It can be delivered in the freezing chamber through the freezing air duct and blower.
The control method includes the following steps:
Refrigerator starting；
Determine whether the first refrigeration compartment needs to freeze, if so, the a1 that gos to step；If it is not, the b1 that then gos to step；
Above-mentioned steps a1 specifically comprises the following steps:
A11: determine the setting mode of first refrigeration compartment；
Setting mode in first refrigeration compartment includes refrigeration mode and frozen mode, can be according to practical storing
Demand, the setting mode of first refrigeration compartment is adjusted, to meet the storing demand of user.
A12: compressor start, blower starting, air door is opened, blower mask is closed, and the controller control electronics is swollen
The aperture of swollen valve is starting aperture corresponding with the setting mode and the a13 that gos to step；
In step a12 air door open blower mask simultaneously close so that the cooling capacity that generates of evaporator all through blower and
Sub-air channel is transmitted to the first refrigeration chamber, can accelerate the refrigerating efficiency of the first refrigeration compartment.
The starting aperture corresponding when setting mode as refrigeration mode is less than corresponding when setting mode as frozen mode
Start aperture, it is described set mode as refrigeration mode when reduce the flow of the refrigerant, prevent first refrigeration compartment
The phenomenon that being subcooled；It is described set mode as frozen mode when, increase the flow of the refrigerant so that it is described first system
Cold compartment can comparatively fast reach frozen mode.
A13: it is high pre- to determine whether the temperature of first refrigeration compartment reaches shutoff temperature more corresponding than the setting mode
If the temperature of temperature value, if so, controller control electric expansion valve aperture be switched to it is corresponding with the setting mode
Switch aperture and the a14 that gos to step；If it is not, then the controller controls the electric expansion valve holding and the setting mode pair
The starting aperture operation answered is until the temperature of first refrigeration compartment reaches default temperature higher than the shutoff temperature of the setting mode
The temperature of degree value；
The preset temperature numerical value is 2.When it is described set mode as refrigeration mode when, in the compressor start to described
During first refrigeration compartment provides cooling capacity, when the temperature of first refrigeration compartment reaches shutdown more corresponding than refrigeration mode
When the temperature of the high preset temperature numerical value of temperature, because the starting aperture of electric expansion valve is smaller, cause the evaporating temperature of evaporator compared with
It is low, if electronic expansion hair keep starting aperture it is constant, easily lead to the first refrigeration chamber temperature it is too low and first refrigeration between
The problems such as indoor food easily air-dries.
Therefore reach the high preset temperature numerical value of shutoff temperature more corresponding than refrigeration mode in the temperature of first refrigeration compartment
Temperature when, the aperture that the controller controls the electric expansion valve is switched to switching aperture corresponding with refrigeration mode, institute
Corresponding starting aperture is less than the switching corresponding when setting mode as refrigeration mode and opens when stating the mode of setting as refrigeration mode
Degree, that is, increase the aperture of the electric expansion valve, to improve the evaporating temperature of the evaporator, on the one hand, can prevent institute
The case where the first refrigeration compartment is subcooled is stated, the temperature of the first refrigeration compartment is made to reach shutdown corresponding with refrigeration mode as early as possible
Temperature, to reach energy-efficient effect；On the other hand, it can have the function that moisturizing, reinforce the guarantor of first refrigeration compartment
Fresh effect.
When it is described set mode as frozen mode when, the compressor start to first refrigeration compartment provide cooling capacity
During, when the temperature of first refrigeration compartment reaches the high preset temperature numerical value of shutoff temperature more corresponding than frozen mode
When temperature, because the starting aperture of electric expansion valve is larger, cause the evaporating temperature of evaporator higher, if electronic expansion hair keeps opening
Dynamic aperture is constant, and the temperature fluctuation for easily leading to the first refrigeration chamber is larger, and the long period is needed to can be only achieved and frozen mode
Corresponding shutoff temperature causes energy consumption larger.
Therefore reach the temperature of the high preset temperature numerical value of shutoff temperature more corresponding than freezing in the temperature of first refrigeration compartment
When spending, the aperture that the controller controls the electric expansion valve is switched to switching aperture corresponding with frozen mode, described to set
Corresponding starting aperture is greater than the switching aperture corresponding when setting mode as frozen mode when mould-fixed is frozen mode, i.e.,
The aperture of the electric expansion valve is reduced, to reduce the evaporating temperature of the evaporator, on the one hand, reduce first refrigeration
Between indoor temperature fluctuation, so that the temperature of the first refrigeration compartment is reduced to shutoff temperature corresponding with frozen mode as early as possible, thus
Reach energy-efficient effect, and reinforces the reliability of refrigeration system；On the other hand, it can reduce noise.
The switching aperture corresponding when setting mode as refrigeration mode is greater than described when setting mode as frozen mode pairs
The switching aperture answered.
A14: determining whether the temperature of the first refrigeration compartment reaches shutoff temperature corresponding with setting mode, if so,
The compressor shutdown, fan parking, electric expansion valve are closed；If it is not, then compressor continuous service, blower continuous service, institute
It states controller and controls the aperture of the electric expansion valve and corresponding with setting mode switching aperture is kept to run up to described the
The temperature of one refrigeration compartment reaches shutoff temperature corresponding with setting mode.
After the temperature of first refrigeration compartment reaches shutoff temperature corresponding with setting mode, go to step
b1。
Above-mentioned steps b1 specifically comprises the following steps:
B11: determining whether freezing chamber needs to freeze, if so, the starting of the compressor start, blower, blower mask
It opens, air door closing, the controller controls the aperture of the electric expansion valve as freezing starting aperture and gos to step
b12；If it is not, then the compressor, blower remain shut off state, electric expansion valve is remained off；
In step b11 air door close blower mask simultaneously open so that the cooling capacity that generates of evaporator all through blower and
Freezing air duct is transmitted in freezing chamber, can accelerate the refrigerating efficiency of freezing chamber.
The volume of the freezing chamber is less than the volume of first refrigeration compartment, and freezing starting aperture is greater than described the
Corresponding starting aperture when setting mode as refrigeration mode of one refrigeration compartment, while being less than the setting of first refrigeration compartment
Mode corresponding starting aperture when being frozen mode.
If the freezing chamber does not need to freeze, determine whether the first refrigeration compartment needs to freeze again.
B12: determining whether the temperature of freezing chamber reaches the temperature of preset temperature numerical value higher than freezing shutoff temperature, if so,
The aperture that then controller controls the electric expansion valve is switched to freezing switching aperture b13；If it is not, the then controller control
Making the electric expansion valve keeps freezing starting aperture operation until the temperature of the freezing chamber reaches than the freezing shutoff temperature
The temperature of high preset temperature numerical value；
The preset temperature numerical value is 2.During the compressor start provides cooling capacity to the freezing chamber, work as institute
When stating the temperature of temperature arrival preset temperature numerical value higher than freezing shutoff temperature of freezing chamber, because the freezing of electric expansion valve starts
Aperture is larger, causes the evaporating temperature of evaporator higher, if electronic expansion hair keeps freezing, starting aperture is constant, easily leads to freezing
Indoor temperature fluctuation is larger, and the long period is needed to can be only achieved freezing shutoff temperature, causes energy consumption larger.
Therefore when the temperature of the freezing chamber reaches the temperature of preset temperature numerical value higher than freezing shutoff temperature, the control
The aperture that device processed controls the electric expansion valve is switched to freezing switching aperture, and the freezing starting aperture is greater than the freezing and cuts
Aperture is changed, that is, reduces the aperture of the electric expansion valve, to reduce the evaporating temperature of the evaporator, on the one hand, reduces institute
The indoor temperature fluctuation of freezing is stated, the temperature of freezing chamber is made to be reduced to freezing shutoff temperature as early as possible, thus reach energy-efficient effect,
And reinforce the reliability of refrigeration system；On the other hand, it can reduce noise.
The freezing switching aperture is greater than corresponding switching when setting mode as frozen mode of first refrigeration compartment
Aperture, while being less than corresponding switching aperture when setting mode as refrigeration mode of first refrigeration compartment.
B13: determining whether the temperature of freezing chamber reaches freezing shutoff temperature, if so, the compressor shutdown, blower stop
Machine, the electric expansion valve is closed, blower mask is closed；If it is not, then compressor continuous service, blower continuous service, control
The aperture that device controls the electric expansion valve keeps freezing switching aperture operation until the temperature of the freezing chamber reaches freezing and closes
Machine temperature.
After the temperature of the freezing chamber reaches freezing shutoff temperature, determine whether first refrigeration compartment needs again
Refrigeration.
Certainly, it can also first determine whether freezing chamber needs to freeze after refrigerator starting, again when freezing chamber does not need refrigeration
Determine whether first refrigeration compartment needs to freeze.
In conclusion the present invention compressor start to the refrigeration compartment provide cooling capacity during, when the refrigeration
When the temperature of compartment reaches the temperature of the high preset temperature numerical value of shutoff temperature more corresponding than the setting mode, it is swollen to control the electronics
