Description

  The present invention relates to an adsorption heat pump.

  In recent years, the importance of technological development for reducing environmental impact, such as prevention of global warming and conservation of energy resources, has been rapidly increasing. Among them, a technology that collects and reuses low-temperature waste heat that has conventionally been discarded because it has no utility value has attracted attention. One such technique is an adsorption heat pump.

  The adsorption heat pump has an evaporator, two adsorbent heat exchangers, and a condenser, and takes advantage of the removal of ambient heat when a refrigerant (adsorbate) such as water or methanol vaporizes. The temperature of the water passing through the piping in the evaporator is lowered. The refrigerant vaporized at this time is adsorbed by the adsorbent disposed in the adsorbent heat exchanger.

  While one adsorbent heat exchanger is used for refrigerant adsorption, the other adsorbent heat exchanger regenerates (drys) the adsorbent. In the adsorbent heat exchanger on the regeneration side, the adsorbent is heated through hot water whose temperature has risen due to waste heat in the heat exchanger to evaporate the refrigerant. The refrigerant vapor separated from the adsorbent is cooled in the condenser, returned to the liquid, and transferred to the evaporator.

  In the adsorption heat pump, an adsorbent heat exchanger that adsorbs refrigerant and an adsorbent heat exchanger that regenerates the adsorbent are switched at regular intervals.

  However, in the above-described adsorption heat pump, since the adsorbent heat exchanger itself is heated or cooled, a heat loss corresponding to the heat capacity of the adsorbent heat exchanger occurs.

  In view of the above, an object of the present invention is to provide an adsorption heat pump that is superior in thermal efficiency compared to the prior art.

  According to one aspect, an evaporator that lowers the temperature of the heat medium passing through the cooling pipe, an adsorber that adsorbs the vapor of the refrigerant generated in the evaporator to a powdery adsorbent, and hot water are supplied, A regenerator that heats and regenerates the adsorbent that has adsorbed the vapor in the adsorber by the heat of the hot water, and a condenser that is supplied with a heat medium and condenses the vapor generated in the regenerator and returns it to a liquid refrigerant And the regenerator is disposed above the adsorber, and the regenerator and the adsorber are provided with an adsorption heat pump having an inclined surface on which the adsorbent slides.

  According to the above aspect, the adsorber and the regenerator are provided with inclined surfaces. As a result, the adsorbent moves by gravity on the inclined surfaces of the adsorber and the regenerator. The adsorbent adsorbs the vapor while it is positioned on the inclined surface of the adsorber, and is regenerated while it is positioned on the inclined surface of the regenerator.

  In the above-described adsorption heat pump, an apparatus for moving the adsorbent in the adsorber and the regenerator is unnecessary. Further, since the adsorber only adsorbs vapor and the regenerator only regenerates the adsorbent, there is little heat loss.

FIG. 1 is a schematic diagram illustrating an example of a general adsorption heat pump. FIG. 2 is a schematic diagram of the adsorption heat pump according to the embodiment. FIG. 3 is a schematic perspective view of the adsorber. 4A and 4B are schematic views showing examples of valves.

  Hereinafter, before describing the embodiment, a preliminary matter for facilitating understanding of the embodiment will be described.

  FIG. 1 is a schematic diagram illustrating an example of a general adsorption heat pump. As shown in FIG. 1, the adsorption heat pump 10 includes an evaporator 11, a condenser 12, and adsorbent heat exchangers 13 and 14. The evaporator 11 and the adsorbent heat exchangers 13 and 14 are connected via valves 15a and 15b, respectively. The condenser 12 and the adsorbent heat exchanger 13 and 14 are connected via valves 16a and 16b, respectively. Has been. The space in the adsorption heat pump 10 is depressurized by a vacuum device (not shown).

  Inside the evaporator 11, there are provided a cooling pipe 21 and a spray nozzle (not shown) for spraying a liquid refrigerant (adsorbate) on the cooling pipe 21. Cooling water for cooling an apparatus to be cooled (for example, a computer or the like) flows through the cooling pipe 21.

  Inside the adsorbent heat exchanger 13, a heat transfer pipe 23a through which a heat medium passes is arranged. The adsorbent heat exchanger 13 is filled with an adsorbent 29 such as silica gel so as to fill the heat transfer pipe 23a. Similarly, a heat transfer pipe 23b through which a heat medium passes is arranged in the adsorbent heat exchanger 14, and an adsorbent 29 such as silica gel is filled so as to fill the heat transfer pipe 23b.

  A cooling pipe 22 is provided in the condenser 12. Cooling water is supplied to the cooling pipe 22 from a water supply device (not shown), and a gaseous refrigerant is condensed into a liquid as will be described later. The condenser 12 and the evaporator 11 are connected by a pipe 25, and the refrigerant that has become liquid in the condenser 12 is transferred to the evaporator 11 through the pipe 25 and sprayed from the spray nozzle.

  Hereinafter, the operation of the adsorption heat pump described above will be described. Here, first, as shown in FIG. 1, both the valve 15a between the evaporator 11 and the adsorbent heat exchanger 13 and the valve 16b between the adsorbent heat exchanger 14 and the condenser 12 are opened. Suppose that it is in a state. Further, it is assumed that the valve 15b between the evaporator 11 and the adsorbent heat exchanger 14 and the valve 16a between the adsorbent heat exchanger 13 and the condenser 12 are both closed. Further, here, water is used as the refrigerant (adsorbate).

  Cooling water used for cooling is supplied from the cooling target device to the cooling pipe 21 of the evaporator 11. When water is sprayed onto the cooling pipe 21 from the spray nozzle, since the inside of the evaporator 11 is depressurized, the sprayed water easily evaporates (vaporizes) on the peripheral surface of the cooling pipe 21 or in the vicinity thereof. Takes latent heat (heat of vaporization) from 21. Thereby, the temperature of the cooling water flowing through the cooling pipe 21 is lowered, and the low-temperature cooling water is discharged from the cooling pipe 21. This cooling water returns to the cooling target device and is used for cooling the cooling target device.

  The water vapor (gaseous refrigerant) evaporated in the evaporator 11 enters the adsorbent heat exchanger 13 via the valve 15a in an open state. At this time, for example, normal temperature cooling water is supplied to the heat transfer pipe 23a in the adsorbent heat exchanger 13 as a heat medium. The water vapor that has entered the adsorbent heat exchanger 13 is adsorbed by the adsorbent 29. When water vapor is adsorbed by the adsorbent 29, heat of adsorption is generated. This heat is transmitted to the cooling water passing through the heat transfer pipe 23a, and as a result, the temperature of the cooling water passing through the heat transfer pipe 23a rises.

  While the adsorption process for adsorbing the gaseous refrigerant generated from the evaporator 11 is performed in one adsorbent heat exchanger 13, the adsorbent 29 is regenerated (dried) in the other adsorbent heat exchanger 14. The agent regeneration process is performed. That is, hot water whose temperature has increased due to waste heat is supplied to the heat transfer pipe 23b of the adsorbent heat exchanger 14 as a heat medium. The adsorbent 29 is heated by the warm water, and the moisture adsorbed on the adsorbent 29 becomes gas (water vapor) and is separated from the adsorbent 29. The water vapor generated in the adsorbent heat exchanger 14 enters the condenser 12 through the open valve 16b.

  For example, normal temperature cooling water is supplied to the cooling pipe 22 in the condenser 12. As this cooling water, the cooling water discharged from the heat transfer pipe 23a of the adsorbent heat exchanger 13 may be used. The water vapor that has entered the condenser 12 is condensed on the peripheral surface of the cooling pipe 22 or in the vicinity thereof to become water (liquid). Then, this water is transferred to the evaporator 11 via the pipe 25 and sprayed to the cooling pipe 21 from the spray nozzle.

  The valves 15 a, 15 b, 16 a, and 16 b are reversed in the open / closed state according to a signal output from a timer (not shown) at regular intervals. At the same time, the hot water supplied to the adsorbent heat exchanger 14 is supplied to the heat transfer pipe 23a of the adsorbent heat exchanger 13, and the adsorbent heat exchange is supplied to the heat transfer pipe 23b of the adsorbent heat exchanger 14. The cooling water that has been supplied to the vessel 13 is supplied. In this way, the adsorption heat exchangers 13 and 14 alternately perform the adsorption process and the regeneration process at regular time intervals.

  By the way, in the adsorption heat pump 10 mentioned above, since the adsorbent heat exchangers 13 and 14 themselves are cooled or heated, the thermal efficiency is poor. Therefore, in place of the adsorbent heat exchangers 13 and 14 as shown in FIG. 1, an adsorber that only adsorbs the refrigerant and a regenerator that only regenerates the adsorbent are provided to adsorb the powdery adsorbent. It is conceivable to continuously perform adsorption and regeneration by circulating between the regenerator and the regenerator.

  However, since the time required for the refrigerant vapor to be adsorbed by the adsorbent is different from the time required for regenerating (drying) the adsorbent, the thermal efficiency is sufficient by simply circulating the adsorbent. Absent. Further, when the mechanism for circulating and moving the adsorbent becomes complicated, a large amount of energy is consumed for circulating and moving the adsorbent, and as a result, energy saving may not be achieved.

  Hereinafter, embodiments will be described.

(Embodiment)
FIG. 2 is a schematic diagram of the adsorption heat pump according to the embodiment. As shown in FIG. 2, the adsorption heat pump 30 of this embodiment includes an evaporator 31, a condenser 32, an adsorber (heat exchanger) 33, a regenerator (heat exchanger) 34, and an adsorbent storage. Tanks 35, 36, and 37. The space in the adsorption heat pump 30 is decompressed to about 0.6 kPa to 6.0 kPa, for example, by a vacuum device (not shown).

  Inside the evaporator 31, there are provided a cooling pipe 41 and a spray nozzle (not shown) for spraying a liquid refrigerant (adsorbate) such as water or methanol onto the cooling pipe 41. Cooling water (heat medium) used for cooling an apparatus to be cooled (for example, a computer or the like) is supplied to the cooling pipe 41.

  When the coolant is sprayed onto the cooling pipe 41, the inside of the evaporator 32 is depressurized, so that the coolant is easily evaporated into a gas. This gas enters the adsorber 33 through a communication part 45 that communicates between the evaporator 32 and the adsorber 33.

  The adsorber 33 is provided with a cooling pipe 43. For example, normal temperature cooling water is supplied to the cooling pipe 43 from a water supply device (not shown). The adsorber 33 is provided with an inclined surface at an angle at which the powdery adsorbent 39 slides down.

  The regenerator 34 is disposed above the adsorber 33. The regenerator 34 is provided with a hot water pipe 44 through which hot water whose temperature has increased due to waste heat passes. The regenerator 34 is also provided with an inclined surface at an angle at which the powdery adsorbent 39 slides down as in the adsorber 33. While the adsorbent 39 slides down the inclined surface, the adsorbent 39 is heated by the hot water passing through the hot water pipe 44, and the refrigerant adsorbed on the adsorbent 39 is evaporated to become a gas. This gas enters the condenser 32 through a communication portion 46 that communicates between the regenerator 34 and the condenser 32.

  A cooling pipe 42 is disposed in the condenser 32. For example, room temperature cooling water is supplied to the cooling pipe 42. As this cooling water, the cooling water discharged from the adsorber 33 may be used. The refrigerant that has become a gas in the condenser 32 is cooled by the cooling water passing through the cooling pipe 42 and condensed to become a liquid. The refrigerant that has become the liquid is transferred to the evaporator 31 via the pipe 39 and sprayed into the evaporator 31.

  The inlet side (the upper end side of the inclined surface) of the regenerator 34 is connected to the storage tank 35 via a valve 48a. When the valve 48a is opened, the adsorbent 39 is supplied from the storage tank 35 onto the inclined surface of the regenerator 34 by gravity. The outlet side of the regenerator 34 (the lower end side of the inclined surface) is connected to the storage tank 36 via a valve 48b. The adsorbent 39 discharged from the regenerator 34 enters the storage tank 36 via the valve 48 b and is temporarily stored in the storage tank 36. The time (average time) during which the adsorbent 39 stays on the inclined surface of the regenerator 34 varies depending on the opening degree of the valves 48a and 48b.

  The inlet side (upper end side of the inclined surface) of the adsorber 33 is connected to the bottom of the storage tank 36 via a valve 47a. When the valve 47a is opened, the adsorbent 39 is supplied from the storage tank 36 onto the inclined surface of the adsorber 33 by gravity. The outlet side (lower end side of the inclined surface) of the adsorber 33 is connected to the storage tank 37 via a valve 47b. The adsorbent 39 discharged from the adsorber 33 enters the storage tank 37 via the valve 47 b and is temporarily stored in the storage tank 37. The time (average time) during which the adsorbent 39 stays on the inclined surface of the adsorber 33 varies depending on the opening degree of the valves 47a and 47b.

  Between the storage tank 37 and the storage tank 35, an adsorbent transport device 38 that transports the adsorbent 39 from the storage tank 37 to the storage tank 35 is provided. As the adsorbent transport device 38, for example, a screw pump in which a spiral transport conveyor is inserted into a pipe can be used.

  For the adsorbent 39, silica gel, zeolite, activated carbon, or the like can be used. In this embodiment, since the regeneration is possible at a relatively low temperature (for example, about 50 ° C. to 60 ° C.), activated carbon is used as the adsorbent 39. Further, the shape of the adsorbent 39 is assumed to be spherical so that the inclined surfaces of the adsorber 33 and the regenerator 34 can easily slide down.

  It should be noted that what kind of adsorbent 39 is to be used is appropriately determined depending on the temperature of the cooling water supplied to the evaporator 31, the adsorber 33 and the regenerator 34, the temperature of the hot water supplied to the regenerator 34, and the like. Good.

  FIG. 3 is a schematic perspective view of the adsorber 33. As shown in FIG. 3, a plurality of strip-shaped cooling pipes 43 through which cooling water passes are arranged in the adsorber 33 in parallel with the direction in which the adsorbent 39 slides down. The adsorber 33 is covered with an aluminum mesh sheet lid 33a (see FIG. 2) so that the adsorbent 39 is not dissipated out of the adsorber 33.

  Similarly, a plurality of strip-shaped hot water pipes 44 through which the hot water whose temperature has increased due to waste heat passes are arranged in the regenerator 34 in parallel to the direction in which the adsorbent 39 slides down. The regenerator 34 is covered with an aluminum mesh sheet lid 34a (see FIG. 2) so that the adsorbent 39 is not dissipated out of the regenerator 34.

  FIG. 4A is a schematic top view illustrating an example of the valves 47a, 47b, 48a, and 48b. FIG. 4B is a schematic side view showing another example of the valves 47a, 47b, 48a, 48b.

  The valve shown in FIG. 4A is formed by two doors 51 that are driven by a driving device to open and close in the left-right direction, and the valve shown in FIG. 4B is formed by a shutter 52 that moves in the up-down direction. It is a thing.

  A valve as shown in FIGS. 4A and 4B is more preferable than a valve that completely closes the flow path, such as a rotary valve, because it hardly inhibits the flow of the adsorbent 39 when opening and closing. The opening degree of the valves 47a, 47b, 48a, 48b is preferably adjusted as appropriate according to the temperature of hot water supplied to the regenerator 34.

  Hereinafter, the operation of the adsorption heat pump 30 according to the present embodiment will be described with reference to FIG. Here, water is used as the refrigerant (adsorbate).

  The cooling water used for cooling is supplied to the cooling pipe 41 of the evaporator 31 from the cooling target device. Here, the temperature of the cooling water supplied to the evaporator 31 is about 20 ° C. to 25 ° C.

  When water is sprayed onto the cooling pipe 41 from the spray nozzle, the inside of the evaporator 31 is depressurized. Therefore, the sprayed water evaporates (vaporizes) on the peripheral surface of the cooling pipe 41 or in the vicinity thereof, and latent heat is generated from the cooling pipe 41. Take away. Thereby, the temperature of the cooling water flowing through the cooling pipe 41 is lowered, and the cooling water at a low temperature (for example, about 18 ° C.) is discharged from the cooling pipe 41. This cooling water returns to the cooling target device and is used for cooling the cooling target device.

  The water vapor (gaseous refrigerant) evaporated in the evaporator 31 enters the adsorber 33 through the connecting portion 45 and is adsorbed by the adsorbent 39 in the adsorber 33. When water vapor is adsorbed by the adsorbent 39, it changes to water (liquid), and heat corresponding to the heat of vaporization is generated. This heat is transmitted to the cooling water passing through the cooling pipe 43, and as a result, the temperature of the cooling water passing through the cooling pipe 43 rises. Here, it is assumed that water at room temperature (for example, 25 ° C.) is supplied to the cooling pipe 43 as cooling water.

  The adsorbent 39 that has slid down the inclined surface in the adsorber 33 enters the storage tank 37 via the valve 47 b and is conveyed to the upper storage tank 35 by the adsorbent conveyance device 38. And it moves on the inclined surface of the regenerator 34 through the valve 48a.

  The hot water pipe 44 of the regenerator 34 is supplied with hot water whose temperature has increased due to waste heat (for example, hot water of about 50 ° C. to 60 ° C.). The adsorbent 39 is heated by the warm water, and the moisture adsorbed on the adsorbent 39 becomes gas (water vapor) and is detached from the adsorbent 39. The water vapor generated in the regenerator 34 enters the condenser 32 through the communication unit 46.

  For example, room-temperature cooling water is supplied to the cooling pipe 42 in the condenser 32. As this cooling water, the cooling water discharged from the adsorber 33 may be used. The water vapor that has entered the condenser 32 is condensed on the peripheral surface of the cooling pipe 42 or in the vicinity thereof to become water (liquid). Then, this water is transferred to the evaporator 31 via the pipe 39 and sprayed to the cooling water coil 41 from the spray nozzle.

  On the other hand, the adsorbent 39 regenerated (dried) by the regenerator 34 enters the storage tank 36 via the valve 48b. And it is further sent to the adsorber 33 through the valve 47a, and adsorbs water vapor while moving on the inclined surface of the adsorber 33. The adsorbent 39 having adsorbed water vapor by the adsorber 33 enters the storage tank 37 via the valve 47 b and is sent to the storage tank 35 by the transport device 38. Then, it is further supplied onto the inclined surface of the regenerator 34 through the valve 48 a and regenerated (dried) by the regenerator 34.

  By the way, as described above, the adsorbent 39 is regenerated by being heated by the heat of the hot water passing through the hot water pipe 44 while staying on the inclined surface of the regenerator 34. However, if the adsorbent 39 stays on the inclined surface of the regenerator 34 is too short, the adsorbent 39 is sent to the adsorber 33 without being fully regenerated. If the adsorbent 39 stays on the inclined surface of the adsorber 33 for too long, the amount of refrigerant adsorbed on the adsorbent 39 is saturated and no further adsorption is performed.

  Therefore, in order to operate the adsorption heat pump 30 continuously and efficiently, the amount of the adsorbent 39 regenerated per unit time by the regenerator 34 and the amount of the adsorbent 39 used for adsorption by the adsorber 33 are determined. It is important to balance usage per unit time. The amount of the adsorbent 39 regenerated per unit time in the regenerator 34 includes the opening degree of the valves 48a and 48b, the type of the adsorbent 39, the temperature of the hot water supplied through the hot water pipe 44, and the adsorbent 39 and the hot water pipe 44. Related to the contact area and the like. The amount of the refrigerant adsorbed per unit time by the adsorber 33 is related to the opening degree of the valves 47a and 47b, the type of the adsorbent 39, the contact area of the adsorbent 39 and the cooling pipe 43, and the like.

(Experiment 1)
As a heat exchanger (adsorber and regenerator), a box-shaped member made of a copper plate having a length of 24 cm, a width of 12 cm, and a depth of 3 cm (both are internal dimensions) was prepared. A plurality of heat medium tubes having a width of 2 mm extending in the length direction of the heat exchanger are arranged inside the heat exchanger at intervals of 6 mm in the width direction. Moreover, the aluminum mesh sheet which covers this heat exchanger was prepared.

  The inside of this heat exchanger is filled with 200 g of spherical activated carbon (A-BAC MP: manufactured by Kureha Co., Ltd.) having a particle diameter of about 0.5 mm as an adsorbent, and the angle at which the activated carbon begins to slide when the heat exchanger is tilted Was measured. As a result, it was confirmed that if the heat exchanger is inclined at an angle of 5 ° or more, the activated carbon slides down the inclined surface. However, if the inclination angle is larger than 45 °, the adsorbent concentrates on the lower part of the inclined surface, and the adsorption efficiency and the regeneration efficiency are deteriorated.

  For these reasons, in the adsorption heat pump 30 according to the embodiment, the inclination angle of the inclined surfaces of the adsorber 33 and the regenerator 34 is in the range of 5 ° to 45 °.

(Experiment 2)
The adsorption rate and regeneration rate of the adsorbent were measured using the heat exchanger and adsorbent used in Experiment 1. As a result, it was found that regeneration of the adsorbent was almost completed in about 2 minutes. It was also found that the adsorption of water vapor takes about 4 minutes.

  For these reasons, in the adsorption heat pump 30 according to the embodiment, the area of the surface of the adsorber 33 that contacts the adsorbent 39 is twice the area of the surface of the regenerator 34 that contacts the adsorbent 39 and The flow rate of the cooling water flowing to the vessel 33 was twice as much. Thereby, it becomes easy to balance the adsorption time by the adsorber 33 and the regeneration time by the regenerator 34, and the adsorption heat pump 30 can be operated continuously and efficiently.

  As described above, the adsorptive heat pump 30 according to the embodiment includes the adsorber 33 that only adsorbs the refrigerant and the regenerator 34 that only regenerates the adsorbent 39. Therefore, the adsorptive heat pump 10 shown in FIG. Thermal efficiency is better than Therefore, the apparatus can be miniaturized, can be widely used in various apparatuses that generate waste heat, and can contribute to the reduction of environmental load. In the adsorption heat pump 30 according to the embodiment, the adsorbent 39 is moved between the storage tank 35 and the storage tank 37 (regenerator 34 -storage tank 36 -adsorber 33 -storage tank 37) using gravity. I am letting. For this reason, less energy is required for circulating the adsorbent 39.
