetical organ 31 of control device C carrys out operation in temperature using following formula (2)
The temperature of output is shown on display 22.That is, the temperature being shown on temperature indicator 22=in-cabinet temperature+blowout temperature+
(inlet temperature-blowout temperature)/2 × hull shape correction value }/2+ illumination correction value+night shield correction value ... (2)
With formula (1) the difference is that { in-cabinet temperature+blowout temperature+(inlet temperature-blowout temperature in above-mentioned formula (2)
Degree)/2 × hull shape correction value }/2.It should { in-cabinet temperature+blowout temperature+(inlet temperature-blowout temperature)/2 × hull shape
Correction value }/2 be in in-cabinet temperature detector 28 [in-cabinet temperature] detected and the formula (1) [blowout temperature+(sucking temperature
Degree-blowout temperature)/2 × hull shape correction value] average value.That is, becoming in the case where open Showcase 1 of Fig. 1
With the central average value to the blowout temperature of blow-off outlet 16 close temperature and in-cabinet temperature of the up and down direction from showroom 8.
The in-cabinet temperature detected of in-cabinet temperature detector 28 becomes the temperature lower than the other parts in showroom 8, but
Invariably the in-cabinet temperature is the temperature in actual showroom 8.Also, the temperature in actual showroom 8 show because
Outside air from the intrusion of opening 7 or the discrepancy etc. of commodity influence (external disturbance) cause only by blow out temperature or inlet temperature without
The variation that method is grasped.
