Abstract
The invention discloses a refrigeration control method for an electric control air cooling refrigerator fault. The refrigeration control method is characterized in that refrigeration control is carried out on a refrigerator according to the following fault conditions: (1) when a communication fault of the refrigerator occurs, a compressor carries out freezing refrigeration for 20+/- 5 minutes and carries out cold storage refrigeration for 20+/- 5 minutes, then the compressor is off work for 20+/-5 minutes and a heater does not start a defrosting mode, and the preceding steps are repeatedly circulated; (2) when the refrigerator fault is that a cold storage sensor breaks down or a freezing sensor breaks down, the compressor carries out freezing refrigeration for 25+/-5 minutes and carries out cold storage refrigeration for 20+/-5 minutes, then the compressor is off work for 25+/- 5 minutes and the heater does not start a defrosting mode, and the preceding steps are repeatedly circulated; (3) when the refrigerator fault is that a defrosting sensor breaks down, the heater actively starts a defrosting mode and is shut down after 40+/-5 minutes. According to the refrigeration control method, when the electric control air cooling refrigerator operates in a fault state, normal refrigerating can be carried out, and the temperature and the refrigerating effect of an internal chamber of the refrigerator are maintained.
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, two automatically controlled wind cooling refrigerators exist compressor to quit work when control system fault, cause not refrigeration situation generation of refrigerator, 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, thereby cause rising or the reduction of uncontrollable indoor temperature, compressor quits work, refrigerator cannot normally freeze, thereby affect refrigerator, normally run, food cannot be fresh-keeping.
Summary of the invention
The present invention is for avoiding the existing weak point of existing technology, proposes a kind of refrigeration control method of automatically controlled wind cooling refrigerator fault, so that automatically controlled wind cooling refrigerator can normally freeze when failure operation, thereby keeps temperature and the refrigeration of chamber 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 is, according to following failure condition, refrigerator is carried out to refrigeration control:
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:
Steps A 1, compressor operating carry out, after freezing refrigeration, entering steps A 2 for 20 ± 5 minutes;
Steps A 2: compressor operating carries out, after refrigeration, entering steps A 3 for 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 refrigeration sensor fault or freezing sensor fault, compressor carries out loop control in accordance with the following steps to keep refrigeration for refrigerator temperature:
Steps A 1, compressor operating carry out, after freezing refrigeration, entering steps A 2 for 25 ± 5 minutes;
Steps A 2: compressor operating carries out, after refrigeration, entering steps A 3 for 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, heater is shut down after initiatively entering defrost pattern and moving 40 ± 5 minutes.
Compared with the prior art, beneficial effect of the present invention is embodied in:
The present invention solves two automatically controlled air-cooled products by initiatively setting the method for operation of compressor and heater in process of refrigerastion to overcome, while there is communication failure and temperature sensor fault in refrigerator, compressor is because the quit work various risks of caused temperature recovery etc. of temperature being detected, not only can give full play to the effect of refrigeration system, and can also utilize the dump energy of refrigerator to reach energy-saving effect; Thereby guarantee refrigeration for refrigerator effect, food and extend freshness.
Accompanying drawing explanation
Fig. 1 is applied environment schematic diagram of the present invention.
The specific embodiment
In the present embodiment, a kind of refrigeration control method of automatically controlled wind cooling refrigerator fault is in the refrigeration system being applied in 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 according to following failure condition, refrigerator is carried out to refrigeration control:
Situation one: master control borad and display board in adopting single-wire asynchronous communication process, if display board in official hour, the data of sending as do not received master control borad in 20S, 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 suitable cryogenic temperature of refrigerator:
Steps A 1, compressor operating carry out, after freezing refrigeration, entering steps A 2 for 20 ± 5 minutes; Be freezing Homes Using TV when normal and fixed this running time, the maximum freezing refrigeration of maintenance requiring;
Steps A 2: compressor operating carries out, after refrigeration, entering steps A 3 for 20 ± 5 minutes; The passive refrigeration of refrigerating evaporator now;
Steps A 3: compressor shutdown 20 ± 5 minutes, and heater does not enter defrost pattern; Thereby the frost on refrigerating evaporator is removed, for defrost;
Situation two: the Temperature numerical gathering when A/D module is not in scope, and sensor temperature is higher than 70 ℃ or during lower than-60 ℃, and refrigeration system is judged as sensor fault; When breakdown of refrigerator is refrigeration sensor fault or freezing sensor fault, compressor carries out loop control in accordance with the following steps to keep the suitable cryogenic temperature of refrigerator:
Steps A 1, the freezing Homes Using TV when normal, compressor operating carries out, after freezing refrigeration, entering steps A 2 for 25 ± 5 minutes;
Steps A 2: the Homes Using TV of the refrigeration when normal, compressor operating carries out, after refrigeration, entering steps A 3 for 20 ± 5 minutes;
Steps A 3: compressor shutdown 25 ± 5 minutes, and heater does not enter defrost pattern; Thereby be refrigerating evaporator defrost
Situation three: when breakdown of refrigerator is defrosting sensor fault, compressor, all the time according to normal control method refrigeration, is shut down and heater initiatively enters defrost pattern and move 40 ± 5 minutes backed off after randoms, helps refrigerating evaporator defrost.
Claims (1)
