The main body 10 may be provided with a discharge port 44 through which air for performing an air conditioning function is discharged.

Since the air discharged from the discharge port 44 may be a cold air at a low temperature, the temperature may be lower than the ambient air. That is, since the air discharged from the discharge port 44 is relatively heavy compared to the surrounding air, it is preferable that the discharge port 44 is formed on the upper side of the main body 10. However, the position of the discharge port 44 is not limited to this. For example, the discharge port 44 may be located on the side surface of the main body 10. [

The discharge port 44 may be formed on the upper side of the door 80. The discharge port 44 may be formed to face the front surface of the main body 10, but is not limited thereto. In addition, the discharge port 44 may have a rectangular cross section.

Air can be sucked into the main body 10 through the suction port 45 and discharged to the discharge port 44 when the air conditioner system of the refrigerator 1 is operated.

FIG. 2 is an overall structural view illustrating an internal structure of a refrigerator according to an embodiment of the present invention, and FIG. 3 is a view for explaining the structure of a heat pipe.

At this time, the partition wall may be a heat insulating wall, whereby the temperature of each of the storage unit 20, the air conditioning unit 40, and the machine room 50 can be independently maintained.

The air conditioning part 40 may be located on the upper side of the main body 10, but is not limited thereto. The air conditioning part (40) can be partitioned into a storage part (20) and a heat insulating partition wall.

Food may be stored or stored in the storage 20. The storage unit 20 may include a freezer compartment 21 and a refrigerating compartment 22. The internal temperature of the freezing compartment 21 may be lower than the internal temperature of the refrigerating compartment 22. More specifically, the internal temperature of the freezing compartment 21 may be below -15 캜. The internal temperature of the refrigerating compartment 22 may be an image and is preferably about 3 to 5 캜.

The freezing compartment 21 and the refrigerating compartment 22 may be partitioned by a heat insulating partition wall. At least one hole (not shown) through which air can pass may be formed in the heat insulating partition wall for partitioning the freezing compartment 21 and the refrigerating compartment 22. The holes may be selectively openable and closable. Thus, the cold air in the freezing chamber 21 and the refrigerating chamber 22 can be mixed, and the temperature inside the refrigerating chamber 22 can be further lowered by the cooling air in the freezing chamber 21.

A temperature sensor (not shown) may be provided in the freezer compartment 21 and the refrigerating compartment 22, respectively.

The freezing compartment 21 may be located at one side of the storage unit 20 and the refrigerating compartment 22 may be located at the other side of the storage unit 20. The freezing compartment 21 may be located above the refrigerating compartment 22, but is not limited thereto. For example, the freezing chamber 21 may be located on the left or right side of the refrigerating chamber 22.

On the rear side of the storage unit 20, a barrier 60 may be provided. That is, the storage unit 20 can be positioned in front of the barrier 60. It is preferable that the barrier 60 is disposed as close as possible to the back of the main body 10 when the size of the main body 10 is constant since the larger the inner space of the storage unit 20 is,

At least one cold air discharge opening (61, 62) may be formed in the barrier (60). For example, the barrier 60 may be provided with a first cool air discharge port 61 for discharging cool air to the freezing chamber 21 and a second cool air discharge port 62 for discharging cool air to the refrigerating chamber 22 .

The first cool air discharge port 61 may be formed in a portion corresponding to the freezing chamber 21 in the barrier 60 and the second cool air discharge port 62 may be formed in a portion corresponding to the refrigerating chamber 22 in the barrier 60 .

At least one evaporator (211, 221) and evaporation fans (212, 222) may be installed behind the barrier (60). For example, the first evaporator 211 and the first evaporator fan 212 can be positioned behind the portion corresponding to the freezer compartment 21 in the barrier 60, and the first evaporator 211 and the first evaporator fan 212 can be located in the freezer compartment 22 And a second evaporator 221 and a second evaporation fan 222 may be positioned behind the corresponding portion.

The first evaporation fan 212 can blow air that has been heat-exchanged in the first evaporator 211 to the freezing chamber 21 through the first cooling air discharge opening 61. The second evaporation fan 222 can blow air that has been heat-exchanged in the second evaporator 221 to the refrigerating chamber 22 through the second air discharge opening 62. That is, the first evaporator 211 may be a freezer compartment evaporator for cooling the freezer compartment 21, and the second evaporator 221 may be a refrigerator compartment evaporator for cooling the refrigerating compartment 22.

The cooling load required by the first evaporator 211 may be larger than the cooling load required by the second evaporator 221 since the temperature of the freezer compartment 21 should be maintained lower than the temperature of the refrigerating compartment 22. [ Therefore, the flow rates of the refrigerant flowing into the first evaporator 211 and the second evaporator 221 may be different from each other, and the flow rate of the refrigerant can be controlled by the main valve device 56.

It is preferable that the evaporation fans 212 and 222 are disposed between the evaporators 211 and 221 and the cold air discharge ports 61 and 62 but the evaporation fans 212 and 222 are disposed behind the evaporators 211 and 221 It is possible.

An accumulator (not shown) for preventing liquid refrigerant from being introduced into the compressor 51 may be installed in the suction flow path 19.

The first connection passage 16 can connect the compression section 14 and a heat storage heat exchange section 57, which will be described later. In more detail, the first connection passage 16 may connect the sub-valve device 58 and the heat exchanger 570. The first connection passage 16 can guide the refrigerant discharged from the sub valve device 58 to the heat exchanger 570.

The sub valve device 58 can regulate the direction and amount of flow of the refrigerant in order to supply the refrigerant compressed in the compressor 51 to the heat storage heat exchanger 57 and / or the condenser 52.

Hereinafter, the refrigeration and / or refrigeration system will be described. The refrigeration and / or refrigeration system may refer to a refrigeration cycle for refrigeration and / or refrigeration.

As described above, the refrigerant compressed in the compression section 14 can be introduced into the condenser 52 through the condenser inlet flow path 54.

In the condenser (52), the refrigerant compressed in the compressor (51) can be condensed. The condenser 52 may be connected to the compression unit 14 through the condenser inlet flow path 54. More specifically, the condenser 52 may be connected to the sub-valve device 58 by a condenser inlet flow path 54. [ The refrigerant introduced into the condenser 52 through the condenser inlet flow path 54 in the sub valve device 58 can be heat-exchanged with the air inside the mechanical chamber 50 and condensed.

The condenser 52 may be connected to the condenser outlet flow path 55. The refrigerant condensed in the condenser 52 may flow into the condenser outlet flow path 55.

The condensing fan 53 can blow the air exchanged with the refrigerant in the condenser 52 to the outside of the main body 10 through a passage (not shown) formed on the back surface of the main body 10. [ The condensing fan (53) can be disposed between the passage and the condensing fan (53). It is also possible that the condenser 52 is disposed between the condensing fan 53 and the communicating hole.

The main valve device 56 may be connected to a condenser outflow passage 55 and at least one refrigerant passage 214, 224. At this time, the refrigerant flow paths 214 and 224 may correspond to the evaporators 211 and 221, respectively.

The condenser outflow channel 55 may connect the condenser 52 and the main valve unit 56. The refrigerant condensed in the condenser 52 may flow into the main valve device 56 through the condenser outlet flow path 55.

The main valve device 56 may adjust the flow direction of the refrigerant to supply the refrigerant condensed in the condenser 52 to the first evaporator 211 and the second evaporator 221. The amount of the refrigerant flowing into the first evaporator 211 and the second evaporator 221 may be changed under the control of the main valve device 56. [ The main valve device 56 may include a three way valve or a four way valve.

At least one of the refrigerant passages 214 and 224 may connect the main valve device 56 and at least one of the evaporators 221 and 221.

At least one expansion mechanism (213, 223) may be provided in the body (10). The expansion mechanisms 213 and 223 are preferably disposed within the machine room 50.

The plurality of expansion mechanisms 213 and 223 may be provided corresponding to the plurality of evaporators 211 and 221, respectively. For example, the first evaporator 211 and the second evaporator 221 may correspond to the first expansion mechanism 213 and the second expansion mechanism 223, respectively. The first expansion mechanism 213 may be provided in the first refrigerant passage 214 and the second expansion mechanism 223 may be provided in the second refrigerant passage 224. [

The refrigerant flowing into the main valve device 56 through the condenser outlet flow path 55 may flow into the refrigerant flow paths 214 and 224. The refrigerant can expand through the expansion mechanisms 213, 223 on the refrigerant flow paths 214, 224. The refrigerant throttled in the expansion mechanisms (213, 223) can be evaporated in the evaporators (211, 221).

As described above, the evaporation fans 212 and 222 can blow the air that has been heat-exchanged with the refrigerant in the evaporators 211 and 221 to the inside of the storage unit 20 through the cold air discharge ports 61 and 62. Thus, refrigeration and / or refrigeration of the storage unit 20 may be possible.

The evaporators 211 and 221 may be connected to the suction flow path 19. The refrigerant heat-exchanged with the air in the evaporators 211 and 221 flows into the suction passage 19 and can be sucked into the compressor 51. Whereby refrigeration and / or refrigeration systems can be constructed.

Hereinafter, the configuration of the air conditioning system will be described.

As described above, the compression section 14 may be connected to the heat storage heat exchanging section 57 through the first connection passage 16. More specifically, the compressor 51 and the sub valve device 57 may be connected to the discharge passage 15, and the sub valve device 57 and the heat exchanger 570 may be connected to the first connection passage 16 .

The heat storage heat exchanger 57 may include a heat exchanger 570 and a heat storage material 571. A heat pipe 572 may be connected to the heat storage heat exchanging part 57.

The heat storage material 571 may cover the heat exchanger 570. When the heat storage material 571 covers the entire heat exchanger 570, the contact area between the heat exchanger 570 and the heat storage material 571 is maximized and the heat exchange efficiency between the refrigerant passing through the heat exchanger 570 and the heat storage material 5710 Can rise.

The heat storage heat exchanging part (57) can be disposed inside the main body (10). Preferably, the heat storage heat exchanging part 57 may be disposed in the air conditioning part 40. The heat storage heat exchanging part (57) can be disposed in the receiving part (41) of the air conditioning part (40).

The refrigerant flowing into the heat exchanger 570 can be heat-exchanged with the heat storage material 571. In more detail, the heat exchanger 570 may serve as a condenser for condensing the refrigerant introduced therein.

The heat exchanger 570 may be connected to the first connection passage 16 and the second connection passage 17. The refrigerant flowing into the heat exchanger 570 through the first connection passage 16 is condensed in the heat exchanger 570 and flows into the second connection passage 17.

The heat storage material 571 can be heat-exchanged with the refrigerant in the heat exchanger 570. The heat storage material 571 may include a phase change material (PCM). Since the amount of heat required to phase-change the material is very large, the heat storage material 571 can efficiently store large amounts of heat, and the air conditioning system can satisfy a relatively large cooling load.

In the heat exchanger (570), the refrigerant condenses to dissipate the heat of condensation, and the heat storage material (571) exchanges heat with the refrigerant to store the condensation heat. However, since there is a limit to the amount of heat that can be stored in the heat storage material 571, heat storage of the heat storage material 571 is required.

The heat pipe 572 connected to the heat storage material 571 can perform heat dissipation of the heat storage heat exchange portion 57. More specifically, the heat pipe 572 can dissipate heat accumulated in the heat storage material 571. [

The heat pipe 572 may mean a heat transfer pipe for efficiently transferring heat. The interior of the heat pipe 572 may be depressurized to receive a working fluid in a liquid state. At this time, when one end of the heat pipe 572 is heated, the working fluid in a liquid state stored at one end may be evaporated and vaporized by the vapor. The one end may be a heating part 573.

The vaporized vapor may flow from the one end to the other opposite end by the density difference. And the other end may be the heat dissipating portion 574. In the heat radiating portion 574, the steam can be condensed into liquid by heat, and the working fluid in the liquid state flows into the heating portion 573 of the heat pipe 572 through the wick 575, wik by capillary phenomenon You can come back. The inner wall of the wick 575 may be porous allowing vapor to pass therethrough.

The working fluid circulates inside the heat pipe 572 according to the above-described process and can perform heat dissipation.

The heat pipe 572 may be connected to the heat storage heat exchanger 57 and a part of the heat pipe 572 may be located outside the body 10. [ More specifically, the heat pipe may be connected to the heat storage material 571, and a part of the heat pipe may be located at the rear of the body 10.

One end of the heat pipe 572 is connected to the heat storage heat exchanger 57 and the other end of the heat pipe 572 located on the opposite side of the heat pipe 572 may be located behind the main body 10. One end connected to the heat storage heat exchanging part 57 may be the heating part 573 and the other end located outside the main body 10 may be the heat dissipating part 574.

Part of the heat pipe 572 may be buried in the heat storage material 571 and some of the portions not buried in the heat storage material 571 may be located outside the body 10. [

The portion of the heat pipe 572 buried in the heat storage material 571 may denote the heating portion 573 and the portion of the heat pipe 572 located outside the body 10 may denote the heat dissipation portion 574. [ have.

The amount of heat accumulated in the heat storage material 571 can be used to heat the heating portion 573 of the heat pipe 572 and the amount of heat can be reduced by the working fluid inside the heat pipe 572, The heat can be dissipated from the external heat dissipating portion 574.

A plurality of heat pipes 572 may be provided. The greater the number of heat pipes 572, the more heat can be generated.

The heat radiation by the heat pipe 572 is advantageous in that the heat of the heat storage heat exchanger 57 can be dissipated without any additional power. That is, consumption power can be minimized.

Also, since the heat radiation can be performed simultaneously with the operation of the air conditioning system, there is an advantage that cooling and heat radiation can be performed simultaneously without a separate heat radiation mode.

Further, the heat of condensation can be dissipated by the heat pipe 572, so that there is an advantage that heat can be dissipated without a separate outdoor unit.

On the other hand, the refrigerant condensed in the heat accumulation heat exchanging part (57) can flow to the air conditioning expansion mechanism (59) through the second connection flow path (17).

The air conditioning expansion mechanism (59) can expand the refrigerant flowing into the second connection passage (17). That is, the refrigerant guided to the second connection flow path 17 can expand through the air conditioning expansion mechanism 59. The expanded refrigerant may be in a state where the liquid refrigerant and the gaseous refrigerant coexist.

The air conditioning expansion mechanism (59) can be connected to the heat storage heat exchanger (57) by the second connection passage (17). That is, the second connection passage 17 can connect the heat storage heat exchanger 57 with the air conditioning expansion mechanism 59. More specifically, the second connection passage 17 can connect the air conditioner expansion mechanism 59 with the heat exchanger 570.

The air conditioning expansion mechanism 59 may be provided inside the main body 10 and may be disposed inside the air conditioning unit 40 like the heat storage heat exchanger 57.

The air conditioning duct (18) can connect the air conditioning expansion mechanism (59) and the air conditioning heat exchanger (46). The refrigerant throttled in the air conditioning expansion mechanism (59) can be flowed to the air conditioning heat exchanger (46) located inside the air conditioning part (40) through the air conditioning flow path (18).

The refrigerant flowing into the air conditioning heat exchanger (46) can be heat-exchanged with air. More specifically, the air conditioning heat exchanger (46) may serve as an evaporator for evaporating the refrigerant.

The air conditioning heat exchanger (46) may be disposed inside the air conditioning part (40). More specifically, the air conditioning heat exchanger 46 may be located in the receiving portion 41.

The blower port 47 may be disposed inside the air conditioning part 40. More specifically, the blower orifice 47 may be disposed in the receiving portion 41. The blower port (47) can be arranged to face the air conditioning heat exchanger (46).

The blower port (47) can be disposed between the air conditioning heat exchanger (46) and the air inlet (45). It is also possible that the blower port 47 is disposed between the air conditioning heat exchanger 46 and the discharge port 44.

The blower port 47 sucks the air outside the main body 10 through the suction port 45 and exchanges heat with the air conditioning heat exchanger 46 to blow the cooled air toward the discharge port 44.

The suction passage (19) can connect the air conditioning heat exchanger (46) and the compression section (14). More specifically, the suction passage 19 can connect the air conditioning heat exchanger 46 and the compressor 51. [ The refrigerant evaporated in the air conditioning heat exchanger (46) can be sucked into the compressor (51) through the suction passage (19).

Hereinafter, the operation of the air conditioning system will be described.

The air conditioning system of the refrigerator 1 according to the present embodiment can constitute a cooling cycle for cooling.

The refrigerant compressed in the compression section 14 can flow to the heat storage heat exchange section 57 inside the air conditioning section 40 through the first connection flow passage 16. In more detail, the gaseous refrigerant of high temperature and high pressure compressed by the compressor 51 may be discharged to the discharge passage 15 and flow to the sub valve device 58. The control unit can control the sub valve device 58 so that the refrigerant introduced through the discharge path 15 is divided into the first connection path 16 and the condenser inflow path 54.

The refrigerant flowing into the heat exchanger 570 of the heat accumulating heat exchanger 57 through the first connection passage 16 can be condensed by heat exchange with the heat accumulating material 571 in the heat exchanger 570. Therefore, heat discharged from the refrigerant can be accumulated in the heat storage material 571. [

The heat radiation of the heat storage material 571 through the heat pipe 572 can be performed simultaneously with the heat storage of the heat storage material 571. [ Therefore, the temperature rising speed of the heat storage material 571 can be relatively slowed, and the cooling operation time can be prolonged.

The refrigerant condensed in the heat storage heat exchanging part (57) can be flowed to the air conditioning expansion mechanism (59) through the second connection flow path (17). The refrigerant passes through the air conditioning expansion mechanism (59) and can be expanded.

The refrigerant expanded in the air conditioning expansion mechanism (59) can be guided to the air conditioning heat exchanger (46) through the air conditioning duct (18). In the air conditioning heat exchanger (46), the refrigerant can be evaporated by heat exchange with air.

At this time, the blower port (47) can blow air cooled by the heat exchange with the refrigerant in the air conditioning heat exchanger (46) to the discharge port (44). More specifically, the air sucked into the suction port 45 by the blower port 47 can be cooled by heat exchange with the air conditioning heat exchanger 46 in the accommodating portion 41, and the intermediate portion 43 and the duct portion 42 in that order, and can be discharged to the discharge port 44. [ Thus, the refrigerator 1 according to the present embodiment can perform a cooling function for lowering the indoor temperature.

The refrigerant vaporized in the air conditioning heat exchanger (46) can flow into the suction passage (19). The refrigerant vaporized in the air conditioning heat exchanger 46 may be combined with the refrigerant which is evaporated in the evaporators 211 and 221 and flowed into the suction passage 19 in the course of passing through the suction passage 19. [

The refrigerant that has flowed through the suction passage 19 to the compression section 14 can be sucked into the compressor 15 and can repeat the above-described processes to form a cooling cycle. Thus, the air conditioning system of the refrigerator 1 according to the present embodiment can be configured.

On the other hand, when the air conditioning system is not operating, the refrigerant does not circulate and only the heat radiation by the heat pipe 572 can be performed.

FIG. 4 is a view showing the flow of the refrigerant during the single operation of the refrigerating and freezing system.

Hereinafter, the same contents as those described above will be omitted and differences will be mainly described.

4, when the air conditioning system is stopped and the refrigeration and / or refrigeration system is operated alone, all the refrigerant introduced through the discharge passage 15 flows into the condenser inflow passage 54, Respectively. In this case, the passage of the sub valve device 58 in the direction of the first connection passage 16 may be closed, so that the refrigerant may not flow into the first connection passage 16. [

Thus, the refrigerant compressed in the compression section 14 can flow to the condenser 52 along the condenser inlet flow path 54. The refrigerant condensed in the condenser 52 may flow to the main valve device 56 through the condenser outlet flow path 55.

The main valve device 56 may allow a part of the introduced refrigerant to flow into the first refrigerant passage 214 and the remaining part thereof to flow into the second refrigerant passage 224. [ At this time, the amount of the refrigerant flowing into each of the refrigerant flow paths 214 and 224 may vary depending on the cooling load required in the freezing room 21 and the freezing room 22, respectively.

The refrigerant flowing into the first refrigerant passage 214 may be expanded in the first expansion mechanism 213 and flow to the first evaporator 211 disposed in the rear of the freezer compartment 21. The refrigerant can be evaporated by heat exchange with the air in the first evaporator 211. The first evaporation fan 212 can heat the air exchanged with the refrigerant in the vicinity of the first evaporator 211 through the first air discharge opening 61, (21). Thereby, the temperature of the freezing chamber 21 can be kept low.

The refrigerant flowing into the second refrigerant passage 224 may be expanded in the second expansion mechanism 223 and flow into the second evaporator 221 disposed in the rear of the refrigerating chamber 22. [ The second evaporator 221 is connected to the second evaporator 221 through the second cool air discharge port 62. The refrigerant can be evaporated by heat exchange with the air in the second evaporator 221, (22). ≪ / RTI > Thereby, the temperature of the refrigerating compartment 22 can be kept low.

The refrigerant vaporized in each of the evaporators 211 and 221 can be sucked into the compressor 51 of the compression unit 14 through the suction flow path 19. The compressor (51) compresses the sucked refrigerant again and discharges it to the discharge passage (15), thereby circulating the refrigerant along the refrigeration and / or refrigeration cycle.

In the single operation of the refrigeration and / or refrigeration system, all of the refrigerant is circulated along the refrigeration and / or refrigeration cycle, so that refrigeration and / or refrigeration performance can be improved compared to the case of simultaneous operation with the air conditioning system.

5 is a diagram showing the flow of the refrigerant during the single operation of the air conditioning system.

5, when the refrigeration and / or refrigeration system is stopped and the air conditioning system is operated alone, all the refrigerant introduced into the sub valve device 58 through the discharge passage 15 flows into the first connection passage 16 Can be adjusted to flow. In this case, the passage in the direction of the condenser inlet flow path 54 of the sub valve device 58 is closed and the refrigerant does not flow into the condenser inlet flow path 54.

Since the flow of the refrigerant according to the operation of the air conditioning system has been described above, the redundant description is omitted.

6 is a perspective view showing the air conditioning unit.

Referring to FIG. 6, the air conditioning unit 40 may include a suction port 45 and a discharge port 44. An air conditioning heat exchanger (46) and a blower opening (47) may be disposed in the air conditioning part (40). In addition, a heat storage heat exchanger (57) and an air conditioning expansion mechanism (59) can be disposed inside the air conditioning part (40).

The air conditioning part (40) may include a receiving part (41) and a duct part (42). The air conditioning part (40) may further include an intermediate part (43).

The air conditioning heat exchanger (46) and the blower opening (47) may be provided in the receiving portion (41). The heat storage heat exchanger 57 and the air conditioning expansion mechanism 59 may be located in the housing portion 41. [

The heat storage heat exchanging part (57) can be installed on the rear side of the accommodating part (41). The heat pipe 572 connected to the heat storage heat exchanging part 57 can pass through the rear surface of the receiving part 41. Or the heat pipe 572 may pass through a hole (not shown) formed in the rear surface of the receiving portion 41, and a part of the heat pipe 572 may be located outside the main body 10.

The heat of condensation of the refrigerant is stored in the heat storage material 571 of the heat storage heat exchanger 57 so that the air in the vicinity of the heat storage heat exchanger 57 can be heated. Therefore, when the air conditioning heat exchanger 46 and the heat storage heat exchanging part 57 are too close to each other, the air exchanged with the refrigerant in the air conditioning heat exchanger 46 may not be sufficiently cooled. Therefore, the heat storage heat exchanging part 57 can be disposed apart from the air conditioning heat exchanger 46 by a predetermined distance.

An air conditioning part barrier 400 may be provided between the heat storage heat exchanging part 57 and the air conditioning heat exchanger 46. The air conditioning part barrier 400 may be an insulating wall.

The air conditioning heat exchanger 57 may be located behind the air conditioning part barrier 400 and the air conditioning heat exchanger 46 may be located in front of the air conditioning part barrier 400. [

The cross sectional area of the air conditioning part barrier 400 may coincide with the cross sectional area of the accommodating part 41. [

The accommodation portion 41 can be adiabatically divided into a region where the heat storage heat exchanging portion 57 is installed and a region where the air conditioning heat exchanger 46 is installed by the air conditioning portion barrier 400. [ Therefore, it is possible to prevent the heat radiated from the heat storage heat exchanger (57) by the air conditioning part barrier (400) from heating the air around the air conditioning heat exchanger (46).

The suction port 45 may be formed in the receiving portion 41. More specifically, a suction port 45 may be formed on the side surface of the housing portion 41. [ The suction port 45 may be formed on the left side and / or the right side of the accommodating portion 41.

The intake port 45 may be formed between the heat storage heat exchanger 57 and the air conditioning heat exchanger 46. More specifically, the inlet port 45 may be formed between the air conditioning part barrier 400 and the air conditioning heat exchanger 46. That is, the inlet port 45 may be located forward of the air conditioning unit barrier 400 and may be located behind the air conditioning heat exchanger 46.

The air conditioning heat exchanger (46) may be disposed between the suction port (45) and the discharge port (44) along the flow direction of the air.

The air sucked into the suction port 45 by the blowing mechanism 47 is not heated by the heat storage heat exchanger 57 but can be cooled by the air conditioning heat exchanger 46 and discharged to the discharge port 44. [

The air conditioning expansion mechanism (59) can be disposed behind the air conditioning part barrier (400). Preferably, the air conditioning expansion mechanism (59) is disposed in front of the air conditioning part barrier (400).

At least one of the second connection passage 17 and the air-conditioning passage 18 connecting the heat storage heat exchanger 57 and the air conditioning heat exchanger 46 can pass through the air conditioning part barrier 17. Alternatively, the second connection passage 17 and / or the air-conditioning passage 18 can be bypassed without passing through the air-conditioning section barrier 400. [

The blower port (47) may be disposed between the air conditioning heat exchanger (46) and the discharge port (44). Alternatively, the blower port 47 may be disposed between the air inlet port 45 and the air conditioning heat exchanger 46.

The blower orifice 47 may be disposed in front of the air conditioning part barrier 400.

The air sucked from the suction port 45 by the blower port 47 is cooled by passing through the air conditioning heat exchanger 46 and the cooled air can be discharged to the discharge port 44 by the blower port 47.

The duct portion 42 may communicate with the receiving portion 41 and the discharge port 44 may be formed. The discharge port 44 may be provided with a direction adjusting member 440 that can adjust the direction of the discharged air.

The duct portion 42 may be located in front of the receiving portion 41, but is not limited thereto.

The discharge port 44 may be formed on the front surface of the air conditioning part 40. More specifically, the discharge port 44 may be formed on the front surface of the duct portion 42.

The accommodating portion 41 must be provided with the duct portion (not shown) so that the air conditioning heat exchanger 46, the heat accumulating heat exchanging portion 57, the air conditioning expansion mechanism 59 and the blower opening 47 are provided in the accommodating portion 41, 42). That is, the cross-sectional area of the duct portion 42 may be narrower than the cross-sectional area of the accommodating portion 41.

Therefore, the cool air flowing in the accommodating portion 41 can pass through the duct portion 42 and can flow at a higher flow speed, can be discharged from the discharge port 44, and can be spread farther. Thereby, there is an advantage that the air conditioning function of the refrigerator 1 can be further improved.

The intermediate portion 43 may be located between the accommodating portion 41 and the duct portion 42. The intermediate portion 43 communicates with the accommodating portion 41 and can communicate with the duct portion 42.

The sectional area of the intermediate portion 43 may become narrower toward the duct portion 42 side from the receiving portion 41 side. That is, at least a part of the outer surface of the intermediate portion 43 may include a sphere rear surface.

As described above, the cross-sectional area of the duct portion 42 may be narrower than the cross-sectional area of the accommodating portion 41. If the intermediate portion 43 does not exist at this time, the area between the accommodating portion 41 and the duct portion 42 changes abruptly, so that a part of the air blown by the blower opening 47 flows into the duct portion 42, It can be reflected by the inner wall of the receiving portion 41 and returned to the receiving portion 41. [

The intermediate portion 43 may serve to gradually reduce the cross sectional area difference between the accommodating portion 41 and the duct portion 42. Thereby, the air flowed by the blower orifice 47 can flow along the spherical surface of the intermediate portion 43, and the entire air can flow into the duct portion 42.

The upper outer surface of the air conditioning part 40 may be the upper surface of the main body 10. The upper outer surface of the accommodating portion 41, the duct portion 42, and the intermediate portion 43 may be a single flat surface without a step. The duct portion 42 and the intermediate portion 43 may be located above the storage portion 20.

The length of the accommodating portion 41, the duct portion 42, and the intermediate portion 43 may be the same. The vertical length of the duct portion 42 and the intermediate portion 43 is equal to the length of the receiving portion 41 because the sectional area of the duct portion 42 and that of the intermediate portion 43 are smaller than the sectional area of the receiving portion 41. [ May be shorter than the length in the up and down direction. Thereby, the storage section 20 can be widened.

According to the present embodiment, it is possible to cool the predetermined space only by the refrigerator.

Also, the heat storage material 571 serving as a condenser is included in the heat storage heat exchanger 57, so that the amount of heat required for cooling can be dissipated without a separate outdoor unit.

Further, a heat pipe 572 is connected to the heat storage material 571, so that cooling and heat radiation can be simultaneously performed.

In addition, heat dissipation is possible without additional power, so that power consumption can be minimized.

Further, the machine room 50 can be made compact by configuring the air conditioning system with the refrigeration and / or refrigeration system using a single compressor 51. [

7 is an overall configuration diagram illustrating an internal configuration of a refrigerator according to another embodiment of the present invention.

Hereinafter, the same descriptions as those described above will be omitted and differences will be mainly described.

Referring to FIG. 7, the refrigerator 1 'according to the present embodiment may be configured independently of the refrigeration and / or refrigeration system and the air conditioning system. In more detail, the refrigerant circulating in the refrigeration and / or refrigeration system and the refrigerant circulating in the air conditioning system can circulate independently without being split or merged with each other.

The refrigerator 1 'according to the present embodiment may include an air conditioning compressor 511 and a main compressor 512. More specifically, the air conditioning compressor 511 constitutes an air conditioning system, and the main compressor 512 constitutes a refrigeration and / or refrigeration system.

The air conditioning compressor 511 may correspond to the compression unit 14 of the refrigerator 1 according to the embodiment described above.

All the constituent elements of the air conditioning system can be disposed in the air conditioning part 40.

The air conditioning compressor 511 and the main compressor 512 may be disposed apart from each other. More specifically, the air conditioning compressor 511 may be installed in the air conditioning unit 40 and the main compressor 512 may be installed in the machine room 50.

At this time, the air conditioning compressor 511 may be disposed before the air conditioning heat exchanger 46 along the air flow direction. This is because heat is generated when the air conditioning compressor 511 is driven, and air passing around the air conditioning air conditioning compressor 511 can be heated.

That is, the air conditioning heat exchanger 46 may be disposed between the air conditioning compressor 511 and the discharge port 44. Thereby, the air cooled by the air conditioning heat exchanger (46) can be discharged to the discharge port (44) without being heated subsequently.

The air conditioning compressor (511) may be disposed in front of the air conditioning part barrier (400). On the other hand, it is also possible that the air conditioning compressor 511 is arranged behind the air conditioning part barrier 400.

The suction port 45 may be formed in front of the air conditioning part barrier 400. When the air conditioning compressor 511 is installed in front of the air conditioning part barrier 400, the air inlet 45 can be formed between the air conditioning compressor 511 and the air conditioning heat exchanger 46.

The air conditioning compressor 511 may be connected to the suction passage 19 and the first connection passage 16, respectively. The air conditioning compressor (511) can compress the refrigerant sucked through the suction passage (19) into a gaseous refrigerant of high temperature and high pressure. The refrigerant compressed in the air conditioning compressor (511) can be discharged to the first connection passage (16).

The first connection passage 16 can connect the air conditioning compressor 511 and the heat storage heat exchanger 57. More specifically, the first connection passage 16 can connect the air conditioning compressor 511 and the heat exchanger 570.

The refrigerant flowing into the heat exchanger 570 through the first connection passage 16 can be condensed by heat exchange with the heat storage material 571.

The refrigerant condensed in the heat exchanger 570 can flow out through the second connection passage 17 and expand through the air conditioning expansion mechanism 59. The expanded refrigerant can flow into the air conditioning heat exchanger 46 through the air conditioning duct 18 and can be evaporated by heat exchange with the air in the air conditioning heat exchanger 46.

The suction flow path 19 can connect the air conditioning compressor 511 with the air conditioning heat exchanger 46. The refrigerant evaporated in the air conditioning heat exchanger (46) can be sucked into the air conditioning compressor (511) through the suction passage (19). Thereby, the air conditioning system can be constructed.

Hereinafter, the refrigeration and / or refrigeration system will be described.

The main compressor 512 may be connected to the sub suction path 23 and the condenser inflow path 54, respectively. The main compressor 512 can compress the refrigerant sucked in through the sub-suction flow path 23 into a gaseous refrigerant of high temperature and high pressure. The refrigerant compressed in the main compressor 512 may be discharged to the condenser inlet flow path 54.

The condenser inlet flow path 54 can connect the main compressor 512 and the condenser 52. The refrigerant flowing into the condenser 52 through the condenser inlet flow path 54 can be heat-exchanged with the air and condensed.

The condenser outlet flow path 55 can connect the main valve device 56 and the condenser 52. The refrigerant condensed in the condenser 52 may flow into the main valve device 56 through the condenser outlet flow path 55.

At least one refrigerant passage (214, 224) may be connected to the main valve device (56). For example, the first refrigerant passage 214 and the second refrigerant passage 224 may be connected to the main valve device 56, respectively.

At least one of the refrigerant channels 214 and 224 may connect the main valve unit 56 and the at least one evaporator 211 and 221. For example, the first refrigerant passage 214 may be connected to the first evaporator 211 for cooling the interior of the freezer compartment 21, and the second refrigerant passage 224 may be connected to the first evaporator 211 for cooling the interior of the refrigerating compartment 22 2 evaporator 221 as shown in FIG. Since the operations of the first evaporator 211 and the second evaporator 221 are the same as those described above, a description thereof will be omitted.

At least one evaporator (211, 221) may be connected to the sub suction line (23), respectively. The refrigerant evaporated in the evaporators 211 and 221 may be sucked into the main compressor 512 through the sub suction path 23. Thereby, a refrigeration and / or refrigeration system can be constructed.

The air conditioning compressor 511 and the main compressor 512 included in the refrigerator 1 'according to the present embodiment constitute separate cooling cycles, which is advantageous in that the control of each cooling cycle becomes more convenient. Further, the cooling ability by the air conditioning system can be further improved.

The foregoing description is merely illustrative of the technical idea of the present invention, and various changes and modifications may be made by those skilled in the art without departing from the essential characteristics of the present invention.
