Description

[0001]
BACKGROUND OF THE INVENTION
In the present invention, an air conditioner is disposed in a ceiling space formed between the ceiling of the floor and the upper floor slab in the multilayer floor building, and the ceiling space is air-conditioned in the late-night power hours so that the multilayer floor More particularly, the present invention relates to a housing heat storage air conditioning system using a so-called cassette type air conditioner.
[0002]
[Prior art]
Conventionally, as this type of housing heat storage air conditioning system, for example, one disclosed in Japanese Patent Publication No. 50-20382 has been known.
FIG. 12 shows a conventional system according to the housing heat storage air conditioning system disclosed above.
In the frame heat storage air conditioning system 1a shown in the figure, a ceiling-embedded air conditioner is installed in a ceiling space 53 formed between the ceiling 51C of the floor 51 and the upper floor slab 52A in the multi-story building 50. 54 is arranged.
An air duct 56 communicating with an air outlet 57 provided on the ceiling 51 </ b> C and a ventilation path switching unit 55 are connected to the outlet side of the air conditioner 54. The ventilation path switching unit 55 switches the ventilation path of the conditioned air blown from the air conditioner 54 to the room or the ceiling space 53 of the floor 51. An air suction port 58 is provided in the ceiling 51C.
[0003]
In this enclosure heat storage air conditioning system 1a, during normal air conditioning operation (for example, daytime cooling operation), the indoor air of the floor 51 flows into the ceiling space 53 from the air suction port 58 and is sucked into the air conditioner 54. The refrigerant is sucked on the side, condensed and decompressed by an outdoor unit (not shown), cooled by the refrigerant guided to the air conditioner 54, and then returned to the floor 51 through the air duct 56 and the air outlet 57 to cool the room. .
On the other hand, in the late-night power hours from 22:00 to 8:00 the next morning, the ventilation path of the ventilation path switching unit 55 is switched, so that the air in the ceiling space 53 is sucked and cooled, and then the ceiling space 53 Thus, cold energy is stored in the frame of the multi-story building 50 (mainly, the upper floor slab 52A).
[0004]
Such a housing heat storage air conditioning system 1a is known as being capable of using inexpensive late-night power and leveling day-and-night power consumption. Moreover, since a hot water heat storage unit and an ice heat storage unit are unnecessary, it attracts attention as a system with low initial cost and running cost.
Moreover, since heat is stored in the housing closest to the user of the upper floor 52, heat dissipation loss can be minimized. For example, when the heat is stored in the upper floor slab 52A in winter, it is as if floor heating is performed, so that the user of the upper floor 52 can comfortably not need daytime air conditioning due to heat radiation from the upper floor slab 52A. There are times when you can spend.
[0005]
[Problems to be solved by the invention]
However, in the case of the conventional enclosure heat storage air conditioning system 1a using the air conditioner 54 embedded in the ceiling, the air outlet 57 and the air inlet 58 must be provided in the ceiling 51B. The air duct 56 which connects with the blowing side of the air conditioner 54 and its installation work are also required.
[0006]
In addition, the cool / warm air blown from the ventilation path switching unit 55 of the air conditioner 54 flows not only into the ceiling space 53 but also through the air inlet 58 into the room of the floor 51. Therefore, there is an inconvenience that a room without a person in the middle of the night is unnecessarily air-conditioned and the energy loss increases.
[0007]
In addition, there is a structure that has a ventilation path for outside air on the suction side of the air conditioner for introducing outside air, but the outside air ventilation path is not closed during the heat storage operation, and the outside air at night is a space behind the ceiling. May cause condensation in the ceiling space.
[0008]
The present invention has been made in view of the above-described conventional problems, and has a simple and inexpensive configuration. The object of the present invention is to provide a housing heat storage air-conditioning system with good installation work and other workability and good heat storage efficiency. And

[0013]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
Embodiment 1 of the Invention
FIG. 1 is a schematic configuration diagram showing an overall structure of a housing heat storage air conditioning system according to an embodiment of the present invention, FIG. 2 is an external view of the housing heat storage air conditioning system viewed obliquely from below, and FIG. FIG. 4 is an explanatory view of the inside of the housing heat storage air conditioning system as viewed from the front. However, the same reference numerals are given to the same components as those of the multi-storey building 50 shown in FIG. 12 and the conventional frame heat storage air conditioning system 1a, and detailed description thereof will be omitted.
As shown in FIG. 1, the frame heat storage air-conditioning system 1 according to the first embodiment includes a ceiling space 53 formed between the ceiling 51B of the floor 51 and the upper floor slab 52A in the multi-story building 50. In particular, it has a cassette type air conditioner 2. The cassette type air conditioner 2 is inserted and fixed in a panel mounting hole 4 provided in the ceiling 51B.
[0014]
As shown in FIGS. 2 to 4, the cassette type air conditioner 2 has an air inlet 8 and an air outlet 9 formed in the decorative panel 3 attached to the lower surface of the main casing 7. In addition, a main ventilation path 10 is formed in the main body casing 7 of the cassette type air conditioner 2 so as to communicate the air suction port 8 and the air outlet 9, and the main ventilation path 10 includes a refrigerant circuit. Indoor side heat exchangers 13 and 13 constituting a part and a blower fan 12 accommodated in the fan casing 11 are provided.
In this cassette type air conditioner 2, the suction side main ventilation path 14 of the main ventilation path 10 on the upstream side of the blower fan 12 is branched and connected to the suction side auxiliary ventilation path 16 communicating with the ceiling space 53. Yes. A filter 29 is interposed in the vicinity of the air inlet 8 of the suction side main ventilation path 14. In addition, a blowout side secondary ventilation path 18 that communicates with the ceiling space 53 is branched and connected to the blowout main ventilation path 15 of the main ventilation path 10 on the downstream side of the blower fan 12.
[0015]
A suction-side switching damper 23 that opens and closes the suction-side auxiliary ventilation path 16 is provided at the branch connection position of the suction-side auxiliary ventilation path 16. The suction side main ventilation path 14 is not closed by the suction side switching damper 23 and is always open. However, the outlet side of the cassette type air conditioner 2 has a positive pressure and the suction side has a negative pressure. The pressure balance in the back space 53 is balanced, and the conditioned air circulates well. Therefore, room air is not sucked from the air suction port 8 and the suction side main ventilation path 14.
Further, at the branch connection position of the outlet side auxiliary ventilation path 18, an outlet side switching damper 28 for switching the ventilation path to either the outlet side main ventilation path 15 or the outlet side auxiliary ventilation path 18 is provided.
[0016]
Then, operation | movement of the housing heat storage air conditioning system 1 is demonstrated.
First, in a normal air-conditioning operation performed during the daytime, for example, a cooling operation, as shown in FIGS. 4 to 7, the suction-side switching damper 23 and the outlet-side switching damper 28 are switched so that the suction port 24 in the ceiling and the branch outlet are switched. The outlet 20 is closed, and both the suction side auxiliary ventilation path 16 and the outlet side auxiliary ventilation path 18 are closed. As a result, the main ventilation path 10, the suction side main ventilation path 14, and the blowout side main ventilation path 15 communicate with the room air through the air suction port 8 and the air outlet 9.
Therefore, the low-temperature and low-pressure refrigerant condensed by heat exchange with the outside air in the outdoor unit (not shown) and then decompressed by the expansion device flows into the indoor heat exchanger 13 of the cassette type air conditioner 2 to cool the indoor air. Then, it evaporates and is returned to the outdoor unit.
In the heating operation, the refrigerant flow direction of the refrigerant circuit is switched to the opposite direction to that in the cooling operation by the four-way switching valve of the outdoor unit, so that the high-temperature and high-pressure refrigerant flows into the indoor heat exchanger 13 and the room air Is heated and condensed and returned to the outdoor unit.
[0017]
On the other hand, during the heat storage operation in the late-night power hours, as shown in FIGS. 5, 6, 8, and 11, the suction side switching damper 23 (two-dot chain line in FIGS. 5 and 6) and the outlet side switching damper 28 are provided. By switching, the suction port 24 in the ceiling and the branch outlet 20 are opened, and both the suction side auxiliary ventilation path 16 and the outlet side auxiliary ventilation path 18 are in communication with the ceiling back space 53. In this state, the cassette type air conditioner 2 is cooled or heated. Thereby, cold heat or warm heat is stored in the upper floor slab 52A and other housings.
[0018]
In this cassette type air conditioner 2, the decorative panel 3 mounted on the lower surface of the main body casing 7 is originally provided with the air inlet 8 and the air outlet 9. There is no need to provide a suction port, and the air duct that connects the ceiling air outlet and the air conditioner and the installation work thereof are also unnecessary. In addition, since the cool and warm air blown out from the cassette type air conditioner 2 circulates in the relatively narrow ceiling space 53 and does not flow into the room of the floor 51, heat is efficiently stored in the upper floor slab 52A and other frames. It can not be used to unnecessarily cool and heat an unattended room. In addition, fan power is reduced.
[0019]
Embodiment 2 of the Invention
Although the second embodiment has substantially the same configuration as the first embodiment, as shown in FIGS. 1 to 3, in particular, the suction-side subcasing 5 that forms the suction-side auxiliary ventilation path 16 and the outside air ventilation path 40. The left and right outlet side sub-casings 6, 6 that form the outlet side auxiliary ventilation path 18 are configured separately from the main body casing 7, respectively.
The suction side sub-casing 5 is attached to the main body casing 7 by covering the branch suction port 31 provided on the front side surface of the main body casing 7. In addition, what was originally provided for the branch inlet 31 as an opening for external air suction is diverted.
The blowout side sub-casings 6 and 6 are attached to the main body casing 7 so as to cover the branch outlets 20 and 20 respectively provided on the left and right side surfaces of the main body casing 7.
Further, a suction side damper motor 35 for switching and driving the suction side switching damper 23 and a blower side damper motors 38 and 38 for switching and driving the discharge side switching damper 28 are respectively provided in the suction side auxiliary casing 5 and the outlet side auxiliary casings 6 and 6. Are deployed together on the front side.
[0020]
Therefore, according to this embodiment, the existing cassette type air conditioner 2 can be diverted to the housing heat storage type simply by retrofitting the suction side subcasing 5 and the blowout side subcasing 6, 6 to the existing main body casing 7. be able to. Further, the suction side damper motor 35 and the blowout side damper motors 38, 38 are arranged on one side (front side) of each of the suction side subcasing 5 and the blowout side subcasing 6, 6, so that the ceiling 51B and the inside of the ceiling Only one inspection port is required for the inspection work.
[0021]
Embodiment 3 of the Invention
The third embodiment has substantially the same configuration as the first and second embodiments. However, as shown in FIGS. 2, 3 and 5 to 8, the outside air ventilation path 40 for taking in outdoor air is a suction side auxiliary ventilation. A branch connection is made to the path 16. The suction side switching damper 23 is arranged so as to switch the ventilation path to either the suction side auxiliary ventilation path 16 or the outside air ventilation path 40.
That is, the suction side auxiliary casing 5 is occupied by the suction side auxiliary ventilation path 16 and the outside air ventilation path 40 by half. A suction port 24 in the ceiling is provided on the front surface of the suction side sub-casing 5 of the suction side sub-ventilation passage 16, and an outside air suction port 25 is provided on the front surface of the suction-side sub casing 5 of the ventilation passage 40 for outside air. Connected to the outside air inlet 25 is an outside air duct 39 that communicates directly with the outside or communicates with a primary processing device (not shown) that feeds air after the outside air is brought close to the air conditioning conditions in the room.
[0022]
The suction side switching damper 23 includes a rotary shaft 32 pivotally supported in the vertical direction in the suction side sub casing 5, and a lid plate portion 21 and a lid plate portion 22 fixed to the rotary shaft 32. The lid plate portion 22 is integrally formed with the lid plate portion 21 at an angle substantially perpendicular to the horizontal direction. The lid plate portion 21 swings around the rotation shaft 32 to open and close the ceiling suction port 24, and the lid plate portion 22 swings around the rotation shaft 32 to open and close the outside air suction port 25.
One end of the suction side switching damper 23 is fixed to the inner wall of the suction side subcasing 5 and the other end thereof is driven to swing by a wire 33 wound around the suction side damper motor 35. In this case, when the suction-side damper motor 35 stops, the wire 33 is pulled back by the contraction force of the coil spring 34 interposed in the middle, and returns to the original position (position where the cover plate portion 21 closes the ceiling inlet 24). The so-called spring return method is employed.
[0023]
According to this embodiment, since the plurality of ventilation paths are opened and closed by one suction side switching damper 23, the structure of the damper unit is simple. Further, during the heat storage operation, the outside air ventilation path 40 can be reliably closed to prevent dew condensation on the frame in the ceiling space 53, particularly the upper floor slab 52A, at night.
[0024]
Embodiment 4 of the Invention
The fourth embodiment has substantially the same configuration as the first to third embodiments, but as shown in FIGS. 4 and 7 to 11, the blowout side auxiliary casing 6 is a blowout side auxiliary ventilation path 18. . On the upper surface of the blowout side subcasing 6, an in-ceiling air outlet 19 that communicates with the ceiling space 53 is provided. In particular, the blowout side switching damper 28 has a guide plate portion 27 fixed to the rotary shaft 17 pivotally supported in the front and rear in the blowout side auxiliary casing 6, and approximately 120 degrees around the horizontal axis with respect to the guide plate portion 27. And a cover plate portion 26 integrally formed in an angled shape in a front view. The cover plate part 26 swings around the rotating shaft 17 to open and close the branch outlet 20.
The cover plate portion 26 swings between the outlet side main ventilation path 15 and the outlet side auxiliary ventilation path 18 to close the outlet side main ventilation path 15 during the heat storage operation, and during the indoor air conditioning operation, the outlet side auxiliary ventilation path 18. Close. Moreover, when the cover plate part 26 closes the blowout side main ventilation path 15, the guide plate part 27 passes the indoor heat exchanger 13 and blows the conditioned air blown into the blowout side main ventilation path 15. It can be guided into the road 18.
[0025]
Further, a guide casing 30 is provided in the blowout side auxiliary ventilation path 18 so as to be bridged from the vicinity of the rotary shaft 17 to the vicinity of the ceiling outlet 19 and to guide the air from the branch outlet 20 to the ceiling outlet 19. .
The blowing side switching damper 28 is driven to swing by rotating the rotating shaft 17 by a wire 36 having one end fixed to the inner wall of the blowing side auxiliary casing 6 and the other end wound around the blowing side damper motor 38. Here again, when the blowout damper motor 38 stops, the wire 36 is pulled back by the contraction force of the coil spring 37 interposed in the middle, and the spring returns to the original position (position where the cover plate portion 26 closes the branch outlet 20). A return method is adopted.
[0026]
Therefore, according to this embodiment, since the plurality of ventilation paths are opened and closed by the single cover plate portion 26, the damper unit can be configured compactly. Further, during the heat storage operation, the guide plate portion 27 can smoothly guide and blow out the conditioned air from the indoor heat exchanger 13 from the blowout side auxiliary ventilation path 18 to the ceiling back space 53.
[0027]
In addition, as a utilization aspect of this housing heat storage air-conditioning system 1, it does not restrict to each form already illustrated, for example, it drive | operates in the time slot | zones other than from 22:00 to 8:00 of the following morning, or it is predetermined from the predetermined start time. Time control such as driving for a time (for example, 3 hours) can also be performed.
Alternatively, a midnight power usage contract is exchanged with an electric power company, and an external timer that can be sealed is provided, and damper switching is controlled by the time measured by this external timer. Can not be performed. That is, it is possible to prevent the user from operating freely during the midnight power hours.
By the way, there are times when it is desirable to continue indoor air conditioning operation even when the scheduled heat storage time comes due to overtime. In such a case, if the indoor air-conditioning operation can be continued, the user of the upper floor 52 incurs an extra air-conditioning burden and becomes unequal in the air-conditioning operation the next day. Therefore, at least a charge corresponding to excess room air conditioning may be imposed on the user of the floor 51, and this may be used for the burden of the user of the upper floor 52.
[0028]
【The invention's effect】
As described above, according to the housing heat storage air-conditioning system according to the present invention, when performing the heat storage operation that leads to the leveling of the amount of power used day and night, both the air suction side and the air outlet side are communicated with the ceiling space. Since the cassette-type air conditioner is operated in this state and heat is stored in the housing, there is no need to provide an air outlet or suction port on the ceiling as in the prior art, and the air that connects the ceiling air outlet and the air conditioner Ducts and their installation work are also unnecessary. Further, the cassette type air conditioner has a small height in the ceiling and low noise compared to a ceiling embedded type air conditioner conventionally used. In addition, since the cool and warm air blown out from the cassette type air conditioner circulates in a relatively narrow ceiling space and does not flow into the room on the floor, it can efficiently store heat in the upper floor slabs and other enclosures. The energy loss can be reduced without wastefully cooling or heating the room. Of course, it is possible to use inexpensive late-night power that is unique to the system, to eliminate the need for hot water heat storage units and ice heat storage units and to have a simple and inexpensive configuration, and to perform comfortable air conditioning operations with little heat loss. It goes without saying that he plays.
[0029]
In addition, since the suction side sub-casing and the blowout side subcasing are configured separately from the main body casing, the existing cassette type air can be obtained simply by retrofitting the suction side subcasing and the blowout side subcasing to the existing main body casing. The harmony machine can be diverted to the housing heat storage type. Also, the suction side damper motor and the blowout side damper motor are arranged together on one side of each of the suction side subcasing and the blowout side subcasing, so only one inspection port is provided on the ceiling and in the ceiling. Will also be easier.
[0030]
And since the ventilation path is switched by one suction side switching damper to either the outside air ventilation path branched and connected to the suction side auxiliary ventilation path or the suction side auxiliary ventilation path, the damper unit The structure is simple. In addition, during the heat storage operation, the outside air ventilation path is reliably closed by the suction side switching damper, so that condensation in the ceiling space at night can be prevented.
[0031]
Furthermore, since the blowing side switching damper is integrally formed by the lid plate portion and the guide plate portion, the damper unit can be configured in a compact manner. In addition, the guide plate portion can smoothly guide the conditioned air that has passed through the indoor heat exchanger during the heat storage operation from the blowout side auxiliary ventilation path to the space behind the ceiling.
