Referring to Fig. 3, in the controlling method for refrigerator of the present invention from carrying out compressor operating step S100.Specifically, the temperature by surveying locker room 11 to 13 also utilizes control module 110 that temperature and the predetermined temperature of measuring compared, to determine whether needing compressor 40 to move.If the result of step S100 needs compressor 40 operations, then start the operation of compressor.In this example, refrigerant only is transported in one or more locker rooms that need to freeze, and also is that temperature is higher than in the locker room of predetermined temperature, so only refrigerating operation is carried out in the specific memory chamber.
Then, determine in step S200 whether compressor is in running status.
If determine among the step S200 that compressor is in running status, then in step S300, carry out the driving control step of the driving of control multi-chamber refrigerator.Refrigerant is transported in one or more newly-increased chambers of not moving in compressor operating step S100 and needing to freeze.On the other hand, when the temperature of one or more locker room reaches predetermined temperature, stop the refrigerant conveying operations.By above-mentioned steps, the temperature in all locker rooms 11 to 13 is equal to or less than the predetermined temperature time, and compressor 40 is out of service.
After compressor 40 is out of service, implement pressure equalization step in the controlling method for refrigerator of the present invention at step S400.In pressure equalization step S400, the opening and closing of control module 110 by-pass valve controls 71 to 73 are so that reach balance with refrigerant pressure in the coolant channel that locker room 11 to 13 is connected.
Fig. 4 A shows among the present invention the flow chart of compressor operating step S100 in the controlling method for refrigerator.Shown in Fig. 4 A, control module 110 receives the signal that transmits from temperature sensor 21 to 23 and utilizes acquisition of signal the step S110 to go out first temperature of locker room 11 to 13.Detect after first temperature, whether have one or more to be higher than predetermined temperature in first temperature that control module 110 is determined to measure in step S120.Be higher than predetermined temperature if in step S120, define one or more, the control module valve that by-pass valve control driver element 140 is opened corresponding to locker room among the step S130 in step S130.Then, determine in step S140 whether preset time T 1 is finished.If being in opening, the valve of locker room passed through scheduled time T1, temperature sensor 21 to 23 is surveyed second temperature of locker room 11 to 13, simultaneously, whether there is one or more to be higher than predetermined temperature in second temperature that control module 110 is determined to measure in step S140.Scheduled time T1 makes refrigerant reach the needed time of pressure balance under the valve opening state, its preferred time value is about three seconds.If have one or more to be higher than predetermined temperature in second temperature of determining to measure in step S150, control module 110 by-pass valve control driver element 140 in step S160 is further opened the valve of respective stored chamber.Then, control module is controlled driven compressor unit 120 and is made compressor 40 operations in step S170, make corresponding locker room obtain refrigeration like this.
Fig. 4 B shows the flow chart that drives control step S300 among the present invention in the controlling method for refrigerator.Shown in Fig. 4 B, when compressor 40 was in running status, control module 110 detected the 3rd temperature of locker room 11 to 13 in step S310.In this example, control module 110 receives signal that transmits from temperature sensor 21 to 23 and the 3rd temperature of utilizing this signal measuring locker room 11 to 13.Then, whether there is one or more to be higher than predetermined temperature in the 3rd temperature that control module 110 is determined to detect in step S320.If in step S320, define first or a plurality of temperature be higher than predetermined temperature, then control module 110 at step S330 by-pass valve control driver element 140 to open the valve of respective stored chamber.
Yet, if in step S320, determine neither one or a plurality of predetermined temperature that is higher than in the 3rd temperature of newly-increased locker room, determine in step S340 then first early gate is in the 3rd temperature of locker room of opening whether one or more predetermined temperatures that are not higher than are arranged.Be in the 3rd temperature of locker room of opening one or more predetermined temperatures that are higher than are arranged if in step S340, determine first early gate, then return the operation of step S310.
Yet, if the 3rd temperature that definite first early gate is in the locker room of opening in step S340 is equal to or less than predetermined temperature and does not need further refrigeration, determine in step S350 then whether the temperature of measuring in all locker rooms 11 to 13 is equal to or less than predetermined temperature.If determine that in step S350 thereby the temperature of all locker rooms 11 to 13 is equal to or less than all locker rooms 11 to 13 of predetermined temperature and does not all need refrigeration, then compressor is out of service in step S360.On the contrary, all be equal to or less than predetermined temperature if in step S350, determine the temperature of not all locker room 11 to 13, that is to say, have one or more locker room to need refrigeration, then will be in step S370 corresponding to the valve opening of the locker room of needs refrigeration with the valve closing that does not need the locker room of freezing of remainder.
Fig. 4 C is the flow chart that shows pressure equalization step S400 among the present invention.If compressor 40 is out of service, then control module 110 is carried out pressure equalization step S400.
In pressure equalization step S400, control module 110 is opened all valves of closing 71,71 and/or 73 at step S410 by-pass valve control control module 140.All valves 71 to 73 are in all that opening reaches scheduled time T2 so that the pressure of refrigerant reaches balance.Correspondingly, the pressure of the refrigerant in the kind of refrigeration cycle in the coolant channel obtains balance, and like this, compressor 40 can easily be realized restarting.Then, determine in step S420 whether preset time T 2 is finished.If the scheduled time, T2 finished, then control module 110 in step S430 by-pass valve control driver element 140 with all valve closings.
