Description
Technical field
It is to be related to a kind of refrigerator continuously to run conversion method more specifically the present invention relates to refrigerator technical field.
Background technology
The converter technique of refrigerator energy-conservation, low noise, quick-frozen etc. many-side there is more obvious effect, into
It is the inexorable trend of cooling refrigerator industry development.In existing frequency conversion refrigerator, the compressor of frequency conversion refrigerator still needs frequent opening
Stop, i.e. the start-stop frequency of compressor is still higher, the frequent starting of compressor can cause service life is reduced, noise is big etc.
Problem.
The content of the invention
Conversion method is continuously run it is an object of the invention to provide a kind of refrigerator, by frequency-changeable compressor with most suitable
The slow-speed of revolution continuously runs to maintain target temperature stabilization, so that refrigerator power consumption is reduced, to overcome the deficiencies in the prior art.
What goal of the invention of the invention was realized in：A kind of refrigerator continuously runs conversion method, and the refrigerator is provided with cold
Freeze room, the frequency-changeable compressor of refrigerator is provided with maximum (top) speed Smax and minimum speed Smin, refrigerating chamber and sets temperature-sensitive head and every X
Minute detection temperature-sensitive head temperature value tn, refrigerating chamber cooling rate Pt is tn-tn-1, it is characterised in that：Frequency-changeable compressor is on for the first time
Run with rotating speed S0 after electricity, then every N minute calculating refrigerating chamber cooling rate Pt and accordingly adjustment frequency-changeable compressor rotating speed, change
The rotating speed Sn controls rule of frequency compressor meets following table：
| Pt | △ t ＞ a | B ＜ △ t≤a | C ＜ △ t≤b | △t≤c |
| Pt ＜ 0 | Rotating speed increases A until reaching Smax | Rotating speed reduction B is until reach Smin | Rotating speed reduction B is until reach Smin | Shut down or run with Smin |
| Pt=0 | Rotating speed increases A until reaching Smax | Rotating speed increases A until reaching Smax | Maintain rotating speed constant | Shut down or run with Smin |
| Pt ＞ 0 | Rotating speed increases A until reaching Smax | Rotating speed increases A until reaching Smax | Rotating speed increases A until reaching Smax | Shut down or run with Smin |
Wherein, △ t are the differences of temperature-sensitive head temperature and design temperature.
Above-mentioned refrigerator continuously runs conversion method, as △ t≤c, calculates available machine time T1, if T1 >=M minutes, become
Frequency compressor shutdown, if T1 ＜ M minutes, frequency-changeable compressor is run with minimum speed Smin.
Refrigerator sets refrigerating box, and casing back is provided with air channel, blower fan and refrigerating chamber air door are set in air channel.
Above-mentioned refrigerator continuously runs conversion method, also including forced refrigeration pattern, under forced refrigeration pattern, and frequency conversion pressure
Contracting machine is run with S1 speed and blower fan keeps middling speed.
The beneficial effects of the invention are as follows：
The energy-saving effect of refrigerator frequency-changeable compressor is embodied in the slow-speed of revolution, is verified after tested, the rotating speed of frequency-changeable compressor it is more low more
Energy-conservation.The present invention continuously runs to maintain target temperature stabilization by frequency-changeable compressor with the most suitable slow-speed of revolution, consumes refrigerator
The control of electricity ratio Homes Using TV also wants energy-conservation 7% or so in 80% frequency conversion refrigerator.
Brief description of the drawings
Fig. 1 is refrigeration for refrigerator amount-time diagram that conversion method is continuously run using refrigerator of the present invention.
In accompanying drawing,Represent compressor refrigerating capacity,Temperature-sensitive head temperature curve is represented,Represent drop
Warm speed.
