A filter 10 for circulating air is installed on the upstream side of the heat exchanger 11 of the indoor unit 7, and a filter 15 for ventilation is used for the heat exchange ventilation unit 1.
It is installed in the outside air intake on the upstream side of the heat exchange element 14 in FIG. Reference numeral 12 is a fan of the indoor unit 7. The symbols from a to i represent the air volume, where a is the air volume in room A, and b
Is the air volume of the B room, c is the air volume of the C room, d is the air volume of the D room, and i is the air volume of the common space 2. The amount of heat supplied to each room A, B, C, D is determined by the product of the amount of airflow and the temperature difference (difference between the room temperature of the room and the room temperature of the common space 2). Must be increased (when cooling, the air volume in a room with a low set room temperature is increased).

FIG. 4 shows the changes over time in the air volume of each room A, B, C, D and the air volume of the common space 2. Air volume a in room A, air volume b in room B, air volume c in room C, and air volume d in room D
The air volumes of the ventilation fans 6a, 6b, 6c, 6d are controlled so that the sum of and becomes approximately equal to the air volume i of the common space 2. In FIG. 4, the air volume of the fan 12 of the air conditioner indoor unit 7 is constant, but even when the air volume of the fan 12 is changed according to the heating capacity (or the cooling capacity) of the air conditioner, each ventilation fan 6a, 6b, 6c. , 6d are controlled to maintain the relationship of a + b + c + d = i.
FIG. 4 shows the case where the set temperature of the room D is higher than that of the other room during heating and the set temperature is not changed (the set temperature is lower than that of the other room during cooling). And in the room C, when the user changes the set temperature with the individual remote controllers 22a, 22b, 22c (however, the room temperature is below the room temperature set during heating, and the room temperature above room temperature above room D). The total air volume (air volume i in the common space)
So that is kept almost constant. However, when the air conditioning capacity of the air conditioner is still sufficient and the air volume of the fan 12 of the indoor unit 7 can be increased, the air volume supplied to the rooms A, B, C, and D can be increased, so that the air volume of the D room is It does not have to be reduced.

FIG. 5 shows the relationship between the air volume Q of the fan and the static pressure P. Since the actual operating point of the fan is in balance with the pressure loss, for example, when the fan is operating in a strong wind, the operating point is (static pressure P1, air volume Q
1). The operating point is medium pressure (static pressure P2, air volume Q2), and weak wind (static pressure P3, air volume Q3). Figure 5
In the above example, the four-step control of strong wind, medium wind, weak wind, and off is shown, but if proportional control is used, the relationship between the air volume and the static pressure is determined steplessly. The pressure loss when air is blown to the structure of the house (shared space, each room, attic, attic, etc.) is almost determined when the construction is completed (strictly when the user starts living), so each room A, B, C, D ventilation fan 6
By detecting the static pressure in the vicinity of a, 6b, 6c, 6d with the respective static pressure sensors 17a, 17b, 17c, 17d, it is possible to measure the air volume of each ventilation fan 6a, 6b, 6c, 6d. it can. Therefore, in FIG.
A static pressure sensor is used to control the air volume in FIG. The first
In the embodiment, the static pressure sensor is used for the fan air volume control, but the fan air volume control may be performed by detecting the rotation speed of the fan.

Second Embodiment A second embodiment will be described with reference to FIGS. 6 to 8. In this embodiment, local ventilation is added. As shown in FIG. 6, a range hood 28 as a local ventilation means is installed in an LDK including a living room, a dining room, and a kitchen, and a toilet 31,
In the washroom 32 and the bathroom 33, pipe fans 34a and 34b are also installed as local ventilation means. In this example, the ventilation air conditioning unit 24 in which the indoor unit 7 of the air conditioner and the heat exchange ventilation unit 13 are integrated is provided in the ceiling 3
It is installed in. The constant ventilation is performed by the heat exchange ventilation unit 13 in the ventilation air conditioning unit 24.

FIG. 7 schematically shows the flow of air. The heat exchanger 10 in the air conditioner indoor unit 7 is connected to the compressor 25, the heat exchanger 26, etc. of the air conditioner outdoor unit 8 by the refrigerant pipe 9. e is the toilet 31,
This is the air volume for local ventilation of the washroom 32, bathroom 33, and the like.

FIG. 8 shows the changes over time in the air volume of each room A, B, C, D, the air volume of local ventilation, and the air volume of the common space 2. The sum of the air volume a of the room A, the air volume b of the room B, the air volume c of the room C, and the air volume d of the room D is approximately equal to the difference between the air volume i of the common space 2 and the air volume e of the local ventilation. , And controls the air volume of each ventilation fan 6a, 6b, 6c, 6d (a + b + c + d = ie). The range hood 28 for local ventilation and the pipe fans 34a and 34b (hereinafter, referred to as fans for local ventilation) have a constant flow rate. When the fan for local ventilation is turned on, the air volume of the fan 12 of the air conditioner indoor unit 7 is increased by almost the same amount as the air volume of local ventilation, so that the air volume i of the common space 2 is increased. The air volumes a, b, c, d of the rooms A, B, C, D do not change. At this time, if only the air volume of the fan 12 of the air conditioner indoor unit 7 is increased, the air conditioning capacity (heating capacity or cooling capacity) will be insufficient, so the compressor 2 of the air conditioner outdoor unit 8 will be insufficient.
The frequency (number of revolutions) of 5 is increased to increase the air conditioning capacity.

Third Embodiment A third embodiment will be described with reference to the control system shown in FIG. Hot air is supplied to each of the rooms A, B, C, and D through the common space 2 during heating, and cool air is supplied during cooling. Therefore, the room temperature of each room is equal to or lower than the room temperature of the common space 2 during heating, and is equal to or higher than the room temperature of the common space 2 during cooling.
Therefore, the individual remote controllers 22a, 22b ...
The setting room temperature (hereinafter, the individual remote control is represented by reference numeral 22) is set to be equal to or higher than the setting room temperature of the centralized remote control 21 in the common space 2, and the setting room temperature of the individual remote control 22 is set at room temperature in the common space 2 during cooling. The following does not make any sense.

In the concentrated mode: There are two cases in the concentrated mode. One is a centralized remote controller 21 and a common space 2
This is a case where the ventilation fans 6a, 6b, 6c, and 6d of the rooms A, B, C, and D are only controlled to set the room temperature and are not controlled. The other one is a case where all the set temperatures of the common space 2 and the rooms A, B, C and D are set by the central remote controller 21. In either case, the individual remote controller 22
All the room temperature settings from are not accepted, and the setting of the central remote controller 21 has priority.

In the individual mode: The room temperature set by each individual remote controller 22 has priority over the room temperature set by the central remote controller 21. During heating, the highest set room temperature of the individual remote controllers 22 is accepted as the set room temperature of the centralized remote controller 21. During cooling, the lowest set room temperature of the individual remote controllers 22 is accepted as the set room temperature of the centralized remote controller 21 (because the heating capacity (cooling capacity) does not always meet the set room temperature, it becomes the heating load (cooling load)). The room temperature is determined when the heating capacity (cooling capacity) is in balance.

The centralized remote controller 21 selects the centralized mode and the individual mode.

Fourth Embodiment In the first embodiment (FIG. 1) and the second embodiment (FIG. 6), the structural frame of the house itself (attic ceiling, attic, staircase, stairwell, wall space) Etc.) is used as the air flow path, but a return duct may be used as the air flow path returning to the air conditioner indoor unit 7. If the airtightness of the house is good, do not use the return duct, but use the ceiling, attic, or underfloor instead of the return duct.

Fifth Embodiment A fifth embodiment will be described with reference to FIG. At the bottom of the door 18 is a louver 20. The pressure loss when the door 18 is closed and the pressure loss when the door 18 is opened are measured in advance, and a change in the pressure loss is detected by the static pressure sensor attached to the ventilation fan. Know that it opened. When the door is opened, the pressure loss in the room is reduced, and the air volume of the ventilation fan is increased. At this time, control is performed so as to suppress the air volume of the ventilation fan in the room with the door opened so that the total (air volume of return air to the air conditioner indoor unit 7) with the air volume of the ventilation fan in the other room becomes substantially constant. As a method of mechanically detecting the open / closed state of the door, there is a method of using a limit switch 35a as shown in FIG. 9 (which is more reliable than the static pressure sensor method, but wiring of the limit switch 35a becomes complicated).

Sixth Embodiment A sixth embodiment will be described with reference to FIG. 9 similarly to the above. Is the door 18 opened by the static pressure sensor of the ventilation fan?
Alternatively, it is extremely difficult to determine whether the window 36 has opened. Therefore, the mechanical limit switches 35b and 35c are used to detect the open / closed state of the window 36. If there is a window opening / closing security system, the information can be used for detection. When the window 36 is opened, the operation of the ventilation fan in the room is stopped. The user opens the window in the air conditioning in the whole building only during the mid-day period when heating and cooling are not required, or when rapid ventilation is required due to air pollution.

Seventh Embodiment A seventh embodiment will be described with reference to FIG. When indoor air is contaminated by cigarette smoke or the like, a gas sensor or the like detects contamination of the air, and the amount of air supplied to the room is increased for a certain period of time to perform intensive ventilation. FIG. 10 shows an example in which the air in the room D is dirty. Since the total air volume is kept almost constant, in order to increase the air volume of the ventilation fan in the D chamber and increase the air supply amount in the D chamber for a certain period of time, the air volumes of the A chamber, the B chamber and the C chamber are respectively decreased. (The sum of the reduced air volumes of A room, B room, and C room is equal to the increased air volume of D room).
