Embodiment:
Below in conjunction with accompanying drawing embodiment of the present utility model is further described:
Referring to Fig. 1, Fig. 2, shown in Figure 3, the present invention determines that by the start and end time of being put place, place business by artificial setting commercial show freezer control system is to be in " running " state or " standby " state.
The judgement of recent trend: the busy not busy level data of refrigerator of corresponding time period of a few days before microprocessor 1 is collected current slot and is kept in the eeprom memory 5, whether analyze this busy not busy degree automatically has the trend that increases or disappear, and with this reference as adjustment refrigerator working temperature.
The judgement of instant busy not busy degree: microprocessor 1 is judged the busy immediately not busy degree of current refrigerator with client of interval sampling of number/one of each time period number of times of beverage of taking that opens the door according to door opening times, and with this as the reference of adjusting the refrigerator working temperature.
Control decision: 1 each time period of microprocessor is read once the busy not busy degree of refrigerator of recent identical time period, and according to busy not busy trend of preceding a few days, the temperature that is provided with automatically in the current slot is adjusted grade simultaneously.
" have much to do " in the time period in refrigerator work, adjust the cabinet temperature automatically to lower position; Otherwise then adjust to higher cabinet temperature, so that save power consumption.
During " standby " state, microprocessor 1 is kept the refrigerator temperature automatically in the highest permission working temperature, so that be in the most energy-conservation state.The appropriate time (in advance open time) of microprocessor 1 before the business hours, automatically connect compressor, begin pre-refrigeration process, when refrigerator turns round continuously, required temperature was adjusted coefficient (being judged by the historical experience value) when cabinet when microprocessor 1 will be opened to business according to trade company gentle next day opened to business, and adjustment is opened the time in advance to suitable parameter automatically.Adjusted pre-cooling time leaves in replaces the former data of putting in the eeprom memory 5, next day is promptly by new parameter operation.Can guarantee under the condition that satisfies the requirement of cabinet temperature, to save power consumption to greatest extent.
The clock of controller operation control reference data is provided by the real-time timepiece chip 6 of lithium battery power supply, even the long-time outage of refrigerator still can be kept timing.Not only can avoid the interim outage in market may need the trouble of the time of reseting, can guarantee that more controller moves the correctness and the real-time of clock reference.
Controller has advertising lamp and opens duration accumulating operation device, when being in " running " state at refrigerator, lights advertising lamp; When refrigerator when " running " state forwards " standby " state to, close delay time according to the advertising lamp that the user is provided with, automatic time delay is just closed advertising lamp after a period of time, so that advertising results and saving power consumption when taking into account passenger flow and evacuating.
When compressor shut down and be in " running " state, evaporating fan was pressed several minutes cycle intermittent running, so that the air of circulation exchange refrigerator inside makes the cabinet temperature uniform and stable; Evaporating fan circular gap running not only can be played energy-conservation effect, and helps to prolong fan serviceable life.When compressor shut down and be in " standby " state, owing to needn't consider the homogeneity of refrigerator internal temperature, evaporating fan shut down.
When the cabinet door was opened, evaporating fan shut down automatically, prevented cooling gas leakage, closed until the cabinet door.
Controller has the cabinet door and opens duration accumulating operation device, and after the cabinet door continued to open several minutes, controller sent the indication of reporting to the police, and compressor shuts down, and prevents waste of energy.
Controller has compressor operating time and defrost duration accumulating operation device, when compressor add up reach 5 hours the duration of runs after, controller enters defrost process automatically, the defrost process duration is 15 minutes, when the defrost time arrives back or cabinet temperature and surpasses 10 ℃, automatically stop defrost process, start compressor operation.
Controller also has manual control defrost function, and when the operator pressed " defrost " button, controller entered defrost process, the defrost process duration is 15 minutes, when the defrost time arrives back or cabinet temperature and surpasses 10 ℃, stop defrost process automatically, start compressor operation.
