Description

  The present invention relates to a desiccant air conditioner using a hygroscopic porous particle as a medium, and in particular, an adsorption refrigerator that can be efficiently operated as an entire air conditioning system by being combined with an adsorption refrigerator. The present invention relates to a combined desiccant air conditioning method and an apparatus for carrying out the method.

  Development of effective utilization technology of low-temperature thermal energy of 800 ° C or less that can be easily obtained by exhaust heat or solar heat in chemical processes is a major problem in modern society, such as reduction of carbon dioxide emissions, heat island phenomenon, fluctuations in summer power demand, etc. This is one of the important issues in addressing environmental conservation issues or energy issues. On the other hand, one of the existing technologies considered to be effective is a desiccant air conditioning system using a desiccant having a high water absorption / desorption property.

  In a desiccant air-conditioning system that has been put into practical use, the processing process and the regeneration process are performed in a face-to-face manner as shown in FIG. That is, a dehumidification rotor 101 coated with a desiccant (desiccant) and a sensible heat exchange rotor 102 are arranged in series, and dehumidification and heat exchange of environmental air introduced to the processing side are sequentially performed. The water spray 103 is disposed downstream of the sensible heat exchange rotor 102, and water is sprayed onto the medium-temperature / low-humidity air to remove the heat of vaporization of the water, so that the air becomes low-temperature / high-humidity.

  On the other hand, in the regeneration process, the indoor air of high temperature and high humidity is taken in, converted into low temperature and high humidity air by the evaporative cooler 104, and sent to the sensible heat exchange rotor 102. The sensible heat exchange rotor 102 that has reached a high temperature on the processing side is cooled by the medium temperature and high humidity air. Further, the air heated by the sensible heat exchange rotor 102 and heated to a higher temperature is further heated by the heater 105. Various heaters can be used as the heat source of the heater 105. The dehumidification rotor 101 is heated by this high-temperature air, the moisture on the dehumidifier is evaporated, and the dehumidifier is regenerated.

  In the desiccant air conditioning system as described above, the two rotors have a honeycomb shape, and contact with the air is favorably performed. By rotating at a low speed, the processing steps and the regeneration process can be performed simultaneously, and packaging has been successful and commercialized. Such a desiccant air conditioner is described in, for example, Japanese Patent Application Laid-Open No. 2003-35434.

  In such a conventional desiccant air conditioner, since the desiccant (adsorbent) is held by a rotor formed of a honeycomb-shaped carrier and is rotated integrally, dehumidification and regeneration must be performed at the same time. For this reason, there is a limit to the dehumidifying capacity, and there is a problem that the size cannot be reduced unless the heat supply and the dehumidifying demand match. In addition, a heating heat source is required at the time of dehumidification regeneration of the desiccant that has absorbed moisture, and there is also a problem that efficiency is deteriorated by consuming energy.

  In order to solve the above problems, the present inventor can easily cope with the imbalance between the heat supply and the dehumidification demand, and reduces the cooling load by dehumidification, especially for the consumer use that is usually fixed. A small desiccant air conditioner has been developed and a patent application has been filed so as to reduce the energy consumption required for air conditioning in the space around the equipment by utilizing waste heat from various equipment (Patent Document 2). .

This small desiccant air conditioner is as shown in FIG. 9. In the dehumidifier 115, the air in the room 113 is introduced by the blower 116, and is dehumidified by the dry porous particles flowing down on the dispersion plate 117. The heat exchanger 120 is set to a predetermined temperature, is appropriately humidified by the humidifier 128, and is supplied into the room from the blower 121. Particles that have flowed down the dispersion plate 117 and adsorbed moisture in the room air enter the regenerator 122 from the particle reservoir 118 and are heated by the heat exchanger 121 using exhaust heat from various consumer devices such as the consumer cogeneration device 123. The adsorbed moisture is desorbed and regenerated. The regenerated adsorbent particles are sucked by the vacuum pump 126 and conveyed to the particle reservoir 111. The exhaust from the vacuum pump 126 is appropriately used as combustion air for consumer equipment.

  With the air conditioner as described above, it has become possible to reduce energy consumption by dealing with the imbalance between heat supply and dehumidification demand and using waste heat from various consumer devices. In this apparatus, the particles that have been dehumidified by the dehumidifier 115 are stored in the particle reservoir 118 and then immediately sent to the regenerator 122 to regenerate the particles. Therefore, the dehumidifier 5 performs the dehumidifying action. Despite the fact that there are still many particles with sufficient dehumidifying capacity, the particles were regenerated as they were, and the dehumidifying capacity of the particles was not fully utilized.

  Further, including those using the rotor, the capacity is insufficient when the outside air is at high temperature and high humidity, or the amount of dehumidification is low at high temperature and low humidity, so the air conditioning capacity is insufficient, and it is necessary to add a cooling source separately. In addition, the need to perform adiabatic dehumidification was a cause of insufficient dehumidification capacity. Furthermore, it is necessary to dry the rotor by adiabatic drying for particle regeneration, and the required air volume is enormous and the exhaust power is required to be about the same as the supply air.

  Therefore, in the desiccant air-conditioning system, the present invention enhances the air-conditioning function by combining an adsorption refrigeration machine, provides a cooler in the dehumidifying section, enables isothermal dehumidification, and further conducts conductive heating drying to regenerate the dehumidifying agent.

  Since the present invention is configured as described above, in the desiccant air conditioner, an adsorption type refrigerator can be combined to fully utilize the dehumidification surplus of the particles, and the desiccant air conditioner can be made efficient as a whole. In addition, since the temperature can be lowered, the air conditioning capacity does not decrease even at high temperatures and high humidity, and the lack of cooling capacity of the desiccant air conditioner can be solved. Further, the conventional rotor type desiccant air conditioner is used only for dehumidification and often requires a separate refrigerator, but it is easy to be introduced as a single air conditioner due to the enhanced temperature control function.

In the particle circulation type desiccant air-conditioning system, the adsorption-type refrigerator is combined to sufficiently utilize the dehumidification surplus capacity of the particles, so that the desiccant air-conditioning system is efficient as a whole. Then, the particles extracted from the lower portion of the duct are introduced into an adsorption refrigerator, and the vapor in the evaporation chamber of the adsorption refrigerator is adsorbed by the residual adsorption capacity of the particles, The dehumidified air is cooled in the duct by cooling water generated at a low temperature generated by the adsorption of steam.
At that time, when the moisture in the air in the duct is adsorbed and dehumidified by the dehumidifying agent particles, isothermal dehumidification can be performed by cooling with cooling water from a cooling water supply source.

  Embodiments of the present invention will be described with reference to the drawings. FIG. 1 schematically shows an embodiment of a particle circulation type desiccant air conditioner according to the present invention. In the example of FIG. 1A, an intake air cooling heat exchanger 4 that cools the intake air with cooling water from a cooling tower or the like between the air intake port 2 and the dehumidified air outlet 3 of the air supply duct 1. , A dehumidifying unit 5 that adsorbs moisture in the air flowing through the duct by free-falling or slowly dropping particles from above the air supply duct, heat exchange for dehumidified air cooling that cools the dehumidified air with cooling water as described later The example which has arrange | positioned the apparatus 6 in order is shown.

  In the desiccant air conditioner shown in the figure, desiccant particles for supplying air dehumidification are ducted from a dry particle supply storage tank 7 as a particle supplying unit through a particle supply port 8 disposed above the dehumidifying unit 5 of the air supply duct 1. Descent in. In that case, the particles are allowed to fall freely, and moisture in the air flowing in the air supply duct is adsorbed while being kept at a constant temperature by a dehumidifying part cooler 27 as shown in FIG. It is done. When the particles are allowed to fall freely in the duct in this way, for example, the distribution plate 17 as shown in FIG. 4 is caused to flow down, and the pressure loss that greatly reduces the air flow resistance is reduced as compared with the method of dehumidifying through the air. be able to. Therefore, the pressure loss of the supply air can be sufficiently reduced with a simple structure as compared with other conventionally proposed contact dehumidification methods of various particles and air.

  Since the particles fall freely in the dehumidifying section 5, they can be surrounded by a partition wall 19 that allows only air, such as a wire mesh, to pass therethrough so that the fine particles are not supplied into the room and are not scattered to the other. preferable. Since only about 1 to 20% of moisture is adsorbed to the particles collected in the lower part of the air supply duct 1 in this way, there is still sufficient moisture adsorption capacity. Therefore, the particles are sent to the evaporator of the adsorption refrigeration machine 12 through the supply pipe 11 provided with the supply side valve 10 in the figure and used.

  As the adsorption refrigerator 12, various well-known devices using a condenser of an evaporator can be used. For example, the water vapor generated by adsorbing water vapor in the container by the adsorbent particles supplied into the container is used. An adsorption refrigerator that performs the action of cooling the water evaporation portion due to the evaporation promoting effect of can be used. Therefore, also in this embodiment, using this action, an evaporation heat exchanger 13 is provided in the evaporator of the adsorption refrigeration machine 12 so that the water flowing inside can be cooled, and the obtained cooling water can be supplied elsewhere. Yes.

  In the illustrated embodiment, the cooling water is circulated between the dehumidified air cooling heat exchanger 6 provided on the dehumidified air outlet 3 side of the air supply duct 1. As a result, after the moisture in the air is adsorbed as described above, the particles still having the ability to adsorb moisture are supplied from the supply pipe 11 to the adsorption refrigerator 12 to adsorb the water vapor in the internal space and evaporate. The water around the evaporating heat exchanger 13 acting as a cooler is evaporated, the water flowing in the evaporating heat exchanger 13 is cooled, and supplied to the dehumidified air cooling heat exchanger 6. As a result, the air supplied to the room in the air supply duct 1 is cooled to reduce the cooling load. Further, the cooling water whose air has been cooled by the heat exchanger 6 for cooling the dehumidified air is returned to the evaporation heat exchanger 13 of the adsorption refrigerator 2 and circulated again.

  By constructing a system that uses the adsorption capacity of such moisture adsorption particles, supply the cooling water by using the particles still having sufficient moisture adsorption capacity after dehumidifying the air in the duct for water vapor adsorption of the adsorption refrigerator. The cooling water can be used for cooling the dehumidified air and can be used for cooling the air supplied to the room, so that an efficient air conditioner can be obtained. In particular, in this desiccant air conditioner, after the moisture in the duct is adsorbed by the particles, the temperature rises due to the heat of adsorption. Therefore, it is preferable to cool the air. Provide downstream of the air flow.

  In the adsorption refrigeration machine 12, in particular, the water around the evaporating heat exchanger 13 is sufficiently adsorbed, and the particles having almost no water adsorption capacity are removed from the discharge pipe 15 provided with the discharge side valve 14 in the figure. 16 is supplied. If necessary, the particle regenerator 16 is provided with a heater 17 that uses waste heat that is no longer necessary in the external system, as in the conventional example of FIG. 4, and adsorbs moisture by raising the temperature of the particles. Release and regenerate the adsorption capacity of the particles. The water released in this way is condensed in the condenser 18, and the condensed water is returned to the evaporating heat exchanger 13 and used as the moisture for adsorption by the particles having the above-mentioned adsorption capacity. A part of the cooling water obtained by the evaporating heat exchanger 13 can be used as a cooling heat source for the condenser 18.

  Furthermore, since the temperature of the particles that have adsorbed moisture in the adsorption refrigerator 12 rises, the portion where the particles are stored becomes high temperature. Therefore, a heat exchanger through which the fluid flows is provided in that part, and the heat of the particles is removed to improve the adsorption efficiency, and the fluid whose temperature has been raised is led to the heat exchanger in the particle regenerator 16 to be circulated, It can be used as a heat source for heating particles in the particle regenerator 16. In particular, when the adsorption refrigeration machine 12 and the particle regenerator 16 can be arranged close to each other, the heat generated by moisture adsorption in the adsorption refrigeration machine 12 can be used as heat for regeneration in the particle regenerator 16 as it is. And it can be set as an efficient apparatus.

  Moreover, since the adsorption capacity by the particles in the adsorption unit 5 is higher when the temperature of the particles is lower, the dried particles that have become hot due to the regeneration are replaced with a regenerative particle cooling heat exchanger that takes in the low-temperature indoor air. It may be cooled by exchanging heat with room air and supplied to the dry particle supply storage tank 7. Or you may cool with the cooling water from a cooling tower. In supplying such dry particles, it is possible to use an air transportation method in which the particles are transported in an air stream, a suction method using a vacuum pump, or various mechanical transportation means such as conveyor transportation and packet transportation.

  When the adsorption refrigerator 12 is provided with two discharge side valves 14 and 14 ′ in the same manner as the pair of supply side valves 10 and 10 ′ as shown in the figure, these are used as lock hoppers. The vacuum pump (not shown) is operated with both valves closed to lower the internal pressure. When the same pressure as in the adsorption refrigerator 12 is reached, the supply valve 10 ′ is opened to supply particles into the 12. Further, when the pressure on the discharge valve side becomes the same as that in the inside, 14 'is opened and the particles are extracted. As a result, the evaporation heat exchanger is evaporated at a low pressure, and thus has a high evaporation capability, can generate low-temperature cooling water, and can effectively cool the air conditioner. After performing this action, the operation of operating the lock hopper to refill and withdraw particles from the adsorption refrigerator 12 is repeated.

  In the above-described embodiment, an example in which particles are freely dropped while the air supply duct 1 is disposed horizontally is shown, but the air supply duct 1 can be implemented even when installed in an appropriate inclined state. Further, in the air supply duct 1 arranged horizontally, air may be supplied by an appropriate inclined body and allowed to fall freely.

  FIG. 1B shows another embodiment, in which the evaporation chamber of the adsorption refrigerator 12 and the bottom opening 22 of the regenerator 16 are connected by an air supply pipe 20, and a blower 24 is provided in the air supply pipe 20. An air outlet 23 is provided at the bottom of the regenerator 16. In such an apparatus, when the blower 24 is driven and air that has passed through the particles that have become high temperature and low humidity due to moisture adsorption at the bottom of the regenerator 16 is blown from the bottom of the regenerator 16 at a high speed, the regenerator 16. The particles inside are fluidized and come into contact with the high-temperature air blown by the fluidized body to efficiently exchange heat. When operating such a system, an air supply port 21 is provided in the adsorption refrigerator 12 and a discharge port 25 is provided in the regenerator 16 as necessary.

  In the system shown in FIG. 1, it is possible to make a system that can fully utilize the dehumidification surplus of the particles by combining the adsorption refrigerator, but as shown in FIG. If an isothermal dehumidification can be performed by providing the dehumidifying part cooler 27 that cools with cooling water from a cooling water supply source, a more efficient adsorption refrigeration combined desiccant air conditioning system can be obtained.

  That is, in the example shown in FIG. 2, the cooling water after cooling by the separately provided cooling tower 26 is taken in and supplied to the air cooling heat exchanger 4 as in the example of FIG. Further, a dehumidifying part cooler 27 is provided in the dehumidifying part 5 that adsorbs moisture in the air flowing through the duct by allowing particles to freely fall or slowly descend from above the air supply duct, and the dehumidifying part cooler 27 is also supplied with cooling water. Supplying it enables isothermal dehumidification. Such isothermal dehumidification is widely known to perform dehumidification with higher efficiency than adiabatic dehumidification, and the apparatus shown in FIG. 2 can perform such isothermal dehumidification. It is also possible to further accelerate the dehumidification rate than the isothermal dehumidification. In the above example, the cooling is performed by using a cooling tower, but a vapor compression refrigerator, an absorption refrigerator, an adsorption refrigerator, or the like provided separately can also be used.

  In the example shown in FIG. 3, the cooling water obtained by the adsorption refrigeration machine 12 is supplied to the dehumidifying section cooler 27 so that the isothermal dehumidification can be performed in the same manner as described above. In this example, a heat exchanger 4 ′ for regenerated particle cooling is provided, and a heat exchanger 28 for cooling dry particles is further provided in the dry particle supply storage tank 7. In this example, the regenerated particle cooling heat exchanger 4 ′ is provided in the middle of the regenerated particle return line, so that the regenerated particles are cooled while being sent to the dry particle supply storage tank 7, and the dry particles in the dry particle supply storage tank 7 are further dried. The particle cooling heat exchanger 28 further cools using the cold generated in the adsorption refrigerator 12.

  By using such a particle cooling device, the adsorption capacity by the particles in the adsorption unit 5 is higher when the temperature of the particles is lower. Therefore, the dried particles that have become hot due to regeneration are cooled and adsorbed as described above. I am raising my ability. In the cooling of the regenerative particle cooling heat exchanger 4 ′, the regenerative particle cooling heat exchanger 4 ′ may be cooled using cold heat from the cooling tower 26 as shown in FIG. 2. In the example shown in FIG. 3 as well, the dehumidifying part cooler 27 is provided in the same manner as in the example of FIG. 2. However, in the example of FIG. 3, the dehumidifying part cooler 27 uses the cold generated by the adsorption refrigerator. Shows an example of cooling.

  As another example, FIG. 4 shows an example in which exhaust air from room air is used as a heater 17 for regeneration in the particle regenerator 16, and a conductive heater 17 'is provided. Although various things can be used as the conduction heater 17 ', for example, as described above, external exhaust heat can be used, and a heat exchanger or the like for supplying hot water or heating steam may be disposed. . Moreover, you may use an electric heater as needed.

  In this way, the necessary air volume for particle regeneration is reduced by using conductive heating in combination with the regeneration section, and it is not necessary to use the entire amount of exhaust from the room 49 as regeneration air. The power consumption of the exhaust fan 30 that is necessary to some extent can be cut off. As a result, the exhaust fan 30 that operates with low power consumption, such as natural exhaust or a ventilation fan, can be used for indoor exhaust. Furthermore, by arranging the exhaust pipe so that the exhaust from the room is mixed with the high-temperature exhaust exhausted from the dehumidifying agent regeneration unit, the exhaust fan is unnecessary, or only a very small exhaust fan is used, reducing power consumption. You may make it do.

  In FIG. 5, as another example, a humidifier 51 and a low pressure loss heat exchanger 52 such as a fin plate or a heat pipe are provided in this order in the outlet duct 53 of the exhaust fan 30 that exhausts the air in the room 49. In the example shown in FIG. 5, the water cooled by the cooling tower 26 can be further cooled by the cooler 53 in the example shown in FIG. 5 by the low temperature and the heat of vaporization by the humidifier. In the heat exchanger 4 for use and the dehumidifying part cooler 7, the cooling can be performed at a lower temperature.

  In the above-described embodiment, an example in which particles are simply dropped freely from above in the air supply duct 1 is shown. However, as shown in FIG. 6, for example, a particle supply unit 31 is provided below the air supply duct 1. In addition, a particle conveying device that supplies the particles inside the air supply duct 1 may be provided. In the particle conveying device shown in FIG. 6A, a high-pressure blower 33 is provided in a particle ejection nozzle 32 having a lower end inserted into a particle storage portion in the particle supply unit 31, and the particle ejection nozzle 32 is disposed in the air supply duct 1. In the dehumidifying part 5, it arrange | positions so that it may open toward the upper upper direction of a duct. The lower surface of the particle supply unit 31 can be air circulated to the outside by a breathable member such as a net, and thereby the high-pressure blower 33 is driven to suck particles below the particle supply unit 31 together with air from the outside, thereby supplying an air supply duct. In the 1 dehumidifying part 5, it sprays upwards facing the air flow in a duct.

  The particles ejected from the lower side to the upper side in the dehumidifying part 5 and facing the air flow are in contact with the air flow having a low flow velocity because the cross-sectional area of the dehumidifying part 5 in the air supply duct 1 is large. Naturally falls inside. In the process, the air taken into the air supply duct 1 is dehumidified, and the dehumidified particles fall on the lower surface in the air supply duct. The dropped particles fall from the opening 34 into the adsorption refrigerator 36 in the particle processing unit 35 provided adjacent to the lower part of the air supply duct 1.

  The particle processing unit 35 is divided into four parts as shown in the plan view of (b) shown as the AA partial cross section in FIG. 1, the internal vapor is adsorbed and the adsorption refrigerator 36 is operated, and is then sent to the adjacent regenerator 37 to release and regenerate the adsorbed moisture by heating from the outside. Store in part 38. The stored dry particles are sent to a particle supply chamber 31 as a particle supply unit provided with a particle jet nozzle 32, and sent to the air supply duct 5 by the particle jet nozzle 32 as described above, and are used in a circulating manner. Here, 1W indicates the position of the projection line on the side of the air supply duct at the top.

  In the adsorption refrigeration machine 36, the generated cooling water is supplied to the heat exchanger 6 for cooling the dehumidified air as in the example of FIG. In the regenerator 37, the particles are heated using external waste heat or the like as in the example of FIG. 1, and if necessary, a condenser is provided in the same manner as in the above-described embodiment, and the condensed water is adsorbed by freezing. It can also be returned to the machine. Further, the particles regenerated by the regenerator 27 may be cooled by the regenerative particle cooling heat exchanger 4 as in the above embodiment. In addition, the first shutter 40 is disposed above the adsorption refrigerator 36, and the second shutter 41 is disposed in the communication path between the adsorption refrigerator 36 and the regenerator 37, and this is operated in a lock hopper type. The inside of the adsorption refrigerator 36 may be decompressed to improve the cooling capacity.

  In the example shown in FIG. 6A, an example in which the particle ejection nozzle 32 is provided when the dry particles from the particle supply unit 31 are conveyed above the dehumidifying unit 5 in the air supply duct 1 is shown. As shown in FIG. 6B, a particle injection rotating wheel 45 that injects the particles of the particle supply unit 31 to the upper part of the air supply duct 1 with stirring blades may be used.

  Further, as shown in FIG. 4D, a packet type conveying device 47 for circulating a large number of packets 46 from the particle supply unit 31 to the upper part in the air supply duct 1 is provided, and the dry particles in the particle supply unit 21 are collected. You may comprise so that an internal particle may be scattered in a duct by conveying to the upper part in the air supply duct 1, and inverting a packet in the upper end part.

  Also, as shown in FIG. 5 (e), using a packet-type transfer device 50 in which a wire mesh packet 48 is arranged radially around a rotation shaft 49, the particles of the particle supply unit 31 located at the lower part are collected into a packet, It may be configured such that the particles are dropped from the upper packet to the lower packet by its own weight, dropped to the back side of the wire mesh packet rotating forward, and discharged to the evaporation chamber of the adsorption refrigerator. As described above, various methods can be used as a method for performing dehumidification by allowing particles to freely fall in the air supply duct 1.

  In this embodiment, after dehumidifying the air supply duct with a low resistance to the air flow due to natural fall in the air supply duct, cooling water is generated by using particles that still have the ability to adsorb moisture in the adsorption refrigerator. The cooling water is used to cool the air after dehumidification, and then, when the particles are regenerated and circulated, the particle reservoir is disposed below and the particles are transported above the air supply duct. For this purpose, various particle conveying devices are used. At that time, the adsorption refrigerator 36, the regenerator 37, and the dry particle storage unit 38 are arranged adjacent to each other to form a compact particle processing unit as a whole. be able to. In the example shown in FIG. 6, an example in which the dry particle storage unit 38 and the particle supply unit 31 provided with the particle ejection nozzle 32 are separately provided is shown, but these may be an integral chamber.

  In each of the above-described embodiments, various examples are shown in which the moisture in the air supply duct is lowered from above the duct when adsorbing the moisture in the air supply duct with the dehumidifying agent particles. The above-mentioned embodiment is shown as an easy example, and various other dehumidification methods such as a fluidized bed method already disclosed by the present inventors can also be adopted.

  In this embodiment, it can be carried out in various manners as in the previous embodiment. For example, as shown in FIG. 7, a dehumidifying section cooler 27 for supplying cooling water from the cooling tower 26 is provided. Also, the cooling water can be supplied to the air cooling heat exchanger 4 for cooling the intake air, and the embodiment shown in FIG.
