Specifically, operational tapses can directly correspond to the setting temperature in cool room, can also characterize the temperature in cool roomControl scope, such as 2 DEG C, 4 DEG C, 6 DEG C etc., or 1-7 gears, wherein 1 grade of characterization control temperature is at 8 DEG C or so, 7 grades of characterization control temperatureDegree is at 1 DEG C or so, and temperature value is lower corresponding to gear, and the refrigeration compartment temperature collected is higher, and Homes Using TV is higher, gear pairThe temperature value answered is higher, and Homes Using TV is lower.
Wherein, the timer time that defrost starts the cycle was the upper electric moment of refrigeration plant, such as, detecting that Homes Using TV isWhen 30%, defrosting operation was performed according to the first defrost periodic Control evaporator, i.e., by the first defrost cycle from the upper electric momentAfterwards, defrosting operation is started.
In any of the above-described embodiment, it is preferable that also include：Recording unit 312, based on being opened from the moment is specifiedWhen, and record from the specified moment after preset duration, multiple actual run times of the compressor under multiple working frequencies；ReallyOrder member 304 is additionally operable to：Determine correction factor corresponding to multiple working frequencies；Defrosting control device 300 also includes：Amending unit314, for being modified respectively to multiple actual run times according to correction factor, to generate amendment run time；It is it is determined that singleMember 304 is additionally operable to：According to amendment run time and preset duration, it is determined that average Homes Using TV, average Homes Using TV is defined as pressingThe Homes Using TV of contracting machine, wherein, preset duration is less than the defrost cycle.
In this embodiment, when compressor is frequency-changeable compressor, because the running frequency of compressor is variable, thereforeOperational factor is fixed, and Homes Using TV is definite value or underrange, by detecting compressor respectively in difference in specified preset durationActual run time under working frequency, then modified index is repaiied to the actual progress time according to corresponding to different frequenciesJust, obtain correcting run time, Homes Using TV is determined with preset duration by correcting run time, can be by the work of frequency-changeable compressorMake process approximate transform to determine the frequency course of work, and then determine Homes Using TV, and then meet evaporator corresponding to frequency-changeable compressorDefrost demand, while evaporator environment temperature sensor need not be set, in the reasonable selection defrost cycle, reduce evaporationThe frosting probability of device, and then the refrigerating efficiency of refrigeration plant can be improved.
Specifically, the median in multiple working frequencies can be set to standard value, i.e. correction factor corresponding to medianFor 1, it is more than 1 more than correction value corresponding to the working frequency of median, it is small less than correction value corresponding to the working frequency of medianIn 1, compressor is then obtained under different operating frequency according to actual run time of the compressor under different operating frequencyRun time is corrected, because the relative operation time of different operating frequency and the ratio of actual run time are according to work frequencyBeing incremented by for rate increases successively, therefore when compressor works in lower frequency, the ratio of relative operation time and actual run timeValue is smaller, and when compressor is in higher frequency operation, the ratio of relative operation time and actual run time is larger, i.e., corresponding sameThe relative operation time of sample, for compressor when lower frequency works, actual run time is longer, and compressor is in higher frequency operationWhen, actual run time is shorter.
Wherein, the timer time that defrost starts the cycle is to specify the moment.
In any of the above-described embodiment, it is preferable that the first defrost cycle was 8 hours, and the second defrost cycle was 16 hours, theThree defrost cycles were 34 hours.
Fig. 4 shows the schematic flow diagram of defrosting control method according to still a further embodiment.
As described in Figure 4, when compressor is invariable frequency compressor, defrosting control side according to another embodiment of the inventionMethod, including：Step 402, when electric on detecting refrigeration plant, the operational tapses of refrigeration plant are determined, and detect refrigeration and setStandby refrigeration compartment temperature；Step 404, according to operational tapses and refrigeration compartment temperature, the Homes Using TV of compressor is determined；Step 406, examineThe relation surveyed between Homes Using TV and the first default accounting threshold value, and the second default accounting threshold value；Step 408, detecting outWhen probability is less than the first default accounting threshold value, according to the first defrost cycle, controls and defrosting operation is performed to evaporator；Step 410,When detecting Homes Using TV more than or equal to the first default accounting threshold value, and being less than or equal to the second default accounting threshold value, according toIn the second defrost cycle, control and defrosting operation is performed to evaporator；Step 412, detecting Homes Using TV more than the second default accountingDuring threshold value, according to the 3rd defrost cycle, control and defrosting operation is performed to evaporator.
Wherein, the first defrost cycle was 8 hours, and the second defrost cycle was 16 hours, and the 3rd defrost cycle was 34 hours, theOne default accounting threshold value is 35%, and the second default accounting threshold value is 65%.
Fig. 5 shows the schematic block diagram of the refrigeration plant of the embodiment of the present disclosure.
As shown in figure 5, according to the refrigeration plant 50 of the embodiment of the embodiment of the present disclosure, including memory 502, processor504 and it is stored in the computer program that can be run on the memory 502 and on the processor 404, wherein memory 502It can be connected between processor 504 by bus, the processor 504 is used to perform the computer stored in memory 502The step of defrosting control method described in example is performed as described above is realized during program.
Computer-readable recording medium according to still another embodiment of the invention, except with the whole in embodiment sevenOutside technical characteristic, for above-mentioned refrigeration plant, computer program (instruction) is stored thereon with, it is characterised in that：Computer journeyThe step of sequence (instruction) realizes any one defrosting control method in above-described embodiment when being executed by processor.
In this embodiment, because computer-readable recording medium is used for above-mentioned refrigeration plant, thus there is above-mentioned systemWhole beneficial effects of cool equipment, are stored thereon with computer program (instruction), and computer program (instruction) is executed by processorThe step of Shi Shixian above-mentioned defrosting control methods, thus whole beneficial effects with above-mentioned defrosting control method.
Technical scheme is described in detail above in association with accompanying drawing, by technical scheme, by defaultAccounting threshold value, and the relation between the Homes Using TV of compressor and default accounting threshold value is detected, with according to Homes Using TV and default accountingRelation between threshold value, it is determined that corresponding defrost starts the cycle, and then cycle execution defrosting operation is started by corresponding defrost,Because the Homes Using TV of compressor is higher, show that the frequency of use of evaporator is higher, namely on evaporator frosting probability it is also higher,Cycle startup defrosting operation is started by the defrost corresponding to, compared with defrosting control scheme of the prior art, it is not necessary toTemperature sensor is set to gather the temperature of evaporator at evaporator, on the one hand, temperature sensor at evaporator can be cancelledSetting, simplify device and set, corresponding simplify control process, improve the preparation efficiency of refrigeration plant, on the other hand, be advantageous toThe normalized control of refrigeration plant.
