DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air flow particle conveying apparatus for air flow conveying particles having a size equal to or less than a particle size,
The present invention relates to an air conditioner using air-flow conveyance of heat storage particles such as latent heat storage capsules and granular ice.

[0002]

2. Description of the Related Art Conventional transfer apparatuses related to the present invention are disclosed in JP-A-54-15553, JP-A-52-128272, and
55-107868 and JP-A-61-83850. These conventional conveying devices mechanically convey the granules by a conveyor or a screw, and have a disadvantage that the device is large and the conveying power is easily increased.In addition, the granules are caught in the middle of a conveying system path, It may bite and break down. Further, it does not disclose that the granular ice is sent to a desired place by air conveyance and air conditioning is performed by abusing the direct contact heat exchange method with air.

[0003]

As described above, many of the transfer apparatuses frequently break down due to the particles being caught or bitten on the way. SUMMARY OF THE INVENTION An object of the present invention is to provide an air flow granular material transfer device that can at least eliminate biting failure and detect clogging due to catching, and can easily clear clogging even if it cannot be avoided. . Another object is to provide a high-efficiency air conditioner that transports heat storage particles using the transport device and uses the transport medium as it is. The aim is to obtain conditioned air in a remote and good environment.

[0004]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a bunker and a granule supply path,
Storage at the end of the granule transport path connected to the
In the air conditioner using hot granules,
Sealed around the path, and a preset interval in the middle of the conveyance path
Through a valve that communicates with the high pressure air tank
At the entrance of the granule supply path or the bunker entrance
It is opened and closed to make it airtight, and
Close the pipe to the high pressure gas tank near the downstream side with a valve.
And the carrier air is stored in the granule receiver
Exhausted through the granule receiver while in contact with the thermal storage granules
Is what is done.

[0005]

[0006] When the thermal storage particles are transported, the transport air receives heat during transport, and if it is used as it is as conditioned air, conditioned air can be obtained without a special heat exchanger. A simple heat exchanger is obtained when the air sucked from the outside is brought into direct contact with the heat storage granules stored in the granule receiver and receives heat transfer. If the transportation distance is insufficient only by transporting the granules, or if the installation condition of the conditioned air discharge location is poor, the problem can be solved by using the thermal coupling means with the fan coil unit using the granule receiver as a heat source. A solution can be measured. By circulating the ice melting water in combination with an ice making machine, it becomes possible to obtain a simple cooler for inhaling air in remote areas with good thermal efficiency.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of an airflow granular material conveying apparatus according to the present invention will be described with reference to FIG. Below the bunker 1 is a granule supply path 2, between which there is a gate 3 that can be opened and closed. Granule supply path 2
Is connected to a granule transport path 4 whose periphery is sealed, and a granule receiver 5 is disposed at the end. From the middle of the transport path 4,
Pipes 6 are arranged at predetermined intervals and connected to a high-pressure air tank 8 via a valve 7. The high-pressure air tank 8 can be supplied with compressed air through a pipe 10 by a compressor 9. The high pressure air tank 8 has a valve 11
A pipe 12 extending to the vicinity of the downstream side of the gate 3 via is further provided.

The granules 13 filled in the bunker 1 are moved to the granule supply path 2 with the gate 3 opened, and the gate 3 is closed again and hermetically closed. When the valve 11 is opened, the pipe 12
Then, the high-pressure air flows in, and the particles form a piston flow, move in the particle transport path 4 and reach the particle receiver 5. Even in a normal operation state, the valves 7 are individually controlled to assist the smooth movement of the granules 13. When the mixing ratio of the mass flow rate of the granular material to the flow rate of the air is set to 0.1 or more, the transfer power can be reduced. However, the granules 13 may be clogged. In such a case, the upstream side is sequentially used from the side closer to the outlet side, or sequentially from the downstream side closed place when the closed place is known by using the closed place detector. The valve 7 is opened and closed to the side to move the occluding fluid to the particle receiver 5. It is also possible to use a tank of nitrogen gas, carbon dioxide gas, helium gas, etc. instead of the high-pressure air tank 8, but an air tank is optimal from an economical point of view. It is also possible to store high-pressure air by the compressor 9 by effectively utilizing the above.

FIG. 2 shows a second embodiment of the airflow granular material transport device. The role of the conveying air path of the valve 11 and the pipe 12 in the first embodiment shown in FIG. The pipe 17 extends to the vicinity of the downstream side of the openable and closable gate 3 attached to the upper part of the bunker 1. When the gate 3 is closed, the bunker 1 is kept airtight. If the granules 13 do not sufficiently reach the granule transport path 4 by natural fall (possibly such a situation always occurs), the valve 16 is opened. The granules 13 in the bunker 1 are driven out to the granule transport path 4. The method of operating the valve 7 to assist the smooth movement of the granules 13 and release the blockage of the granules is the same as in the first embodiment. The feature of the second embodiment is that the high-pressure air tank 8 is different from that of the first embodiment.
Capacity can be greatly reduced. FIG. 2 includes a conditioned air generation portion, which will be described later.

FIG. 3 shows a third embodiment of the airflow granular material transport device. A nozzle 18 is provided instead of the valve 16, the pipe 17, and the gate 3 in the second embodiment shown in FIG.
The nozzle 18 is arranged near the entrance of the granule transport path 4 in the enlarged grain supply path 2. When the air from the fan 14 is blown out from the nozzle 18, the pressure near the outlet of the granule supply path 2 becomes negative, and the granules 13 are smoothly supplied from the bunker 1. The method of operating the valve 7 to assist the smooth movement of the granules 13 and release the blockage of the granules is the same as in the first and second embodiments. The capacity of the high-pressure air tank 8 is substantially the same as that of the second embodiment, and the operation is simplified because the operation of the gate 3 and the valve 16 is not required. FIG. 3 also includes a conditioned air generation part, which will be described later.

Next, an air conditioner including the above-described airflow granular material transfer device will be described. For convenience of illustration, the drawing shows a combination of the second embodiment of the airflow granular material transport device and the conditioned air generation system using the transport air as conditioned air, and the third embodiment of the airflow granular material transport device and transport. It is shown in combination with a conditioned air generation system that is thermally coupled to a fan coil unit using the heat storage granules as a heat source.
Any of the methods can combine the two methods of conditioned air generation. Therefore, description of the airflow granular material transfer device will be omitted unless it has a special relation to conditioned air generation.

A first embodiment of the system for directly using carrier air will be described with reference to FIG. In FIG. 2, the granules 13 are heat storage granules, the bottom surface of the granule receiver 5 is a lattice member 20,
The side surface has a closed structure except for the carrier air flow control hole. If the heat storage particles 13 are high-temperature heat storage particles such as high-temperature latent heat storage capsules, high-temperature sensible heat particles, boiler combustion residue residue processed particles, the particles are heated in the particle transport path 4 and the particle receiver 5. The heated conditioned air 21 is discharged. If the heat storage particles 13 are cold heat storage particles, for example, ice, the conditioned air for cooling 21 will be obtained. FIG. 2 shows a case in which the ice particles 13 are used. In this case, the ice melt is returned to facilitate circulation use. The ice melting water 22 is received by the ice melting water receiving pan 23 and the pump 24
The water is returned to the ice making machine 27 through the pipe 26 while adjusting the amount of water with the valve 25. The ice particles 13 generated by the ice making machine 27 are supplied to the bunker 1. The purpose of circulating the heat medium (ice 13 and ice melt 22) is to improve the thermal efficiency.
Of course, circulation system (pump 24, valve 25, pipe 26)
It can be operated as an open system without any. This circulation system can be applied to all air conditioners using ice particles.

FIG. 4 shows a second embodiment of a method for directly using carrier air.
Shown in The conditioned air 21 is discharged from the upper surface of the granule receiver 5 through the vent hole 28, and a storage space for the heat storage granules 13 is provided below. A porous cloth or a wire mesh may be used on the upper surface of the particle receiver 5. The heat storage particles 13 may of course be high-temperature heat storage particles or cold heat storage particles, but in the illustrated case, a drain pipe 29 and a drain cock 30 are provided as ice particles. In this embodiment, a part of the granule transport path 4 may be used as the granule receiver 5.

FIG. 5 shows a third embodiment of a method for directly using carrier air.
Shown in The granule receiver 5 is made of a foldable material such as vinyl, aluminum foil, flexible cloth, etc., and is used as a body of a granule conveying path extending means having a storage space for the heat storage granules 13 in a stretched state during use. Eggplant The carrier air, that is, the conditioned air 21 that has received the heat transfer at its tip is discharged. If a heat-resistant foldable material is used, it can be used for heating, but is suitable for simple cooling in terms of the foldable material. In this embodiment, the particle receiver 5 may be lengthened and used as the particle transport path 4.

FIGS. 6 and 7 show a fourth embodiment of a method for directly using carrier air. In the structure of the present embodiment, the fan 31 is installed by opening the upper part of the granule receiver 5 in the first embodiment using the direct use of carrier air. Thereby, the lower lattice member 20 and the conditioned air 21 discharged from the granular material transport path 4 are formed.
The conditioned air 21 generated by receiving heat transfer from the heat storage granules 13 sucked through and accumulating in the granule receiver 5 is forcibly exhausted from above. In order to improve the ventilation from the lower surface of the granule receiver 5, as shown in FIG. 7, a ventilation duct 32 is used to prevent infiltration of the heat storage granules 13 by using a lattice-like member and to facilitate the passage of air sucked from outside air. It may be provided. The cross-sectional shape of the ventilation duct can be cylindrical, box-shaped, or the like depending on the required ventilation resistance.
The state of the moon can vary. The heat storage granules 13 can be applied to both high temperature and cold heat. A first embodiment of a thermal coupling system with a fan coil unit will be described with reference to FIG. In FIG. 3, water 40 stored in a granule receiver 5 is heated or cooled by a heat storage granule, and is circulated by a pump 41 through a pipe 42, a heat exchanger 44 of a fan coil unit 43, and a pipe 45. This allows the fan coil unit 4
At 3, conditioned air 21 for heating or cooling is generated.

A second embodiment of the present invention will be described with reference to FIGS. 8 and 9. FIG. These figures show the case of the cold heat storage particles 13. Granule receptor 5
Thermal coupling means 46 between the fan coil unit 43 and
A circulating thermosyphon with an evaporating liquid such as alcohol or chlorofluorocarbon is sealed inside. The condenser part 47 is buried in the cold heat storage granules 13, whereby the sealing medium is liquefied and sent to the evaporator part 49 through the liquid return pipe 48. The outside air sucked by the fan 50 of the fan coil unit 43 evaporates the enclosed medium and cools down.
I will provide a. The sealing medium vaporized in the evaporator section 47 is circulated to the condenser section 47 through the vapor transfer pipe 51. When the high-temperature heat storage granules 13 are used, the portion indicated by reference numeral 47 in the granule receiver 5 is an evaporator portion, the portion indicated by reference numeral 49 in the fan coil unit 43 is a condenser portion, and the action portion is Since the position of the condenser unit 49, that is, the position of the fan coil unit is higher, the position of the evaporator unit 47,
That is, it is necessary to change the relative position so that the position of the granule receiver 5 is lower.

FIG. 9 shows a configuration in which a heat flow control device is added in the middle of the liquid return pipe 48 of the thermal coupling means 46 shown in FIG. It comprises a tank 52 for storing a sealed liquid, a U-shaped tube 53 arranged in an inverted U-shape for switching the return liquid flow, and a heater 54 arranged at the inlet end of the U-shaped tube 53 and serving as a control terminal. When the heater 54 is operated and heated, air bubbles are generated at the entrance of the U-shaped tube 53 (at the position of the heater 54), and the filled liquid is pumped up by the pumping action. When the heating of the heater is stopped, no air bubbles are generated and the liquid flow is stopped. In this case, it is also possible to use the high-temperature heat storage particles, but in addition to the above-described replacement of the working part and the relative height of the condenser part and the heat storage part, the configuration of the heat flow control device accompanying the change in the direction of the filled liquid flow. It is necessary to reverse the parts arrangement.

Third Embodiment A method of thermally coupling with a fan coil unit A third embodiment will be described with reference to FIG. The illustration also shows the case of the cold heat storage particles 13. As the thermal coupling means 46 between the granular container 5 and the fan coil unit 43, a heat pipe filled with an evaporable liquid is used. The principle of operation is the same as that of the second embodiment of the thermal coupling method with the fan coil unit. However, in the second embodiment, the portion constituted by two pipes is replaced by one thick pipe in this embodiment. The only difference is that both the gas and liquid phases automatically use the flow path. When the high temperature heat storage particles 13 are used, the replacement of the working part of the condenser part and the evaporator part and the replacement of the relative height are the same as in the second embodiment. However, it is impossible to use a heat flow control device as shown in FIG.
