Description

  The present invention relates to a chamber box used for a ventilating air conditioning system capable of simultaneously achieving ventilation and air conditioning of a space above a floor of a building while utilizing ground cooling heat.

  In a typical house, the floor space is divided into a plurality of room spaces, and each room space is provided with an air conditioner (air conditioner). Therefore, each room space is individually air-conditioned by each air conditioner. However, such an air conditioning system requires ventilation separately.

  On the other hand, air under heat exchange with the ground side of the underfloor space is stored in the underfloor space of the building. Generally, the temperature of the air heat-exchanged with the ground in the underfloor space is lower than the outside air in summer and higher than the outside air in winter. Therefore, for example, it is not necessary to actively use the air conditioner, but if you want to adjust the temperature a little (early in the summer or winter), use air in the space below the floor to perform ventilation and air conditioning. It can be realized more efficiently. Related technologies include the following.

  The present invention has been made in view of the problems as described above, and is a chamber used for a ventilating air conditioning system that can realize ventilation and air conditioning of the space above the floor of a building using air in the space below the floor. Providing a box is the main issue.

The present invention is a ventilating air conditioning system for a building comprising an underfloor space surrounded by a base, the ground and a floor, and an upper floor space thereabove, comprising: a chamber box; and air in the chamber box. A first space having a first inlet for taking in the air of the underfloor space, and a second space into which the air conditioned by the air conditioner is introduced; and space, and a closing portion communicating or blocking the said second space and the first space, possess an exhaust port provided in the first space, the air conditioner is in said second space The second space is provided with an on-floor air inlet for taking in air in the on-floor space, and the second space is on the floor when the air conditioner is stopped. Taken from the air inlet The air of the floor space, can be supplied to the first space, the air supply device is characterized in that it comprises an air purification device for cleaning the air of the first space is supplied from the exhaust port .

  In another aspect of the present invention, the floor air inlet may be provided at a position offset in the horizontal direction, not immediately above the air conditioner.

  In another aspect of the present invention, the second space is further provided with a shielding portion for preventing mixing of the air in the space above the floor and the air-conditioned air blown out from the exhaust portion of the air conditioner. It may be done.

  In another aspect of the present invention, the upper wall may have a substantially box-like shape, and a removable lid may be provided on the upper wall.

  In another aspect of the present invention, a heat insulating material may be disposed on the wall surfaces of the first space and the second space.

  The present invention is a chamber box used in a ventilating air conditioning system for a building having an underfloor space surrounded by a base, the ground and a floor, and an upper floor space thereabove.

  The chamber box includes a first space having a first inlet for taking in air in the space below the floor, a second space into which air conditioned by an air conditioner is introduced, the first space, and the second space. It is characterized in that it includes an open / close portion for communicating or blocking, and the exhaust port is open to the first space.

  Such a chamber box can selectively supply "air which has been heat-exchanged with the ground" or "mixed air of air which has been heat-exchanged with the ground and air conditioned by the air conditioner" to the floor space. It is.

  As mentioned above, the temperature of the air in the underfloor space is lower than the outside air in summer and higher than the outside air in winter. Therefore, for example, when it is not necessary to actively use the air conditioner, it is desirable to switch the open / close unit to shut off the first space and the second space in the chamber box. Thereby, the air of the underfloor space introduced into the first space can be supplied to the above-floor space. Thereby, ventilation and air conditioning of the space above the floor of the building are simultaneously realized by using the air in the space below the floor heat-exchanged with the ground.

  On the other hand, in summer and winter, it is desirable to switch the opening and closing part of the chamber box to connect the first space and the second space. Thereby, in the first space, the air in the underfloor space and the air more actively conditioned by the air conditioner are mixed and supplied to the on-floor space. Thereby, more comfortable air conditioning can be realized while performing ventilation. In this case, since the air in the space below the floor is used for ventilation, the temperature change due to ventilation can be suppressed to a smaller value than when the other outside air is directly introduced. As a secondary effect, installation of a heat exchanger unit or the like for preventing heat loss can be omitted separately from the path for introducing the outside air for ventilation.

It is a sectional view of a building for explaining a ventilation air conditioning system of one embodiment of the present invention. It is an expanded sectional view of the chamber unit of this embodiment. It is an expanded sectional view of the chamber unit of other embodiment.

Hereinafter, an embodiment of the present invention will be described based on the drawings.
FIG. 1 conceptually shows a cross-sectional view of a building 2 to which the ventilation air conditioning system 1 of the present embodiment is applied. As shown in FIG. 1, in the present embodiment, a house H is shown as the building 2. In order to enhance the air conditioning effect, it is desirable that the house H is an industrialized house with excellent heat insulation performance, light shielding performance and air tightness performance.

  The house H comprises an underfloor space 3 and an overfloor space 4. Underfloor space 3 is a non-residential space surrounded by foundation 5, ground 6, and floor 7. The on-floor space 4 is a space provided above the below-floor space 3, and in this embodiment, is divided into a plurality of living room spaces 4A to 4C and a non-living room space 4D such as a washroom and a toilet.

  The ventilation air conditioning system 1 is capable of supplying the base air supply port 8 for introducing outside air into the underfloor space 3, the chamber box 9 disposed in the underfloor space 3, and the air in the chamber box 9 to the overfloor space 4. Device 10 is included. Although the ventilation air conditioning system 1 of the present embodiment further includes a heat collecting device 22, this device is an optional element.

  The base air supply port 8 is one opening provided at the rising portion of the base 5. Outside air is taken into the underfloor space 3 through the base air supply port 8. In the present embodiment, the base air supply fan 11 is provided, for example, in the vicinity of the base air supply port 8 in order to actively introduce the outside air into the underfloor space 3. The base 5 is preferably thermally insulated from the outside air by a heat insulating material such as a foamed resin (not shown).

  The outside air supplied to the underfloor space 3 exchanges heat with the ground heat via the ground 6 of the underfloor space 3. Thus, the air in the underfloor space 3 may have a temperature lower than the outside air in summer and higher than the outside air in winter. The ground 6 of the underfloor space 3 is finished with, for example, concrete between soils.

  An example of the chamber box 9 is shown enlarged in FIG. In addition, since the chamber box 9 of FIG. 1 is shown notionally, it does not necessarily correspond with the chamber box 9 shown by FIG. As shown in FIG. 2, the chamber box 9 is substantially box-shaped, and includes a first space 9A, a second space 9B, and an opening / closing portion 9C provided therebetween. The chamber box 9 is used as a space for storing air for supplying the on-floor space 4.

  The first space 9A is provided on one end side of the chamber box 9 in the horizontal direction. The first space 9A is completely accommodated in the underfloor space 3. A heat insulating material 12 is disposed on the wall surface of the chamber box 9 that divides the first space 9A. As a result, the first space 9A is thermally insulated, and heat dissipation to the outside can be prevented.

  In the first space 9A, a first inlet 13 for taking in the air of the underfloor space 3 is provided. Therefore, the air in the underfloor space 3 (that is, the outside air heat-exchanged with the ground cooling heat) is introduced into the first space 9A from the first inlet 13. In this example, the first inlet 13 is provided on the upper surface side of the first space 9A, but the position can be arbitrarily determined. In the present embodiment, the opening and closing unit 30 is provided in the first inlet 13. The open / close unit 30 is, for example, an electrically controllable damper, and is normally open so that the first space 9A and the underfloor space 3 communicate with each other.

  In the first space 9A, a second inlet 19 for taking in the outside air warmed by the heat collector 22 is further provided. Therefore, the outside air warmed by the heat collector 22 can also be taken into the first space 9A. In the present embodiment, the second inlet 19 is provided with an open / close unit 21. The open / close unit 21 is, for example, an electrically controllable damper, and is usually closed so as to shut off the space between the first space 9A and the heat collector 22. On the other hand, when the air from the heat collecting device 22 is taken into the first space 9A of the chamber box 9, for example, the second inlet 19 is opened by operating the open / close unit 21. In this case, the first inlet 13 may be closed by operating the opening / closing unit 30.

  Further, the first space 9A is provided with an exhaust port 14 for discharging the air therein. The exhaust port 14 is provided, for example, on the side surface of the first space 9A. One end 10Ai of the duct 10A of the air supply device 10 is connected to the exhaust port 14. These will be described in detail later.

  The second space 9B is provided on the other end side of the chamber box 9 in the horizontal direction. In the present embodiment, the upper wall 17 that defines the second space 9B is exposed to the on-floor space 4 from the opening 7a provided on the floor 7. It is desirable that the upper wall 17 be provided with, for example, a removable lid 15. By removing the lid 15, there is an advantage that inspection and maintenance in the chamber box 9 can be easily performed from the floor space 4 side.

  An air conditioner (air conditioner) 16 is accommodated in the second space 9B. In order to accommodate the air conditioner 16, the second space 9B is configured, for example, as having a larger volume than the first space 9A.

  The air conditioner 16 of the present embodiment is a general household separate-type air conditioner, and the indoor unit is disposed in the second space 9B. The outdoor unit (not shown) is installed outside the building 2. The air conditioner 16 has an intake portion 16a for sucking in air, and an exhaust portion 16b for exhausting air that has been heat-exchanged with the refrigerant inside. Therefore, by operating the air conditioner 16, the air-conditioned air is introduced into the second space 9B. It is desirable that the heat insulating material 12 be disposed also on the wall surface of the chamber box 9 that divides the second space 9B. As a result, the second space 9B is thermally insulated, and heat flow can be prevented.

  In the present embodiment, an on-floor air inlet 18 for supplying the air in the on-floor space 4 to the intake portion 16 a of the air conditioner 16 is provided in the second space 9 B of the chamber box 9. The floor air inlet 18 is provided, for example, as a suction grill on the upper wall 17 of the chamber box 9. As a result, the air in the floor space 4 is supplied to the air intake portion 16a of the air conditioner 16 in the second space 9B via the floor air inlet 18. This serves to prevent a short circuit of the air conditioner 16 in the second space 9B which is a smaller space than a room or the like. In order to exhibit such an action more reliably, the shielding part 40 for preventing mixing of the air of the space 4 on the floor and the air-conditioned air which blows off from the exhaust part 16b of the air conditioner 16 is further provided. It may be done.

  The shielding unit 40 is, for example, a damper whose operation can be controlled, and is a blocking position for blocking the intake 16a and the exhaust 16b of the air conditioner 16, and a communication position for communicating the intake 16a and the exhaust 16b. It is configured to be switchable.

  An opening / closing portion 9C is provided between the first space 9A and the second space 9B. The first space 9A and the second space 9B communicate with each other or are blocked by the opening / closing portion 9C. For example, a damper or the like operated by electric control is preferably used as the opening / closing portion 9C, and the operation position is switched by a control device or the like (not shown).

  When the opening and closing portion 9C is switched to the blocking position, the first space 9A and the second space 9B form two independent spaces. In this case, only the "air in the underfloor space 3 heat-exchanged with the ground 6" is supplied to the first space 9A of the chamber box 9. On the other hand, when the opening / closing part 9C is switched to the communication position, the first space 9A and the second space 9B substantially constitute one space in communication with each other. In this case, when the air conditioner 16 is operated in the first space 9A of the chamber box 9, "air in the underfloor space 3 heat-exchanged with the ground 6" and "air conditioned by the air conditioner 16" "Mixed air" is supplied.

  As shown in FIG. 1, the air supply device 10 includes a duct 10A, a fan 10B for air supply, and an air purification device 10C.

  The duct 10A has one end 10Ai connected to the exhaust port 14 of the chamber box 9 and the other end 10Ao located at the ceiling of each living room 4A, 4B and 4C of the on-floor space 4 and the non-living room 4D such as toilet and washroom. doing. Each other end 10Ao of the duct 10A communicates with each living room space 4A, 4B and 4C and a non-living room space 4D such as a toilet or a washroom via a damper 20 capable of adjusting the amount of air passing therethrough. Further, in the present embodiment, two systems for the first floor and the second floor are provided as the duct 10A, but these may be integrated into one system.

  The air supply fan 10B is provided between one end 10Ai and the other end 10Ao of the duct 10A. The fan 10B generates a forced air flow from one end 10Ai of the duct 10A to the other end 10Ao. Therefore, by operating the fan 10B, the air in the first space 9A of the chamber box 9 is fed from the exhaust port 14 to the other end 10Ao of the duct 10A.

  The air purification device 10C is provided, for example, between one end 10Ai and the other end 10Ao of the duct 10A, and in the present embodiment, is provided on the upstream side of the fan 10B. As the air purifier 10C, various types of air purifiers can be adopted as long as they can remove pollen, particulate matter, dust and the like from the air in the duct 10A.

  In this embodiment, the fan 10 </ b> B and the air purification device 10 </ b> C are both disposed in the underfloor space 3. This enables effective use of the space 4 on the floor.

  Furthermore, the heat collection apparatus 22 is provided in the ventilation air-conditioning system 1 of this embodiment. The heat collecting device 22 is an air heat collecting type using natural energy, and for example, the heat collecting portion 22 a provided on the roof and the outside air warmed by the heat collecting portion 22 a are taken as the first space 9 A of the chamber box 9. And a duct 22b for supplying the

  The heat collection part 22a comprises a glass heat collection part installed so as to be able to introduce outside air between the roof and the roof. The outside air is warmed by sunlight transmitted from the glass heat collector. The outside air is sent to the chamber box 9 through the duct 22b.

  The duct 22 b is connected at one end to the heat collecting portion 22 a and at the other end to the second inlet 19 (shown in FIG. 2) provided in the first space 9 A of the chamber box 9. Although not shown, a fan may be provided in the middle of the duct 22b to actively generate the flow of air from one end to the other end.

  According to the ventilation air conditioning system 1 of the present embodiment configured as described above, ventilation on the floor space 4 can be performed. In this case, for example, the opening / closing portion 9C of the chamber box 9 is switched to the blocking position, the first space 9A and the second space 9B are blocked, and the fan 10B of the air supply device 10 is operated.

  That is, after the air in the first space 9A of the chamber box 9 is cleaned from the exhaust port 14 via the duct 10A and the air purification device 10C, the air in the first room 9A is on the floor of each living room space 4A to 4C via the damper 20. It is supplied to the space 4. Also, according to the amount of the supplied outside air, for example, the air in the floor space 4 is discharged to the outside by the exhaust fan 50 provided in the floor space 4. Air (outside air) of the underfloor space 3 is introduced into the first space 9A of the chamber box 9 from the first inlet 13. Therefore, the floor space 4 such as each of the living room spaces 4A to 4C and the non-living room space 4D is ventilated with the cleaned outside air by such operation.

  Further, as described above, the temperature of the air heat-exchanged with the ground 6 in the underfloor space 3 is lower than the outside air in the summer and higher than the outside air in the winter. Therefore, in the early stage of summer or winter when it is not necessary to actively use the air conditioner, temperature control of the space 4 above the floor 4 without using the air conditioner 16 by utilizing the air of the space 3 below the floor It is possible to cool or slightly warm). Therefore, the air conditioning cost can be reduced.

  In summer and winter, it is desirable to switch the opening / closing part 9C of the chamber box 9 to the communication position to connect the first space 9A and the second space 9B. As a result, in the first space 9A, the air in the underfloor space 3 and the air more actively conditioned in the cooling or heating operation of the air conditioner 16 are mixed. Then, the mixed air is supplied to the on-floor space 4 by the air supply device 10. Thereby, air conditioning of the space 4 above the floor can be realized more positively while ventilating.

  Moreover, since the air in the underfloor space 3 is used as the outside air for ventilation as the mixed air, the temperature change due to ventilation is suppressed to be smaller than when the outside air other than the underfloor space 3 is directly introduced. be able to. In addition, as a secondary effect, for example, installation of a heat exchanger unit or the like that prevents heat loss can be omitted separately from the path for introducing the outside air for ventilation.

  In addition, when the air conditioner 16 is in a stopped state, for example, by opening the shielding portion 40, part of the air in the floor space 4 can be sent to the air supply device 10 via the chamber box 9. In this case, purification can be performed while circulating the floor space 4.

  Furthermore, in the winter, the outside air heated by the heat collector 22 may be hotter than the air in the underfloor space 3. In such a case, the first inlet 13 is closed by the opening / closing unit 30, and the second inlet 19 is opened by the opening / closing unit 21. As a result, the hotter outside air warmed by the heat collector 22 is introduced into the first space 9A of the chamber box 9 in place of the air in the underfloor space 3. Therefore, it is possible to adjust the on-floor space 4 to a higher temperature using only natural energy while ventilating.

  Although not illustrated, in the ventilation air conditioning system 1 of the present embodiment, for example, a motion sensor or a temperature sensor may be provided in each of the living rooms 4A to 4C. And the air volume of each damper 20 can also be adjusted individually based on the detection signal of these sensors.

  FIG. 3 shows a cross-sectional view of the chamber box 9 of another embodiment. In FIG. 3, the elements common to the embodiment of FIG. 2 are denoted by the same reference numerals. The shielding part 40 of the chamber box 9 of this embodiment includes a first shielding part 40a provided on the upper side of the exhaust part 16b of the air conditioner 16, and a second shielding part 40b provided on the lower side of the exhaust part 16b. Contains. The first shielding portion 40a and the second shielding portion 40b are preferably covered with a heat insulating material.

Due to the above shielding portion 40, the space on the right side of the opening / closing portion 9C in the view of the chamber box 9 is a conditioned air region 9B1 as a second space 9B into which only the air conditioned by the exhaust portion of the air conditioner 16 is introduced. And an on-floor air area 9B2 in which the air of the on-floor space 4 is present. The air conditioner 16 is substantially exposed only to the exhaust portion 16b in the second space 9B, and the other portion is exposed to the floor air area 9B2. In such a chamber box 9, the air conditioner 16 can be exposed to air at the temperature of the intake portion 16 a (in other words, only the exhaust portion 16 b is exposed to the second space). The temperature sensor built in can be used effectively. If the temperature sensor of the air conditioner 16 is affected by the temperature of the second space 9B, there is a risk that the operation will be unintended.

  Furthermore, in this embodiment, the floor air inlet 18 is provided not at a position directly above the air conditioner 16, but at a position shifted in the horizontal direction. Thereby, the air conditioner 16 can be protected from falling of water droplets and the like from the indoor side.

  Although one embodiment of the present invention has been described in detail above, the present invention is not limited to the above-described embodiment, and can be modified in various aspects.
