Description

  The present disclosure relates to an adsorber that evaporates a refrigerant by using an action of an adsorbent adsorbing a medium to be adsorbed and exhibits a refrigerating capacity by the latent heat of evaporation.

  Conventionally, as this kind of adsorber, there is an adsorber described in Patent Document 1. The adsorber described in Patent Document 1 includes a sealed container in which an adsorbent that adsorbs a refrigerant is accommodated. The hermetic container partitions a condensation / evaporation surface layer containing a refrigerant and an adsorption / desorption surface layer containing an adsorbent. The condensation / evaporation surface layer and the adsorption / desorption surface layer are communicated with each other via a communication portion. A first circulation channel and a second circulation channel through which each heat exchange medium flows are respectively arranged above and below the condensation / evaporation surface layer and the adsorption / desorption surface layer.

  In the adsorber described in Patent Document 1, the liquid phase refrigerant in the condensation / evaporation surface layer is obtained by heat exchange between the heat exchange medium flowing in the second circulation channel and the liquid phase refrigerant in the condensation / evaporation surface layer during the adsorption process. Evaporates. The heat exchange medium flowing in the second circulation channel is cooled by the latent heat of vaporization during the evaporation of the liquid phase refrigerant. At this time, the adsorption / desorption surface layer promotes evaporation by adsorbing the vapor-phase refrigerant evaporated. At this time, since the adsorbent generates heat when adsorbing the gas-phase refrigerant, the temperature of the adsorbent rises. When the temperature of the adsorbent increases, the adsorbing capacity of the adsorbent decreases. In order to suppress this, the temperature increase of the adsorbent is suppressed by performing heat exchange between the heat exchange medium flowing through the first circulation channel and the adsorbent.

JP 2007-218504 A

  By the way, in the adsorber described in Patent Document 1, during the adsorption process, the temperature of the heat exchange medium flowing through the first circulation water channel increases toward the downstream side of the first circulation water channel. Therefore, the adsorption capacity of the adsorbent in the adsorption / desorption surface layer decreases toward the downstream side of the first circulation channel. On the other hand, the temperature of the heat exchange medium flowing through the second circulation channel decreases as it goes downstream of the second circulation channel. Therefore, the liquid phase refrigerant in the condensation / evaporation surface layer is less likely to evaporate toward the downstream side of the second circulation water channel.

Thus, in the adsorber described in Patent Document 1, the adsorption capacity tends to decrease on the downstream side of each of the first circulation channel and the second circulation channel in the adsorption / desorption surface layer and the condensation / evaporation surface layer. is there. This is a factor that reduces the refrigeration capacity of the adsorber.
This indication is made in view of such a situation, and the object is to provide the adsorption machine which can improve adsorption capacity.

  An adsorber (50, 60) that solves the above problems includes a sealed container (53, 63) that accommodates the medium to be adsorbed therein, and an adsorbent (54, 60) that is disposed inside the sealed container and adsorbs the medium to be adsorbed. 64) and an adsorption core part (51, 61) for desorbing the adsorbed medium from the adsorbent by heat exchange with the first heat medium, and an inside of the sealed container, An evaporation / condensation core section (52, 62) for condensing or evaporating the adsorbed medium desorbed from the adsorbent by heat exchange. In the sealed container, the first heat medium flowing through the adsorption core portion and the second heat medium flowing through the evaporation / condensation core portion flow so as to face each other.

  According to this configuration, the downstream portion that is difficult to evaporate in the evaporation / condensation core portion can be opposed to the upstream portion that is easily adsorbed in the adsorption core portion. Further, an upstream portion that is easily evaporated in the evaporation / condensation core portion and a downstream portion that is difficult to be adsorbed in the adsorption core portion can be made to face each other. Thereby, since adsorption | suction and evaporation of the to-be-adsorbed medium in an adsorber can be balanced, the adsorptivity of an to-be-adsorbed medium can be improved.

  In addition, the code | symbol in the bracket | parenthesis as described in the said means and a claim is an example which shows a corresponding relationship with the specific means as described in embodiment mentioned later.

It is different from the connection mode. Specifically, the tank part 610 of the adsorption core part 61 is connected to the four-way valve 72.

Further, the tank part 620 of the evaporation / condensation core part 62 is connected to the four-way valve 73. The tank portion 621 of the evaporation / condensation core portion 62 is connected to the four-way valve 74.

Next, an operation example of the refrigerator 10 of the present embodiment will be described.
When the four-way valves 71 to 74 are in the connected state shown in FIG. 1, the first heat medium circulates between the adsorption core portion 51 of the first adsorber 50 and the heat source 20. Therefore, a high-temperature first heat medium whose temperature has risen in the heat source 20 flows through the adsorption core unit 51. When the first heat medium flows through the adsorption core 51, the adsorbent 54 is heated by heat exchange between the first heat medium and the adsorbent 54. As a result, the adsorbed medium is detached from the adsorbent 54.

  When the four-way valves 71 to 74 are in the connected state shown in FIG. 1, the second heat medium circulates between the evaporation / condensation core unit 52 and the second heat radiating unit 42 of the first adsorber 50. Therefore, the second heat medium cooled by exchanging heat with air in the second heat radiating portion 42 flows through the evaporation / condensation core portion 52. When the second heat medium flows through the evaporation / condensation core unit 52, the second heat medium absorbs the heat of the adsorbed medium desorbed from the adsorbent 54, thereby causing the surface of the evaporation / condensation core unit 52 to absorb the adsorbed medium. Is condensed. The adsorbed medium condensed on the surface of the evaporation / condensation core 52 is carried on the carrying member 55. As described above, the evaporation / condensation core portion 52 functions as a portion that promotes the detachment of the cooled medium from the adsorbent 54.

  On the other hand, when the four-way valves 71 to 74 are in the connected state shown in FIG. 1, the second heat medium circulates between the evaporation / condensation core unit 62 of the second adsorber 60 and the cold heat generator 30. When the second heat medium flows through the evaporation / condensation core portion 62, heat exchange is performed between the adsorbed medium supported by the support member 65 and the second heat medium, so that the target supported by the support member 65 is supported. The adsorption medium evaporates. The second heat medium is cooled by the latent heat of evaporation generated at this time. The cooled second heat medium flows through the cold heat generator 30 to generate cold heat from the cold heat generator 30. The adsorbed medium evaporated from the holding member 65 is adsorbed by the adsorbent 64 of the adsorption core unit 61.

  In addition, when the four-way valves 71 to 74 are in the connected state shown in FIG. 1, the first heat medium circulates between the adsorption core portion 61 and the first heat radiation portion 41 of the second adsorber 60. Accordingly, the first heat medium cooled by exchanging heat with air in the first heat radiating portion 41 flows through the adsorption core portion 61. When the first heat medium flows through the adsorption core portion 61, the adsorbent 64 is cooled by the first heat medium absorbing the heat of the adsorbent 64. Thereby, the adsorptivity of the adsorbed medium by the adsorbent 64 is enhanced.

  Thus, when the four-way valves 71 to 74 are in the connected state shown in FIG. 1, the first adsorber 50 desorbs the adsorbed medium from the adsorbent 54 by heat exchange with the first heat medium, The desorbed adsorbed medium condenses. In the second adsorber 60, the adsorbed medium evaporates from the holding member 65 and the evaporated adsorbed medium is adsorbed by the adsorbent 64.

  The refrigerator 10 maintains the connection state of the four-way valves 71 to 74 for a predetermined time in the state shown in FIG. 1, and then switches the connection state of the four-way valves 71 to 74 to the state shown in FIG. Accordingly, the second heat medium circulates between the evaporation / condensation core portion 52 of the first adsorber 50 and the cold heat generator 30. When the second heat medium flows through the evaporation / condensation core portion 52, heat exchange is performed between the adsorbed medium supported by the support member 55 and the second heat medium, so that the target supported by the support member 55 is supported. The adsorption medium evaporates. The second heat medium is cooled by the latent heat of evaporation generated at this time. The cooled second heat medium flows through the cold heat generator 30 to generate cold heat from the cold heat generator 30. The adsorbed medium evaporated from the support member 55 is adsorbed by the adsorbent 54 of the adsorption core unit 51.

  In addition, when the four-way valves 71 to 74 are in the connected state shown in FIG. 2, the first heat medium circulates between the adsorption core portion 51 and the first heat radiating portion 41 of the first adsorber 50. Therefore, the first heat medium cooled by exchanging heat with air in the first heat radiating portion 41 flows through the adsorption core portion 51. When the first heat medium flows through the adsorption core 51, the adsorbent 54 is cooled by the heat of the adsorbent 54 being absorbed by the first heat medium. Thereby, the adsorptivity of the adsorbed medium by the adsorbent 54 is enhanced.

  On the other hand, when the four-way valves 71 to 74 are in the connected state shown in FIG. 2, the first heat medium circulates between the adsorption core portion 61 of the second adsorber 60 and the heat source 20. Therefore, a high-temperature first heat medium whose temperature has increased in the heat source 20 flows through the adsorption core unit 61. When the first heat medium flows through the adsorption core portion 61, the heat of the first heat medium is transmitted to the adsorbent 64, whereby the adsorbent 64 is heated. As a result, the adsorbed medium is detached from the adsorbent 64.

  Further, when the four-way valves 71 to 74 are in the connected state shown in FIG. 2, the second heat medium circulates between the evaporation / condensation core portion 62 and the second heat radiating portion 42 of the second adsorber 60. Therefore, the second heat medium cooled by exchanging heat with air in the second heat radiating portion 42 flows through the evaporation / condensation core portion 62. When the second heat medium flows through the evaporation / condensation core unit 62, the second heat medium absorbs the heat of the adsorbed medium desorbed from the adsorbent 64, thereby causing the adsorbed medium on the surface of the evaporation / condensation core unit 62. Is condensed. The adsorbed medium condensed on the surface of the evaporation / condensation core unit 62 is carried on the carrying member 65. As described above, the evaporation / condensation core unit 62 functions as a portion that promotes the detachment of the cooling medium from the adsorbent 64.

  Thus, when the four-way valves 71 to 74 are in the connected state shown in FIG. 2, the second adsorber 60 desorbs the adsorbed medium from the adsorbent 64 by heat exchange with the first heat medium, and The desorbed adsorbed medium condenses. In the first adsorber 50, the adsorbed medium evaporates from the holding member 55 and the evaporated adsorbed medium is adsorbed by the adsorbent 54.

  The refrigerator 10 maintains the connection state of the four-way valves 71 to 74 for a predetermined time in the state shown in FIG. 2, and then switches the connection state of the four-way valves 71 to 74 to the state shown in FIG. Thereafter, the refrigerator 10 continuously generates cold from the cold generator 30 by switching the connection state of the four-way valves 71 to 74 between the state shown in FIG. 1 and the state shown in FIG. Let

  Incidentally, as shown in FIG. 2, when the adsorbed medium evaporates in the first adsorber 50, the first adsorber 50 includes the first heat medium flowing through the adsorbing core portion 51 and the evaporation / condensation core portion 52. The flowing second heat medium flows oppositely. Accordingly, in the evaporation / condensation core portion 52, the tubular member 523b disposed on the downstream side in the flow direction of the second heat medium rather than the tubular member 523a disposed on the upstream side in the flow direction of the second heat medium. Decreases in temperature. Therefore, the adsorbed medium is less likely to evaporate in the holding member 55 of the tubular member 523b than in the holding member 55 of the tubular member 523a. Further, in the adsorption core portion 51, the temperature of the tubular member 523a disposed on the downstream side in the flow direction of the first heat medium is higher than that of the tubular member 513b disposed on the upstream side in the flow direction of the first heat medium. To rise. Therefore, the adsorbent 54 of the tubular member 513b is easier to adsorb the adsorbed medium than the adsorbent 54 of the tubular member 513a.

  That is, in the first adsorber 50, the downstream portion that is difficult to evaporate in the evaporation / condensation core portion 52 and the upstream portion that is easily adsorbed in the adsorption core portion 51 face each other. Further, the upstream portion that is likely to evaporate in the evaporation / condensation core portion 52 and the downstream portion that is difficult to be adsorbed in the adsorption core portion 51 face each other. Thereby, since adsorption and evaporation of the adsorbed medium in the first adsorber 50 can be balanced, the adsorbability of the adsorbed medium can be improved.

  As shown in FIG. 3, in the first adsorber 50, the inner region of the sealed container 53 is partitioned into a first inner region A <b> 11 and a second inner region A <b> 12 by the partition plate 56. Thereby, since the inflow / outflow of the adsorbed medium between the first internal region A11 and the second internal region A12 can be suppressed, the adsorbability of the adsorbed medium can be further improved.

  Similarly, as shown in FIG. 1, when the adsorbed medium evaporates in the second adsorber 60, the second adsorber 60 includes the first heat medium flowing through the adsorbing core part 51 and the evaporation / condensation core part 52. And the second heat medium flowing through the counter flow. Therefore, the second adsorber 60 can obtain the same operations and effects as the first adsorber 50.

According to the 1st adsorption device 50 and the 2nd adsorption device 60 of this embodiment explained above, the operation and effect shown by the following (1)-(4) can be acquired.
(1) In the first adsorber 50, in the sealed container 53, the first heat medium flowing through the adsorption core unit 51 and the second heat medium flowing through the evaporation / condensation core unit 52 flow so as to face each other. Also in the second adsorber 60, in the sealed container 63, the first heat medium flowing through the adsorption core portion 61 and the second heat medium flowing through the evaporation / condensation core portion 62 flow so as to face each other. Thereby, since the adsorption and evaporation of the adsorbed medium in the first adsorber 50 and the second adsorber 60 can be balanced, the adsorbability of the adsorbed medium can be improved.

  (2) The first adsorber 50 includes a partition plate 56 that partitions the inside of the sealed container 53 into a first internal region A11 and a second internal region A12. Thereby, since the inflow / outflow of the adsorbed medium between the first internal region A11 and the second internal region A12 can be suppressed, the adsorbability of the adsorbed medium can be further improved. Moreover, since the 2nd adsorption device 60 is also provided with the partition plate 66 which has the same function, the same effect | action and effect can be acquired.

(3) The partition plate 56 of the first adsorber 50 and the partition plate 66 of the second adsorber 60 are made of a heat insulating material. Thereby, since heat transfer between the first internal region A11 and the second internal region A12 can be suppressed, the adsorptivity of the adsorbed medium can be further improved.
(4) The tubular members 513a and 513b of the adsorption core portion 51 of the first adsorber 50 are orthogonal to the tank portions 510, 511, 520, and 521. Further, the tubular members 613 a and 613 b of the adsorption core portion 61 of the second adsorber 60 are orthogonal to the tank portions 610, 611, 620 and 621. Thereby, since each heat transfer area of the 1st adsorption device 50 and the 2nd adsorption device 60 can be expanded, the adsorption performance of the 1st adsorption device 50 and the 2nd adsorption device 60 can be improved.

In addition, the said embodiment can also be implemented with the following forms.
As shown in FIG. 4, the partition plate 56 of the first adsorber 50 may be formed with a slit 560 extending in a direction orthogonal to both the vertical direction and the horizontal direction. The slit 560 is disposed between the adsorption core unit 51 and the evaporation / condensation core unit 52 in FIG. According to such a configuration, the heat leak between the adsorption core unit 51 and the evaporation / condensation core unit 52 via the partition plate 56 is suppressed, so that the adsorption performance of the first adsorber 50 can be further improved. Can do. Moreover, if the same slit is formed also in the partition plate 66 of the 2nd adsorption device 60, the same effect | action and effect can be acquired.

  As shown in FIG. 5, the first adsorber 50 may have a structure that does not have the support member 55. In this case, when the adsorbed medium is condensed by heat exchange with the evaporation / condensation core unit 52, if the condensed adsorbed medium is stored in the bottom wall portion 533 of the sealed container 53, the evaporation / condensation core unit 52 is You will be immersed in. A similar configuration can also be applied to the second adsorber 60.

As shown in FIG. 6, the sealed container 53 of the first adsorber 50 may be partitioned into a plurality of internal regions by a plurality of partition plates 56. A similar configuration can also be applied to the second adsorber 60.
-As FIG. 7 shows, the 1st adsorption device 50 may be comprised by several adsorption | suction part 50a, 50b. Each adsorption | suction part 50a, 50b has the structure remove | excluding the partition plate 56 from the structure of the 1st adsorption | suction device 50 shown by FIG. Each adsorption core part 51 of adsorption part 50a, 50b is mutually connected via channel 75a. Further, the respective evaporation / condensation core portions 52 of the adsorbing portions 50a and 50b are connected to each other via a flow path 75b. Even in such a configuration, since the inner region of the sealed container 53 of the suction portion 50a and the inner region of the sealed container 53 of the suction portion 50b are substantially separated, the first suction having the partition plate 56 is performed. Functions and effects similar to those of the vessel 50 can be obtained. Similarly, the 2nd adsorption device 60 may be constituted by a plurality of adsorption parts 60a and 60b.

  -The adsorption | suction core part 51 and the evaporation / condensation core part 52 of the 1st adsorption device 50 may consist of a drone cup type heat exchange part. For example, the adsorption core part 51 may have a structure as shown in FIG. As shown in FIG. 8, the suction core portion 51 is configured by stacking a plurality of drone cup plates 57. In this case, the partition plate 56 can be easily provided in the suction core portion 51 only by sandwiching the partition plate 56 between the adjacent drone cup plates 57 and 57. In addition, the wave-shaped member provided in the tubular members 513a and 513b is an inner fin. Further, even when the evaporation / condensation core part 52 is composed of a drone cup type heat exchange part, the partition plate 56 can be easily provided on the evaporation / condensation core part 52. Therefore, the 1st adsorption device 50 of the said embodiment can be manufactured easily. Similarly, if the adsorption core unit 61 and the evaporation / condensation core unit 62 of the second adsorber 60 are configured by a drone cup type heat exchange unit, the second adsorber 60 of the above embodiment can be easily manufactured. .
