That is, during the freezer cooling operation, the freezer temperature tF greatly increases to reach the predetermined freezer temperature (for example, about -12.

On the other hand, when the freezer compartment temperature tF does not fall to the freezer upper limit temperature tFu even after a predetermined time elapses, the alarm sounds and a warning signal is issued to the user, and the compression capacity of the compressor 46 is reduced from The maximum compression capacity restores the normal compression capacity. In addition, in the refrigerating compartment cooling operation, the refrigerating compartment temperature and the refrigerating compartment forced cooling temperature (for example, about 10.0) are compared, and the same process is followed. The processing of adjusting the number of revolutions of rotation is explained in conjunction with step S29 described later. — Furthermore, the defrosting process performed in step S11 is as follows. Regarding the evaporator 52 for freezing, the control unit cumulatively calculates the time for cooling operation of the freezing chamber. When the accumulated calculation time exceeds a predetermined set accumulated calculation time (for example, i 0 hours), the freezing chamber is performed by the defrost heater 98 The defrosting of the generator 52. On the other hand, "the refrigerating evaporator 50 is switched to the three-way valve 68 and the refrigerating chamber cooling operation is terminated".

When the freezing compartment temperature tF is lower than the freezing compartment lower limit temperature tFl in the aforementioned step S2, the process proceeds to step S21 shown in FIG. 6. In this step S21, it is judged whether the compressor 46 is operated at the minimum compression capacity, that is, whether the number of revolutions is the minimum number of revolutions. If it is not the minimum number of revolutions, the process proceeds to step S29, and the operation of the compressor 46 is rotated.

That is, the cooling operation is performed from the temperature inside the box tR'tF first to the refrigerating compartment set upper limit temperature tRu or the freezer set upper limit temperature tFu. As described above, the refrigerator to be controlled is compared with the uncooled side temperature tR, tF and the upper limit temperatures tRu, tFu. When the inside temperature tR, tF becomes the upper limit temperature tRu, tFu, the cooling operation is switched. Fig. 7 is a time chart showing the temperature change in the cabinet at this time. As shown in the figure, the conventional refrigerator, for example, does not consider at all what the temperature of the refrigerator compartment tR · during the freezer cooling operation. Therefore, as shown by the dotted line, even if the refrigerating compartment temperature tR exceeds the refrigerating compartment upper limit temperature tRu 'at time T1 until the freezing compartment temperature tF reaches the freezing compartment lower limit temperature tF 1 at time T2, the freezing compartment cooling operation is continued.

On the other hand, the refrigerator is switched from the freezer cooling operation to the refrigerator cooling operation at time T1 when the refrigerator temperature tR exceeds the upper limit temperature tRu of the refrigerator compartment. Therefore, the inside of the refrigerating compartment 14 and the freezing compartment 22 can be kept at an appropriate low temperature. In addition, in the above-mentioned refrigerator, the cooling operation is switched when the temperatures tR and tF in the uncooled side do not exceed the upper limit temperatures tRu and tFu, and when the temperatures tF and tR in the cool side reach the lower limit temperatures tF1 and tR1. Fig. 8 is a time chart showing the temperature change in the box at this time. As shown by the dotted line in the figure, for example, in the freezer cooling operation, if it is only judged whether the refrigerator compartment temperature tR1 exceeds the upper limit temperature tRu 'of the refrigerator compartment, the freezer compartment temperature is sufficiently lower than the lower limit temperature tFi of the freezer compartment and is sufficiently -16- This paper size is applicable to China National Standard (CNS) A4 specification (210X297 mm) ------------- installation-(Please read the precautions on the back before f this page) Thread A7 B7 406174 Five invention descriptions (. Cooling, but it will be cold shirt cooling operation, it becomes the result of Jinlu cooling operation. On the other hand, if it is as above, it will be switched to refrigerating room cooling operation at time ^, so it will not be performed as The aforementioned wasted cold operation. The same purpose is switched to cold again in Ding 2; the east room cooling operation, when the temperature of the cold room reaches the lower limit temperature of the freezing room, it is switched to the cooling room cooling operation. If this control is not performed Even at time T2, wasteful cooling operation will be performed in the vicinity. Furthermore, the above-mentioned refrigerator adjusts the compression capacity of the compressor 46 in step S29. That is, before the temperature tR, tF in the box on the uncooled side reaches the upper limit temperature tRu tFu , Think of the box on the cooling side The internal temperature tF is said to reach the lower limit temperature of 11.1. When the compressor 46 is set, the compression capacity of the compressor 46 is too high, so this should be reduced. Therefore, a cooling operation with better cooling efficiency can be performed. Moreover, according to the uncooled side at this time The difference between the inside temperature tR, tF and the upper limit temperature tRu, tFu of the eRu, eFu, and the difference between the inside temperature tF 'tR and the lower limit temperature tF1, tRl on the cooling side, efl, and 丨 determine how much the compression capacity is reduced. The compression capacity can be controlled to be a proper capacity. In addition, the above-mentioned adjustment is also performed when a predetermined period of time elapses after the cooling operation starts. Therefore, a high temperature load is applied during the cooling operation. (Food, etc.) When the refrigerating compartment 14 or the freezing compartment 22 is put into use, the compression capacity of the compressor 46 can be quickly set to keep the fine internal temperatures tF and tR at an appropriate low temperature. Furthermore, the compressor 46 When the number of revolutions of the operation or the number of revolutions of the blowers 54 and 56 is changed, 'the resonance point of the vibration and noise of the entire refrigerator is avoided. As a result, the noise can be reduced.' Furthermore, for example, the ambient temperature is 15 ° C or less and not performed. Low-load conditions such as door switches are sometimes driven by the compressor 46 with the lowest compression capacity, cold-17 This paper size applies the Chinese National Standard (CNS) from the specifications (21 × 297 mm blanket, Ministry of Economic Affairs, Central Bureau of Standards Printed by employee consumer cooperatives _ 406174_ b 5. Invention description (15) However, the capacity has become excessive. In this case, the refrigerator has to stop the compressor 4 6, so wasteful cooling operation can be reliably avoided. Moreover, when the cooling operation is stopped, Restart is prohibited for a certain period of time. Therefore, the refrigerant pressure can be restarted after the compressor 46 is suctioned and discharged from the compressor side, and the quietness can be improved. In addition, when the compressor 46 is stopped, the cooling operation is performed from the temperature tF in the tank, that is, the upper limit temperature tFu'tRu, so that the temperatures tF and tR in the tank can be reliably lowered. In addition, when the long-term cooling operation is performed, or when a high temperature load (food, etc.) is put into the refrigerator or the freezer compartment 22, the temperature tF, tR in the two or more boxes exceeds the upper limit temperatures tFu, tRu, it will be greatly exceeded. The upper limit temperatures tFu and tRu are cooled. Therefore, the temperature in the box can be kept scarce and the claws can be kept at a proper low temperature. In addition, since the defrosting operation is performed on both the refrigerating evaporator 50 and the refrigerating evaporator 52, it is possible to prevent the cooling efficiency from being lowered due to frost. In particular, since the refrigerating evaporator 50 performs the defrosting operation during the cooling operation of the freezer compartment, the defrosting operation is not hindered by the cooling operation, and the heat loss with the air is also suppressed, so that energy loss can also be suppressed. Furthermore, the above-mentioned refrigerator has a condition that an abnormally high load is put into the cooling side box or the door of the refrigerator is a half-open state or the temperature sensor fails, and the control unit cannot determine that the conditions for switching the cooling operation are in place. In other cases, the cooling operation is forcibly switched if a predetermined time has elapsed. Therefore, it is possible to avoid being left for a long time without cooling the inside of one box. In addition, if an abnormally large load is put in the box or the door of the refrigerator, or the three-way valve 68 or the capillary 70 '72 is faulty, the temperature inside the box may increase significantly.

Description of the invention (16) If the temperature inside the refrigerator tF, tR exceeds the predetermined The forced cooling temperature drives the compressor 46 with the maximum compression capacity, and cools to the upper limit temperatures tFu, tRu. Therefore, even in the case described above, the temperature tF in the tank can be quickly restored to an appropriate low temperature. In addition, even if the compressor 46 with the maximum compression capacity continues to be operated for a predetermined period of time, when the internal temperature tF, Tie does not reach the upper limit temperatures tFU, tRu, it is determined that some abnormality has occurred, the alarm sounds, and at the same time Compression capacity returned to normal. Therefore, an excessive load on the compressor 46 can be avoided, and the reliability can be improved.
