It is cold；Finally, returning compressor compresses after refrigerant evaporation into high temperature and high pressure gas, so progress circularly cooling.
Based on above-mentioned refrigerator, the embodiment of the present invention provides a kind of control method of refrigerator, as shown in figure 4, including such as
Lower step:
101, turn-on temperature Trk is refrigerated when the temperature Tr for detecting refrigerator room is more than or equal to, or detects freezer
When the temperature Tf of room is more than or equal to freezing turn-on temperature Tfk, compressor start is controlled.
102, when the temperature Tr for detecting refrigerator room is less than or equal to refrigeration shutdown temperature Trt, and freezer is detected
When the temperature Tf of room is less than or equal to freezing shutdown temperature Tft, compressor shutdown is controlled.
103, after compressor start, when the temperature Tr for detecting refrigerator room is more than or equal to refrigeration turn-on temperature Trk,
Control refrigeration blower booting；When the temperature Tr for detecting refrigerator room is less than or equal to refrigeration shutdown temperature Trt, control refrigeration blower
Shutdown.
104, after compressor start, control freezing blower booting, when detecting that the temperature Tf of freezing compartment is less than or equal to
When freezing shutdown temperature Tft, control freezing blower shutdown.
It should be noted that refrigeration turn-on temperature Trk is greater than refrigeration shutdown temperature Trt, and it is big to freeze turn-on temperature Tfk
In freezing shutdown temperature Tft.Wherein, temperature sensor has can be set in each compartment of refrigerator, for detecting the temperature of refrigerator room
Spend the temperature Tf of Tr, freezing compartment.Above-mentioned 101,102,103,104 do not limit sequencing, it is to be understood that 103 with
104 can carry out simultaneously or both in any first carry out.
In addition, under compressor shutdown state, to guarantee that the cooling capacity of refrigeration evaporator makes full use of.This method further include:
Under compressor shutdown state, shutdown temperature Trt is refrigerated when the temperature Tr for detecting refrigerator room is more than or equal to, and refrigerate steaming
When sending out the temperature Tvr of device less than or equal to the first preset temperature, the refrigeration blower booting is controlled, first preset temperature is less than
Equal to zero degree.Under compressor shutdown state, when detect refrigerator room temperature Tr be less than or equal to refrigeration shutdown temperature Trt or
When person detects that the temperature Tvr of refrigeration evaporator is greater than the second preset temperature, the refrigeration blower shutdown is controlled, described first is pre-
If temperature is greater than zero degree.Wherein the temperature Tvr of refrigeration evaporator can be using the temperature sensor being arranged on refrigeration evaporator
Acquisition.
Specifically, referring to the operating parameter curve of Fig. 5 refrigerator provided, temperature, freezer including refrigerator room
Temperature, the temperature of refrigeration evaporator, the temperature of refrigerating evaporator and the compressor effective power of room, to above-mentioned control method
Be described as follows: the temperature Tr of refrigerator room reaches the temperature of refrigeration turn-on temperature Trk (Tr >=Trk) or freezing compartment
Tf reaches freezing turn-on temperature Tfk (Tf >=Tfk), and (t1 moment) refrigerator needs to freeze at this time, control compressor is opened, and refrigeration is steamed
Device and the decline of refrigerating evaporator temperature are sent out, while refrigerating blower, freezing blower booting.It should be noted that by refrigeration blower
The influence of booting, refrigerating evaporator temperature can relatively high when fan parking (comparison refrigeration), but due to the steaming of refrigerating evaporator
It is lower than freezing compartment temperature to send out temperature, therefore can freeze for freezing compartment, refrigerator room is completed after refrigeration (i.e. Tr≤Trt),
It refrigerates fan parking (t2 moment), since system needs to rebalance after refrigeration fan parking, freezing and evaporating temperature can be fast at this time
Speed decline, the temperature of freezing compartment can quickly be pulled to break point (t3 moment) (i.e. Tf≤Tft), when refrigerator room and freezer
After the temperature of room reaches break point, compressor shutdown；After compressor shutdown, refrigeration evaporator, refrigerating evaporator temperature rise,
Refrigeration evaporating temperature is lower when due to shutting down, as long as refrigerator room temperature is higher than break point (Tr is greater than Trt), refrigeration is steamed
The temperature for sending out device (can acquire) Trv≤0 DEG C by the temperature sensor being arranged on refrigeration evaporator, then control refrigeration blower and open
It opens, refrigeration evaporator residue cooling capacity can be taken out of, be refrigeration chamber, simultaneously because refrigerating chamber return air temperature is high, with stopping
The increase refrigeration evaporator temperature of machine time and blower opening time can rise to 0 DEG C or more (t4-t5 moment in such as Fig. 5), real
Existing refrigeration evaporator defrosting；Under compressor shutdown state, when the temperature Tr of refrigerator room is less than or equal to refrigeration shutdown temperature Trt
Or at 0 DEG C of the temperature Tvr > of refrigeration evaporator, control refrigeration blower shutdown.The temperature of compartment to be refrigerated rises to refrigeration booting
After temperature (Tr >=Trk) or the temperature of freezing compartment rise to freezing turn-on temperature (Tf >=Tfk), compressor is again turned on refrigeration,
So circulation.In conclusion refrigeration air-blower control is as follows: under compressor open state, Tr >=Trk, refrigeration blower booting, Tr≤
Trt refrigerates fan parking；Under compressor shutdown state, Tr > Trt and Tvr≤0 DEG C, refrigeration blower are switched on, Tr≤Trt or Tvr
>=2 DEG C (to prevent evaporator temperature from overheating, fan operation keeps refrigerator room temperature recovery too fast), refrigerate fan parking.
It should be noted that being to complete Tr≤Trt after refrigeration first with refrigerator room above, refrigeration blower first shuts down progress
Illustrate, if the temperature of freezing compartment first reaches shutdown temperature, referring to shown in Fig. 6, the temperature of freezing compartment reaches freezing and shuts down
(t2 moment) freezing blower stalling after temperature, refrigerator room also needs to freeze at this time, if freezing fan parking, refrigerator overall thermal are negative
Lotus reduces (decline of t2-t3 moment compressor effective power), and the freezing blower of freezing compartment can not be by freezing compartment's thermic load band
Forced heat-exchanging is carried out to refrigerating evaporator, so freezing chamber evaporator temperature can draw very low, referring to shown in Fig. 6, compressor is effective
Power will be greatly reduced, and cause refrigeration for refrigerator inefficiency, to avoid the above problem, (the t1-t3 moment after compressor start
Section), when detect freezing compartment temperature Tf be less than or equal to freezing shutdown temperature Tft when, and refrigerate blower shutdown after, control
The shutdown of fine frozen blower.I.e. in the moment section t1-t3, control freezing blower is in normal open state, even if detecting freezer
The temperature Tf of room is less than or equal to freezing shutdown temperature Tft, still in refrigeration blower shutdown (t3 after i.e. refrigerator room is freezed
Moment) after, then to freezing blower shutdown, to improve the refrigerating efficiency of refrigerator.
