With the startup-shutdown period residing for compressor, the startup-shutdown period according to residing for ambient temperature and compressor determines compressor
The calculation of frequency, according to identified calculation calculate compressor running frequency, so as to get compressor operating frequency
Rate more accurate.
Due to refrigerator power on or defrost after, refrigerator load increase, fast cooling is needed to reach the refrigeration demand of refrigerator, because
This on the compressor electricity or defrost after first time booting operation can have from the running frequency of compressor in subsequent process it is different
Calculation, with ensure power on or defrost after can be rapidly achieved the refrigeration demand of refrigerator after, according to practical operation situation to pressure

When the first time booting after electricity or after defrost is run on the compressor, the refrigeration that fast cooling reaches refrigerator is needed to need
It asks, because ambient temperature directly affects the heat exchange efficiency of compressor, therefore directly can determine to press according to ambient temperature
The calculation of contracting machine running frequency to ensure to obtain higher heat exchange efficiency, ensures fast cooling demand.It specifically, can be pre-
The calculation of ambient temperature and its corresponding compressor operating frequency is first formulated, in order to enable the frequency arrived is more

Wherein, specific calculation formula can be according to said external environment temperature, the first continuous service frequency of plasticator,
The different correspondences of one user setting temperature and compressor low-limit frequency are fitted determining.It should be noted that in addition to
Outside above-mentioned parameter, the running frequency of compressor can be also calculated by other refrigerator actual operation parameters, can be according to specific
Demand is configured, and this will not be repeated here.
Specifically, as shown in figure 4, when the compressor whether booting operation for the first time after the power is turned on or after defrost when, it is described
The calculation of the compressor operating frequency is determined according to the ambient temperature, and according to identified calculation meter
The step of running frequency for calculating the compressor, includes：
Step S221, judges whether the ambient temperature is more than predetermined threshold value；
If so, step S2211 is performed, if it is not, then performing step S2212.
Step S2211 calculates the running frequency of the compressor according to the highest frequency of the compressor；
Step S2212 calculates the compressor according to the low-limit frequency of the compressor and the ambient temperature
Frequency.
When ambient temperature is more than predetermined threshold value, it is believed that the heat exchange efficiency of refrigerator is relatively low at this time, can be according to compression
The highest frequency of machine calculates the running frequency of compressor, and different most high frequencies is specifically being set according to different ambient temperatures
Rate adjusting parameter, highest frequency after being adjusted using adjusting parameter as the running frequency of compressor, make compressor can be at compared with
High running frequency realizes the fast-refrigerating of refrigerator.It should be noted that compressor operating frequency at this time should be with external rings
The raising of border temperature and increase specific.It specifically, can be when ambient temperature be more than predetermined threshold value, directly by compressor
Frequency of the highest frequency as compressor accelerates refrigerating speed, refrigerator is enable quickly to meet user demand.Wherein, predetermined threshold value
It can be configured according to actual demand.
In addition, when ambient temperature is less than or equal to predetermined threshold value, it is believed that refrigerator has preferable heat exchange effect at this time
Rate can be calculated the running frequency of compressor by the low-limit frequency and ambient temperature of compressor, ensure refrigerating speed
The frequency of compressor can be optimized simultaneously, improve the energy consumption of refrigerator, avoid waste and the noise of the energy.It specifically, can
Determine to be adapted to the frequency increment of environment nowadays temperature by ambient temperature, increase on the basis of low-limit frequency on
It states frequency increment and obtains the running frequency of compressor, to realize the optimization to compressor operating frequency.
Further, as shown in figure 5, the controlling method for refrigerator further includes：
Step S50, after detecting the refrigerator and being acted there are the switch gate, default compressor startup-shutdown period
It is interior, obtain the first compartment temperature of the refrigerator and the first shutdown temperature of the compressor；
Step S60, judges whether first compartment temperature and first shutdown temperature meet frequency modulation requirement；
If satisfied, then perform step S61, if being unsatisfactory for or the startup-shutdown period of compressor is more than and presets each compressor start-stop
During the machine period, then step S62 is performed.
Step S61 determines the operation frequency of the compressor according to first compartment temperature and first shutdown temperature
Rate；
Step S62 performs the startup-shutdown according to residing for the ambient temperature of the refrigerator and the compressor
Period determines the calculation of the compressor operating frequency, and institute is calculated according to identified compressor operating frequency calculation
The step of stating the running frequency of compressor.
The concrete numerical value in default compressor startup-shutdown period can be configured according to actual conditions.After switch gate action
A default compressor startup-shutdown period, it is believed that the operation of refrigerator is affected by switch gate action at this time.First compartment
Temperature can be specially the temperature for characterizing refrigerator inside, can be specially the temperature of refrigerating chamber, the temperature of refrigerating chamber or according to freezing
Temperature that the temperature of room and the temperature of refrigerating chamber obtain etc..First shutdown temperature can be specially the set temperature or compressor of user
It is adapted to the arrange parameter of user and determining shutdown temperature.
Within default compressor startup-shutdown period, judge that compressor is according to the first compartment temperature and the first shutdown temperature
The no frequency modulation demand for meeting compressor, frequency modulation demand can be configured according to actual conditions, can specifically pass through the first compartment temperature
As soon as the temperature difference limit value with the first shutdown temperature meets frequency modulation demand more than this limit value, no more than limit value then not
Meet frequency modulation demand.Meet frequency modulation demand and then show that current frequency is unsatisfactory for the operating status of current refrigerator, then it can be according to
Frequency is adjusted in one compartment temperature and the first shutdown temperature；It, can be according to ambient temperature if being unsatisfactory for frequency modulation demand
Corresponding compressor operating frequency is determined with the startup-shutdown period residing for compressor.
By the above-mentioned means, make refrigerator can be there are determine to meet current refrigerator operating status when switch gate action
Frequency values improve the Energy Efficiency Ratio of refrigerator.
Specifically, as shown in fig. 6, described judge whether first compartment temperature and first shutdown temperature meet
The step of frequency modulation requires includes：
Step S601 determines corresponding first fiducial temperature threshold value according to the ambient temperature, calculates described first
First temperature difference of compartment temperature and first shutdown temperature；
Step S602, judges whether first temperature difference is greater than or equal to frequency modulation temperature threshold；
If so, perform step S63；If it is not, then perform step S64.
Step S603 judges that first compartment temperature and first shutdown temperature meet the frequency modulation requirement；
Step S604 judges that first compartment temperature and first shutdown temperature are unsatisfactory for the frequency modulation requirement.
Frequency modulation temperature difference threshold is used to judge whether the first compartment temperature and the first shutdown temperature meet frequency modulation requirement.In order to suitable
Should be in more complicated refrigerator operating status, different ambient temperatures can correspond to different frequency modulation temperature difference thresholds, when the first temperature
Difference meets frequency modulation demand when being greater than or equal to frequency modulation temperature difference threshold, is unsatisfactory for when the first temperature difference is less than frequency modulation temperature difference threshold
Frequency modulation demand.
Specifically, the as shown in fig. 7, compressor according to first compartment temperature and first shutdown temperature
Running frequency the step of include：
Step S611 determines corresponding frequency according to the frequency modulation temperature range where first temperature difference；
Step S612, using the corresponding frequency as the running frequency of the compressor.
When the first temperature difference is more than frequency modulation temperature difference threshold, in order to be adapted to more complicated refrigerator operating status, to determine
More accurately compressor operating frequency, the temperature range that can will be greater than frequency modulation temperature difference threshold in advance are divided into several sections, often
A section corresponds to the calculation of a compressor operating frequency or compressor operating frequency.According to the temperature where the first temperature difference
Poor section can determine the compressor operating frequency for meeting current refrigerator operating status.
Further, it is described within default compressor startup-shutdown period, obtain the first compartment temperature of the refrigerator with
And the compressor the first shutdown temperature the step of before, further include：
After detecting the refrigerator and being acted there are the switch gate, judge whether the duration of the switch gate action is big
In or equal to the first preset time；
If so, described in performing within default compressor startup-shutdown period, the first compartment temperature of the refrigerator is obtained
And the compressor the first shutdown temperature the step of.
Compressor is just redefined according to aforesaid way when switch gate duration reaches the first preset time
If frequency switch gate duration is less than the first preset time, it is believed that the influence very little that switch gate loads refrigerator, it can
Compressor is controlled to continue to run with existing frequency.By the above-mentioned means, it can ensure that running frequency adapts to current refrigerator operation shape
Ensure the stability of compressor operating while state.
Further, as shown in figure 8, above-mentioned controlling method for refrigerator further includes：
Step S70, when the compressor is not at after the power is turned on or defrost after is switched on the operation phase, and the outside for the first time
When environment temperature is more than predetermined threshold value, the second frequency that the compressor continuous service is more than the second preset time is obtained；
Step S80 improves the second frequency according to default adjusting parameter；
Step S90, using the second frequency after the raising as the running frequency of the compressor.
When the compressor is not at after the power is turned on or defrost after is switched on the operation phase, and the ambient temperature for the first time
During more than predetermined threshold value, the heat exchange efficiency of compressor is relatively low at this time, if compressor continuous service is more than the second preset time at this time,
Show that this compressor frequency is unsatisfactory for current heat exchange demand, then need to improve second frequency, control pressure according to default adjusting parameter
Contracting machine is run according to the second frequency after raising, to ensure the refrigeration demand of refrigerator.Also, when compressor is switched on next time,
It is run according to the second frequency after raising.Wherein, the second preset time can be set according to practical condition.It should be noted that
Second frequency maximum after raising is no more than the highest frequency of compressor.
Specifically, adjusting parameter, which can be a pre-set frequency, adjusts amplitude, added on the basis of second frequency
Frequency adjustment amplitude obtains the frequency of compressor；Can also be that different raisings are corresponded to according to the section where second frequency size
Frequency adjusted value afterwards；Can also be with the adjustment numerical value corresponding to refrigerator current operating parameter, such as continued according to compressor
Run time, user setting temperature etc. are to the adjustment numerical value that should determine that.
For example, the running frequency of compressor can will be divided into several when ambient temperature is more than predetermined threshold value
Gear judges the gear where current compression unit frequency, is getting frequency of the compressor continuous service more than the second preset time
During rate, control compressor operating frequency improves one grade of operation.
If it should be noted that not getting the second frequency that continuous service is more than the second preset time, can control
Compressor continuation is run with current frequency or the running frequency according to the appropriate reduction compressor of other rules.
It by the above-mentioned means, can be when ambient temperature be more than predetermined threshold value, according to current compressor heat exchange state
The frequency of compressor is adjusted, ensures the adjusting for making the being adapted to property of frequency of compressor while refrigerator heat exchange efficiency.
Further, it is described to obtain step of the compressor continuous working period more than the second frequency of the second preset time
Suddenly include：
Every preset time period, the second frequency is obtained in the preset time period.
It is not at being switched on for the first time the operation phase after the power is turned on or after defrost, and the ambient temperature in the compressor
During more than predetermined threshold value, every 1 hour, second frequency of the compressor continuous working period more than 30 minutes is obtained within this hour
Rate.
By the above-mentioned means, recyclable compressor operating frequency when being more than predetermined threshold value to ambient temperature carries out
Adjustment, improve determining frequency accuracy.
