The control method of confession is applicable to the frequency conversion refrigerator of all capacity (the different model volume such as Liang Men, three or clamshell doors), especially
It just buys back refrigerator suitable for user, first upper electricity or is put into the situation of heat source thermo in refrigerator compartment, and this method can be by
The control device of frequency conversion refrigerator performs.Shown in Figure 1, the control method specifically includes as follows：
Step 110, the temperature information for being presently according to frequency conversion refrigerator environment determine the first operational tapses of compressor.
Specifically, the temperature information that frequency conversion refrigerator is presently in environment can be detected by temperature sensor.
Generally, the mode of operation of frequency conversion refrigerator can be divided into intelligent mode and manual adjustment mode, wherein, intelligent mode refers to
Environment temperature of the master control borad of refrigerator according to residing for refrigerator automatically adjusts the operational tapses of compressor；Manual adjustment mode refers to user
According to the temperature of the demands of individuals of oneself, manually setting refrigerator compartment, the temperature adjustment compressor that master control borad is set according to user
Operational tapses.The operational tapses of compressor generally include 1-7 shelves, the specific ambient temperature range of each grade of correspondence and compression
Machine rotating speed, such as when environment temperature is less than 14 degrees Celsius, compressor is usually operated at 1 gear, and corresponding rotating speed is 2400r/
min；With the rise of environment temperature, the operation range of compressor also raises, and corresponding rotating speed also accordingly increases, and concrete numerical value can
To be set by developer.
It can be seen that when refrigerator work is in intelligent mode, master control borad adjusts compression according only to the environment temperature residing for refrigerator
The operational tapses of machine, now, if the higher food of temperature is put into refrigerator compartment by user, the temperature of refrigerator compartment will certainly be caused
Rise suddenly, but the environment temperature residing for refrigerator can't be put into high-temperature food because of refrigerator compartment and change,
Therefore the operational tapses that still can be determined according to existing control method, compressor with the environment temperature being presently according to refrigerator
Continue to run with, can't suddenly be raised because of the temperature of refrigerator compartment and increase the operational tapses of compressor, therefore, refrigerator compartment

On the other hand, if refrigerator is new fridge, user has just been bought back home after first upper electricity, or refrigerator power-off for a long time on again
The temperature of refrigerator compartment is of a relatively high when electricity, and the environment temperature being presently in according only to refrigerator determines compressor operating
The control method of gear is again such that the cooling rate of refrigerator compartment is relatively slow, and the available machine time of compressor extends, power consumption
Become big.
Further, for air-cooled variable frequency refrigerator, pressure is determined in the temperature information that environment is presently according to frequency conversion refrigerator
Also include while first operational tapses of contracting machine：Determine the operational tapses of fan electromotor.

During machine is run with first operational tapses, the temperature of refrigerator compartment is detected, when the compartment temperature is more than given threshold,
The operational tapses of compressor are then further adjusted on the basis of first operational tapses.Generally, compressor is with according to environment
The time for the gear operation that temperature determines is more than 20 minutes, until refrigerator compartment internal temperature reaches the temperature of compressor shutdown
Degree, compressor are out of service.
For example, the environment temperature that refrigerator is presently in is 10 degrees Celsius, the compressor that master control borad determines according to the temperature is transported
Row gear is 1 grade, and compressor starts are run with rotating speed corresponding to 1 grade, and now refrigerator compartment temperature is detected, if detecting
Compartment temperature be more than given threshold, then illustrate refrigerator compartment temperature it is of a relatively high, it is necessary to further increase compressor operation
Gear, such as the operational tapses of compressor can directly be adjusted and arrive highest gear, so that compressor realizes maximum refrigerating capacity,
Reach the quick purpose for reducing refrigerator compartment temperature.
Step 130, when the compartment temperature is more than given threshold, adjust the operational tapses of the compressor.
Specifically, whether need the decision condition of the further operational tapses of regulation compressor except the " compartment temperature
More than given threshold " outside, it can also be that " difference between the observed temperature of refrigerator compartment and the design temperature of compartment is more than pre-
If the frequency conversion temperature difference ".
Exemplarily, when the compartment temperature is more than given threshold, the operational tapses of the compressor are adjusted, including：
When the compartment temperature is more than given threshold, the operational tapses of the compressor are controlled to be replaced by the second operation shelves
Position；
Wherein, compressor rotary speed corresponding to second operational tapses is higher than compressor corresponding to first operational tapses
Rotating speed；Preferably, second operational tapses can be the highest operational tapses of compressor, to realize most fast refrigerating speed；
If considering problems of energy consumption, corresponding compressor operating can be further selected according to the actual temp numerical value of refrigerator compartment
Gear, to realize the balance of refrigerating speed and energy resource consumption.
Further, if the refrigerator is air-cooled variable frequency refrigerator, when the compartment temperature is more than given threshold, institute is adjusted
The operational tapses of fan electromotor are correspondingly adjusted while stating the operational tapses of compressor.
A kind of control method for frequency conversion refrigerator that the present embodiment provides, the temperature of environment is presently according to frequency conversion refrigerator first
