DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to the setting of a balance between the position of an intake port serving as an outdoor air intake port in an independent room such as an office, the position of a forced exhaust ventilation fan at an exhaust port, and the amount of exhaust air. Also, the present invention relates to a method of totally recirculating indoor air, in which air is introduced into the indoor air while the room is being recirculated all the way to ventilate the room so that the indoor temperature is kept uniform.

2. Description of the Related Art In the case of ventilating the interior of a building such as a living room or an office room of a house, a ventilating fan for exhaust is conventionally mostly installed on a ceiling or a wall. It relies on incoming air and does not take into account any special inlets. For this reason, the ventilating fan installed at an angle, the air renewal rate in the room only worked 10% in the past,
Therefore, at present, the room temperature conducted by the air is not uniform because there are many irregularities depending on the place. In addition, most of the conventional air conditioners, regardless of the heat source, discharge the created air into the room at an angle selected by a wind direction guide plate or the like to a fan that incorporates the generated air, so that the uniform air Diversion has not been completed. Therefore, the temperature in the whole room cannot be kept constant. Also, according to the common sense so far, if the natural air inlet is installed adjacent to the ventilation fan as shown in FIG. 1, the outside air of the inflow chamber is directly short-circuited as shown by a dotted short-circuit flow a shown in the figure. It was common sense that the room was not refluxed and the ventilation efficiency was only about 10%. That is, even if the required temperature and ventilation volume of the entire room can be calculated, the method of injecting the outdoor air only with the power of the exhaust ventilation fan and completely recirculating the room air along the ceiling and walls is a conventional technology. There was no solution.

[0003]

Generally, to maintain the room temperature uniformly while renewing the interior of a building by effectively renewing the ventilation of the interior of the building effectively promotes the heat conduction and transmission effect because the heat conduction and transmission effect is caused by air. For this purpose, the room air must flow uniformly. In other words, it is important how effectively the outdoor air introduced into the room is caused to flow in the room while the indoor air is taken in and the indoor air is renewed.

As the nature of air, warmed air becomes lighter and rises, and cooled air becomes heavier and falls. It also has the habit of moving relatively fast along walls and ceilings. From this habit, in order to make the indoor temperature uniform while renewing the ventilation with the outside air, the positional relationship between the inlet to the room and the outlet to the outside and the balance between the speeds are important issues. And natural intake (negative pressure) by forced exhaust rather than natural exhaust (positive pressure) by forced intake into the room by a ventilation fan etc.
The point of solving the problem is that the method can average the indoor air. The present invention solves the above problems.

[0005]

SUMMARY OF THE INVENTION The present invention ventilates a room such as a living room of a house or an office, and at the same time equalizes the room temperature. The room air is supplied to an exhaust port B provided at the upper part of the wall. A forced exhaust ventilation fan A for forcibly exhausting air is installed, and an air inlet C for allowing air to flow in naturally from the outside is provided on a wall surface or a ceiling surface immediately above the air for replenishing the interior of the room as a result of the forced exhaust. The air opening C is provided with an adjustment opening / closing plate 1 for adjusting the wind direction, and the balance between the amount of air exhausted by the forced exhaust ventilation fan A and, as a result, the amount of air intake from the air inlet C that naturally flows in due to negative pressure is considered. Then, an opening is set so as to run on the ceiling surface at a pre-calculated speed, and the inflow air flow p is circulated to the ceiling, the wall, the floor, and the wall sequentially and totally recirculated. The renewal rate of indoor air is 90 Thereby allowing more, by using this ventilation system, in which characterized in that to keep the indoor temperature uniform interlocked with the movement of air.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION The present invention sets the balance between the amount of exhaust air forcibly exhausted by a ventilation fan and the amount of outdoor air that naturally flows in due to a decrease in indoor air pressure resulting therefrom. By arranging C, the inflow velocity of the air from the inlet C is increased to create a totally recirculated inflow airflow p,
By using the wind speed to create an accurate air guide b in the room to keep the room temperature uniform at the same time as ventilation, when installing the forced exhaust ventilation fan A in the exhaust port B, firstly, the number of operating personnel and use The calorific value of office equipment, lighting equipment, operating air-conditioning equipment, etc. is accurately calculated, and a ventilation fan with an exhaust capacity of 30 to 50% of the required air volume required for the purpose of forced exhaust is shown in FIGS. As shown in FIG. A plurality of forced exhaust ventilation fans A may be provided depending on the exhaust capacity, but in the case of FIG. 1, they are arranged on the same wall as evenly as possible. In addition, when the ceiling width is large as shown in FIG. 3 and the ceiling has adjustable inlets Da and Db for taking in natural air in a lump, the ceiling may be provided on both sides of the wall parallel to the inlet or only on one side. Good. However, since the ventilation volume differs between summer and winter, it is desirable to use wiring that can control the number of operating units.

[0007] When it is desired to form an air guide p as shown in FIG. 1, the air inlet through which air naturally flows in is opened on the wall surface immediately above the exhaust port B in which the forced exhaust ventilation fan A is installed. At this time, the opening area is set so that the inflow air flow b causes the wind to run below the ceiling of the room and that the initial velocity at the inlet opening is 3 m / sec or more. This opening is provided with an adjustable opening / closing plate 1 whose size can be increased or decreased in order to cope with an increase or a decrease in ventilation volume in summer or winter. Instead of a band, it is made into a box shape at intervals of 3 m so that the air flows in a lump.

[0008] By satisfying these conditions, the natural air inlet to the forced exhaust port is not a short-circuit discharge such as a short-circuit flow a shown by a broken line in FIG. While mixing the air, the inflow airflow b and the air guide p accompanying the airflow b can be made to go around the room using only the exhaust power to the ceiling, the wall, the floor, the wall, and the exhaust port.

In addition, when the indoor space is relatively wide and the ceiling height is high, the air inlets for the outdoor air are shown in FIG.
As shown in FIG. 2B, it is mounted downward on the ceiling surface, or is mounted so as to run on the ceiling facing the wall surface as shown by the inlets Ca and Cb in FIG. At this time, the initial speed, the opening area, and the adjustment plate and the opening are formed in a box shape at 3 m intervals are the same as in the case of FIG. In any case, by using the wind speed of the outside air of the suction chamber with the balance between the exhaust power of the ventilation fan and the natural air intake,
Simultaneously with the ventilation, a uniform air conduction is created in the room, thereby equalizing the room temperature and realizing energy saving.

[0010]

As described above, according to the present invention, the outdoor air naturally introduced by only the power of the forced exhaust ventilation fan for forcibly exhausting air is completely recirculated along the ceiling, the wall, and the floor, so that the interior of the room is effectively used. At the same time, there is an effect that the indoor temperature is kept uniform and there is an effect that energy saving can be realized.
