It senses the temperature of the regenerator and feeds back to the controller, the controller is in first temperature sensor received
When the temperature sensed is less than or equal to the phase transition temperature of the cold-storage material, the compressor shutdown, while the blower are controlled
Starting, air door, which are opened, is supplied to the refrigeration compartment with the cooling capacity for accumulating the regenerator, can reach fresh-keeping and prevent
The effect of frostbite food.
Further, the temperature of regenerator is less than or equal to the phase transition temperature of the cold-storage material in step a22 ', and blower opens
After dynamic, air door opening and the compressor are in shutdown status, the control method further includes following steps:
A23 ': the temperature that the controller is sensed according to second temperature sensor determines whether refrigeration compartment reaches refrigeration and close
Machine point if so, the fan parking, air door are closed, and determines the setting mode of refrigeration compartment again；If it is not, then blower is protected
Operating status, and return step a21 ' are held, i.e., described first temperature sensor continues to sense the temperature of regenerator.
The cooling capacity that the regenerator is accumulated is conveyed to the refrigeration compartment that is, opening in the fan operation, air door
In the process, first temperature sensor senses the temperature of the regenerator in real time, to be higher than institute in the temperature of the regenerator
When stating the phase transition temperature of cold-storage material, controls the air door and be in close state, while the compressor, blower start to the storage
Cooler provides cooling capacity, to guarantee that the temperature of the regenerator is not higher than institute during the fan operation, air door are opened
Phase transition temperature is stated, to reinforce refrigeration effect.
The control method of refrigerator in the control method and first embodiment of refrigerator in second embodiment of the invention
In addition to above-mentioned difference, other are all the same, repeat no more in this.
In conclusion refrigerator of the invention is by being arranged close to the evaporator or the cold-storage in the air duct
Device, after the refrigeration compartment is converted to refrigeration mode, compressor start provides cooling capacity and regenerator between refrigeration to regenerator
Room provides cooling capacity alternately, i.e., is delivered to refrigeration compartment by the cooling capacity that regenerator is accumulated and the refrigeration compartment exchanges heat, and
The cooling capacity that compressor start finisher generates is not fed directly to refrigeration chamber, because that without frostbite food and can reach
Fresh-keeping effect.
