In some embodiments of the invention, at least one temperature-detecting device 120 can be provided with storing compartment 10, and
It is configured to detect the compartment temperature of storing compartment 10 and detects whether to be put more than the heat load of default first temperature threshold
Enter storing compartment 10.It should be noted that temperature-detecting device 120 can be infrared temperature sensor, or sensitivity
Other high temperature-detecting devices, its is specifically chosen to belong to known category, is it will be understood by the skilled person that therefore here not
Repeat again.
In some embodiments of the invention, storing compartment 10 can have at least one board putting things 100, and be configured to store up
The inner space of thing compartment 10 is divided into many sub- compartments 101.At least one air outlet can be also respectively provided with per individual sub- compartment 101
110, and be configured to make supply cooling air-flow to storing compartment 10 evenly into each sub- compartment via air-supply passage 50
101.Preferably, the air outlet 110 in each sub- compartment 101 can be multiple, and be evenly distributed in the inwall of sub- compartment 101
On, so that the compartment temperature of each sub- compartment 101 is synchronously reduced, so as to reach more preferable cooling effect.
It is interior per individual sub- compartment 101 to be also provided with the inspection of at least one temperature in some currently preferred embodiments of the present invention
Device 120 is surveyed, and is configured to detect the compartment temperature of its sub- compartment 101 being located and has been detected whether more than default first
The heat load of temperature threshold is put in the sub- compartment 101 at its place.
In some embodiments of the invention, supply air system 20 can be configured to, when the compartment temperature of whole sub- compartments it is little
When default second temperature threshold value, supply air system 20 is not blown or out-of-blast.When the compartment temperature of whole sub- compartments it is equal
More than or equal to second temperature threshold value, and when all interior does not have heat load between son, the first air supply pattern starts, so that all
The compartment temperature of sub- compartment is decreased to less than second temperature threshold value.When there is heat load interior between some or all of son, second
Air supply pattern starts, so that the temperature of heat load is decreased to less than second temperature threshold value.Wherein, second temperature threshold value is warm less than first
Degree threshold value.
That is, in the present embodiment, when the compartment temperature of each sub- compartment 101 in storing compartment 10 is satisfied by storage
During condition needed for article (i.e. its compartment temperature is less than second temperature threshold value), supply air system 20 is not blown, and if now blowing
System 20 is blown, then out-of-blast.Now the first return air channel 31 and the second return air channel 32 are blocking state, blower fan
50 and cooler 41 do not work.It is understood that when the compartment temperature of each sub- compartment 101 in storing compartment 10 is respectively less than
During second temperature threshold value, can not possibly there is heat load of the temperature more than the first temperature threshold in it.
When the condition needed for the compartment temperature of some or all of sub- compartment of storing compartment 10 is unsatisfactory for storage article,
Supply air system 20 starts work.
Specifically, if now there is no temperature in each sub- compartment 101 of storing compartment 10 more than the first temperature threshold
Heat load, then supply air system 20 supply cooling air-flow, as only the first return air to storing compartment 10 by the first air supply pattern
The air supply pattern of the conducting of passage 31, now the second return air channel 32 is blocking state, blower fan 50 and the equal startup optimization of cooler 41.
Under the first air supply pattern, cooling air-flow by the first return air channels of Jing 31 to be only back to cooling chamber 40 and cold via cooler 41
But the first return air stream composition, its temperature is relatively low, such that it is able to promptly by between each sub- compartment 101 of storing compartment 10
Room temperature is down to the condition met needed for storage article.It is understood that when indoor equal between all sons of storing compartment 10
Do not exist temperature more than the first temperature threshold heat load when, it is only necessary to supplying cooling air-flow in short time to storing compartment 10 is
The compartment temperature of its all sub- compartment can be down to below second temperature threshold value, therefore be not in the thing in storing compartment 10
The problem that product are frozen in because of long-time contact sub-cooled air-flow.
If now there are heat of the temperature more than the first temperature threshold in some or all of sub- compartment of storing compartment 10
Load, then supply air system 20 supplies cooling air-flow, as the first return air channel 31 by the second air supply pattern to storing compartment 10
The air supply pattern being both turned on the second return air channel 32, now blower fan 50 and cooler 41 also equal startup optimization.In the second air-supply
Under pattern, cooling air-flow is to be mixed and formed by the first return air stream and the second return air stream, and its temperature is higher than the first air-supply mould
The temperature of the cooling air-flow under formula, such that it is able to realize ensure between some or all of son of storing compartment 10 indoor temperature compared with
In the case that low cold load is not frozen in, the higher heat load of temperature is set quickly to be down to the temperature met needed for storage article.
It is understood that when the temperature of the higher heat load of temperature is down to below second temperature threshold value, positioned at same storing compartment
The temperature of the relatively low cold load of temperature in 10 is also inevitable below second temperature threshold value, so that storing compartment 10 is all
The compartment temperature of sub- compartment is satisfied by the condition needed for storage article.
In some embodiments of the invention, when storing compartment 10 is refrigerator room of the storage temperature more than 0 DEG C, the
Two temperature thresholds can be the temperature of general wind cooling refrigerator refrigerator room, that is to say the arbitrary temperature within the temperature range of 2 DEG C～8 DEG C
Degree.For example second temperature threshold value can be set as 4 DEG C, 5 DEG C or 6 DEG C according to the demand of user.First temperature threshold can be
More than arbitrary temperature of set second temperature threshold value.For example when second temperature threshold value is set as 7 DEG C, then the first temperature threshold
Value can be 10 DEG C, 20 DEG C or 30 DEG C etc. the temperature values more than 7 DEG C, when second temperature threshold value is set as 3 DEG C, then the first temperature
Threshold value can be 4 DEG C, 8 DEG C or 12 DEG C etc. the temperature values more than 3 DEG C.It should be noted that the first temperature threshold is also dependent on tool
The type set of the temperature-detecting device that body is chosen is other the suitable temperature values more than second temperature threshold value.
In some embodiments of the invention, supply air system 20 may also include cooling air-flow temperature sensor 510.Cooling gas
Stream temperature sensor 510 may be disposed in air-supply passage 50, and be configured to sense the temperature of cooling air-flow.
In some embodiments of the invention, the first return air air door 310 and the second return air air door 320 are in the second air supply pattern
Under can be configured to：When the temperature of cooling air-flow is more than the upper limit threshold of default 3rd temperature range or less than the 3rd temperature range
Lower threshold when, can adjust the aperture of the first return air air door 310 and/or the second return air air door 320, change via the first return air
Passage 31 and the air-flow ratio of cooling chamber 40 is back to via the second return air channel 32, so that the temperature of cooling air-flow is maintained at
In three temperature ranges.Wherein, the upper limit threshold of the 3rd temperature range is less than second temperature threshold value.
That is, in the present embodiment, when the temperature of cooling air-flow it is less than the upper limit threshold of the 3rd temperature range and big
When the lower threshold of the 3rd temperature range, the aperture of the first return air air door 310 and the second return air air door 320 keeps constant,
So that the temperature of cooling air-flow is maintained in the 3rd temperature range, until the compartment temperature of all sub- compartments is equal in storing compartment 10
It is down to below second temperature threshold value.
When cooling air-flow temperature more than the 3rd temperature range upper limit threshold when, adjust the first return air air door 310 and/or
The aperture of the second return air air door 320, so as to be back to first return air stream and Jing of cooling chamber 40 via the first return air channel 31
The ratio increase of the second return air stream of cooling chamber 40 is back to by the second return air channel 32, so that the temperature of cooling air-flow
It is reduced in the 3rd temperature range.Specifically, if the aperture of the first return air air door 310 is not up to maximum, the first return air is increased
The aperture of air door 310, to increase the first return air stream into cooling chamber 40, until the temperature of cooling air-flow to be reduced to the 3rd warm
In the range of degree.If the aperture of the first return air air door 310 has reached maximum, but the temperature of cooling air-flow still greater than the 3rd temperature range
Upper limit threshold, then reduce the aperture of the second return air air door 320, to reduce the second return air stream into cooling chamber 40, until
The temperature of cooling air-flow is reduced in the 3rd temperature range or the aperture of the second return air air door 320 reaches minimum.
Correspondingly, when the temperature of cooling air-flow is less than the lower threshold of the 3rd temperature range, the first return air air door is adjusted
310 and/or second return air air door 320 aperture, so as to be back to the first return air of cooling chamber 40 via the first return air channel 31
The ratio of air-flow and the second return air stream that cooling chamber 40 is back to via the second return air channel 32 reduces, so that cooling gas
The temperature of stream is increased in the 3rd temperature range.Specifically, if the aperture of the second return air air door 320 is not up to maximum, increase
The aperture of the second return air air door 320, to increase the second return air stream into cooling chamber 40 until the temperature of cooling air-flow is raised
To the 3rd temperature range.If the aperture of the second return air air door 320 has reached maximum, but the temperature of cooling air-flow still less than the 3rd
The lower threshold of temperature range, then reduce the aperture of the first return air air door 310, to reduce the second return air gas into cooling chamber 40
Stream, the temperature of cooling air-flow is increased in the 3rd temperature range or the aperture of the first return air air door 310 reaches minimum.
That is to say, two return air damper configurations into, cooling air-flow temperature more than the 3rd temperature range upper limit threshold
Or less than the 3rd temperature range lower threshold when, need increase aperture return air air door be adjusted first, until cooling gas
The temperature of stream is reduced or is increased in the 3rd temperature range.If the aperture of the return air air door has reached maximum, but cooling air-flow
Temperature still greater than the upper limit threshold or the lower threshold still less than the 3rd temperature range of the 3rd temperature range, then need reduction to open
Another return air air door of degree is just adjusted, until the temperature of cooling air-flow reduce or be increased to the 3rd temperature range it is interior or
The aperture of another return air air door reaches minimum.Thus, may be implemented in and change the first return air stream and the second return air stream
While ratio is so that chilling temperature is raised and lowered to the 3rd temperature range, cooling air-flow as much as possible is supplied to storage
In thing compartment 10, so as to shorten the working time of supply air system, the refrigerating efficiency of wind cooling refrigerator 1 is improve, and improve its section
The ability that can be lowered consumption.
It should be noted that the selection of the 3rd temperature range need to meet its upper limit threshold less than default second temperature threshold
The condition of value.That is to say, when second temperature threshold preset is 3 DEG C, the upper limit threshold of the 3rd temperature range may be less than 3 DEG C
