Technical field
The invention belongs to the technical field of refrigerator, particularly a kind of control method being suitable for the refrigerator of hot environment.
Background technology
In the modern life, the instructions for use of consumer to refrigerator is more and more higher on the one hand, and the environment for use of another aspect refrigerator and service condition are also more and more towards development in pluralism.This requires that refrigerator not only can normally can use under common normal condition, and also normally should be able to run use under harsh condition.Such as under hot environment (high-load condition), in the situations such as voltage pulsation is abnormal.And often under above-mentioned rigor condition, the load of refrigerator system can exceed the normal tolerance range of compressor and cause start-up and operation fault and instability, thus refrigerator is caused normally not use.Certainly for solving the problem, when designing, compressor coupling can be strengthened, but this not only can cause the rising of cost, and the waste of energy when can cause using under normal operation.
Although there is various controlling method for refrigerator in prior art, but the good method of neither one solves refrigerator reduction system particularly compressor load peak value in high load capacity startup situation, thus the control method of the system of guarantee particularly compressor start and runnability.
Chinese patent CN1414327 discloses a kind of control method of multi-chamber refrigerator.The advantage of the method is first to open needs the valve in the refrigerating circuit of refrigeration compartment to open compressor cooling again, and compressor stop after open all valves with the pressure of balanced system cold loop, but do not embody each room stagger refrigeration with the method reducing system loading peak value.
Summary of the invention
The problem to be solved in the present invention provides a kind of control method being suitable for the refrigerator of hot environment.The method takes delay Optimization to control under high-load condition, is staggered by freezing and refrigeration load peak, thus reduces the total load peak of system, ensures the normal start-up and operation of compressor.Do not increase cost and not under using the prerequisite that impacts under normal condition, solve the start-up and functionning problem of refrigerator under hot environment and high-load condition.
For solving the problems of the technologies described above, technical scheme of the present invention is:
The invention provides a kind of control method being suitable for the refrigerator of hot environment, described refrigerator comprises refrigerating chamber and refrigerating chamber, is provided with compressor, fan and cryogenic temperature sensor in refrigerating chamber; Be provided with refrigerated storage temperature sensor in refrigerating chamber, be provided with air door in the air channel between refrigerating chamber and refrigerating chamber, compressor, fan, air door, cryogenic temperature sensor, refrigerated storage temperature sensor are all connected with the control panel set by refrigerator; The control method of described refrigerator is: the cryogenic temperature Tf that control panel detects according to cryogenic temperature sensor selects the control model of refrigerator to be general mode or first delay Optimization pattern, then proceeds to general mode.
In such scheme, as cryogenic temperature Tf < t1, the control model of refrigerator is general mode; Wherein, t1 is constant.
In such scheme, as cryogenic temperature Tf >=t1, the control model of refrigerator is first delay Optimization pattern, then proceeds to general mode; Wherein, t1 is constant.
In such scheme, described general mode is:
As cryogenic temperature Tf >=Tfin, compressor, fan are opened, until Tf≤Tfout; If now refrigerated storage temperature Tr >=Trin, then compressor, fan unlatching, door opening, until Tr≤Trout;
As Tf < Tfin, compressor cuts out, if now refrigerated storage temperature Tr >=Trin, fan and door opening, until Tr≤Trout;
Wherein, Tfin is freezing turn-on temperature; Trin is refrigeration turn-on temperature; Tfout is freezing shutoff temperature; Trout is refrigeration shutoff temperature.
Preferably, described t1 is 38 DEG C.
In such scheme, described delay Optimization pattern is:
Compressor, fan are first opened, until during cryogenic temperature Tf≤t2, then enter general mode; Wherein, t2 is constant, and t1 > t2.
Preferably, described t2 is 10 DEG C.
To sum up, Tfin, Tfout are relevant with freezing design temperature, the switching on and shutting down temperature that different design temperatures is corresponding different, Tfin > Tfout; Trin, Trout are relevant with refrigeration design temperature, the switching on and shutting down temperature that different design temperatures is corresponding different, Trin > Trout; Because the design temperature of refrigeration is greater than freezing design temperature, certainly so Trin > Trout > Tfin > Tfout; T1 > t2 > Trin > Trout > Tfin > Tfout.
Compared with prior art, the present invention has following beneficial effect:
The present invention selects the control model of refrigerator according to the cryogenic temperature Tf that cryogenic temperature sensor detects, under hot environment and high-load condition, take delay Optimization to control, freezing and refrigeration load peak is staggered, thus reduces the total load peak of system, to ensure the normal start-up and operation of compressor.In addition, do not increase cost and not under using the prerequisite that impacts under normal condition, solving the start-up and functionning problem of refrigerator under high ambient conditions, thus improve the stability and reliability that refrigerator uses.

Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, the present invention is described in detail.
Fig. 1, refrigerator of the present invention comprises refrigerating chamber 6 and refrigerating chamber 7, is provided with compressor 1, fan 3 and cryogenic temperature sensor 2 in refrigerating chamber 7; Be provided with refrigerated storage temperature sensor 5 in refrigerating chamber 6, be provided with air door 4 in the air channel between refrigerating chamber and refrigerating chamber, compressor 1, fan 3, air door 4, cryogenic temperature sensor 2 are all connected with the control panel set by refrigerator with refrigerated storage temperature sensor 5, as shown in Figure 2.
The control method of refrigerator of the present invention is:
Control panel selects the control model of refrigerator to be general mode or first delay Optimization pattern by the cryogenic temperature Tf detected cryogenic temperature sensor 2, then proceeds to general mode, as shown in Figure 3.
If when cryogenic temperature sensor 2 detects cryogenic temperature Tf < t1, refrigerator enters general mode and controls; T1 value is 38 DEG C.
