Description
Technical field
The refrigerator of selecting reversing motor for use that the present invention relates to a kind of refrigerator field just/despining compressor operating control method, particularly relate to a kind of when just starting, the stator poles that makes compressor electric motor is 2 utmost points, and the positive direction rotation obtains big cold power, after reaching uniform temperature, make the stator poles of compressor convert 4 utmost points to, and opposite spin can keep the refrigerator of selecting reversing motor for use that the user sets temperature just/despining compressor operating control method (FORWARD/REVERSE ROTATIONCOMPRESSOR DRIVING METHOD FOR REFRIGERATOR EQUIPED WITH POLE CHANGEMOTOR).
Background technology
In general, compressor is the device that utilizes the revolving force compression condensation agent of motor internal, is applied to refrigerator and air conditioner, particularly be applied to the compressor electric motor of refrigerator, as shown in Figure 1, this motor is made up of stator and rotor, and can only travel at the uniform speed (3600rpm).
When this compressor electric motor of being made up of 2 utmost point stators is used for refrigerator, make it have the representative operational mode of refrigerator: refrigerating mode and standard operational mode rapidly.In actual motion, rapidly the time of refrigerating mode, as shown in Figure 2, have only 10% of time used, all the other times are the standard operational mode.
It is big to move the temperature range that refrigerating mode rapidly will regulate, so that above-mentioned pattern is that high-speed cruising is finished cooling rapidly with fixing speed, but the temperature range that the standard operational mode is regulated is little, so this high-speed cruising increases noise and power consumption on the contrary, and bring bad influence to product.
But the compressor electric motor of actual refrigerator is ignored everything, is with refrigerating mode high-speed cruising rapidly.
As mentioned above, the freeze cycle of the refrigerator of producing according to prior art is by for the high cold power freeze cycle of the cold air of supply refrigerating chamber be the low cold power freeze cycle of the cold air of supply refrigerating chamber, at this moment, cold power freeze cycle of above-mentioned height or low cold power freeze cycle, because of the length of expansion gear is identical, so can not reach best freeze cycle under the different operational modes.
Fig. 3 is a current refrigerator freeze cycle schematic diagram.As shown in Figure 3, according to the kind of refrigeration cycle of prior art, it comprises the low temperature that evaporimeter is discharged, the compressor 1 that low pressure condensed steam sucked and be compressed into high temperature, high steam; Heat in the high temperature that above-mentioned compressor 1 is discharged, the condensed steam of high pressure is discarded in water or the air, and converts the condenser 2 of high pressure saturated solution to; The high pressure saturated solution that above-mentioned condenser 2 is discharged is sucked in the condensing agent of low temperature, low pressure by capillary 3, and carries out heat exchange by the air in evaporation and the refrigerating chamber, thereby makes first evaporimeter (F-EVA) of the air cooling-down in the refrigerating chamber; The high pressure saturated solution that above-mentioned condenser 2 is discharged is sucked in the condensing agent of low temperature, low pressure by capillary 3, and carries out heat exchange by the air in evaporation and the refrigerating chamber, thereby makes second evaporimeter (R-EVA) of the air cooling-down in the refrigerating chamber.
At first, when carrying out freezing operation (high refrigeration), the condensing agent of the HTHP of compressed machine 1 compression flows into after condenser 2 condensations, becomes the condensing agent of low-temp low-pressure in the process of capillary 3 of flowing through.
Afterwards, first evaporimeter (F-EVA) sucks the condensing agent of above-mentioned low-temp low-pressure and discharges the saturated vapor that does not have moisture through pervaporation in refrigerating chamber.
When refrigerating operation (low refrigeration), the condensing agent of the HTHP of compressed machine 1 compression flows into after condenser 2 condensations, becomes the condensing agent of low-temp low-pressure in the process of capillary 3 of flowing through.
Afterwards, second evaporimeter (R-EVA) suck above-mentioned low-temp low-pressure condensing agent and through pervaporation and and refrigerating chamber between heat exchange and discharge cold air.
Because above-mentioned refrigerator freeze cycle adopted is the compressor that can only be rotated in the forward and produces high output all the time, therefore, even it is relatively stable and when not needing strong cold power,, thereby increase electric power consumption because carry out the positive rotation of compressor all the time in the temperature of refrigerator.
For addressing the above problem, in refrigerator, adopt the compressor that carries out forward and reverse rotation as required, thereby reduce the technology of power consumption, that is to say, after refrigerator moves a period of time, if detect its stable status, make compressor to the opposite direction running that produces weak cold power, thereby reduce power consumption.
Said method is when originally compressor starts, and moves opposite spin under the state of the temperature stabilization in refrigerator, and the temperature in refrigerator is than the rotation of operation positive direction under the very high state of the temperature of setting.But traveling at the uniform speed of the coil by fixing motor stator, exist when the frequent On/Off of high-speed cruising and compressor loss serious in operation and starting/the big problem of noise when stopping
