Abstract
The invention discloses a kind of refrigeration control method of automatically controlled wind cooling refrigerator fault,, according to following situation, refrigeration control is carried out to refrigerator: situation one: when breakdown of refrigerator is communication failure, compressor carries out freezing refrigeration in 20 ± 5 minutes according to operation, run and carry out refrigeration in 20 ± 5 minutes, compressor shutdown 20 ± 5 minutes, and heater does not enter defrost pattern; Situation two: when breakdown of refrigerator is for refrigeration sensor fault or freezing sensor fault, compressor carries out freezing refrigeration in 25 ± 5 minutes according to operation, run after within 20 ± 5 minutes, carrying out refrigeration, compressor shutdown 25 ± 5 minutes, and heater does not enter defrost pattern; Situation three: when breakdown of refrigerator is defrosting sensor fault, then heater initiatively enters defrost pattern and shuts down after running 40 ± 5 minutes.The present invention can make automatically controlled wind cooling refrigerator can normally freeze when failure operation, thus keeps temperature and the refrigeration of room between refrigerator inside.
Description
Technical field
The present invention relates to a kind of refrigeration control method of automatically controlled wind cooling refrigerator fault, belong to the automation control area of automatically controlled wind cooling refrigerator.
Background technology
At present, compressor is there is and quits work in two automatically controlled wind cooling refrigerators when control system fault, refrigerator situation of not freezing is caused to occur, because when temperature sensor (comprising refrigeration sensor, freezing sensor and defrosting sensor) fault or communication failure (inefficacy), refrigerator control system cannot detect refrigerator compartment temperature, thus cause rising or the reduction of uncontrollable indoor temperature, then compressor quits work, refrigerator cannot normally freeze, thus affecting refrigerator normal operation, food cannot be fresh-keeping.
Summary of the invention
The present invention is the weak point for avoiding existing for existing technology, proposes a kind of refrigeration control method of automatically controlled wind cooling refrigerator fault, to make automatically controlled wind cooling refrigerator can normally freeze when failure operation, thus keeps temperature and the refrigeration of room between refrigerator inside.
The present invention is that technical solution problem adopts following technical scheme:
The feature of the refrigeration control method of a kind of automatically controlled wind cooling refrigerator fault of the present invention carries out refrigeration control according to following failure condition to refrigerator:
Situation one: when breakdown of refrigerator is communication failure, compressor carries out loop control in accordance with the following steps to keep refrigeration for refrigerator temperature:
After steps A 1, compressor operating carry out freezing refrigeration in 20 ± 5 minutes, enter steps A 2;
Steps A 2: compressor operating enters steps A 3 after carrying out refrigeration in 20 ± 5 minutes;
Steps A 3: compressor shutdown 20 ± 5 minutes, and heater does not enter defrost pattern;
Situation two: when breakdown of refrigerator is for refrigeration sensor fault or freezing sensor fault, compressor carries out loop control in accordance with the following steps to keep refrigeration for refrigerator temperature:
After steps A 1, compressor operating carry out freezing refrigeration in 25 ± 5 minutes, enter steps A 2;
Steps A 2: compressor operating enters steps A 3 after carrying out refrigeration in 20 ± 5 minutes;
Steps A 3: compressor shutdown 25 ± 5 minutes, and heater does not enter defrost pattern;
Situation three: when breakdown of refrigerator is defrosting sensor fault, then heater initiatively enters defrost pattern and shuts down after running 40 ± 5 minutes.
Compared with the prior art, beneficial effect of the present invention is embodied in:
The present invention is by initiatively setting the method for operation of compressor and heater to overcome the automatically controlled air-cooled product of solution two in process of refrigerastion, when there is communication failure and temperature sensor fault in refrigerator, compressor quits work because temperature being detected the various risks of caused temperature recovery etc., not only can give full play to the effect of refrigeration system, and the dump energy of refrigerator can also be utilized to reach energy-saving effect; Thus ensure refrigeration for refrigerator effect, food and extend freshness.
Accompanying drawing explanation
Fig. 1 is applied environment schematic diagram of the present invention.
Detailed description of the invention
In the present embodiment, a kind of refrigeration control method of automatically controlled wind cooling refrigerator fault is applied in refrigeration system as shown in Figure 1, the composition of refrigeration system comprises: compressor bank, tube connector, anti-condensation pipes, left condenser, right condenser, filter, capillary, refrigerating evaporator, refrigeration and freezing refrigeration all need refrigerating evaporator, the refrigeration control of refrigeration is controlled by the switch of air door, and carries out refrigeration control according to following failure condition to refrigerator:
Situation one: master control borad and display board are adopting in single-wire asynchronous communication process, if display board is in official hour, as do not received the data that master control borad is sent in 20S, then refrigeration system is judged as communication failure; When breakdown of refrigerator is communication failure, compressor carries out loop control in accordance with the following steps to keep the cryogenic temperature that refrigerator is suitable:
After steps A 1, compressor operating carry out freezing refrigeration in 20 ± 5 minutes, enter steps A 2; This running time is fixed according to freezing Homes Using TV time normal, the refrigeration that the maintenance of maximum requirement is freezing;
Steps A 2: compressor operating enters steps A 3 after carrying out refrigeration in 20 ± 5 minutes; The now passive refrigeration of refrigerating evaporator;
Steps A 3: compressor shutdown 20 ± 5 minutes, and heater does not enter defrost pattern; Thus the frost on refrigerating evaporator is removed, for defrost;
Situation two: when the Temperature numerical of A/D module acquires is not in scope, when namely sensor temperature is higher than 70 DEG C or lower than-60 DEG C, refrigeration system is judged as sensor fault; When breakdown of refrigerator is for refrigeration sensor fault or freezing sensor fault, compressor carries out loop control in accordance with the following steps to keep the cryogenic temperature that refrigerator is suitable:
Steps A 1, according to freezing Homes Using TV time normal, compressor operating enters steps A 2 after within 25 ± 5 minutes, carrying out freezing refrigeration;
Steps A 2: according to the Homes Using TV of refrigeration time normal, compressor operating enters steps A 3 after within 20 ± 5 minutes, carrying out refrigeration;
Steps A 3: compressor shutdown 25 ± 5 minutes, and heater does not enter defrost pattern; Thus be refrigerating evaporator defrost
Situation three: when breakdown of refrigerator is defrosting sensor fault, then compressor freezes according to normal control method all the time, and heater initiatively enters defrost pattern and run 40 ± 5 minutes backed off after randoms and shut down, and helps refrigerating evaporator defrost.
Claims (1)
