Below in conjunction with accompanying drawing, the control method with the refrigeration plant of frequency-changeable compressor according to the embodiment of the present invention is described.
Fig. 1 is the flow chart of the control method of the refrigeration plant according to an embodiment of the invention with frequency-changeable compressor.As shown in Figure 1, there is the control method of the refrigeration plant of frequency-changeable compressor according to an embodiment of the invention, comprise the steps:
Step S101: when refrigeration plant powers on, carries out self-inspection.
Wherein, refrigeration plant such as but be not limited to: refrigerator, refrigerator-freezer or wine cabinet (Electronic Wine Cabinet), wherein, the refrigerator of above-mentioned indication, refrigerator-freezer or wine cabinet are refrigerator, refrigerator-freezer or the wine cabinet with frequency-changeable compressor.For frequency conversion type refrigerator, after being bought by user in refrigerator, when energising uses first, after powered up, refrigerator carries out self-inspection (as the commodity inspection pattern that refrigerator carries), whether normally detects each components and parts of refrigerator etc.
Step S102: if self-inspection is passed through, then control refrigeration plant enters physically sensitive mode and enters normal mode of operation to control controlling refrigeration plant after frequency-changeable compressor runs Preset Time with the first desired speed, wherein, when frequency-changeable compressor runs under the first desired speed, the noise that frequency-changeable compressor produces is less than preset value.
Such as, refrigerator passes through rear (such as each components and parts of refrigerator etc. are all normal) in self-inspection, refrigerator automatically enters physically sensitive mode and runs, under this physically sensitive mode during refrigerating operaton, refrigerator controls frequency-changeable compressor and runs with the first desired speed, this first desired speed is a less rotating speed, like this, frequency-changeable compressor height rotating speed can be effectively avoided to run the large noise produced, that is, the noise produced when refrigerator runs under the first rotating speed can be easily accepted by a user, technologically speaking, the noise that can control frequency-changeable compressor generation is less than preset value, such as preset value is not more than 35 decibels.
As from the foregoing, such as refrigerator is when initiating switchup, because environment temperature is higher, directly control during existing mode frequency-changeable compressor environmentally temperature control compressor and run, and during such as refrigerator initiating switchup with suitable rotating speed, because environment temperature is relatively high, therefore, in existing mode, frequency-changeable compressor runs with higher rotating speed, produce large noise, user is easy to produce complaint.Therefore, the method of the embodiment of the present invention is after refrigerator completes self-inspection, frequency-changeable compressor is not that the control frequency-changeable compressors such as direct environmentally temperature run with higher rotating speed, but frequency-changeable compressor is run with a relatively little rotating speed, thus while meeting certain refrigeration demand, also effectively can lower the large noise that frequency-changeable compressor height rotating speed sends, avoid user to produce complaint, bring certain advantage to refrigerator, promote the market competitiveness of refrigerator.
Wherein, after refrigeration plant enters normal mode of operation, comprising:
1, judge whether refrigeration plant meets cryogenic conditions.Namely judge whether to meet cryogenic conditions according to the temperature in temperature of the setting of user's reality etc. and current refrigerator compartment.
If 2 meet cryogenic conditions, then control refrigeration plant and carry out freezing and adjust the rotating speed of frequency-changeable compressor according to current cryogenic temperature in real time.Namely according to the setting of user's reality, control refrigerator and run normally.
Further, refrigerator is in above-mentioned physically sensitive mode running, if body sense mould maintains run a Preset Time, after this Preset Time terminates, automatically controls refrigerator and enters normal mode of operation.Refrigerator enters normal mode of operation, namely according to the setting of user's reality, controls the pattern of the operation of refrigerator, thus ensure the refrigeration performance of refrigerator while meeting consumers' demand.
In the examples described above, Preset Time can be determined based on experience value by technical staff.Specifically, when after physically sensitive mode continuous service certain hour (such as 10 minutes-30 minutes), when temperature indoor between refrigerator starts relative to refrigerator, temperature is low a lot, the condition relevant according to the temperature that the rotating speed of frequency-changeable compressor is current with an indoor, because an indoor temperature have dropped, therefore, even if enter above-mentioned normal mode of operation, the rotating speed of compressor also can not be too high, and then the noise produced is relative to little during starting up, can be received by user, therefore, after refrigeration plant reaches Preset Time the running time under physically sensitive mode, control refrigeration plant enter normal mode of operation, namely the refrigeration performance of refrigerator can be promoted, the noise simultaneously effectively avoiding refrigerator to produce is too high, user is avoided to produce complaint, and then promote the market competitiveness of refrigerator.
In addition, Preset Time also can be variable time, and the duration of Preset Time is relevant with current actual temperature to the cryogenic temperature that user sets.Such as, before refrigerator runs under physically sensitive mode, by the temperature that the Current Temperatures in detection refrigerator compartment and user set, when difference is larger, can Preset Time be arranged relatively longer, so between the two, can ensure at the end of physically sensitive mode, the difference of the temperature reality of the Current Temperatures in refrigerator compartment and user's setting can not be excessive, thus avoid frequency-changeable compressor rotating speed too high, and then avoid the appearance of large noise.
As shown in Figure 2, apply noise (as the body sense A point in Fig. 2 and body sense B point) that the frequency-changeable compressor with the control method of the refrigeration plant of frequency-changeable compressor of the embodiment of the present invention produces be significantly less than frequency-changeable compressor in existing mode the noise (as the former A point in Fig. 2 and former B point) that produces.
According to the control method with the refrigeration plant of frequency-changeable compressor of the embodiment of the present invention, after refrigeration plant (as refrigerator) is energized and self-inspection is passed through, control refrigeration plant and enter physically sensitive mode operation, after this physically sensitive mode starts, frequency-changeable compressor rotating speed is reduced to lower rotating speed, and control after maintaining operation Preset Time refrigeration plant enter normal mode of operation run, thus, can ensure that frequency-changeable compressor makes a noise less, user is avoided to complain, also refrigeration performance can be ensured to a certain extent, the market competitiveness of effective lifting refrigeration plant.
