When degree reaches compressor opening temperature, control compressor start, and control solenoid valve, make refrigerant sequentially enter freezing capillary with
And refrigerating evaporator, control freezing blower are run with the second rated speed, make freezing compartment by normal refrigeration；Blower is refrigerated with the
Stop after the 50%-80% operation setting time of one rated speed, wherein first rated speed is the minimum air quantity of refrigerator room
Revolving speed under recycle ratio；Second rated speed is the revolving speed under the minimum air quantity recycle ratio of freezing compartment.For refrigerator room
For, it can not be utilized if directly stopping refrigeration blower and will lead to remaining cooling capacity on refrigeration evaporator, surface frost layer is with operation
The lengthening of time is more and more thicker, leads to refrigerating efficiency worse and worse, and power consumption increases；Therefore, it need to be refrigerated while freezing refrigeration
Blower continues to run a period of time, makes the cross-ventilation of evaporator residue cooling capacity and refrigerator room for a period of time, and refrigerates at this time
Blower is run with the 50%-80% of the first rated speed can avoid wind speed excessively high the problem of causing noise and energy consumption to increase.
Specifically, the control refrigeration blower run with the 50%-80% of the first rated speed stop after setting time include,
After the refrigeration blower is with the 50%-80% operation of the first rated speed, the temperature of the refrigeration evaporator is detected, when described
When refrigeration evaporator temperature is greater than 2-8 DEG C, controls the refrigeration blower and stop.When refrigeration evaporator is greater than 2-8 DEG C, surface frost layer
It can melt, stopping blower at this time then reduces noise of refrigerator, and energy consumption reduces.
Obviously, the above embodiments are merely examples for clarifying the description, and does not limit the embodiments.It is right
For those of ordinary skill in the art, can also make on the basis of the above description it is other it is various forms of variation or
It changes.There is no necessity and possibility to exhaust all the enbodiments.And it is extended from this it is obvious variation or
It changes still within the protection scope of the invention.
