BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described below.
This will be described with reference to the drawings. FIG. 1 shows the configuration of a general two-story house and an air conditioner installed in this house.

Here, the air conditioning unit 10A for the first floor is
It is arranged in the ceiling 12 of the shared space 11A on the first floor, such as the corridor on the first floor and the stairs leading from the first floor to the second floor. Then, the second-floor air conditioning unit 10B is arranged in a so-called attic 13 which is the ceiling of the second-floor shared space 11B such as a corridor and stairs landing on the second floor.

The first and second floor air conditioning units 10A, 10
B is an outdoor unit 14 that is arranged outside the house and accommodates an outdoor heat exchanger (not shown), a blower, a compressor, and the like.
And a refrigerant pipe 15 are connected to form a refrigeration cycle.

The first floor air conditioning unit 10A is connected to a pair of outlet ducts 16 on both side surfaces thereof. The tips of these ducts 16 extend to the rooms R on the first floor.

Although the room R is assumed to be a so-called living room here, the categories of this room include kitchen, bathroom,
There is no problem even if you include the toilet and toilet. However, it is desirable to install a ventilator with simultaneous air supply and exhaust in the kitchen, and an exhaust ventilator with exhaust air in bathrooms, washrooms, toilets and the like.

Each room R on the first floor is provided with a ventilation unit 18 which will be described later on the ceiling 17 thereof, and the tip of the duct 16 is connected to each ventilation unit 18. A pair of outlet ducts 16 are connected to the side surfaces of the second-floor air conditioning unit 10B, and the ends of these ducts extend to the rooms R on the second floor. This ceiling 17 is also provided with a ventilation unit 18 described later,
The tip of the duct 16 is connected to each ventilation unit.

In addition, here, the above-mentioned second floor air conditioning unit 1
The natural symbiotic ventilation unit 20 is arranged so as to be adjacent to 0B. Shared space 11B of this ventilation unit 20
A ventilation opening (not shown) is provided on the surface facing the
A duct 21 that opens from the eaves of the house to the outside of the house is connected to the facing surface of 3.

The natural symbiotic ventilation unit 20 temporarily takes in fresh outside air into the shared space 11B, for example, during the summer nights or the intermediate seasons (when the temperature is low and the humidity is low). The heat of the attic 13 is exhausted when the temperature is high during the daytime in summer. In the middle season, the polluted air in each room R is discharged through the shared space 11B and fresh outside air is taken in. In addition, the heat of the attic 13 which is warmed up in winter is once introduced into the common space 11B to be used as an auxiliary heating heat source.

FIG. 2 schematically shows this air conditioner. Air-conditioning unit 10 showing generically the first floor and the second floor
The decorative panel 21 constituting the lower surface is attached to and exposed on the ceiling 17 of the common space 11 which is a generic name for the first floor and the second floor.

The decorative panel 21 is provided with a suction port 22 and communicates with the common space 11. A filter (not shown) is replaceably attached so as to face the suction port 22.

In the air conditioning unit 10, the indoor heat exchanger 2
3 and a fan 24 are housed. The suction side of the fan 24 faces the suction port 22 of the decorative panel 21 via the indoor heat exchanger 23, and the blow side of the fan 24 faces the discharge port 22a provided on the side surface of the unit and connected to the duct 16. .

As shown in FIG. 5, the ventilation unit 18 is provided with a suction port body 18a to which the duct 16 is connected on the side surface thereof, and the lower surface portion is exposed from the ceiling 17 of the room R into the room. It is the outlet 18b. An auxiliary suction port 18c is provided on the side of the blowout port 18b, and a room temperature sensor 25 is attached thereto.

In addition, the ceiling 17 on the lower surface of the ventilation unit
A decorative panel 18d is attached to the. The sirocco fan 26 is housed in the ventilation unit 18. The sirocco fan 26 sucks air from the end face direction and blows it from the circumferential direction as it rotates. The suction side of the sirocco fan 26, the suction port 18a and the auxiliary suction port 18c to which the duct 16 is connected, and the room temperature sensor 2
5 is located, and the outlet 18b faces the outlet side.

Incidentally, the door facing the shared space 11 of each room R, for example, the door, needs a communicating portion 27 that communicates with the shared space such as undercut and louver, and this communicating portion also constitutes the air conditioner. It becomes a requirement.

In the air conditioner thus configured, the compressor of the outdoor unit 14 described above is driven to start the refrigeration cycle operation. In the air conditioning unit 10, the fan 24 is driven to guide the heat exchange air to the indoor heat exchanger 23 to perform the heat exchange action.

The air that has been heat-exchanged by the indoor heat exchanger 23 is blown to the duct 16 through the blowout port 22a, and this time, the sirocco fan 26 arranged in the ventilation unit 18 is blown.
Is efficiently sucked into the ventilation unit 18. Then, the air is blown into the room R from the blowout port 18b of the ventilation unit 18 to perform the air conditioning.

The heat-exchanged air after air conditioning is guided from the room R to the common space 11 through the communication part 27 facing the common space 11, and once collected there, it is attached to the ceiling 17. Suction port 22 of makeup panel 21
Is sucked into the air conditioning unit 10 and circulates in the above cycle.

On the other hand, the room temperature sensor 25 has the auxiliary suction port 1
The room temperature is detected from the heat exchange air flowing through 8c, and the detection signal is sent to a control circuit (not shown). The control circuit performs control so that necessary operating conditions can be obtained from the difference between the temperature detection signal and the set temperature set for the remote controller or the like.

For example, the operating frequency of the compressor of the outdoor unit 14 is adjusted, the rotation speed of the fan 24 provided in the air conditioning unit 10 is adjusted to control the air volume,
The air volume is controlled by adjusting the rotation speed of the sirocco fan 26 provided in the ventilation unit 18.

As described above, the new air conditioner is provided with the ventilation unit 18, in which the sirocco fan 26 is arranged and driven at the time of air-conditioning operation, so that the static pressure is reduced as compared with the conventional structure. It can be as high as 3-5 mmAq.

Therefore, the pressure loss from the air conditioning unit 10 to the air outlet 18b opening in each room R can be small, and the rotation speed of the fan 24 of the air conditioning unit 10 can be made lower than that of the conventional air conditioning unit. Reduction can be obtained. Alternatively, the diameter of the fan 24 can be reduced to reduce the size of the air conditioning unit 10 itself.

The concrete numerical values will be described as follows. For example, when heating two rooms A and B at the same time, the set temperature of room A is 25 ° C, the detected room temperature is 15 ° C, and the set temperature of room B is 22 ° C.
It is assumed that the detected room temperature is 15 ° C at ° C.

At this time, the control circuit sends a control signal for making the fan 24 in the air conditioning unit 10 operate in a strong wind, and causes the ventilation unit sirocco fan 26 in the room A to operate at 100%.
Drive and drive the ventilation unit Sirocco fan 26 in room B to 60
Control the air flow rate so that it will be driven. Therefore, the room temperature can be matched with the set temperature of each room in a short time.

Although the air conditioning unit 10 and the ventilation unit 18 are arranged in the ceiling 12, the present invention is not limited to this, and the air conditioning unit 10 is arranged under the floor 28 as shown by a chain double-dashed line in the figure. Alternatively, the ventilation unit 18 may be connected from here via the duct 16.

Although the ventilation unit 18 is arranged on the ceiling 17, it is not limited to this, and it may be mounted on the wall of the room R, embedded in the wall in a so-called built-in manner, or arranged on the floor. You can also

An air conditioner as shown in FIG. 3 may be used. (Note that, except for the components described below, the other parts are the same as those described above, and therefore, the same numbers are given here and a new description will be omitted. The same applies to the following.) A damper 29 is provided at each outlet 22a of the air conditioning unit 10 shown in FIG. The opening amount of each damper 29 is adjusted by a drive motor (not shown) according to a control signal from the control circuit. For example, in the case of heating the four rooms of the C room, the D room, the E room, and the F room, the control as shown in Table 1 is performed.

[0046]

[Table 1]

Ventilation unit 1 in chambers C, D and E at this time
The dampers 29 in the ducts 16 connected to 8 are controlled to be fully opened, and only the dampers 29 in the ducts 16 connected to the ventilation unit 18 in the F chamber are controlled to be fully closed.

Further, the control circuit operates 90% of the sirocco fan 26 in the ventilation unit 18 of the room C, operates 30% of the ventilation unit sirocco fan 26 of the room D, and operates 100% of the ventilation unit sirocco fan 26 of the room E. , The ventilation unit sirocco fan in the F room is controlled to stop.

That is, since the room temperature in the F room has already reached the set temperature of 23 ° C., the damper 29 is fully closed to prevent heat exchange air from flowing from the duct 16 to the ventilation unit 18, and The sirocco fan 26 in the ventilation unit 18 is stopped and no air is blown out.

In rooms C through E, except room F,
The damper 29 and the sirocco fan 26 are controlled in a necessary amount so that each room temperature reaches and rises to the set temperature. Therefore, the room temperature can be matched with the set temperature of each room in a short time.

An air conditioner as shown in FIG. 4 may be used. Here, the suction port body 18 of the ventilation unit 18
a is a damper 29, or V that has the same function as the damper
Install the AV unit.

This device also operates in exactly the same way as the air conditioner described above with reference to FIG. Then, the damper 29 or the VAV unit and the sirocco fan 26 in the ventilation unit 18 are controlled according to the set temperature with respect to the room temperature.

An air conditioner as shown in FIG. 6 may be used. (A part of the drawing is omitted. The same applies to the following.) In this case, the air conditioning unit 10 and the ventilation unit 18 are provided.
Has exactly the same shape and structure as described above,
A chamber box 30 was provided instead of the duct 16.

That is, the chamber box 30 is covered from the air conditioning unit 10 to each ventilation unit 18. This chamber box 30 is used for the air conditioning unit 1
0 has a so-called tunnel-like branching portion with respect to the ceiling 17 so as to cover the upper surface portion and a part of the side surface portion and to cover the upper surface portion and both side surface portions of each ventilation unit 18.

As a matter of course, all of the inner surface side of the chamber box 30 is adhered with a heat insulating material and has a heat insulating structure for the attic 12, which means that the duct 16 described above has a heat insulating structure. It is similar to that.

With such a configuration, the air conditioning unit 1
The heat exchange air blown from the blowout port 22a of 0 is guided along the chamber box 30 and blown from each ventilation unit 18 to each room R. That is, the same operation as that of the air conditioner described above is performed.

Since the chamber box 30 is provided instead of the duct, the cross-sectional area of the flow path for guiding the heat exchange air can be made large, and therefore the pressure loss to the outlet 18b for each room R can be increased. Can be further reduced to reduce the fan rotation speed and the fan diameter.

In the air conditioner having the chamber unit 30 as well, the air conditioning unit 10 is arranged under the floor, and the ventilation unit 18 arranged on the ceiling, wall or floor of the room R is covered with the chamber unit 30. You may do it.

An air conditioner as shown in FIG. 7 may be used. This is a configuration in which the damper 29 is arranged in the chamber box 30 described above and on the suction side of the ventilation unit 18.

Also here, the rotation speed of the sirocco fan 26 and the opening degree of the damper 29 in the ventilation unit 18 are adjusted based on the difference between the set temperature and the detected room temperature, and the room temperature of each room R is immediately set to the set temperature. It is possible to match and finely control the room temperature. For example, there is room temperature control as shown in Table 2.

[0061]

[Table 2]

That is, when heating three rooms of the G room, the H room and the I room, the set temperature of the G room is 25 ° C and the detected room temperature is 15 ° C. The room temperature is set to 22 ° C and the detected room temperature is 15 ° C. It is assumed that the set temperature of the room I is 23 ° C and the detected room temperature is 23 ° C.

At this time, the control circuit controls the fan 24 of the air conditioning unit 10 to operate in a strong wind, fully opens the damper 29 communicating with the G room, and causes the ventilation unit sirocco fan 2 to operate.
6 is operated 100%. The damper 29 communicating with the room H is also fully opened, and the ventilation unit sirocco fan 26 is operated by 60%. Only the damper 29 communicating with the I room is fully closed, and the ventilation unit sirocco fan 26 is stopped.

An air conditioner as shown in FIG. 8 may be used. In this case, of course, the air conditioning unit 10 and the chamber box 30 are provided, but the ventilating unit is not necessary except the outlet 18b, and the configuration is simplified.
The chamber box 30 is provided from the air conditioning unit 10 to the outlet 18b opening to the ceiling 17 of each room R.

Even with such a structure, the cross-sectional area of the air passage can be made larger than that in the conventional arrangement of mere ducts, and the pressure loss up to the outlet 18b can be reduced. Has an effect close to that of the form.

An air conditioner as shown in FIG. 9 may be used. Here again, the air conditioning unit 10 and the chamber box 30 are provided, but the ventilating unit is unnecessary except for the outlet 18b, and the configuration is simplified. The chamber box 30 is provided from the air conditioning unit 10 to the outlet 18b opening to the ceiling 17 of each room R. A damper 29 is provided at the outlet 18b.

By using the chamber box 30 described above, the cross-sectional area of the air flow path becomes large, and the outlet 18b
It is of course possible to control the room temperature more finely by adjusting the opening degree of the damper 29, as well as reducing the pressure loss up to.

An air conditioner as shown in FIG. 10 may be used. An air conditioning unit 52 that accommodates the indoor heat exchanger 50 and the fan 51 is arranged in the ceiling space 54 of the shared space 53 such as a corridor. A suction port 55 is provided on the surface of the air conditioning unit 52 facing the common space, and the suction temperature sensor 5
6 is mounted.

A ventilation unit 60 having a fan 59 is arranged on the ceiling 58 of each room 57 so that the air outlet is exposed to the inside of the room. The ventilation unit 60 and the air conditioning unit 52 are communicated with each other via a duct 61.

On the other hand, a communication portion 62 is provided on a door or the like facing the common space 53 of each room 57, and heat exchange air circulates to each other. A room temperature sensor 63 is attached near each communication portion 62.

The room temperature sensor 63 and the suction temperature sensor 56 are electrically connected to the control circuit 64.
A signal indicating the detected temperature is sent to the control circuit 64.

The air conditioning unit 52 is connected to an outdoor unit 65 arranged outside the house through a refrigerant pipe (not shown) so as to form a refrigeration cycle. The outdoor unit 65 accommodates an outdoor heat exchanger 66, a compressor 67, a fan 68, and the like.

The air conditioning unit 52 and the outdoor unit 65 are both electrically connected to the control circuit 64. In the air conditioner configured in this way,
A remote control (remote control panel) 70 as shown in FIG. 11 is attached. The remote controller 70 is a wired or wireless remote controller and is arranged in each room 57 in which the ventilation unit 60 is arranged.

The remote controller 70 has a dual structure in which there is a sub operation surface (not shown) on the back side of the main operation surface 71 which is the surface thereof. To open the sub operation surface, the main operation surface 71 is rotated or slid to be exposed.

On the main operation surface 71, a powerful designation button 72 for designating priority operation and a mode switching button 73 for switching modes such as cooling operation, heating operation and dehumidifying operation.
In addition to the run / stop button 74 and the like, there is a display window 75 formed of a liquid crystal panel. Various buttons such as a wind direction, an air volume setting button, a reservation button, a timer button, and a temperature setting button are arranged on the sub operation surface.

When the operator presses the powerful designating button 72 of the remote controller 70 during the air-conditioning operation, the control circuit 64 designates which room 57 the powerful designating button 72 of the remote controller 70, that is, the preferential operation is designated. Recognizing that,
The number of rotations of the fan 59 of the ventilation unit 60 in the room 57 in which the button is pressed is increased.

Room 5 in which the powerful selection button 72 is pressed
A larger amount of air than the amount of heat-exchanged air guided to the other room 57 is blown to 7, so that the operation is prioritized over the other rooms, and more efficient air conditioning operation is performed. .

The overall control system for the room 57 for which the priority operation is designated by the control circuit 64 is as follows. As one of them, when the control circuit 64 recognizes the room 57 in which the priority operation is designated, the control circuit 64 sets the rotation speed of the ventilation unit fan 59 in the room 57 in which the priority operation is designated to the ventilation of the room 57 in which the priority operation is not designated. The control is performed to increase the rotation speed of the unit fan 59.

Therefore, the room 5 in which the priority operation is designated
The heat exchange air flow rate for No. 7 is larger than the heat exchange air flow rate for the room 57 for which priority operation is not designated,
Priority air conditioning operation is implemented.

As the second, when the control circuit 64 recognizes the room 57 in which the priority operation is designated, the rotation speed of the ventilation unit fan 59 in the room 57 in which the priority operation is not designated is changed to
Control is performed to lower the rotation speed of the ventilation unit fan 59 attached to the room 57 in which priority operation is designated.

Therefore, the room 5 in which the priority operation is designated
The heat exchange air flow rate for No. 7 is larger than the heat exchange air flow rate for the room 57 for which the priority operation is not designated, and the preferential air conditioning operation is performed.

As the third, instead of the ventilation unit 60 equipped with the fan 59 attached to each room 57, the rotation amount is changed based on the control signal of the control circuit 64 as shown in the circle in the figure. It includes a damper unit 69 that accommodates an adjustable damper 69a.

When the control circuit 64 recognizes the room 57 in which the priority operation is designated, the opening degree of the damper 69 of the damper unit 69a provided in the room in which the priority operation is designated becomes the room 57 in which the priority operation is not designated. The opening of the damper 69 of the attached damper unit 69a is controlled to be larger than the opening.

Therefore, the room 5 in which the priority operation is designated
The heat exchange air flow rate for No. 7 is larger than the heat exchange air flow rate for the room 57 for which the priority operation is not designated, and the preferential air conditioning operation is performed.

Fourth, when each room 57 is provided with the damper unit 69, when the control circuit 64 recognizes the room 57 in which the priority operation is designated, the control circuit 64 detects that the damper unit 69 in the room 57 is not designated as the priority operation. Damper 69
The opening degree of a is controlled to be smaller than the opening degree of the damper 69a of the damper unit 69 attached to the room in which the priority operation is designated.

Therefore, the heat exchange air flow rate for the room 57 for which the priority operation is not designated decreases, and the heat exchange air flow rate for the room 57 for which the priority operation is designated relatively increases, so that the priority air conditioning operation is performed. .

In the above embodiment, the powerful designation button 72 of the remote controller 70 is used as the means for designating the preferential operation, but the invention is not limited to this, and the communication section 6
The control circuit 64 may be controlled so as to instruct the priority operation based on the difference between the room temperature sensor 63 provided in No. 2 and the temperature detected by the suction temperature sensor 56 provided at the suction port 55 of the air conditioning unit 52.

For example, as shown in FIG. 12, there are K room, L room, M room, and N room in which the ventilation unit 60 is provided, and the heat exchange air is blown from the air conditioning unit 52. .

When the cooling is stable, the difference between the room temperature of the K room and the suction temperature is 2 ° more than the difference between the room temperature of the other room and the suction temperature.
If C is high, the control circuit 64 automatically selects the K room as the target of the priority operation, and sets the rotation speed of the fan 59 of the ventilation unit 60 to the L room relative to the fan reference rotation speed in the normal operation. Control both M room and N room to -200 rpm. At the same time, the rotation speed of the fan 59 of the ventilation unit 60 in the K room is -40 with respect to the fan reference rotation speed in normal operation.
Control to 0 rpm.

If the difference between the room temperature of the K room and the suction temperature is 1 to 2 ° C. higher than the difference between the room temperature and the suction temperature of the other rooms, the control circuit 64 causes the ventilation unit 60 to be a fan. The rotation speed of 59 is controlled to be -100 rpm with respect to the fan reference rotation speed of the normal operation in each of the L chamber, the M chamber, and the N chamber. At the same time, the rotation speed of the fan 59 of the ventilation unit 60 of the K room is +20 with respect to the fan reference rotation speed of the normal operation.
