DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat storage air conditioning system for a building.

[0002]

2. Description of the Related Art As one of air conditioning systems for buildings, a low-cost nighttime electric power is used to operate a heat source device such as a refrigerator to store cold or hot heat in a heat storage tank, and to store the stored heat in the daytime. Conventionally, a thermal storage air-conditioning system for reducing daytime peak load by using the air-conditioning operation of the air conditioner has been used.

FIG. 35 is an explanatory diagram conceptually showing an example of such a conventional thermal storage air conditioning system. In this air conditioning system, for example, during the night of the cooling period, the cooling heat generated by the heat source unit a installed on the rooftop is generated. By cooling the water in the heat storage tank b installed underground, and storing cold heat as cold water or ice in the heat storage tank b, and during daytime cooling,
Cooling air (air conditioning air) is generated by the air conditioner c using the cold heat of cold water or ice in the heat storage tank b, and this is blown out from the outlet d in each room to perform cooling.

On the other hand, as another prior art, an air conditioning system has been proposed in which a heat storage space formed in a building frame is used for heat storage in air conditioning. In the conventional technology, in a heating operation, a configuration in which a warm air from an air conditioner is switched between an indoor heating state in which the air is supplied to a room and a frame heat storage state in which the warm air is supplied into a closed space between a floor slab and a ceiling plate, is used as a heating state. The room temperature is quickly raised to the set temperature at the beginning of the process.
(See Japanese Patent No. 2524817)

[0005]

The former thermal storage air-conditioning system requires large-scale facilities for producing and storing cold (warm) water or ice as a thermal storage medium, so that the initial cost is increased. In addition, there is a problem that a space for installing these facilities is required, and an influence of a weight of the apparatus on a structure of a building is caused. on the other hand,
In the latter air-conditioning system, the path for supplying hot air into the closed space between the floor slab and the ceiling panel in the building heat storage state and the path for supplying warm air to the room in the indoor heating state are exclusively used. It is not envisaged that the heat stored in the frame constituting the closed space is recovered and effectively used in the indoor heating state. In other words, in this prior art, even though it is said that heat is stored in the skeleton, this heat storage preheats the skeleton that affects the rise in room temperature at the beginning of the heating state. Is not used effectively in the heating state. The present invention has been devised to solve such a conventional problem, that is, in building air conditioning, heat is stored without requiring large-scale facilities, and this stored heat is used during air conditioning operation. It is an object of the present invention to provide a heat storage air conditioning system that can be used effectively.

[0006]

In order to solve the above-mentioned problems, according to the present invention, a closed space formed by a structure of a building is formed as an air passage, and at the same time, the air conditioner is switched from the air conditioner to the air conditioner through the air conditioner space. The air passage of the closed space is arranged at an appropriate position of the circulating air passage, and heat is stored in the structure by flowing the entire amount of conditioned air flowing through the conditioned air passage through the air passage of the closed space during operation outside the air conditioning time. In the operation within the air conditioning time, the air
We propose a thermal storage air-conditioning system that collects heat storage by flowing the entire amount of air-conditioning air flowing through the path and uses it for air conditioning.

According to the present invention, in the above configuration, the temperature of the conditioned air flowing through the conditioned air path during the operation outside the air conditioning time is smaller than the temperature of the conditioned air flowing through the conditioned air path during the operation during the air conditioning time. Then, it is proposed to set even lower during heating period and higher.

According to the present invention, in the above configuration, the air-conditioned air path during operation outside the air-conditioning time and during the operation during the air-conditioning time can be common, and the air-conditioned air path during the operation outside the air-conditioning time can be a heat storage bypassing the air-conditioned space. It can also be configured as a conditioned air path.

According to the present invention, in the above configuration, in the air-conditioned air path during the operation within the air-conditioning time, the air passage of the closed space can be arranged upstream of the air-conditioned space, It can be located downstream, or it can be located both upstream and downstream of the conditioned space.

Further, in the present invention, in the above-mentioned structure, the closed space can use an appropriate hollow portion formed in an appropriate place such as a floor portion, a column portion, a beam portion, a foundation portion, etc. A space such as a room or an elevator shaft can be used as a closed space.

Further, the present invention proposes that in the above-described configuration, adjacent closed spaces are connected to each other through a communication port to form a series or parallel air passage.

In the present invention, it is proposed that the closed space is divided by the partition plate to form a serial air passage in the closed space.

In the above invention, the closed space formed by the structure of the building is configured as an air passage,
Empty during operation outside of air conditioning hours and during air conditioning hours
Since the entire amount of conditioned air flowing through the air conditioning path is configured to flow , the heat that has been efficiently stored in the structure that forms the enclosed space by the conditioned air that has flowed during operation outside of the air conditioning time is used for the next air conditioning. It can be efficiently collected and effectively used by the conditioned air flowing into the closed space during operation within the time.

In order to perform such heat storage and heat recovery, the temperature of the conditioned air flowing through the conditioned air path during the operation outside the air conditioning time depends on the temperature of the conditioned air flowing through the conditioned air path during the operation during the air conditioning time. On the other hand, it is effective to set lower in the cooling period and higher in the heating period.

If the air-conditioning air path during the operation outside the air-conditioning time is configured as a heat-storage air-conditioning air path that bypasses the air-conditioning space, heat loss from the air-conditioning space is reduced, and the structure constituting the closed space is efficiently provided. Heat storage can be performed.

When an air passage in a closed space is arranged on the upstream side of the air-conditioned space in the air-conditioned air passage during the operation within the air-conditioning time, the conditioned air from the air conditioner recovers heat stored in the air passage in the closed space. After the air conditioner is supplied to the air-conditioned space, conditioned air at a predetermined temperature can be supplied to the air-conditioned space immediately after the air conditioner is started.

In the case where an air passage of a closed space is arranged downstream of the air-conditioned space in the air-conditioned air path during the operation within the air-conditioning time, the air-conditioned air from the air-conditioner is air-conditioned in the air-conditioned space. Since the heat storage is recovered in the air passage of the closed space, the stored heat can be radiated until the temperature becomes approximately equal to the temperature of the air-conditioned space, and efficient heat recovery is performed.

By connecting adjacent closed spaces through communication ports to form a serial or parallel air passage, or by partitioning the closed space by a partition plate to form a serial air passage in the closed space, air The degree of freedom in design can be increased, for example, the air inflow portion and the air outflow portion of the passage can be formed on one side of the closed space, and the length of the ventilation passage can be appropriately adjusted.

[0019]

Next, an embodiment of the present invention will be described with reference to the drawings. 1 to 6 are system diagrams conceptually showing a configuration of a heat storage air conditioning system of the present invention. In these drawings, reference numeral 1 denotes an air conditioner, 2 denotes an air-conditioned space such as a room, and 3 denotes a structure of a building. The closed space 3 is formed by a body 4, and the closed space 3 is provided with an appropriate air inflow portion 5 and an air outflow portion 6 in appropriate places to form an air passage 7. The air passage 7 is disposed at an appropriate position of an air-conditioned air path that returns from the air conditioner 1 to the air conditioner 1 through the air-conditioned space 2 to form an air-conditioned air path A in the present invention. The air inlet 5 and the air outlet 6 in the air passage 7 are distinguished for convenience, each of which operates as an air inlet in one operating state and at another time as an air outlet. It also includes a configuration that performs the following.

FIG. 1 shows a first embodiment. In this embodiment, the discharge side 8 of the air conditioner 1 and the air inlet 5 of the air passage 7 and the air outlet 6 and the air conditioned space 2 An air pipe is connected between each of the air inflow side 10, the air outflow side 11 of the air conditioning space 2, and the suction side 9 of the air conditioner 1.
Accordingly, in this embodiment, the air conditioner 1 is connected to the air passage 7.
And an air-conditioned air path that returns from the air-conditioned space 2 to the air conditioner 1 through the air-conditioning space 2.

In this configuration, the air-conditioned air circulates through the same air-conditioned air path, as indicated by solid and broken arrows, both in the operation outside the air-conditioning time and in the operation during the air-conditioning time. That is, in the operation outside the air conditioning time, the entire amount of the conditioned air supplied from the discharge side 1
Flows into the air passage 7, flows through the air passage 7,
It flows out of the air outflow part 11 and reaches the air-conditioned space 2. The conditioned air that has reached the air-conditioned space 2 from the air inflow side 10 blows out from the air outlet in the air-conditioned space, then flows out from the air outflow side 11 and returns to the suction side 9 of the air conditioner 1. In this operation, when the conditioned air flows through the air passage 7, heat is applied to the structure 4 of the building constituting the closed space 3 as the air passage 7 to store heat. In the operation of the air conditioning time, the air-conditioning air supplied from the discharge side 1, the total amount
There was flowed from the air inlet section 5 to the air passage 7, the air passage 7 to flow, the air-conditioned space 2 flows out from the air outlet portion 11
Leads to. The conditioned air that has reached the air-conditioned space 2 from the air inlet side 10 blows out from an air outlet in the air-conditioned space 2,
After being supplied to the room for air conditioning, the air is sucked from the air suction port in the air-conditioned space 2 and then flows out from the air outflow side 11 and returns to the suction side 9 of the air conditioner 1. In this operation, when the conditioned air flows through the air passage 7, the structure 4 of the building constituting the closed space 3 as the air passage 7, contrary to the above,
, And the heat is carried to the air-conditioned space 2 for air conditioning. In order to efficiently perform such heat storage and heat recovery, for example, in the cooling period, the temperature of the conditioned air supplied from the discharge side 8 of the air conditioner 1 during the operation within the air conditioning time is set to 18
When the temperature is set to about ° C., outside the air conditioning time, the operation is performed by setting the temperature of the conditioned air to a temperature lower than the above temperature, for example, about 12 ° C. In the heating period, if the temperature of the conditioned air supplied from the discharge side 8 of the air conditioner 1 during operation within the air conditioning time is set to about 18 ° C., outside the air conditioning time, the temperature of the conditioned air is higher than the above temperature, for example, It is effective to operate with the temperature set to about ° C. However, in the first embodiment, since the air passage 7 of the closed space 3 is disposed upstream of the air-conditioned space 2 in the air-conditioned air path A, the air-conditioner 1 When the conditioned air has not reached the predetermined air conditioning temperature, or when the conditioned air from the air conditioner 1 receives heat absorption (cooling period) or heat radiation (heating period) on the path leading to the air passage 7 and deviates from the air conditioning temperature. In this case, there is an effect that the air-conditioning temperature can be brought about by the heat exchange in the air passage 7, so that the same air-conditioning temperature can be set both outside the air-conditioning time and within the air-conditioning time in some cases.

Next, FIG. 2 shows a second embodiment of the present invention. The second embodiment is substantially the same as the first embodiment, except that a bypass path 13 that bypasses the conditioned space 2 is provided in the conditioned air path A. Therefore, the same components as those in FIG. 1 are denoted by the same reference numerals, and redundant description will be omitted. Symbols 12a and 12b
Schematically shows a path switching means, but these path switching means 12a and 12b can be constituted by an appropriate element such as a damper capable of switching a path. In this embodiment, the operation is performed by operating the path switching means 12a and 12b so that the conditioned air flows through the bypass path 13 outside the air conditioning time. In this operating state, the entire amount of the conditioned air supplied from the discharge side 1 of the air conditioner 1 flows into the air passage 7 from the air inflow section 5 as shown by the solid line in the drawing. It flows and flows out of the air outflow portion 6. Next, the conditioned air flowing out of the air outlet 6 does not go to the air-conditioned space 2 as shown in FIG.
To return to the suction side 9 of the air conditioner 1. As described above, in this operation, when the conditioned air flows through the air passage 7, heat is applied to the structure 4 of the building constituting the closed space 3 as the air passage 7 to store heat. In the operation outside the air conditioning time in this embodiment, the conditioned air is supplied to the conditioned space 2.
As a result, there is no heat radiation loss in the air-conditioned space 2, so that efficient heat storage can be performed in the structure constituting the closed space. On the other hand, during operation within the air conditioning time, the conditioned air flowing out of the air outflow section 6 returns to the air conditioner 1 through the air conditioning space 2 as shown in FIG. 1, that is, the same air conditioning as in the first embodiment. It is provided for air conditioning via the air path.

Next, FIG. 3 shows a third embodiment of the present invention. The third embodiment is the same as the first embodiment except that the air passage 7 of the closed space 3 is disposed downstream of the air-conditioned space 2 in the air-conditioned air path. Are given the same reference numerals, and redundant description is omitted. That is, in this embodiment, the first
In the same manner as in the first embodiment, in both the operation outside the air-conditioning time and the operation within the air-conditioning time, the conditioned air circulates through the same conditioned air path as indicated by solid lines and broken arrows, respectively. In the case of this embodiment, the conditioned air from the air conditioner 1 is air-conditioned in the air-conditioned space 2,
Since the heat storage is recovered in the air passage 7 of the closed space 3, the stored heat can be radiated until the temperature becomes equal to the temperature of the air-conditioned space, and efficient heat recovery is performed.
Since the heat is returned to the air conditioner 1 in a state where the heat storage is recovered, the heat load of the air conditioner 1, that is, the coil load can be reduced. Therefore, the air conditioner 1 can cope with the heat load immediately after the start. So that peak cut and low-cost operation can be performed.

Next, FIG. 4 shows a fourth embodiment of the present invention. The fourth embodiment is substantially the same as the third embodiment, except that a bypass path 13 for bypassing the air-conditioned space 2 is provided in the air-conditioned air path A. Therefore, similarly to the above, the same components as those in FIG. 3 are denoted by the same reference numerals, and redundant description will be omitted. In this embodiment, similarly to the second embodiment, in the operation outside the air-conditioning time, the conditioned air does not pass through the air-conditioned space 2, so that there is no heat dissipation loss in the air-conditioned space 2, thus forming a closed space. Efficient heat storage can be performed on the structure.

Next, FIG. 5 shows a fifth embodiment of the present invention. The fifth embodiment is a combination of the first and third embodiments, so to speak, the air-conditioned air path A
, The air passage 7 of the closed space 3 is arranged on both the downstream side and the upstream side of the air-conditioned space 2. In this figure, the same components as those described above are denoted by the same reference numerals, and redundant description will be omitted. In this embodiment, both operations of the above-described first embodiment and second embodiment can be realized during the operation within the air conditioning time.

Next, FIG. 6 shows a sixth embodiment of the present invention. This sixth embodiment is a combination of the fifth embodiment and the second or fourth embodiment.

In this figure, the same components as those described above are denoted by the same reference numerals, and redundant description will be omitted. In this embodiment, in addition to the operation of the fifth embodiment, as described above, it is possible to efficiently store heat in the structure constituting the closed space during operation outside the air conditioning time. The operations of the second embodiment and the second embodiment can be realized.

The configuration of the air piping system for configuring the conditioned air path A in each embodiment of the present invention described above is appropriate.

Next, a specific example of the closed space 3 constituted by the building structure 4 to be operated as a heat storage unit in the present invention will be described. 7 to 14 show specific examples in which a closed space formed on the floor of a building is used as an air passage operated as a heat storage unit.

In each of the above-described configurations, by providing the series air passages 7 as described above, the air inflow portion 5 and the air outflow portion 6 can be configured on one side of the closed space 3 as illustrated. Thus, the configuration of the piping system connected to these can be rationalized. In addition, since such a series of air passages 7 increases the distance of the air passages 7, the distance of heat exchange between the conditioned air and the structure 4 constituting the air passages 7 can be increased. For this reason, the degree of freedom in design such as the configuration of the piping system and the setting of the heat exchange distance is increased. The closed space 3 which forms the air passage 7 in series in this manner can be formed in any of the above-described portions, in addition to the floor portion in this example.

As described above, according to the present invention, the heat stored during the operation outside the air-conditioning period is effectively used during the operation during the air-conditioning period. a. Daytime peak loads can be reduced. b. By storing heat using cheap nighttime power, running costs can be reduced. c. When applied to the floor air-conditioning system, since there is no heat loss in the floor frame portion, a comfortable indoor environment can be provided from the beginning. d. Without the need for special equipment such as cold water heat storage equipment and ice heat storage equipment, heat can be stored using electric power at night, and this can be used during air-conditioning operation, which can reduce equipment construction costs. . e. Further, the space for installing the special equipment as described above is not required, and the structural reinforcement of the building by the weight of the equipment is unnecessary. f. High heat storage efficiency due to low heat loss. g. Since the above heat storage and its use are performed using cold air and hot air, conventional air conditioning equipment can be used. h. For example, when a concrete panel with supporting columns is mounted on a floor slab, and a closed space is constructed by attaching a plate made of a material with high specific heat or a material with high heat insulation to the structure, heat storage is unnecessary. It can be easily removed when it becomes necessary. It can also be installed easily when introducing a thermal storage air conditioning system into existing buildings.
