Description
Technical field:
The present invention relates to a kind of control methods of mechanical air door variable-frequency electric brain refrigerator.
Background technique:
When in use, compressor start-stop is by refrigerated storage temperature master control to mechanical air door refrigerator, and air quantity and cooling capacity cannot achieve conjunction
Reason distribution: (1) when circumstance temperature is lower, refrigerator load is small, and temperature of refrigerating chamber cooling is fast, it is slow to rise again, and the compressor shutdown time is long, at this time
If not manually adjusting mechanical air door gear size, cooling capacity is redistributed, following phenomenon will occur: refrigerated storage temperature has met storage temperature
When spending, but cryogenic temperature is still not up to storage temperature, excessively high so as to cause cryogenic temperature；
(2) when circumstance temperature is higher, refrigerator load is big, and temperature of refrigerating chamber cooling is slow, it is fast to rise again, and the compressor shutdown time is short, this
Shi Ruo does not manually adjust mechanical air door gear size, redistributes cooling capacity, and following phenomenon will occur: cryogenic temperature has been far below storage
When hiding temperature, but refrigerated storage temperature is still not up to storage temperature, and big so as to cause compressor Homes Using TV, power consumption increases.User behaviour
Make relatively complicated, cannot achieve the intelligentized control method of mechanical air door product.
If you need to meet each compartment temperature, user must guide according to relevant specification and adjust for different environment temperatures
The temperature gear of mechanical air door gear and refrigerating chamber carries out the reasonable distribution of cooling capacity and air quantity, but its operation is relatively complicated, and easily
Maloperation is caused, cause power consumption excessively high or influences food storage quality.
Summary of the invention:
The present invention is to provide a kind of mechanical air door variable-frequency electric brain refrigerator to solve the above-mentioned problems of the prior art
Control method, the present invention is by monitoring temperature of refrigerating chamber, environment temperature and time control, to determine compressor and blower
Revolving speed and start-stop.
The technical solution of the present invention is as follows: a kind of control method of machinery air door variable-frequency electric brain refrigerator, including
1) when refrigerator powers on for the first time, when refrigerating chamber satisfaction opens temperature or more: compressor is first with Rc1 rotation speed operation, blower
First with Rf1 rotation speed operation, 10min is run, judges which circumstance temperature section environment temperature Te belongs to, blower executes corresponding revolving speed, pressure
Contracting machine executes corresponding revolving speed；
2) after running 20min, refrigerating chamber sensor is still not up to after refrigerating chamber stops temperature, and compressor rotary speed rises one grade of fortune
Row, until refrigerating chamber sensor reaches after refrigerating chamber stops temperature, compressor shuts down, until compressor dwell time reaches 10
Minute, refrigerating chamber, environment temperature sensor temperature are determined again；
3) when low temperature, relevant temperature segment is judged according to specific circumstance temperature, refrigerator integral load is small at this time, compressor, wind
Machine uses lower revolving speed respectively, slows down the cooling rate of refrigerating chamber, stays in cooling capacity more in freezing chamber, to realize cold
Hiding, cryogenic temperature meet storage temperature requirement simultaneously, and reduce noise and energy consumption；
4) when high temperature, relevant temperature segment is judged according to specific circumstance temperature, refrigerator integral load is big at this time, compressor, wind
Machine uses higher revolving speed respectively, accelerates the cooling rate of refrigerating chamber, makes in cooling capacity distribution according to need to refrigerating chamber and freezing chamber,
To realize refrigeration, cryogenic temperature while meet storage temperature requirement, and energy consumption drops.
Further, compressor rotary speed upshift number highest is limited to 2 times.
The invention has the following beneficial effects: no matter refrigerator is in any circumstance temperature in scope of design, the mechanical air door of holding
It dispatches from the factory gear (without adjusting the size of mechanical air door), realizes air quantity and cooling capacity reasonable layout, refrigeration, freezing can meet simultaneously
Storage temperature realizes mechanical air door refrigerator temperature intelligentized control method, and reduces power consumption.By judge circumstance temperature sensor temperature and
Refrigeration sensor temperature increases freezing temperature-controlled precision and reduces in conjunction with controlling the revolving speed of compressor and the revolving speed of blower to reach
The purpose of energy consumption.
Detailed description of the invention:
Fig. 1 is control method flow chart of the invention.
Specific embodiment:
The present invention will be further described below with reference to the drawings.
Such as Fig. 1, a kind of control method of mechanical air door variable-frequency electric brain refrigerator of the present invention, it is characterised in that: including
1) when refrigerator powers on for the first time, when refrigerating chamber satisfaction opens temperature or more: compressor is first with Rc1 rotation speed operation, blower
First with Rf1 rotation speed operation, 10min is run, judges which circumstance temperature section environment temperature Te belongs to, blower executes corresponding revolving speed, pressure
Contracting machine executes corresponding revolving speed；
2) after running 20min, refrigerating chamber sensor is still not up to after refrigerating chamber stops temperature, and compressor rotary speed rises one grade of fortune
Row, until refrigerating chamber sensor reaches after refrigerating chamber stops temperature, compressor shuts down, until compressor dwell time reaches 10
Minute, refrigerating chamber, environment temperature sensor temperature are determined again；
3) when low temperature, relevant temperature segment is judged according to specific circumstance temperature, refrigerator integral load is small at this time, compressor, wind
Machine uses lower revolving speed respectively, slows down the cooling rate of refrigerating chamber, stays in cooling capacity more in freezing chamber, to realize cold
Hiding, cryogenic temperature meet storage temperature requirement simultaneously, and reduce noise and energy consumption；
4) when high temperature, relevant temperature segment is judged according to specific circumstance temperature, refrigerator integral load is big at this time, compressor, wind
Machine uses higher revolving speed respectively, accelerates the cooling rate of refrigerating chamber, makes in cooling capacity distribution according to need to refrigerating chamber and freezing chamber,
To realize refrigeration, cryogenic temperature while meet storage temperature requirement, and energy consumption drops.
