Description

The present invention relates to an air conditioning system and an air conditioning method using hot and cold water piping.

Radiant air conditioning directly transfers energy via far-infrared rays between a radiation source installed on the ceiling and the space to be air-conditioned. Compared to air-based convection air conditioning, radiant air conditioning can achieve both energy savings and comfort, with less unpleasant airflow sensations and less temperature difference between the top and bottom of the room.

In connection with such a radiant air conditioning method, a mounting structure for mounting a pipe through which hot and cold water flows to a ceiling is also being considered (see, for example, Patent Document 1). The mounting structure described in Patent Document 1 includes a planar plate provided below a ceiling slab in a building, and a pipe holder that is attached to the plate and holds a pipe. The plate is attached to the ceiling slab by the attachment structure for fixing the plate, with the opposite side to which the pipe holder is attached facing and separated from the ceiling slab. In addition, there are two types of thermal storage air conditioning systems that utilize heat stored in a building's frame: a system in which hot and cold water pipes are buried within the building frame, and a system in which hot and cold air is blown directly onto the building frame.

JP2019-113297A

However, in the technology described in Patent Document 1, temperature control is performed only by hot and cold water flowing through the pipes, so efficient air conditioning may not be expected.

An air conditioning system that solves the above problems uses a space formed by a framework made of a cement composition as an air-conditioned space. The air conditioning system is provided at a position away from the surface of the body so as to cover at least a part of the surface of the body, and has a first opening facing the body and a second opening facing the air-conditioned space. a chamber formed therein; a pipe that is disposed so as to be in contact with a lower plate of the chamber and through which a temperature-controlled fluid flows; It is controlled by switching between a first driving state in which a first airflow is directed towards the air conditioner, a second drive state in which a second airflow is formed from inside the chamber toward the air-conditioned space through the second opening, and a stop state. Equipped with a fan. With this first driving state, it is possible to expect heat storage in the frame. Furthermore, the second driving state can be expected to complement and promote radiant air conditioning.

According to the present invention, efficient air conditioning can be realized.

An air conditioning system and an air conditioning method will be explained using FIGS. 1 to 5.
As shown in FIG. 1, the air conditioning system 10 adjusts the temperature of a space 11 to be air conditioned. The air conditioning system 10 uses a slab 12 (framework made of cement composition). The slab 12 is composed of a concrete material 13 and a deck plate 14. The concrete material 13 is concrete that is cast using a steel deck plate 14 as a formwork.

(Air conditioning system configuration)
The air conditioning system 10 has a chamber 20. The chamber 20 is suspended from the slab 12 by suspension bolts 21 and is located away from the surface of the deck plate 14. The chambers 20 are arranged in parallel so as to cover at least a portion of the surface of the slab 12. The chamber 20 is arranged at a distance that allows wind from a fan 40 (described later) to reach the deck plate 14. This distance may be determined depending on the air blowing performance of the fan 40, which will be described later, and is, for example, about 10 cm. The size of the chamber 20 is, for example, about 60 cm in width (short side) and about 1.5 to 3 m in length (long side), taking into consideration transportation, installation, etc.

Chamber 20 has a first panel 22 that constitutes a top plate of chamber 20 . First openings 23 facing the slab 12 are provided in the first panel 22 at predetermined intervals (for example, at intervals of several tens of cm).

The chamber 20 has a second panel 24 that is arranged opposite to the first panel 22 and forms a lower plate of the chamber 20 . The second panel 24 is provided with a mesh-like ventilation hole formed by a second opening 25, which is a hole facing the air-conditioned space 11, in all or part of the area. Furthermore, a peripheral wall 27 of the chamber 20 that connects the upper plate and the lower plate of the chamber 20 is integrally formed on the second panel 24 .

A connecting piece 28 that projects inside the chamber 20 is provided at the upper end of the peripheral wall 27 . The connecting piece 28 is connected to the first panel 22 to be connected. The first panel 22 and the connecting piece 28 of the peripheral wall 27 are connected by a hanging bolt 21 with a chamber sealing material 29 interposed therebetween. Thereby, the gap between the first panel 22 and the peripheral wall 27 is sealed. The chamber sealing material 29 suppresses the flow of air through the gap between the first panel 22 and the peripheral wall 27. The chamber sealing material 29 also functions as a spacer that adjusts the distance between the first panel 22 and the second panel 24 depending on its thickness.

The air conditioning system 10 has piping 30 supported by the chamber 20. Piping 30 has a straight section 31 and a connecting section 32 .
The straight portion 31 and the connecting portion 32 are arranged so as to contact the inner lower surface of the chamber 20, that is, the upper surface of the second panel 24, directly or via a heat sink. The straight portion 31 and the connecting portion 32 constitute a contact portion that contacts the chamber 20. The straight portions 31 are arranged in parallel at predetermined intervals in the interior space of the chamber 20 . The straight portions 31 are mutually connected to adjacent pipes 30 via connecting portions 32 on the back side or the front side of the page in FIG. Note that, hereinafter, the direction in which the straight portions 31 are arranged side by side will be referred to as the left-right direction.

A water supply pipe 33 is connected to the pipe 30. The water supply pipe 33 is connected to each of the straight portions 31 located at both ends in the left-right direction. The water supply pipe 33 is drawn out to the external space of the chamber 20 through a draw-out hole 35 formed at the peripheral end of the chamber 20 . The pull-out hole 35 is formed on the outer side in the left-right direction of the area where the straight portion 31 and the connecting portion 32 are provided. The gap between the water supply pipe 33 and the draw-out hole 35 is preferably sealed with a sealing material (not shown) or the like. In the piping 30, the temperature-controlled fluid is supplied through one water supply pipe 33, and the fluid that has passed through the piping 30 is discharged through the other water supply pipe 33. For example, in the case of cooling, the pipe 30 is supplied with cold water of 15 to 20° C. (for example, underground water), which has a relatively low potential as the fluid, through the water supply pipe 33. Note that the temperature of the fluid may be adjusted using a heat pump or the like to such an extent that no condensation occurs on the surface of the pipe 30.

The air conditioning system 10 has a partition material 38 in the internal space of the chamber 20. The partitioning material 38 partitions the internal space of the chamber 20 into an inner region and an outer region. The inner region is a region where the linear portion 31 and the connecting portion 32 are arranged, and is a region where both the first opening 23 and the second opening 25 communicate. The outer region is a region where a part of the water supply pipe 33 is disposed, and is a region with which the extraction hole 35 communicates. A through hole (not shown) through which the water supply pipe 33 passes is formed in the partitioning member 38 . For the partitioning material 38, a heat insulating material such as glass wool or a rubber sealing material can be used, for example.

The air conditioning system 10 has a fan 40. The fan 40 is attached to the chamber 20 so as to be located between the slab 12 and the first panel 22 and to close each of the first openings 23. The fan 40 is detachably attached to the chamber 20 by a detachable mechanism (for example, a clamp, a hook-and-loop fastener, a magnet, etc.). The fan 40 is a thin fan, for example, a DC fan that can be driven according to the USB (Universal Serial Bus) standard (rated voltage: DC5V). Fan 40 is powered by a USB jack through a cable from a cable rack (not shown). The fan 40 is driven to rotate forward or backward depending on the supplied voltage.

The fan 40 blows air upward by normal rotation, thereby forming a first airflow from the inner region of the chamber 20 toward the slab 12 through the first opening 23 . The fan 40 blows air downward by being driven in reverse, thereby forming a second airflow from the inner region of the chamber 20 toward the air-conditioned space 11 through the second opening 25 .

The air conditioning system 10 includes a diffusion member 41. The diffusion member 41 is provided directly below each first opening 23 , that is, so as to correspond to each fan 40 . The diffusion member 41 diffuses air in the inner region of the chamber 20 when the downward air from the fan 40 collides with the diffusion member 41 . The diffusion member 41 is disposed inside the chamber 20, that is, between the second panel 24 and the fan 40. Furthermore, the diffusion member 41 is disposed between the straight portions 31 . The diffusion member 41 is removably attached to the second panel 24 using an attachment/detachment mechanism (for example, a clamp, a hook-and-loop fastener, a magnet, etc.).

The air conditioning system 10 has a sound deadening member 42 corresponding to each fan 40. The sound deadening member 42 is removably attached to the first panel 22 of the chamber 20 using an attachment/detachment mechanism (eg, a clamp, a hook-and-loop fastener, a magnet, etc.). The sound deadening member 42 is disposed between the slab 12 and the first panel 22. The muffling member 42 has a cylindrical shape surrounding the fan 40 at its lower end. The sound deadening member 42 is made of, for example, a sound insulating material or a sound absorbing material. The upper end of the sound deadening member 42 is preferably located closer to the slab 12 than the first panel 22. In this embodiment, the sound deadening member 42 is a glass wool duct.

As shown in FIG. 2, the air conditioning system 10 includes a control device 50 that controls the drive of the fan 40. The control device 50 switches the drive mode of the fan 40 based on various conditions, for example, based on the measured value of the sensor 51 that acquires state information of the air-conditioned space 11. The sensor 51 measures the temperature (room temperature) and the radiation temperature of the slab 12 as state information of the air-conditioned space 11 .

(Hardware configuration of control device 50)
As shown in FIG. 3, the information processing device H10 that constitutes the control device 50 includes a communication device H11, an input device H12, a display device H13, a storage device H14, and a processor H15. Note that this hardware configuration is just an example, and it can also be implemented using other hardware.

The communication device H11 is an interface that establishes a communication path with other devices and executes data transmission and reception, and is, for example, a network interface, a wireless interface, or the like.

The input device H12 is a device that receives input from a user or the like, and is, for example, a mouse, a keyboard, or the like. For example, it accepts the user's temperature setting, declaration of temperature, wind direction of the fan, and necessity of operation. The display device H13 is a display or the like that displays various information. The storage device H14 stores data and various programs for executing various functions of the control device 50. Examples of the storage device H14 include ROM, RAM, hard disk, and the like.

The processor H15 controls each process in the control device 50 using programs and data stored in the storage device H14. Examples of the processor H15 include a CPU, an MPU, and the like. This processor H15 expands a program stored in a ROM or the like into a RAM and executes various processes for each processing.

(About drive mode)
The control device 50 switches the drive mode of the fan 40 between a first mode, a second mode, and a third mode depending on conditions.

As shown in FIG. 4, the first mode is a mode in which the fan 40 is controlled to a first driving state in which a first airflow from the chamber 20 toward the slab 12 is formed. In the first mode, the fan 40 blows the air sucked into the chamber 20 through the first opening 23 onto the slab 12 . Inside the chamber 20, heat exchange is performed between the air flowing in through the second opening 25 and the pipe 30. That is, the first mode is a heat storage mode in which the heat in the air-conditioned space 11 and the heat of the fluid flowing through the pipes 30 are stored in the slab 12. In addition, in FIG. 4, among the arrows shown in the air-conditioned space 11, the arrows located at both ends indicate air flowing into the chamber 20 from the back side of the diffusion member 41.

As shown in FIG. 5, the second mode is a mode in which the fan 40 is controlled to a second driving state in which a second airflow is formed from the chamber 20 toward the air-conditioned space 11. In the second mode, the fan 40 blows the air near the surface of the slab 12 sucked through the sound deadening member 42 into the chamber 20 . The air sucked in at this time exchanges heat with the slab 12. Then, the downward air generated by the fan 40 is diffused into the chamber 20 by the diffusion member 41, so that air flows out from a wide range of the second panel 24 while exchanging heat with the piping 30. That is, the second mode is a heat radiation mode in which the heat stored in the slab 12 and the heat of the fluid flowing through the piping 30 are radiated to the air-conditioned space 11. Note that, in FIG. 5 , among the arrows shown in the air-conditioned space 11 , the arrows located at both ends indicate air flowing into the air-conditioned space 11 from the back side of the diffusion member 41 .

The third mode is a mode in which the fan 40 is controlled to a stopped state. At this time, the air-conditioned space 11 is air-conditioned by radiation using the chamber 20, more specifically, the second panel 24 as a radiation panel. That is, the third mode is a radiation mode in which radiation air conditioning is performed from the chamber 20.

(About an example of switching drive modes)
The control device 50 includes a timer that outputs the current date and time. The control device 50 then drives the fan 40 according to the schedule (normal rotation or reverse rotation) based on the schedule (temporal conditions) recorded in the storage device H14. For example, the first mode time period (nighttime) and the second mode time period (daytime) are recorded in the schedule.

Further, for example, the control device 50 forcibly switches the drive mode of the fan 40 based on the state information detected by the sensor 51. In this case, the control device 50 switches the drive mode of the fan 40 so that the room temperature of the air-conditioned space 11 becomes the target temperature. When the room temperature of the air-conditioned space 11 is higher than the target temperature by exceeding an allowable range and the temperature of the slab 12 is lower than the target temperature, the control device 50 executes the second mode in which downward air is blown. Further, when the room temperature of the air-conditioned space 11 is lower than the target temperature by exceeding the allowable range and the temperature of the concrete material 13 is higher than the target temperature, the control device 50 executes the first mode in which upward air is blown. Furthermore, when the room temperature is stable, the control device 50 executes a third mode in which the fan 40 is stopped.

(effect)
By driving the fan 40, heat in the chamber 20 and the air-conditioned space 11 is processed and stored in the slab 12. Further, the heat stored in the slab 12 is radiated to the air-conditioned space 11 by reverse driving of the fan 40 or by radiation.

According to this embodiment, the following effects can be obtained.
(1) In the air conditioning system 10, the chamber 20 is arranged at a position spaced apart from the slab 12. Thereby, radiant air conditioning of the air-conditioned space 11 can be performed using the slab 12 as a heat storage material. For example, even when the air-conditioning load of the air-conditioned space 11 fluctuates, heat is stored in the slab 12 when the air-conditioning load is small, and heat stored in the slab 12 is radiated when the air-conditioning load is large. This makes it possible to balance the air conditioning load.

Further, by using the chamber 20, heat exchange between the fluid flowing through the piping 30 and the air passing through the chamber 20 can be performed efficiently. As a result, heat can be efficiently stored in the slab 12 and heat can be radiated to the air-conditioned space 11.

(2) Inside the chamber 20, the pipes 30 are arranged in parallel at predetermined intervals and extend in contact with each other directly or via a heat sink. This simplifies construction work, unlike the case where the piping 30 is embedded in a building frame such as a concrete slab.

(3) The fans 40 supported by the chamber 20 are provided at predetermined distances (for example, several tens of cm). Thereby, even when the slab 12 and the chamber 20 are separated, heat storage can be promoted by using the fan 40 to blow air to the slab 12. Further, by using the fan 40 to blow air into the air-conditioned space 11, forced convection air conditioning and heat radiation can be promoted. Furthermore, by using a DC cooling fan that can be driven in accordance with the USB standard, ventilation can be achieved with a general-purpose product that saves power.

Further, the fan 40 is attached to the chamber 20 by a detachable mechanism (for example, a clamp, a hook-and-loop fastener, a magnet, etc.). This makes it easy to change the arrangement and maintain the fan 40.

Further, by providing the piping 30 in the chamber 20 and providing the fan 40 on the upper plate of the chamber 20, the degree of freedom of the lower surface on the side of the air-conditioned space 11 can be ensured.
(4) The control device 50 starts and stops the fan 40 according to a schedule. Thereby, even when the heat load in the air-conditioned space 11 changes periodically, the drive mode can be switched using this periodicity. For example, nighttime electricity may be used to cause hot and cold water whose temperature is adjusted by a heat pump to flow through the piping 30 to store heat or cool the slab 12.

Further, a sensor 51 is connected to the control device 50. Then, the control device 50 uses the measurement information from the sensor 51 to forcibly switch the drive mode. Thereby, the drive mode of the fan 40 can be switched depending on the conditions of the air-conditioned space 11 and the slab 12.

(5) A chamber sealing material 29 is provided in the gap between the first panel 22 and the peripheral wall 27. Thereby, air can be prevented from flowing into and out of the chamber 20 through the gap. As a result, of the air that has flowed into the chamber 20, the proportion of air that passes near the piping 30 can be increased.

(6) By making the chamber sealing material 29 function as a spacer, the volume of the chamber 20 can be increased according to the thickness of the chamber sealing material 29 without changing the shapes of the first panel 22 and the second panel 24. can do. As a result, the degree of freedom in designing the pipe 30, such as the pipe diameter and route, can be improved.

(7) A partitioning material 38 is provided within the chamber 20. Thereby, it is possible to suppress the flow of air through the extraction hole 35 and to limit the range of air flow through the second opening 25. This allows more air to pass near the piping 30 within the chamber 20.

(8) The fan 40 is provided between the slab 12 and the chamber 20 so as to face the first opening 23. Thereby, in the first mode, the air inside the chamber 20 can be efficiently sucked. Moreover, in the second automatic mode, air can be efficiently discharged into the chamber 20.

(9) The diffusion member 41 is disposed between the second panel 24 and the slab 12 and diffuses the downward air blown by the fan 40 in the direction along the second panel 24 in the second mode. This allows more air to exchange heat with the piping 30 and the second panel 24.

(10) The diffusion member 41 is disposed between the straight portions 31 arranged in parallel. This makes it possible to increase the proportion of air passing near the piping 30 among the air whose direction has been changed by the diffusion member 41.

(11) The diffusion member 41 is provided to correspond to each fan 40. Thereby, in the second mode, the downward air blown from each fan 40 can be diffused into the chamber 20.

(12) A sound deadening member 42 is arranged around the fan 40. Thereby, noise caused by driving the fan 40 can be suppressed.
(13) The fan 40 is disposed inside the lower end of the cylindrical sound deadening member 42. According to such a configuration, when the fan 40 blows air upward, the accuracy of the direction of the upward air blowing can be improved. Moreover, since the upward air that has reached the slab 12 flows along the slab 12, heat can be efficiently stored in the slab 12.

(14) The fan 40 and the sound deadening member 42 are arranged between the slab 12 and the chamber 20. Thereby, when viewed from the air-conditioned space 11 side, the fan 40 and the muffling member 42 can be covered with the chamber 20.
