Description

  The present invention relates to an adsorber that evaporates a refrigerant by utilizing the action of an adsorbent adsorbing a gas-phase refrigerant and exhibits a refrigerating capacity by the latent heat of evaporation, and is particularly effective when applied to an air conditioner. is there.

  Conventionally, as an adsorber of this type, for example, as shown in Patent Document 1, only an adsorbent / desorbent layer, which is an adsorbent chamber composed of a fin member and an adsorbent filled between the fin members, and the fin member are used. There is known an adsorber in which condensing and evaporating surface layers, which are refrigerant chambers, are stacked opposite to each other with a fiber mat-like heat insulating layer interposed therebetween.

JP 2002-107003 A

  However, in Patent Document 1 described above, heat exchange media having different temperatures are circulated in the circulating water passages stacked outside the sealed container, thereby reducing heat loss due to heat transfer generated between the circulating water passages. For the sake of illustration, the suction / desorption agent layer and the condensation / evaporation surface layer are disposed opposite to each other via a heat insulating layer, and the upper and lower outer plates of the sealed container form a sealed container via a resin material. It is configured. Accordingly, there is a problem that the number of parts constituting the sealed container is large.

  In addition to the purpose of heat insulation, this heat insulation layer has a communication function for absorbing vapor and flowing into and out of the desorbent layer, a strength function for maintaining vacuum strength, and an inorganic material so as not to generate gas inside. It is necessary to form with. In Patent Document 1, for example, a heat-insulating layer is formed using a plastic crimped fiber mat, a PET honeycomb, or the like, but includes a honeycomb structure that forms an absorption / desorption agent layer and a condensation / evaporation surface layer. There is a problem of using relatively expensive parts.

  In view of this, the inventors have simplified the sealed container in which the absorption / desorption agent layer and the condensation / evaporation surface layer are arranged to reduce the manufacturing cost and reduce the floor area of the sealed container. A circulating water channel made of a resin material through which each heat exchange medium flows is formed on the upper and lower surfaces of the sealed container in which the absorbing / desorbing agent layer and the condensing / evaporating surface layer are accommodated.

  More specifically, as shown in Japanese Patent Application No. 2005-16065 (another embodiment) and FIG. 13, the first and second circulating water flow paths 260 and 270 that are jackets are thermally conducted outside the sealed container. The adsorber 200 is formed of a resin material having a low rate, and two or more adsorbers 200 are stacked in N stages.

  As a result, when the adsorber 200 is composed of a closed container and the first and second circulating water flow paths 260 and 270 with different materials, the adsorber 200 can be downsized. It has been found that the number of assembly steps to be integrated as the adsorber 200 increases.

  By the way, in patent document 1 and the above-mentioned Japanese Patent Application No. 2005-16065, the first and second circulating water flow paths 260 and 270 are formed in respective layers by disposing the suction and desorption agent layers and the condensation and evaporation surface layers opposite to each other. Therefore, there is a problem that the floor area of the sealed container increases when the heat exchange performance is improved.

  In view of the above, an object of the present invention is to provide an adsorber that can reduce heat loss generated between circulating water flow paths and can be reduced in size and manufacturing cost.

  First, in the adsorber 200 configured in a single stage, a sealed container 210 that stores therein a refrigerant and an adsorbent 223 that adsorbs the vapor of the refrigerant, and respective heat exchange media are distributed above and below the sealed container 210. An adsorber module having first and second circulating water flow paths 260 and 270, which are jackets, is formed.

  Here, the sealed container 210 has a condensing / evaporating surface layer 230 that is a refrigerant chamber in which a refrigerant is disposed, an adsorption / desorption layer 220 that is an adsorbent chamber in which the adsorbent 223 is disposed, and a communication between them. The portion 240 is formed as an integral structure.

A first circulating water channel 260 protruding in a convex shape through which the heat exchange medium flows outside the 220 side and a second circulation protruding in a convex shape through which the heat exchange medium flows outside the condensation and evaporation surface layer 230 side of the other side. The outer edges of the first and second circulating water flow paths 260 and 270 are formed so as to be joined to the hermetic container 210 so that the water flow path 270 is hermetically sealed.

  Further, as shown in FIG. 1A, each of the first and second circulating water flow paths 260, 270 is formed with, for example, three rows of U-turn flow paths so as to meander outside the sealed container 210. In addition, inflow / outflow pipes 262 and 272 which are inflow / outflow channels for the respective heat exchange media to flow in / out are formed at the ends of the respective channels.

  Thereby, each heat exchange medium is distributed as shown by the arrows in the figure. The heat exchange medium A circulates in the first circulating water flow path 260, and the heat exchange medium B circulates in the second circulating water flow path 270. The heat exchange medium A and the heat exchange medium B will be described later. Further, first and second external fin members 261 and 271 described later are provided in the first and second circulating water flow paths 260 and 270, respectively.

  Next, as shown in FIG. 1B and FIG. 1C, the sealed container 210 uses at least two thin plate materials (for example, a plate thickness of about 0.1 mm), and each plate material. The space protruding in the shape of the refrigerant and the adsorbent 223 and the communication portion 240 through which the vapor of the refrigerant enters and exits the adsorbent 223 are formed by press molding.

  Further, the communication part 240 formed between the adsorption / desorption layer 220 and the condensation / evaporation surface layer 230 is formed so as to restrict the space protruding in a convex shape, and the condensation / evaporation surface layer 230 side. A bottom-up weir is formed so that the refrigerant disposed in the bottom does not flow into the adsorption / desorption layer 220 side.

  The height of the weir is preferably about ½ or more of the space height on the condensation and evaporation surface layer 230 side. Note that the opening height of the communication portion 240 is preferably about ¼ to ½ of the space height on the adsorption, desorption layer 220 and condensation / evaporation surface layer 230 side.

  In the inside of the adsorption / desorption layer 220 and the condensation / evaporation surface layer 230, as shown in FIG. 2, an adsorbent 223 such as silica gel is disposed on one side and a refrigerant is disposed on the other side, and the first internal fin on one side. A second internal fin member 231 is provided on the other side of the member 221.

  Further, the first internal fin member 221 is provided with an adsorbent 223 such as silica gel with a coating having a thickness of about several hundred microns on the entire surface of the heat transfer surface having a wave shape. Therefore, as shown in the drawing, a steam passage S through which steam can flow is formed between adjacent heat transfer surfaces.

  Accordingly, the first internal fin member 221 is disposed in the longitudinal direction with respect to the communication portion 240, and the steam passage S is formed in the longitudinal direction, so that the steam flowing from the communication portion 240 is allowed to flow into the steam passage S. Therefore, it is possible to easily circulate to the back of the left end in the adsorption / desorption layer 220.

  By the way, the adsorbent 223 disposed in the adsorption / desorption layer 220 has a film thickness of about several hundred microns on the inner surface of the adsorption / desorption layer 220 in addition to the first internal fin member 221. Is provided by a coating having That is, heat generated by the adsorption / desorption action of the adsorbent 223 in the adsorption / desorption layer 220 can be transferred to the outside of the adsorption / desorption layer 220.

  On the other hand, the second internal fin member 231 is a fin having a heat transfer surface for promoting heat exchange of heat generated by the condensation and evaporation of the refrigerant. Specifically, as shown in FIG. In addition, a thin plate material (for example, a thickness of about 0.05 to 0.1 m) is used to form a corrugated shape, and both ends of the folded portion of the folded surface are condensed and the inner surface of the evaporation surface layer 230 is applied. It is formed to have a fin height that touches.

  The bent portions are arranged in the condensing and evaporating surface layer 230 so that the bent portions are arranged in the horizontal direction, and both ends of the bent portions are condensed and joined to the inner surface of the evaporating surface layer 230. The first internal fin member 221 and the second internal fin member 231 having the above shapes function as a reinforcing member of the sealed container 210 by being joined to the inner surface of the adsorption / desorption layer 220 and the condensation / evaporation surface layer 230. Have.

  By the way, the first and second external fin members 261 and 271 disposed in the first and second circulating water flow paths 260 and 270 are external to either the adsorption / desorption layer 220 or the condensation / evaporation surface layer 230. It is a fin comprising a heat transfer surface for promoting heat exchange between the heat transferred to the upper and lower surfaces and the heat exchange medium circulated in the first or second circulating water flow paths 260 and 270.

  Accordingly, the outer fin members 261 and 271 are also specifically made of thin plate materials (for example, a plate thickness of about 0.05 to 0.1 m, as shown in FIGS. 2A and 2B). ), And both ends of the bent portion of the folded surface are formed so as to have a fin height that contacts the inner surfaces of the first or second circulating water flow paths 260 and 270.

  The external fin members 261 and 271 have the outer shape and quantity divided into shapes and numbers corresponding to the flow of the flow path through which the heat exchange medium flows. In addition, the first and second external fin members 261 and 271 configured as described above also function as a reinforcing member of the heat medium casing 250 by being joined to the inner surfaces of the first and second circulating water flow paths 260 and 270. have.

It is made of a material (for example, a copper material or an alloy material containing copper, or aluminum or an alloy material containing aluminum).

  Thereby, the adsorber 200 can be formed by integral brazing in a furnace. In addition, when using an aluminum-based material, the encapsulated refrigerant, for example, generates hydrogen gas due to the reaction between water and aluminum. For this reason, a special surface treatment (for example, a glass film) is used to prevent this. )is required.

  Here, a method of assembling the adsorber 200 configured in a single stage with the above configuration will be described. First, the adsorbent 223 is disposed on the heat transfer surface of the first internal fin member 221 with a film thickness of about several hundred microns by coating. Then, in the two plate materials forming the sealed container 210, the adsorbent 223 with a film thickness of about several hundred microns is disposed on the inner surface of the plate material forming the adsorption / desorption layer 220 by coating.

Thus, the first internal fin member 221 is disposed in the adsorption / desorption layer 220, the second internal fin member 231 is condensed and disposed in the evaporation surface layer 230, and the first external fin member 261 is in the first circulation. The second external fin member 271 is disposed in the second circulating water channel 270 and is disposed in the water channel 260.

You may comprise so that it may do.

  Specifically, as shown in FIG. 4, the first and second circulating water flow paths 260 and 270 are at the top, the sealed container 210 is below, and the first and second circulating water flow paths 260 and 270 are below it. The sealed container 210 is arranged below, and the first and second circulating water channels 260 and 270 are stacked in a plurality of stages at the bottom.

  More specifically, the heat medium casing 250 having the first and second circulating water flow paths 260 and 270 is the outermost part, and an airtight container having an adsorption, desorption layer 220, condensation, and evaporation surface layer 230 thereunder. 210, and a plurality of layers of the first and second circulating water flow paths 260 and 270 are stacked in that order, and the heat medium casing 250 is stacked on the outermost part.

  The first and second circulating water channels 260 and 270 stacked on the inner side of the first and second circulating water channels 260 and 270 stacked on the outermost side are formed by stacking the sealed containers 210. It is configured.

  As shown in FIGS. 4 and 5B, the inflow / outflow pipes 262 and 272 serving as the inflow / outflow channels form an inlet / outlet end in the outermost heat medium casing 250 and the sealed containers 210 at each stage. Are formed so that the inflow / outflow pipes 262 and 272 pass through and extend to the lowermost heat medium casing 250, and are stacked in each stage in the middle of the inflow / outflow pipes 262 and 272. The first and second circulating water flow paths 260 and 270 are formed so that the heat exchange medium can be distributed or gathered.

  Here, the inflow / outflow pipes 262 and 272 formed on both ends of the sealed container 210 are formed so as to penetrate part of both ends of the sealed container 210, as shown in FIG. It is formed so as to be connected to first and second circulating water flow paths 260 and 270 stacked below the container 210.

  The first and second external fin members 261 and 271 provided in the first and second circulating water flow paths 260 and 270 have one end in the first and second circulating water flow paths 260 and 270 stacked on the outermost side. The medium casing 250 is joined to the inner surface, and the other end is joined to the outer surface of the sealed container 210.

  In addition, the first and second external fin members 261 provided in the first and second circulating water flow paths 260 and 270 stacked on the inner side of the first and second circulating water flow paths 260 and 270 stacked on the outermost part, One end and the other end of 271 are joined to the outer surface of the sealed container 210. According to the above-described adsorber 200 constituted by a plurality of stages, the floor area of the adsorber 200 can be reduced as compared with the adsorber 200 constituted by a single stage.

  Here, the operation of the adsorption refrigerator having the above-described configuration will be described. First, as shown in FIG. 3, a pump (not shown) and the blower 410 are operated to circulate the heat exchange medium and air.

  Then, the switching valves 510 and 520 are operated so that the second adsorber 200 (between the first circulating water flow path 260 on the first adsorber 200 (hereinafter referred to as the left adsorber) side and the outdoor heat exchanger 500 ( (Hereinafter referred to as the right side adsorber) between the second circulating water flow path 270 on the side and the outdoor heat exchanger 500, between the engine 100 and the first circulating water flow path 260 on the second adsorber 200 side, and the first A heat exchange medium is circulated between the second circulating water flow path 270 on the adsorber 200 side and the indoor heat exchanger 420. Hereinafter, such a state is referred to as a first state.

  At this time, since the heat exchange medium heated by the air blown into the room circulates in the second circulating water flow path 270 on the first adsorber 200 side, the liquid phase refrigerant in the condensation and evaporation surface layer 230 is evaporated. The air blown into the room is cooled by the heat exchange medium condensed by the latent heat of evaporation during the evaporation of the liquid phase refrigerant and cooled in the evaporation surface layer 230.

  At the same time, in the adsorption / desorption layer 220 on the first adsorber 200 side, the vapor-phase refrigerant evaporated by the adsorbent 223 is adsorbed to promote evaporation. At this time, the adsorbent 223 generates heat (condensation heat) when adsorbing the gas-phase refrigerant, and when the temperature of the adsorbent 223 increases, the moisture adsorption capacity decreases. A heat exchange medium is circulated between the circulating water flow path 260 and the temperature rise of the adsorbent 223 is suppressed.

  Hereinafter, the first adsorber 200 in such a state is referred to as an adsorber in an evaporation / adsorption state.

  On the other hand, since the cooling water of the engine 100 flows into the first circulating water flow path 260 on the second adsorber 200 side, the adsorbent 223 adhered in the adsorption / desorption layer 220 is heated and adsorbed. Release (desorb) moisture.

  At this time, since the heat exchange medium cooled by the outdoor heat exchanger 500 flows through the second circulating water flow path 270 on the second adsorber 200 side, the desorbed gas phase refrigerant (water vapor) Condensation is cooled by the evaporation surface layer 230 and condensed. Hereinafter, the second adsorber 200 in such a state is referred to as an adsorber in a condensed / desorbed state.

  Thus, in the first state, on the first adsorber 200 side, evaporation of the refrigerant and adsorption of the evaporated gas phase refrigerant are performed, while on the second adsorber 200 side, the adsorbed moisture Is removed, and the evaporated vapor-phase refrigerant is cooled and condensed.

  Accordingly, the condensation / evaporation surface layer 230 on the first adsorber 200 side functions as an evaporator for evaporating the liquid refrigerant, and the condensation / evaporation surface layer 230 on the second adsorber 300 side condenses the gas-phase refrigerant. Function as.

  Next, when the operation in the first state has elapsed for a predetermined time, as shown in FIG. 6, the switching valves 510 and 520 are operated, and the first circulating water flow path 260 and the outdoor heat exchanger on the second adsorber 200 side are operated. 500, between the second circulating water channel 270 on the first adsorber 200 side and the outdoor heat exchanger 500, between the engine 100 and the first circulating water channel 260 on the first adsorber 200 side, and the second. A heat exchange medium is circulated between the second circulating water flow path 270 on the adsorber 200 side and the indoor heat exchanger 420. Hereinafter, such a state is referred to as a second state.

  At this time, since the heat exchange medium heated by the air blown into the room circulates in the second circulating water channel 270 on the second adsorber 200 side, the liquid phase refrigerant in the condensation and evaporation surface layer 230 is evaporated. The air blown into the room is cooled by the heat exchange medium condensed by the latent heat of evaporation at the time of evaporation of the liquid refrigerant and cooled by the evaporation surface layer 230.

  At the same time, the adsorption / desorption layer 220 on the second adsorber 200 side suppresses an increase in the pressure in the adsorption / desorption layer 220 by adsorbing the vapor-phase refrigerant that has evaporated, and an outdoor heat exchanger. The heat exchange medium is circulated between 500 and the first heat medium casing 250 to suppress the temperature rise of the adsorbent 223.

  On the other hand, since the cooling water of the engine 100 flows into the first circulating water flow path 260 on the first adsorber 200 side, the adsorbent 223 adsorbed and adhered to the desorption layer 220 in the first state is heated, The adsorbed water is released (desorbed). At this time, since the heat exchange medium cooled by the outdoor heat exchanger 500 is circulated through the second circulating water flow path 270 on the first adsorber 200 side, the desorbed vapor phase refrigerant (water vapor) Condensation is cooled by the evaporation surface layer 230 and condensed.

  Thus, in the second state, on the second adsorber 200 side, the evaporation of the refrigerant and the adsorption of the evaporated gas phase refrigerant are performed. On the other hand, on the first adsorber 200 side, the adsorbed moisture is desorbed and the evaporated vapor phase refrigerant is cooled and condensed.

  Therefore, it functions as an evaporator that evaporates the liquid refrigerant in the condensation and evaporation surface layer 230 on the second adsorber 200 side, and condenses the gas-phase refrigerant in the condensation and evaporation surface layer 230 on the first adsorber 200 side. Functions as a condenser.

  And when predetermined time passes, it will be set as the 1st state again. In this way, the adsorption refrigerator is continuously operated while repeating the first state and the second state every predetermined time. The predetermined time is selected based on the moisture adsorption performance of the adsorbent 223 in the adsorption / desorption layer 220.

  According to the adsorber 200 according to the first embodiment described above, the sealed container 210 is a flat container in which plate materials are overlapped, and condenses that contain refrigerant, adsorption that contains the evaporation surface layer 230 and the adsorbent 223, The desorption layer 220 is partitioned, and the condensation / evaporation surface layer 230 and the adsorption / desorption layer 220 communicate with each other via the communication unit 240, and the condensation / evaporation surface layer 230 and the adsorption / desorption layer 220 First and second circulating water flow paths 260 and 270 through which the respective heat exchange media circulate are arranged on the upper and lower sides of 220.

  According to this, the heat transfer area is greatly expanded by arranging the first and second circulating water flow paths 260 and 270 through which the respective heat exchange media circulate on the upper and lower sides of the sealed container 210. Therefore, the floor area can be reduced as compared with the adsorber 200 that is oppositely bonded, thereby achieving downsizing.

  In addition, the first circulating water flow path 260 and the second circulating water flow path 270 having different heat exchange medium temperatures are arranged separately in the horizontal direction, so that heat between the first and second circulating water flow paths 260 and 270 is respectively obtained. Reduction of heat loss due to movement can be achieved. Furthermore, since the space between the first and second circulating water flow paths 260 and 270 is arranged in the lateral direction, the adsorber 200 can be formed without using any expensive heat insulating layer, so that the manufacturing cost can be reduced.

  In addition, the adsorbent 223 is held in one of the sealed containers 210 and the first internal fin member 221 having a heat transfer surface for exchanging heat with the adsorbent 223 and the other in the sealed container 210 exchange heat with the refrigerant. A second internal fin member 231 having a heat transfer surface is provided, the first and second internal fin members 221 and 231 are formed in a corrugated shape, and the bent portion is formed on the inner surface of the sealed container 210. It is joined.

  According to this, since the corrugated first and second internal fin members 221 and 231 function as reinforcing members in the sealed container 210, the outer plate of the sealed container 210 can be formed of a thin plate. Furthermore, heat loss due to heat transfer between the first and second circulating water flow paths 260 and 270 arranged separately in the lateral direction can be reduced.

  In addition, the corrugated first internal fin member 221 and the second internal fin member 231 are formed on the absorption / desorption agent layer 220 and the condensation / evaporation surface layer 230 so that the manufacturing cost is lower than that of the honeycomb structure. Can be formed with parts.

  Further, by forming the first internal fin member 221 in a corrugated shape, a gap between adjacent heat transfer surfaces can be easily set. That is, it is possible to easily set the steam channel S as the optimum channel.

  In addition, the closed container 210 is formed integrally with the condensation / evaporation surface layer 230 and the adsorption / desorption layer 220, and the communication portion 240 is disposed between them. Is formed so as to narrow the space between the condensation / evaporation surface layer 230 and the adsorption / desorption layer 220, and the bottom of the condensation / evaporation surface layer 230 is prevented from flowing into the adsorption / desorption layer 220. The weir is formed.

  According to this, since the condensation / evaporation surface layer 230, the adsorption / desorption layer 220, and the communication portion 240 are formed in an integrated structure, the sealed container 210 can be formed without increasing the number of components. Cost can be reduced. Further, since the bottom-up weir is formed, condensation and evaporation of the refrigerant of the evaporation surface layer 230 do not flow into the desorption layer 220 even when the sealed container 210 is inclined.

  Further, the communication part 240 has an opening height of about 1/4 to 1/2 of the fin height of the first and second internal fin members 221, 231. If so, it is easy for the vapor of the refrigerant to enter and exit during the adsorption and desorption operations.

  Further, the first and second circulating water flow paths 260 and 270 and the sealed container 210 are stacked in multiple stages in the vertical direction, and the inner sides of the first and second circulating water flow paths 260 and 270 stacked on the outermost part. The first and second circulating water flow paths 260 and 270 stacked on each other are configured to be formed by stacking the sealed containers 210.

  According to this, the 1st, 2nd circulating water flow path 260,270 comprised inside the outermost part can be formed with the outer plate of the airtight container 210. FIG. Thereby, the number of parts can be reduced. Moreover, the floor area of the adsorber 200 can be reduced by stacking in multiple stages.

  Moreover, even if the first and second circulating water flow paths 260 and 270 and the sealed container 210 are stacked in multiple stages, the first and second circulating water flow paths 260 and 270 through which the same heat exchange medium flows are stacked. Further, heat loss due to heat transfer between the first and second circulating water flow paths 260 and 270 can be reduced as compared with the adsorber 200 in which the conventional refrigerant and the adsorbent 223 are arranged to face each other.

  In addition, one or more inflow / outflow pipes 262 and 272 are provided in each stage of the first and second circulating water flow paths 260 and 270 to allow the heat exchange medium to flow in and out, respectively. Each stage of 270 is configured such that the heat exchange medium is distributed from the inflow / outflow pipes 262, 272 and the distributed heat exchange medium is collected in the outflow / inflow pipes 262, 272.

  According to this, since the inflow / outflow pipes 262 and 272 can have the function of a header tank, the heat exchange medium can be easily distributed and assembled in each stage of the first and second circulating water flow paths 260 and 270. . Therefore, the flow path to the inflow / outflow pipes 262 and 272 and the first and second circulating water flow paths 260 and 270 can be formed with a simple structure.

  Further, the adsorbent 223 is disposed on the inner surface of the adsorption / desorption layer 220 and the heat transfer surface of the first internal fin member 221 by coating, so that the conventional adsorbent 223 is adsorbed / desorption layer 220. Since the steam passage S is formed between the adjacent heat transfer surfaces rather than the entire filling method, the amount of the necessary adsorbent per necessary adsorption performance can be reduced.

  The first internal fin member 221 has a steam flow path S formed between adjacent heat transfer surfaces, thereby determining the thickness of the coating and the distance between the heat transfer surfaces of adjacent fins. Thus, the steam flow path S can be easily formed. Therefore, when reducing the size of the adsorber, the necessary adsorbent amount per necessary adsorption performance can be determined by determining the steam flow path S.

  Furthermore, since the vapor can flow through the adsorption / desorption layer 220 through the vapor channel S, the adsorption / desorption action speed of the adsorbent 223 can be increased. Thereby, size reduction of an adsorption machine can be achieved.

  Further, the first and second circulating water flow paths 260 and 270 have heat transfer surfaces for promoting heat exchange between the respective heat exchange media and the adsorbent 223 or the refrigerant, and the bent portions are the first. Corrugated first and second external fin members (261, 271) that are joined to the inner surfaces of the second circulating water flow paths 260, 270 are disposed. Since the fin members 261 and 271 function as reinforcing members in the first and second circulating water channels 260 and 270, the first and second circulating water channels 260 and 270 can be formed of thin plates. Further, the adsorber can be downsized by increasing the heat exchange area.

  The airtight container 210, the first and second circulating water flow paths 260 and 270, the first and second inner fin members (221 and 231), and the first and second outer fin members (261 and 271) have thermal conductivity. By using a large metal material, the adsorber can be formed by, for example, integral brazing in a furnace by forming these members with the same metal material. Therefore, the manufacturing cost can be reduced.
