During limit temperature, (moment t2, t5) stops.
During flashboard 6a is during compressor 1 operating, the temperature according to cold room is controlled.Specifically, in cold room extremely
Set lower limit temperature less, during flashboard 6a is controlled so as to during compressor 1 operates, when the temperature of cold room is less than lower limit temperature
(in the example in fig. 4, being moment t1) becomes fully closed.In addition, flashboard 6a is controlled so as to when compressor 1 has started (Fig. 4's
In example, it is moment t3, t6) become standard-sized sheet.
During temperature constant in the present embodiment controls, during compressor 1 stops in, also according to the temperature of cold room
Degree, changeably controls the aperture of flashboard 6a with multistage or no stage.Accordingly, in during compressor 1 stopping, cold room
Temperature is maintained more constant.If comparing to Fig. 4 (a) and Figure 13 (a), in knowing during compressor 1 stops, cold room
Temperature be maintained more constant.
Then, the other example controlling as the temperature constant in present embodiment, to the opening time by flashboard 6a
Or the temperature constant control that the regulation of shut-in time is carried out illustrates.In this example, flashboard 6a is for example controlled in standard-sized sheet
Or this two positions fully closed, in the open and-shut mode (fully open/closed) of each shorter time-switching flashboard 6a.By regulator
Plate 6a becomes at least one party's (for example, opening time) that the opening time of standard-sized sheet and flashboard 6a become in the fully closed shut-in time,
Adjust opening time and the ratio of shut-in time (opening and closing dutycycle).Accordingly, each being provided with the supply wind path 12 of flashboard 6a is single
The air quantity of position time is adjusted to variable.
Fig. 5 is the flow chart representing the example of the flow process of temperature constant control process being executed by control unit 50.Shown in Fig. 5
Process be with compressor 1 stop for rise thus start process.Fig. 6 be represent this temperature constant control in one of action

One) temperature, (c) represent compressor 1 operating condition (ON/OFF), (d) represent cold room flashboard 6a aperture.
First, in step s 201, pressure fan 5 is made to drive.In the case that pressure fan 5 has driven, former state is maintained to continue
Continuous driving.
Then, in step S202, obtain the target temperature Tm_a of storeroom A8a set in advance and by temperature sensor
Detection temperature T_a of 21 couples of storeroom A8a.And, calculate their temperature difference (Tm_a-T_a), judge temperature difference (Tm_a-T_
A) whether big than 0.Because in the case that temperature difference (Tm_a-T_a) is bigger than 0 ((Tm_a-T_a) ＞ 0), being judged as storeroom
A8a is cooled excessively, so, the opening time of flashboard 6a is reduced Δ t (step S203).Hereafter, enter step S206.Another
Aspect, in the case that temperature difference (Tm_a-T_a) is below 0, enters step S204.
In step S204, judge whether temperature difference (Tm_a-T_a) is less than 0.Because comparing 0 in temperature difference (Tm_a-T_a)
In the case of little ((Tm_a-T_a) ＜ 0), it is judged as that storeroom A8a cooling is not enough, so, the opening time of flashboard 6a is increased
Δ t (step S205).Hereafter, enter step S206.On the other hand, in the case of due to being 0 in temperature difference (Tm_a-T_a), inspection
Testing temperature T_a is consistent with target temperature Tm_a, so, maintain the opening time of current flashboard 6a, enter step S206.
In step S206, judge whether compressor 1 starts.In the case that compressor 1 has started, return common control
System, in the case that compressor 1 does not start, return to step S202.Accordingly, in during compressor 1 stopping, step is repeated
The process of rapid S202～S205, until compressor 1 starts.That is, in during compressor 1 stopping, the opening and closing dutycycle of flashboard 6a
According to the temperature of storeroom A8a, be controlled so as to the multistage or with no stage variable (with reference to Fig. 6 (d)).Here, flashboard 6a
Variation delta t of opening time can be fixed value or the value correspondingly changing with temperature difference (Tm_a-T_a).
Then, to controlling, make more constant former of temperature of storeroom by the temperature constant in present embodiment
Reason illustrates.During due to stopping in compressor 1, the cooling capacity of freeze cycle is 0, so it is impossible to entering to be about to freeze
Circulate the cooling of the air using as Cooling and Heat Source.However, being attached to cooler in during due to can operating in compressor 1
4 frost, cooler 4 thermal capacity of itself use as Cooling and Heat Source, so, in cooling chamber 7, even if in compressor 1 withholding period
Between in it is also possible to somewhat air be cooled down.Accordingly, by being imported the cooling air of cooling chamber 7 with suitable air quantity
Storeroom, can suppress the rising of the temperature of storeroom.Therefore, in during compressor 1 stopping, by the temperature according to storeroom
Degree, changeably controls the air quantity of the cooling air of whereabouts storeroom with multistage or no stage, such as Fig. 4 (a) and Fig. 6 (a)
Shown, can more consistently keep the temperature of storeroom.Its result is can more consistently to keep storing indoor food
Temperature, be prevented from food quality reduce.
