Description of the invention (1) (Technical field to which the invention belongs) The present invention relates to a refrigerator having a plurality of evaporators and a compressor having a compression element. (Conventional technology) Since the ratio of refrigerators to household electricity bills is large, reducing the power consumption of refrigerators in order to reduce household electricity bills has become an important issue. As a technical solution to this problem, a refrigerator having two evaporation benefits' and two compression elements with different evaporation temperatures and connecting the outlets of the two evaporators to the suction passages of the two compression elements, respectively. An example of such a conventional technique is disclosed in Japanese Patent Application Laid-Open No. 5-2 2 3 368. The refrigerator disclosed in the above-mentioned prior art is provided with two compression elements: a freezer evaporator that cools a freezer compartment having a different evaporation temperature and a refrigerator compartment evaporator that cools a refrigerator compartment in parallel, and performs two-stage compression. The suction passage of the low-stage compression element is connected to the evaporator exit of the freezer compartment, while the discharge passage of the low-stage compression element is merged with the evaporator exit of the refrigerator compartment, connected to the suction passage of the high-stage compression element, and the The exhaust passage is connected to the inlet of the condenser. The above-mentioned low-stage compression element is to compress the gas refrigerant flowing from the freezer evaporator from the low pressure of the evaporation pressure level of the freezer evaporator to the intermediate pressure of the refrigerating room evaporator pressure level; The low-stage compression element is compressed to the intermediate pressure of the gas refrigerant, and the gas refrigerant flowing from the evaporator of the refrigerator compartment is compressed from the intermediate pressure to the high pressure of the condenser pressure level.

(Please read the precautions on the back before filling this page) 479122 A7 _____B7_____ V. Description of the Invention (2) In this prior art, compared with the freezer evaporator, it does not change the evaporation temperature The gas refrigerant flowing out of the evaporator of the higher refrigerating compartment is decompressed and compressed from low pressure, but the person who performs compression from intermediate pressure reduces the compression power of the low-stage compression, which greatly reduces the power consumption of the refrigerator. . Further, as described above, a refrigerator having an evaporator in the freezing compartment and a refrigerating compartment, respectively, is compared with a refrigerator having an evaporator for cooling both the freezing compartment and the refrigerating compartment by forced circulation of air conditioning. Increasing the evaporation temperature of the evaporator of the refrigerating compartment, therefore, it is possible to increase the temperature of the discharged cold air to the refrigerating compartment while maintaining a high temperature. (Problems to be solved by the invention) In general, the temperature of the freezer compartment of a refrigerator is -1 ° C or lower. On the other hand, the temperature of the refrigerator compartment is required to be 5 t or less higher than 0 ° C. The conventional technology disclosed in Japanese Patent Application Laid-Open No. 5-2 2 3 3 6 5 mentioned above uses two evaporators having two compression elements and different evaporation temperatures to simultaneously cool the freezer and refrigerator compartments. Strive for a substantial reduction in power consumption. However, in the simultaneous cooling of the freezing compartment and the refrigerating compartment according to the above-mentioned conventional technology, since the freezing compartment is cooled even if the temperature of the refrigerating compartment is lower than a predetermined value and the freezing compartment temperature is higher than a predetermined value, the temperature of the refrigerating compartment is cooled to more than necessary. Problems, and there is no consideration for the adverse effects of storage in the refrigerated room. In order to solve such a problem, an electric heater in a warming refrigerating room is provided without freezing food in the refrigerating room, which causes a problem of increasing power consumption.

The low-stage compression element 11 of the compressor 10 is to compress the gaseous refrigerant from the freezer evaporator 2 2 from the low pressure of the evaporation pressure level of the freezer evaporator 2 2 (the lowest pressure of the refrigeration cycle) to the refrigerator compartment. In the middle of the evaporation pressure level of the evaporator 25, the high-stage compression element 12 is compressed to the intermediate pressure by the low-stage compression element 11 and the gas refrigerant cooled by the intercooler 27 is communicated with The gas refrigerant in the refrigerator compartment evaporator 25 is compressed from the intermediate pressure to the high pressure of the condensation pressure level of the condenser 13 (the highest pressure of the refrigeration cycle).

Description of the invention (21) The amount of push-down of the low-end compression element 11 and the high-end compression element 12 is set to be the same or approximately the same. The reason is to The following. The evaporation pressure of the refrigerating compartment evaporator 25 is higher than that of the freezing compartment evaporator 22, and the suction gas specific volume of the high-stage compression element 12 becomes about half of the suction gas specific volume of the low-stage compression element 11, but Where the refrigerating cycle room and the refrigerating room must be approximately equal in freezing capacity, the refrigerant mass flow rate of the high-stage compression element 12 is approximately twice the refrigerant mass flow rate of the low-stage compression element 1 1, and each compression element 1 1 The cold medium volume of the suction gas of 12 is about the same. The actual pushing amount is set by the required freezing capacity of the freezing compartment and the refrigerating compartment, and the compression element 11 and 12, respectively, the predetermined suction gas pressure, temperature conditions and the like. When the push-opening amounts of the two compression elements 11 and 12 are the same, a part of the parts can be shared, the number of parts can be reduced, and the cost can be reduced. The internal pressure of the sealed container 40 of the compressor 10 becomes the pressure of the suction gas of the high-stage compression element, which is also the intermediate pressure (the evaporation pressure level of the refrigerator compartment evaporator 25). Fig. 8 shows the pressure difference between the compression pressure in the compression chamber and the pressure in the closed container during the rotation of the compressor 10 when the compressor 10 performs two-stage compression.

Description of Invention (22). From the figure, (b) In the case of the intermediate compression container, the smaller pressure difference per rotation is effective in reducing the amount of leakage gas according to the pressure difference in the compression process, which can improve the efficiency of the two stages of compression of the compressor. The oil supply to the action chamber (suction chamber, compression chamber) for the compression element of the sealed container is the oil leaked into the action chamber through the pressure difference between the sealed container and the action chamber and the oil provided in the auxiliary bearing 4 8 Oil sacs, and are performed by oil contained in the inhaled gas. In addition, the oil supply to the operation chamber for sealing the operation chamber of the highly compressed element is performed by the oil bag 63 provided in the main bearing 4 4 by the oil contained in the inhaled gas. The intercooler 27 cools the exhaust gas of the low-end compression element, and reduces the effect of the temperature of the suction gas of the high-end compression element. Therefore, the theoretical insulation compression work per unit volume of the high-end compression element can be reduced. And reduce compression power. When the freezer is cooled separately, the first solenoid valve 2 3 and the second solenoid valve 26 are closed together. Since the solenoid valve 23 is closed, the refrigerant flow system for the refrigerator evaporator 25 is blocked, and the refrigerant system flows only toward the compression element evaporator 2 2. At this time, the low-stage compression element 11 of the compressor 10 is a gas refrigerant sucked into the outlet of the evaporator 22 of the freezer to perform the compression effect. In the path connected to the discharge path 1 1 b of the low-stage compression element 1 1, one of the solenoid valves 2 6 is opened and closed, so it is higher than the other side of the discharge-side check valve 1 3 b. The pressure of the gas refrigerant in the discharge path 1 2 b of the compression element 1 2 is relatively high, and the gas refrigerant of the low compression element 1 1 is compressed, and then passes through the check valve 1 3 b.

Description of Invention (23). On the other hand, when the solenoid valves 2 3 and 2 6 are closed, the refrigerating compartment evaporator 25 connected to the suction passage 12 a and the intercooler 2 7 are not supplied with refrigerant. As a result, the pressure of the gas refrigerant in the suction passage 1 2 a of the high-stage compression element 12 is gradually lowered, and the pressure of the gas refrigerant in the suction passage 1 1 a of the low-stage compression element 11 is reduced. As a result, the check valve 1 a on the suction side is opened, and the gas refrigerant on the suction passage 12 a side of the low-stage compression element 11 1 flows into the compression element 12 a side of the high-pressure compression element 12. The pressure of the gas refrigerant in the refrigerating compartment evaporator 2 5 and the intercooler 27 is the same as the pressure of the gas refrigerant in the suction passage 1 2 a. The evaporation pressure level of the freezing compartment evaporator 2 2 is the same, but the refrigerating compartment evaporator 2 5 The temperature is approximately equal to the temperature of the air in the refrigerator compartment 3, and the temperature of the intercooler 27 is approximately equal to the temperature of the bottom air of the refrigerator body 1, which is higher than the evaporation temperature of the freezer compartment evaporator 22. Therefore, the gas refrigerant in the suction passage 12a can prevent the evaporator 25 and the intermediate cooler 27 from condensing and staying in the refrigerator compartment. The valve 2 3 is arranged between the branch portion of the refrigerant pipe provided between the evaporator and the condenser and the evaporator. The valve 2 6 is arranged between the intercooler 27 and the discharge passage 1 1 b of the compression element 11. With such a configuration, the amount of refrigerant remaining in the evaporator 25 or the cooler 27 can be reduced when the cooling operation of the refrigerating compartment is performed separately, and high operation efficiency can be maintained. At this time, the two compression elements 11 and 12 are respectively from the evaporation pressure level of the evaporator 22 of the freezer evaporator 22, and the compression effect is performed in parallel until the condensation pressure level of the condenser 20 is reached. Therefore, the paper size of the compressor 10 is applicable to the Chinese National Standard (CNS) A4 specification (210 X 297 mm) " 2ύ " (Please read the precautions on the back before filling this page) Install tr ---- ----- Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs 479122 A7 B7___ V. Two compression elements of the invention description (24) 1 1, 12 2, condenser 2 0, first capillary 21, freezing chamber evaporation The refrigerating compartment formed by the device 22 is separately cooled and refrigerated. Further, the condenser fan 30 and the freezer evaporator fan 31 are operated, and the refrigerator compartment evaporator fan 32 is stopped. Thus, only the cooling of the freezing compartment 2 is performed. At this time, the internal pressure of the hermetic container 40 of the compressor 10 becomes the pressure of the suction gas of the high-level compression element, that is, it becomes a low pressure (the evaporation pressure level of the freezer evaporator 22). Fig. 9 shows the pressure difference between the pressure of the compression chamber and the pressure in the closed container during the rotation of one of the compression elements when the compressor 10 performs single-stage compression, in the case of (a) a high-pressure closed container and (b) a low-pressure closed container. The solid line indicates the pressure in the compression chamber, the dotted line indicates the pressure in the closed vessel, and the oblique line indicates the pressure difference. Under these conditions as the refrigerant R134a, the evaporation temperature of the freezer evaporator is _26 ° C, and the condensation temperature of the condenser is 3 2 ° C. As can be seen from the figure, (b) in the case of a low-pressure closed container, the pressure difference per rotation is small, which is effective in reducing the amount of leakage gas according to the pressure difference in the compression process, and can improve the efficiency of the compressor in a single stage of compression . In order to seal the action chambers (suction chambers, compression chambers) of the two compression elements, the oil supply to the action chambers is provided by the oil sacs located in the above-mentioned auxiliary bearings 4 8 and main bearings 4 4 and the oil contained in the suction gas.

With the above-mentioned structure and operation control, the heating of the refrigerator to prevent freezing of food in the refrigerator compartment is not required. The temperature of the refrigerator compartment can be lower than-18 ° C, and the temperature of the refrigerator compartment can be higher than 0 ° C and lower than 5 ° C. , Can properly maintain the temperature of the freezer and refrigerator. In addition, during the simultaneous cooling operation of the refrigerating compartment and the refrigerating compartment, the gas refrigerant from the refrigerating compartment evaporator is depressurized to a low pressure of the evaporation pressure of the freezing compartment evaporator. Therefore, compression is not performed from the low pressure. Compression is performed from the middle pressure of the evaporation pressure level of the refrigerator compartment evaporator, so the compression power can be reduced, and the power consumption of the refrigerator can be greatly reduced. In addition, since the compressor has two compression elements, two stages of compression are implemented during the simultaneous cooling operation of the freezing compartment and the refrigerating compartment. Therefore, the pressure difference between the compression chamber and the suction chamber of each compression element can be reduced, and the compression is reduced. The amount of leakage gas in the process is effective, which can improve the efficiency of the compressor and the efficiency of the refrigerator. In addition, since the two compression elements constituting the compressor can be compressed in parallel when the freezer is separately cooled, the amount of push-opening used to cool the freezer is twice that of the freezer when the refrigerator is cooled and operated at the same time.

Description of the invention (28) Compared with a refrigerator with an evaporator, which cools the freezer compartment and the refrigerator compartment by air-conditioning, it can improve the refrigerator compartment. The evaporation temperature of the evaporator to increase the temperature of the cold air discharged from the refrigerating compartment can maintain high humidity, so the food in the refrigerating compartment can be kept in a good state. In addition, since the amount of frosting in the evaporator of the refrigerator compartment is also reduced, the defrosting cycle of the electric heater can be extended, which is effective in reducing power consumption. In addition, since the cold air systems of the freezer compartment and the refrigerator compartment are completely separated, the odor between the freezer compartment and the refrigerator compartment can be prevented from moving. In addition, since the suction passage connecting the compression element and the opening in the hermetic container of the compressor are provided, the pressure in the hermetic container is reduced to a low pressure when the compressor is compressed in one stage, and the pressure in the hermetic container is compressed in the two stages of compression. The pressure becomes intermediate pressure. Therefore, the pressure difference between the pressure of each rotating compression chamber and the closed container is small, and it is effective to reduce the amount of leakage gas according to the pressure difference in the compression process, and the efficiency of the compressor can be improved. Further, since the pressure in the closed container of the compressor is reduced to a low pressure or an intermediate pressure, the amount of the refrigerant dissolved in the lubricating oil can be reduced, and the correspondence with the hydrocarbon-based refrigerant of the flammable refrigerant becomes easy. In addition, since the check valve is arranged in a closed container, the piping around the compressor can be made compact and refined.

In addition, the condensing benefit fan 30, the freezing compartment evaporator fan 31, and the refrigerating compartment evaporator fan 32 are operated. Compressor 1 0 > The low-stage compression element 1 1 is a low-pressure (minimum pressure of the refrigeration cycle) that compresses the gas refrigerant from the freezer evaporator 2 2 from the evaporation pressure level of the freezer evaporator 2 2 to the refrigeration. The high-stage compression element 1 2 will be compressed to the intermediate pressure by the low-stage compression element 1 1 to the intermediate pressure of the evaporation pressure level of the chamber evaporator 25, and the gas cooled by the intermediate cooler 27 will be The refrigerant, together with the gas refrigerant from the refrigerating compartment evaporator 25, is compressed from the intermediate pressure to the high pressure of the condensation pressure level of the condenser 13 (the highest pressure of the refrigeration cycle).

During the freezer cooling operation alone, as shown in FIG. 12, the solenoid valves 70a, 70b, 71a, and 71b are opened, and the solenoid valves 2 and 3 are closed. At this time, the two compression elements 1 1, 1 2 series are connected in parallel.

In addition, because the solenoid valve 26 is closed, the exhaust gas system of the low-level compression element 1 1 passes through the open solenoid valve 7 1 b, and the paper size of the high-end section applies the Chinese National Standard (CNS) A4 specification (210 X 297 mm). ) --- I--L ------------ (Please read the note on the back?

Description of the invention (31) The exhaust gas from the compression element 12 merges and enters the condenser 20. Thereby, the freezing chamber composed of two compression elements 1 1 ′ 12, the condenser 20, the first capillary tube 21, and the freezing chamber evaporator 22 are separately cooled and refrigerated. In addition, the condenser fan 30 and the freezing compartment evaporator fan 3 1 are operated, and the refrigerating compartment evaporator fan 32 is stopped. Thereby, a separate cooling operation of the freezing chamber is performed. In the cooling operation of the refrigerator compartment alone, as shown in Fig. 12, the solenoid valves 2 3, 7 1 a, 7 1 b are opened, and the solenoid valves 2 6, 7 0 a, 7 0 b are closed. At this time, the two compression elements 11 and 12 are connected in parallel. Since the solenoid valve 23 is opened and the solenoid valve 7 0 a is closed, the refrigerant is supplied to the refrigerating compartment evaporator 25 and the refrigerant is not supplied to the freezer evaporator 2 2. As the solenoid valve 7 0 b is closed, the low-stage compression element 1 1 is sucked through the open solenoid valve 7 1 a and compresses the body refrigerant from the refrigerator compartment evaporator 2 5. Since the solenoid valve 26 is closed, the exhaust gas system of the low-stage compression element 11 passes through the open solenoid valve 7 1 b, merges with the exhaust gas of the high-stage compression element 12, and enters the condenser 20. As a result, two compression elements 11, 12, condenser 20, and second capillary tube 2 4 • refrigerator compartment evaporator 25 constitute a separate cooling and freezing cycle. Further, the condenser fan 30 and the refrigerating compartment evaporator fan 32 are operated, and the freezing compartment evaporator fan 31 is stopped. Thereby, a separate cooling operation of the refrigerator compartment is performed. In addition, the pressure of the gas refrigerant in the intercooler 27 is the same as the pressure of the gas refrigerant in the suction passage 12a, and the evaporation pressure of the refrigerating compartment evaporator 25 is at a level, but because the temperature of the intercooler 27 is The paper size of the refrigerator body applies the Chinese National Standard (CNS) A4 specification (210 X 297 mm) _ 34----------- ^ ----- ^ ---- ^ ---- ----- (Please read the notes on the back before filling out this page) 479122 Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs A7 B7 V. Description of the invention (32) The air temperature at the bottom is approximately equal to the evaporation temperature of the refrigerator compartment Higher. Therefore, the problem that the gas refrigerant condenses and stays in the intercooler 27 can be prevented. In addition, since the solenoid valves 70a and 70b are closed, the gas refrigerant in the cyclic refrigeration cycle is cooled in the freezer evaporator 22, which can prevent the problem of condensation and retention. In this embodiment, since the freezer compartment can be switched for simultaneous cooling operation, the freezer compartment can be operated in separate cooling operation, and the refrigerator compartment can be operated in separate cooling operation. Therefore, as in the first embodiment, heating for preventing freezing of food in the refrigerator compartment is not required. For example, the temperature of the freezer compartment can be lower than -18 ° C, and the temperature of the refrigerator compartment can be higher than 0 ° C and lower than 5 ° C. The temperature of the freezer compartment and the refrigerator compartment can be appropriately maintained. In addition, compared with the first embodiment, the separate cooling operation of the refrigerating compartment is also possible. Therefore, when only the refrigerating compartment needs to be cooled, it is not necessary to cool the freezing compartment at the same time as in the first embodiment. Only the cooling compartment can be cooled. The refrigerating compartment can prevent the remaining cooling of the freezing compartment. In addition, during the simultaneous cooling operation of the refrigerating compartment and the refrigerating compartment, the gas refrigerant from the refrigerating compartment evaporator is depressurized to a low pressure of the evaporation pressure of the freezing compartment evaporator. Therefore, compression is not performed from the low pressure. Compression is performed from the middle pressure of the evaporation pressure level of the refrigerator compartment evaporator, so the compression power can be reduced, and the power consumption of the refrigerator can be greatly reduced. In addition, since the compressor has two compression elements, two stages of compression are implemented during the simultaneous cooling operation of the freezing compartment and the refrigerating compartment. Therefore, the pressure difference between the compression chamber and the suction chamber of each compression element can be reduced, and the compression is reduced. The amount of leakage gas in the process is effective, which can improve the efficiency of the compressor and increase the size of the electric paper.

Description of the invention ( 33) Efficiency of the refrigerator. In addition, since the two compression elements of the compressor can be compressed in parallel when the freezer or refrigerating room is separately cooled and operated, the amount of push-opening used for cooling the freezer or refrigerating room becomes the same as that during the simultaneous cooling operation of the freezer or refrigerating room. It can double the freezing capacity of the freezer or refrigerator. In addition, a refrigerator having an evaporator in the freezing compartment and a refrigerating compartment, respectively, can improve the efficiency of the refrigerating compartment evaporator in comparison with a refrigerator in which both the freezing compartment and the refrigerating compartment are cooled by air circulation. The evaporation temperature can increase the temperature of the discharged cold air to the refrigerating compartment and can maintain high humidity, so the food in the refrigerating compartment can be kept in a good state. In addition, since the amount of frosting in the evaporator of the refrigerator compartment is also reduced, the defrosting cycle of the electric heater can be extended, which is effective in reducing power consumption. In addition, since the cold air systems of the freezer compartment and the refrigerator compartment are completely separated, the odor between the freezer compartment and the refrigerator compartment can be prevented from moving. The direct object of the present invention is a refrigerator, but it can also be applied to a refrigerating and air-conditioning apparatus other than a refrigerator having a plurality of evaporators having different evaporation temperatures and capable of cooling a plurality of rooms. In addition, the refrigerator of the first embodiment has a structure in which the refrigerator body (box) is integrated into a freezer compartment and a refrigerating compartment as shown in FIG. 2. However, the present invention is of course applicable to each of the freezer compartment and the refrigerating compartment. The box is a refrigerator composed of a plurality of boxes. Also, in the first embodiment, it is explained that a two-cylinder rotary compressor in which a roller portion and a vane portion are integrated as a compressor. However, the present invention uses another compressor having two or more compression elements such as a light portion. Applies to Chinese National Standard (CNS) A4 specifications (210 X 297 public love) and paper size. ---------- ^-Order --------- (Please read the note on the back first Please fill out this page again) Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 479122 A7 B7____ V.
