103 temperature of accurate bottom condenser.Further, air blower 104 can be configured to be greater than ring when the temperature of bottom condenser 103
When border temperature reaches preset first difference, controlled starting is to carry out forced heat radiation to compressor bin 100.Bottom condenser at this time
103 only cannot effectively radiate under the action of cooling blower 102, and the unlatching of air blower 104 effectively can promote high temperature air to add
Speed outflow compressor bin 100, avoids frequency-changeable compressor 101 or condenser from breaking down because temperature is excessively high.
It that is to say, refrigeration effect, compressor bin needed for the heat exchange efficiency of refrigeration system meets refrigerating device 1
When temperature is relatively low in 100, air blower 104 can be not turned on, and only be carried out by cooling blower 102 to bottom condenser 103 scattered
Heat reduces noise with energy saving.
Specifically, first difference DELTA T1It can be the arbitrary temp value between 7 DEG C to 13 DEG C, such as can be 7 DEG C, 8
DEG C, 9 DEG C, 10 DEG C, 11 DEG C, the temperature values such as 12 DEG C or 13 DEG C.
Further, air blower 104 may be additionally configured to be down to the difference with environment temperature when the temperature of bottom condenser 103
Less than preset second difference DELTA T2When, it is out of service, only bottom heat radiation region is carried out by cooling blower 102 ventilation is accelerated to dissipate
Heat with energy saving and reduces noise.Specifically, second difference DELTA T2Than the first difference DELTA T1Slightly lower 2 DEG C to 4 DEG C to keep away
Exempt from air blower 104 to be opened and closed repeatedly.Second difference DELTA T2It can be specifically the arbitrary temp value between such as 5 DEG C to 10 DEG C, example
It such as can be 5 DEG C, 6 DEG C, 7 DEG C, 8 DEG C, 9 DEG C, 10 DEG C or 11 DEG C temperature values.It should be noted that when, the above second difference DELTA T2
Selection need according to the first difference DELTA T1Selection be determined, if the first difference DELTA T1It is 10 DEG C, then the second difference DELTA T2Only
It can be other numerical value lower than 10 DEG C.Preferably, the second difference can be lower than 3 DEG C of the first difference, such as the first difference DELTA T1
When being 10 DEG C, the second difference DELTA T2It can be 7 DEG C.
In some embodiments of the invention, air blower 104 can also pre-cooling.Specifically, when refrigerating device 1 is opened
When the refrigeration that begins, cooling blower 102 is configured to start operation, air blower after frequency-changeable compressor 101 ran for the first starting time
104 are configured to start operation after cooling blower 102 ran for the second starting time.

Such as, 0.2min, 0.3min, 0.4min, 0.5min or 0.6min etc..First dwell time can be identical with the second dwell time
It can be different.
It that is to say, after frequency-changeable compressor 101 stops working, air blower 104 can be after continuing to blow a short period first
Row stops.Cooling blower 102 is out of service after can continuing again a short period after the stopping of air blower 104.Due to being provided with cross
To the transverse opening 106 for running through compressor bin 100, either frequency-changeable compressor 101 or the heat of the generation of bottom condenser 103
(hot-air) is easier to outflow compressor bin 100.And then after frequency-changeable compressor 101 is shut down, the heat of generation in compressor bin 100
It measures limited, only promotes air flowing in compressor bin 100 that can meet cooling requirements by the cooling blower 102 of cross blowing,
The air blown directly can distribute outflow from laterally outlet.It is outside that laterally outlet is approximately perpendicular to without continuous service as a result,
The air blower 104 of air-supply, can meet the radiating requirements of compressor bin 100 at this time.
Certainly, if the temperature of compressor bin 100 is not decreased obviously after the stopping of air blower 104.Air blower 104 can also root
It is again started up according to the difference of bottom condenser 103 and environment temperature, to accelerate to radiate.

In the hinge box of the chamber door of cabinet 10, to obtain real-time environment temperature, especially apart from the closer region of refrigerating device 1
Environment temperature.
In some embodiments of the invention, refrigerating device 1 has free radiating mode and insertion radiating mode, and
The difference that position can be arranged according to it switches between both radiating modes.Specifically, when refrigerating device 1 is run on certainly
When by radiating mode, side condenser 105 is less than or equal to preset first upper limit threshold T in environment temperature1When controlled operation.
When refrigerating device 1 runs on insertion radiating mode, side condenser 105 is less than or equal to preset the in environment temperature

Shi Buhui improves the usage comfort of user because high temperature experiences discomfort.In addition, when refrigerating device 1 is in Embedded
When installation condition, the side temperature of overheat also will affect the wall of its insertion or the heated situation of closet, lead to wall or closet
Discoloration or deformation.It is also correspondingly provided with safe temperature as a result, that is to say the second upper limit threshold T2.Embedded installation site makes
It is smaller to obtain influence of 1 side wall temperatures of refrigerating device to environment temperature, therefore the second upper limit threshold T2Can be correspondingly higher than
One high limit temperature threshold T1。
In some embodiments of the invention, refrigerating device 1 may also include at least three range sensors 400.Tool
Body, referring to fig. 2 with 3, wherein three range sensors 400 can be respectively arranged at the left side, right side and rear side of cabinet 10, with point
It Jian Ce not the distance between refrigerating device 1 and the wall and/or the cabinet body that are located at its two sides and rear side.Specifically, a side

One side range sensor 400 may be provided near the lower part of side plate, such as compressor bin 100.The range sensor of rear side
400 are mountable to the backboard of 1 cabinet 10 of refrigerating device close to intermediate position.
In some embodiments of the invention, when refrigerating device 1 and between its two sides wall and/or cabinet body
Distance is less than or equal to first distance D1, and refrigerating device 1 with to be located at the distance between rear side wall and/or cabinet body small
In or equal to second distance D2When, then the operation of refrigerating device 1 is embedded in radiating mode.
When refrigerating device 1 is greater than first distance D with the distance between its two sides wall and/or cabinet body is located at1Or it is cold
It hides refrigerating plant 1 and is greater than second distance D with the distance between rear side wall and/or cabinet body is located at2When, refrigerating device 1

It that is to say, only when two sides and rear portion, which exist, blocks, refrigerating device 1 is just judged as positioned at insertion
State, and radiated with being embedded in radiating mode.When certain side of refrigerating device 1 or back are at a distance from wall or cabinet
It is remote enough, then it can be considered at mode of freely standing still for a long while, and radiate with free radiating mode.It is cold that side is reduced as a result,
105 longtime running of condenser prevents user when picking and placing article or mobile touching refrigerating device 1 to ambient temperature effect,
Uncomfortable possibility is generated because 10 temperature of cabinet is excessively high.
Specifically, first distance D1Can be 8mm to the arbitrary value between 12mm, for example, can for 8mm, 9mm, 10mm,
11mm or 12mm etc..Second distance D2Can be 12mm to the arbitrary value between 17mm, for example, can for 12mm, 13mm, 14mm,
15mm, 16mm or 17mm etc..In some currently preferred embodiments of the present invention, first distance D1It may be configured as 10mm, second distance D2
It can correspondingly be set as being greater than first distance D115mm.It that is to say, pay the utmost attention to the space size of 1 side of refrigerating device,
To guarantee that the temperature of side condenser 105 will not influence the comfort that user uses.
In other embodiments of the invention, it can also be passed through after refrigerating device 1 completes installation placement by user
The radiating mode of control signal selection refrigerating device 1.
Control method for above-mentioned refrigerating device of the invention is suitable for controlling aforementioned refrigerating device not
Heat dissipation is aerated by ventilation and heat mode appropriate under operating status, control method may include to air blower 104 and side
The start-up and shut-down control of portion's condenser 105, and the adjusting to 101 working condition of frequency-changeable compressor.
Specifically, control method includes obtaining the environment temperature of refrigerating device local environment, when environment temperature is less than
Or when being equal to preset upper limit threshold, start side condenser 105, to carry out auxiliary heat dissipation to refrigeration system.It that is to say, bottom
Condenser 103 can synchronize connection when frequency-changeable compressor 101 starts work, to radiate.Side condenser then controlled
Start according to the environment temperature of refrigerating device local environment, only to carry out auxiliary heat dissipation if necessary, guarantees refrigeration system
Stable operation.
In addition, control method further includes setting the limit temperature difference of bottom condenser 103, and obtain bottom condenser temperature
Degree, and judge whether it is higher than environment temperature up to the limit temperature difference.Specifically, the limit temperature difference refers to that bottom condenser 103 is working
What is be able to bear during operation is higher by a certain relatively high temperature gap of environment temperature.When bottom condenser temperature exists
In one preset limit duration persistently be higher than environment temperature reach the limit temperature difference when, illustrate that bottom condenser is in abnormal high temperature at this time
State, heat exchange pressure it is larger, at this time can force start side condenser 105, with to refrigeration system carry out auxiliary heat dissipation, guarantee
The stable operation of bottom condenser 103.
It that is to say, side condenser 105 can start fortune under the control of control method of the invention in both cases
Row.When one is that environment temperature is lower, base portion condenser 103 can effectively drop in 105 starting operations of side condenser at this time
Exchange heat pressure, and it is excessively high not will lead to environment temperature.Secondly when higher for environment temperature, side condenser 105 1 at this time
As not will start operation, but when bottom condenser 103 is also higher at this time, side condenser 105 can controlled starting operation, thus
Guarantee the stable operation of refrigeration system.
It is scattered that control method of the invention allows side condenser 105 to provide additional auxiliary if necessary for refrigeration system
Hot approach makes refrigerating device 1 realize side condenser 105 and bottom condenser 103 while radiating, thus further
Promote the heat exchange efficiency of 1 heat-exchange system of refrigerating device, and control method of the invention also have to bottom condenser 104 and
The security mechanism of entire refrigeration system, can start side condenser in time in the case where 103 abnormal high temperature of bottom condenser
105, avoid refrigeration system from overloading.
In some embodiments of the invention, control method further includes setting the reference current of frequency-changeable compressor 101 and obtaining
Instant electric current when frequency-changeable compressor 101 being taken to run.Further, when instant electric current is more than that reference current is pre- up to preset electric current
When alert threshold value, the revolving speed of frequency-changeable compressor 101 is turned down.
It that is to say, when the heat exchange pressure of condenser especially bottom condenser 103 is excessive, the work of frequency-changeable compressor 101
It is impacted and increase accordingly to make electric current, this can bring security risk to the operation of entire refrigeration system.Control method of the invention
By the way that electric current threshold value of warning is arranged, it is ensured that the normal table of frequency-changeable compressor is run, and prevents refrigeration system from overloading.Further, since
The revolving speed for turning down frequency-changeable compressor 101 advantageously reduces the heat exchange pressure of bottom condenser, and then can shorten side condenser 105
Working time, thus reduce the influence to environment temperature and reduce user and draw due to the contact of the side wall of refrigerating device
A possibility that sense of discomfort risen.
It should be noted that the upper limit threshold for determining side condenser starting service condition may include on unequal first
Multiple numerical value such as threshold value, the second upper limit threshold are limited, and multiple numerical value can be respectively applied to refrigerating device and be in different scattered

Step S212；If it is not, then returning to step S202.
Step S212, control air blower starting operation.
Step S214 judges whether bottom condenser temperature is down to and is differed with environment temperature less than the second difference DELTA T2；If
It is to then follow the steps S216；If it is not, then returning to step S212.
Wherein, the starting operation in step S212 also includes remaining operational under air blower is in operating status.Drum
Blower can be configured to only when the temperature of bottom condenser is greater than environment temperature up to preset first difference DELTA T1When, controlled starting with
Forced heat radiation is carried out to compressor bin.Bottom condenser at this time only cannot effectively radiate under the action of cooling blower, drum
The unlatching of blower can effectively promote high temperature air to accelerate outflow compressor bin, avoid frequency-changeable compressor or condenser because of temperature mistake
It is high and break down.
Further, refrigeration effect, compressor bin needed for the heat exchange efficiency of refrigeration system meets refrigerating device
When interior temperature is relatively low, air blower can be not turned on, and only be radiated by cooling blower to bottom condenser, to save energy
Consumption reduces noise.In addition, for judging the second difference DELTA T of air blower closedown condition2Than the first difference for judging that it is opened
ΔT1Slightly lower 2 DEG C are opened and closed to 4 DEG C to avoid air blower repeatedly.
Referring to Fig. 8, the also controllable air blower pre-cooling of control method is to reinforce imitating refrigerating device ventilation and heat
Fruit.Specifically, it may include following steps:
Step S300 opens the refrigeration system of refrigerating device, and opens forced heat dissipation function.
Step S302 starts compressor.
Step S304, judges whether compressor ran for the first starting time；If so, thening follow the steps S306；If it is not, then
Return to step S302.
Step S306 starts cooling blower.
Step S308, judges whether cooling blower ran for the second starting time；If so, thening follow the steps S310；If
It is no, then return to step S306.
Step S310 starts air blower.
Wherein, if compressor or cooling blower have been in starting operating status, step S302 and step S306 can also be corresponding
Ground includes to remain operational state.Further, the first starting time and the second starting time can be 1min between 3min
Arbitrary value.For example, 1min, 2min or 3min etc..First starting time and the second starting time can be the same or different.
As a result, air blower can the controlled refrigeration system with refrigerating device start, in time be compressor bin into
The compulsory ventilation and heat of row.In this case, compressor, cooling blower air blower can be configured to successively delayed startup, with
Under the premise of guaranteeing result of ventilating heat dissipation, meaningless operation is avoided, reduces energy consumption and noise.
In addition, when refrigerating device stops freezing, air blower can also stop therewith, to reduce energy consumption referring to Fig. 9.
Specifically, it may include following steps:
Step S400 closes refrigeration system.
Step S402, control compressor are out of service.
Step S404, judges whether compressor has shut down the first dwell time；If so, thening follow the steps S406；If it is not,
Then return to step S402.
Step S406, control air blower are out of service.
Step S408, judges whether air blower has shut down the second dwell time；If so, thening follow the steps S410；If it is not,
Then return to step S406.
Step S410, control cooling blower are out of service.
Wherein, if compressor or air blower have been in shutdown status, step S402 and step S406 can also correspondingly include
Remain shut off state.Further, the first dwell time and the second dwell time can be 0.2min to appointing between 0.6min
Meaning value.For example, 0.2min, 0.3min, 0.4min, 0.5min or 0.6min etc..First dwell time and the second dwell time can
It can also be different with identical.
As a result, after compressor stops working, air blower can stop in advance after continuing to blow a short period.Cooling wind
Machine is out of service after can continuing again a short period after air blower stopping.The transverse direction of compressor bin is extended transversely through due to being provided with
The heat (hot-air) that opening, either frequency-changeable compressor or bottom condenser generate is easier to outflow compressor bin.In turn
After frequency-changeable compressor is shut down, the thermal Finite generated in compressor bin only promotes to compress by the cooling blower of cross blowing
Air flowing can meet cooling requirements in cabin, and the air blown directly can distribute outflow from laterally outlet.It is not necessarily to as a result,
Continuous service is approximately perpendicular to the air blower for laterally exporting and blowing outward, can meet the radiating requirements of compressor bin at this time.
If the temperature of compressor bin is not decreased obviously after air blower stops.Air blower can also be according to step S210 to step
The control method of rapid S214 is again started up, to enhance the heat dissipation effect of compressor bin.
