Description
Technical field
The present invention relates to a kind of freezer compressor with reversing motor just/despining control device and control method, particularly relate to a kind of can be according to the temperature in the refrigerator, make compressor carry out positive rotation or despun while, compressor electric motor what select for use is the reversing motor that adopts Hysterisis Band, make freezer compressor that motor moves under 2 utmost points or 4 utmost point states with reversing motor just/despining control device and control method { FORWARD/REVERSE ROTATION COMPRESSOR DRIVINGAPPARATUS AND METHOD FOR REFRIGERATOR EQUIPED WITH POLE CHANGEMOTOR}.
Background technology
In general, the refrigeration cycle that refrigerator adopted is divided into high refrigeration cycle that is refrigerating chamber supply cold air and the low refrigeration cycle of supplying cold air for reefer.
At this moment, above-mentioned high refrigeration cycle or low refrigeration cycle because of the equal in length of its expansion gear, therefore can not obtain best refrigeration cycle according to different operational modes.For above-mentioned conventional art, will be elaborated with reference to drawing appended behind the literary composition.
Figure 1 shows that general refrigerator freeze cycle skeleton diagram.As shown in the figure, the refrigeration cycle of conventional art comprises low temperature, low pressure condensed steam that the suction evaporator spues and the compressor 1 that is compressed into high temperature, high pressure steam; Heat in the high temperature that above-mentioned compressor 1 is spued, 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 spued is sucked in the condensing agent of low temperature, low pressure by kapillary 3, and carries out heat interchange by the air in evaporation and the refrigerating chamber, thereby makes first evaporator (F-EVA) of the air cooling-down in the refrigerating chamber; , the high pressure saturated solution that above-mentioned condenser 2 is spued is sucked in the condensing agent of low temperature, low pressure by kapillary 3, and carries out heat interchange by the air in evaporation and the reefer, thereby makes second evaporator (R-EVA) of the air cooling-down in the reefer.
At first, when carrying out freezing operation (high refrigeration), the condensing agent of the High Temperature High Pressure of compressed machine 1 compression flows into after condenser 2 condensations, becomes the condensing agent of low-temp low-pressure in the process of kapillary 3 of flowing through.Afterwards, first evaporator (F-EVA) sucks the condensing agent of above-mentioned low-temp low-pressure and discharges the saturated vapour that does not have moisture through pervaporation in refrigerating chamber.
When refrigerating operation (low refrigeration), the condensing agent of the High Temperature High Pressure of process compressor 1 compression flows into after condenser 2 condensations, becomes the condensing agent of low-temp low-pressure in the process of kapillary 3 of flowing through.Afterwards, second evaporator (R-EVA) suck above-mentioned low-temp low-pressure condensing agent and through pervaporation and and refrigerating chamber between heat interchange and discharge cold air.
Here, 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 relatively stable and when not needing big cold power in the temperature of refrigerator, because compressor carries out positive rotation all the time, thereby has increased power consumption.
In order to address the above problem, in refrigerator, adopt the compressor that can carry out forward and reverse rotation as required, thereby reduce the technology of power consumption, promptly, after refrigerator moves a period of time, if detect its stable status, just make compressor to the opposite direction running that produces weak cold power, thereby reduce power consumption.
But, in said method, though carry out reverse rotation in the metastable time at the load of refrigerator, and when refrigerator is in overload, be rotated in the forward, but it is longer to the normal load required time to be in overload operation from refrigerator, thereby reduces refrigeration efficient; And, promptly be that the effect of the saving electric power that reverse rotation produced is also not obvious under the situation of underload.
This shows, above-mentioned existing freezer compressor with reversing motor just/despining control device and control method still have many defectives, and demand urgently further being improved.
For solve have reversing motor freezer compressor just/problem that despining control device and control method exist, relevant manufacturer there's no one who doesn't or isn't seeks solution painstakingly, but do not see always that for a long time suitable method finished by development, and general method does not have appropriate addressing the above problem, and this obviously is the problem that the anxious desire of relevant dealer solves.
Because above-mentioned existing freezer compressor with reversing motor just/defective that despining control device and control method exist, the inventor is based on being engaged in this type of product design manufacturing abundant for many years practical experience and professional knowledge, actively studied innovation, in the hope of found a kind of new freezer compressor with reversing motor just/despining control device and control method, can improve general existing conventional freezer compressor with reversing motor just/despining control device and control method, make it have more practicality.Through constantly research, design, and, create the present invention who has practical value finally through repetition test and after improving.
