Below in conjunction with accompanying drawing, the control method according to the refrigeration plant with frequency-changeable compressor of the embodiment of the present invention is described.
Fig. 1 is the flow chart of control method that has according to an embodiment of the invention the refrigeration plant of frequency-changeable compressor.As shown in Figure 1, there is according to an embodiment of the invention the control method of the refrigeration plant of frequency-changeable compressor, comprise the steps:
Step S101: when refrigeration plant powers on, carry out self check.
Wherein, refrigeration plant is for example but is 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.Take the frequency conversion type refrigerator as example, and after being bought by the user as refrigerator, when energising is used first, after energising, refrigerator carries out self check (the commodity inspection pattern carried as refrigerator), whether normally detects each components and parts of refrigerator etc.
Step S102: if self check is passed through, controlling refrigeration plant enters noise reduction mode and moves with the first desired speed to control frequency-changeable compressor, and under noise reduction mode in running, detect and whether receive fast cold pattern or quick-frozen mode request signal, wherein, when frequency-changeable compressor moves under the first desired speed, the noise that frequency-changeable compressor produces is less than preset value.
For example, refrigerator in self check by rear (all normal such as each components and parts of refrigerator etc.), refrigerator enters the noise reduction mode operation automatically, under this noise reduction mode during refrigerating operaton, refrigerator is controlled frequency-changeable compressor and is moved with the first desired speed, this first desired speed is a less rotating speed, like this, the large noise that can effectively avoid the high rotating speed operation of frequency-changeable compressor to produce, that is to say, the noise produced when refrigerator moves under the first rotating speed can be accepted by the user, technologically speaking, the noise that can control the frequency-changeable compressor generation is less than preset value, for example preset value is not more than 35 decibels.
As from the foregoing, for example refrigerator is when starting first, because environment temperature is higher, directly control frequency-changeable compressor during existing mode and control compressor according to environment temperature and move with suitable rotating speed, and while starting first such as refrigerator, because environment temperature is relatively high, therefore, in existing mode, frequency-changeable compressor will be with higher rotating speed operation, produce large noise, the user is easy to produce complaint.Therefore, the method of the embodiment of the present invention is after refrigerator completes self check, frequency-changeable compressor is not directly according to control frequency-changeable compressors such as environment temperatures, with higher rotating speed, to move, but make the rotating speed operation of frequency-changeable compressor with a less, thereby when meeting certain refrigeration demand, also can effectively lower the large noise that the high rotating speed of frequency-changeable compressor sends, avoid the user to produce complaint, bring certain advantage to refrigerator, promote the market competitiveness of refrigerator.
Step S103: if receive fast cold pattern or quick-frozen mode request signal, control refrigeration plant and go to the rotating speed that moves and promote frequency-changeable compressor under fast cold pattern or quick-frozen pattern.
Be that refrigerator is under noise reduction mode in running, if receive fast cold pattern or quick-frozen mode request signal, directly jump out noise reduction mode and go under fast cold pattern or quick-frozen pattern and move, now, refrigeration demand according to the cold pattern of speed or quick-frozen pattern, adjust immediately the rotating speed of frequency-changeable compressor, to meet the refrigeration demand of the cold or quick-frozen of speed.As a concrete example, the control panel of refrigerator has quick-frozen pattern and/or the fast cold mode button of selecting for the user usually, and this is also the ubiquitous function of current refrigerator, after the user clicks, sends the cold pattern of above-mentioned speed or quick-frozen mode request signal.
Step S104: control refrigeration plant and enter normal mode of operation after refrigeration plant has freezed under the cold pattern of speed or quick-frozen pattern.After quick-frozen and fast cold junction bundle, refrigerator enters normal mode of operation, according to the setting of user's reality, controls the pattern of the operation of refrigerator.When the user starts the cold or quick-frozen of speed, can jump out immediately noise reduction mode and go to the cold or quick-frozen mode operation of speed, thereby guarantee the refrigeration performance of refrigerator when meeting consumers' demand.
Wherein, after refrigeration plant enters normal mode of operation, comprising:
1, judge whether refrigeration plant meets the refrigeration condition.Judge whether to meet the refrigeration condition according to the temperature in temperature of the setting of user's reality etc. and current refrigerator compartment.
If 2 meet the refrigeration condition, control that refrigeration plant is freezed and adjust in real time the rotating speed of frequency-changeable compressor according to current cryogenic temperature, according to the setting of user's reality, control refrigerator and move normally.
Further, the method of the embodiment of the present invention also comprises: if fast cold pattern or quick-frozen mode request signal do not detected in running under noise reduction mode, when refrigeration plant, after reaching Preset Time the running time under noise reduction mode, control refrigeration plant and enter normal mode of operation.
For example, refrigerator is in above-mentioned noise reduction mode running, if do not detect all the time such as the cold pattern of speed or quick-frozen mode request signal, noise reduction mode will maintain a Preset Time, after this Preset Time finishes, automatically control refrigerator and enter above-mentioned normal mode of operation.
In above-mentioned example, Preset Time can be determined based on experience value by the technical staff.Particularly, for example, after noise reduction mode continuous service certain hour (10 minutes-30 minutes), when between refrigerator, indoor temperature starts with respect to refrigerator, temperature is low a lot, the condition relevant with indoor current temperature according to the rotating speed of frequency-changeable compressor is known, because an indoor temperature has descended, therefore, even enter above-mentioned normal mode of operation, the rotating speed of compressor can be not too high yet, and then the noise produced is little during with respect to the starting up, can be received by the user, therefore, control refrigeration plant when refrigeration plant and enter normal mode of operation after reaching Preset Time the running time under noise reduction mode, can promote the refrigeration performance of refrigerator, the noise of effectively avoiding refrigerator to produce too high simultaneously, avoid the user to produce complaint, and then the market competitiveness of lifting refrigerator.
In addition, Preset Time also can be variable time, and the cryogenic temperature set of the duration of Preset Time and user is relevant with current actual temperature.For example, before refrigerator moves under noise reduction mode, the temperature that can set by detecting the interior Current Temperatures of refrigerator compartment and user, when difference is larger between the two, can the Preset Time setting is relatively longer, like this, can guarantee when noise reduction mode finishes, the difference of the temperature reality that the Current Temperatures in refrigerator compartment and user set can be not excessive, thereby avoid the frequency-changeable compressor rotating speed too high, and then avoided the appearance of large noise.
As a concrete example, take refrigerator as example.As shown in Figure 2, the control method that this has the refrigeration plant of frequency-changeable compressor, comprise the steps:
Step S201: power on first, as refrigerator has just been bought by the user, use first.
Step S202: the commodity inspection pattern, after powering on, refrigerator carries out self check.
Step S203: noise reduction mode, after self check is passed through, enters the noise reduction mode operation.
Step S204: whether cold the or quick-frozen pattern of judgement speed starts, and if not, performs step S205, otherwise the cold or quick-frozen mode operation of speed, and perform step S206 after end.
Step S205: judge that whether noise reduction mode reaches Preset Time running time, if it is performs step S206, otherwise returns to step S203.
Step S206: enter normal mode of operation.
Step S207: finish.
Control method according to the refrigeration plant with frequency-changeable compressor of the embodiment of the present invention, after refrigeration plant (as refrigerator) energising and self check are passed through, control refrigeration plant and enter the noise reduction mode operation, after this noise reduction mode starts, the frequency-changeable compressor rotating speed is reduced to lower rotating speed.And enter the normal mode of operation operation after selecting or move Preset Time according to the user, can guarantee that frequency-changeable compressor makes a noise less, avoid the user to complain, also can guarantee to a certain extent refrigeration performance, effectively promote the market competitiveness of refrigeration plant.
