Description

  The present invention relates to a building ventilation facility used for odor countermeasures of an inner corridor type apartment house.

  Conventionally, in many apartment houses, air supply and exhaust are performed from the outer wall side of each dwelling unit such as an outer wall balcony. However, in the case of tower-type apartment houses (super high-rise apartments) that have increased in recent years, especially in the case of the inner corridor type, the outer wall surface of the exclusive unit of the dwelling unit has been decreasing. And the sash and window glass are inserted in the whole outer wall surface, and the part which can be used for air supply / exhaust has become smaller. Therefore, in such a tower type apartment house, it is common to provide an air supply port and an exhaust port on a small balcony set back from the outer wall. Patent Document 1 discloses an example in which a duct connecting portion that takes in outside air from outside the dwelling unit and an exhaust port that sends out the exhaust in the kitchen to the outside of the dwelling unit face the same space.

In this way, when the air supply port and the exhaust port are provided on the same balcony, there is a concern about a short circuit problem in which the exhaust gas discharged from the exhaust port is sucked from the air supply port. As a result, the outside air introduced into the room from the inner balcony (air supply such as 24-hour ventilation, utility ventilation, range hood ventilation, etc.) is easily mixed and contaminated with the room exhaust and the combustion exhaust from the gas water heater. Cause it to occur.
In particular, considering the 24-hour ventilation inside the dwelling units, which has become widespread in recent years, the short circuit becomes a problem in maintaining and securing the air quality of each room.
The present invention has been made in view of the above-mentioned problems, and a main object thereof is to avoid short circuit of air supply and exhaust in an inner corridor type apartment house.

  In addition, there is a ceiling back in the inner corridor of the apartment, and the ceiling back of the inner corridor continues to the ceiling back of each dwelling unit, so it is possible to realize building ventilation equipment using this structure .

  Below, building ventilation equipment is demonstrated divided into 1st Embodiment and 2nd Embodiment.

≪First embodiment: configuration and function of equipment≫
FIG. 1 is a plan view showing a configuration of equipment for carrying out ventilation in an apartment having dwelling units on both sides of an inner corridor. FIG. 2 is a diagram showing equipment for performing ventilation in the apartment of FIG. Fig.2 (a) shows sectional drawing of the structure of the said installation. FIG.2 (b) shows the side view of the structure of the said installation. With reference to FIG.1 and FIG.2, the structure and function of building ventilation equipment are demonstrated.

  As shown in each drawing, dwelling units are arranged on both sides of the inner corridor, and each dwelling unit includes one or more living rooms, a unit bath UB, and an inner balcony IB. In the example of FIG. 1, a staircase and an elevator EV are provided on both sides of the right side portion of the inner corridor in the drawing, and a garbage storage GP is provided at the left end portion of the inner corridor in the drawing.

  The hallway ceiling space HC, which is the ceiling space of the inner hallway, is used as an outside air chamber (partitioned space) for taking outside air and sending it to each dwelling unit and the garbage storage GP. In the example of FIG. 1, an air supply port 1 is provided on the outer wall surface of the building at the right end surface in FIG. 1 of the hallway ceiling space HC, and external air is supplied from the air supply port 1 to the inside of the hallway ceiling space HC by an air supply fan (blower) 3 a. It is supposed to be taken in. A fire damper FD is provided between the hallway ceiling space HC and each dwelling ceiling space LC that is a ceiling back space of each dwelling unit. In addition, an air supply fan 3b is provided on the dwelling unit ceiling space LC side, and the outside air taken into the hallway ceiling space HC is sent into the dwelling unit ceiling space LC. In the dwelling unit ceiling space LC, the duct Da is connected between the fire damper FD and the ventilation opening 5 provided in the ceiling CE of the dwelling unit interior room, and outside air is sent to each room through the duct Da. Also, a fire damper FD is provided between the hallway ceiling space HC and the garbage storage space GP, and the outside air taken into the hallway ceiling space HC is sent to the waste storage space GP.

  Each dwelling unit is provided with an exhaust port 2b provided at an end of the dwelling unit ceiling space LC so as to face the inner balcony IB and the inner balcony IB. The exhaust fan 4a and the duct Db are connected between the exhaust port 2b and the ventilation port 5 provided in the ceiling CE of the water field such as the unit bath UB, and the air in the water field is exhausted to the outside through the duct Db. . In addition, movement of the air from a living room to a water place is performed through the undercut etc. under a door, for example. Further, an exhaust port 2a and an exhaust fan 4 are provided at the left end of the garbage storage site GP, and the air in the garbage storage site GP is exhausted to the outdoors through the exhaust port 2a by the exhaust fan 4.

  The hallway ceiling space HC and each dwelling unit and the garbage storage area GP are partitioned by a fire prevention compartment (fire prevention wall). The fire damper FD is normally opened so that air can freely enter and exit, but is closed so as to block the air flow when a temperature of a predetermined value or more is detected. In other words, it is usually the only air passage, and becomes a fire wall that prevents the spread of fire when the temperature rises, for example, when a fire occurs. In addition, air cannot enter and exit between the hallway ceiling space HC and the inner hallway. This prevents air from entering and exiting between the interior corridor that is not open to the outside and the corridor ceiling space HC. This is to minimize the influence of the outside air taken in by the inner corridor.

  Furthermore, the ventilation equipment of this embodiment is demonstrated in detail. FIG. 3 is a schematic diagram (side view) of a fire damper FD which is one of the facilities. A partition is provided between the hallway ceiling space HC and each dwelling unit and the garbage storage area GP, and a fire damper FD is provided in a part of the partition. The fire damper FD is a rotating plate, and is normally opened by being horizontal as shown in FIG. 3A to allow air to enter and exit freely, but the temperature is a predetermined value (for example, 72 When the temperature is higher than (° C.), the fuse is melted and becomes vertical as shown in FIG. The smoke fire damper SFD that closes even when smoke is sensed in addition to heat has the same mechanism.

  According to the above configuration, the air flow is as follows: outdoor → air supply port 1 → corridor ceiling space HC → fire damper FD → duct Da → ventilation port 5 → room → water field → ventilation port 5 → duct Db → exhaust port 2b. → The house is ventilated and the interior is ventilated. Since the air supply port 1 is located away from the dwelling unit where the exhaust port 2b is provided, it is possible to ventilate the dwelling unit without generating a short circuit for air supply / exhaust.

<< Second Embodiment: Configuration and Function of Equipment >>
FIG. 4: is a top view which shows the structure of the equipment for implementing ventilation in the apartment which has a core in the center part and has a dwelling unit in the one side of the inner corridor provided so that this core may be enclosed. As shown in FIG. 4, a core C is provided as a structure in the center, a blow-off portion 6 is provided around the core C, and an inner corridor and a hallway ceiling space HC are provided around the blow-through portion 6 with a wall interposed therebetween. . And each dwelling unit is arrange | positioned on the circumference | surroundings (one side) of an inner corridor on both sides of a wall, and two sets of elevator EVs and stairs are provided.

  Air supply openings 1b with smoke fire dampers SFD are provided at two locations on the wall between the atrium 6 and the corridor ceiling space HC, and the vents on the wall between the corridor ceiling space HC and the dwelling unit ceiling space LC Is provided with a fire damper FD. Each dwelling unit is provided with an inner balcony IB, and an exhaust port 2 is provided in the inner balcony IB. Here, although not shown in the figure, the duct Da is connected between the fire damper FD and the ventilation port 5 provided in the ceiling of the dwelling unit, as in FIG. 1, and the exhaust port 2b, the unit bus UB, etc. It is assumed that a duct Db is connected to the ventilation port 5 provided on the ceiling CE or the like of the water field.

  Note that an air supply fan that facilitates air intake may be attached to the air supply port 1b and the fire damper FD. The exhaust port 2 may be provided with an exhaust fan that prompts air to be sent out.

  FIG. 5 is a side sectional view showing the configuration of the ventilation facility of the present embodiment. As shown in FIG. 5, a duct D is provided for sending outside air taken in from an air supply port 1 a provided at a predetermined height position of the building to the blow-off portion 6. And the external air sent into the blow-through portion 6 rises and is taken into the hallway ceiling space HC through the air supply port 1b on each floor. As in the first embodiment, the space between the corridor ceiling space HC and the inner corridor is blocked so that air cannot enter and exit, so that the inside of the inner corridor that is not open to the outside can be used. By not taking in the air, the influence of the thermal environment due to the outside air in the inner corridor is minimized.

  The outside air of the blow-off section 6 passes through the air supply port 1b with the smoke fire damper SFD → the corridor ceiling space HC → the fire damper FD → the duct Da → the ventilation port 5 → the living room → the water field → the ventilation port 5 → the duct Db → the exhaust port 2 It is discharged to the inner balcony IB.

  According to the first and second embodiments of the present invention described above, without introducing the outside air from the inner balcony IB into the room, the ceiling of the inner corridor is used as an outside air chamber (a space blocked from others), Introducing fresh outdoor air from outside. Thereby, the outside air introduced for the purpose of the 24-hour ventilation in the exclusive part (residential space) can be made not to be polluted by the exhaust. Then, the ceiling of the inner corridor is used as an outside air chamber and is partitioned from the inner corridor, whereby the influence of the thermal environment due to the outside air in the inner corridor can be minimized. Further, even if a gas water heater is installed on a small balcony in a gas heat source apartment, combustion exhaust gas from the gas water heater is not sucked into the room.
