FIG. 5 is a perspective view illustrating an entire building air conditioning system that does not use a heat exchange type ventilation device, and FIG. 6 is a perspective view illustrating an entire building air conditioning system that does not use a suction chamber.
In FIG. 1, a general detached house will be described as an example, focusing on ventilation air conditioning on the first floor. Although not shown in the figure, the second floor portion has the same configuration, so the description is omitted.

  1 to 3, indoor units 1a and 1b of the air conditioner are indoor units of the same specification, and the indoor units 1a and 1b have indoor unit main body inlets 6a and 6b on the back and bottom surfaces, Are installed in the hallway so that they face each other.

  The indoor units 1a and 1b are connected by a suction chamber 2 on the vertical surfaces of the indoor unit main body suction ports 6a and 6b. An air supply duct connection flange 3 for taking in outside air is provided on the upper portion of the suction chamber 2.

  The lower surfaces of the indoor unit main body suction ports 6 a and 6 b of the indoor units 1 a and 1 b and the lower surface of the suction chamber 2 share the panel suction port 32 of the suction panel 30. Further, a filter 31 is disposed in the suction air passage from the panel suction port 32 to the indoor unit main body suction ports 6a and 6b. The suction panel 30 is in contact with the ceiling member 21 at the peripheral portion on the back side of the design surface, and the indoor units 1a and 1b are suspended from the ceiling and installed.

  In FIG. 3, one filter 31 is used, but as shown in FIG. 4, the filter 31 may be divided into filters 31 a and 31 b corresponding to the indoor units 1 a and 1 b.

  Blowing chambers 4a and 4b are attached to the blowout side of the indoor unit main body formed on the opposite sides of the indoor unit main body suction ports 6a and 6b, and flanges 5a and 5b for connecting the blowout ducts are respectively attached to the blowout chambers 4a and 4b. One or more are attached.

  Inside the indoor units 1a and 1b, heat exchangers 10a and 10b for cooling or heating air, blowers 12a and 12b (for example, sirocco fans) for blowing air, blower motors 11a and 11b for driving these, indoor air The drain pumps 13a and 13b for pumping up the drain generated by the condensation of the humidity of the water and the drain pans 16a and 16b for storing the drain are incorporated.

  Control devices that operate the indoor units 1 a and 1 b and communicate with the outdoor unit 9 are built in the electrical component boxes 15 a and 15 b, and these are arranged inside the suction chamber 2.

  In addition, the light receiving units 18 a and 18 b that receive a command signal from the wireless remote controller are incorporated in the vicinity of the suction panel 30.

  Further, the centralized controller 19 is connected to the indoor units 1a and 1b and the respective control devices for the air conditioning indoor unit on the second floor (not shown) so that the indoor units can be controlled collectively or individually at one place. Yes.

  The outdoor unit 9 is a multi air conditioner outdoor unit that can be operated individually by connecting a plurality of indoor units. The outdoor unit 9 and the indoor units 1a and 1b are connected by refrigerant pipes (gas pipes) 7a and 7b and refrigerant pipes (liquid pipes) 8a and 8b. These refrigerant pipes are connected from the back of the outdoor unit 9. It passes through the wall of the house and is connected to the indoor units 1a and 1b through the ceiling. The refrigerant pipes (gas pipes) 7c and 7d and the refrigerant pipes (liquid pipes) 8c and 8d are connected to an indoor unit that air-conditions the second floor (not shown).

  In the above configuration, the refrigerant pipes connecting the outdoor unit 9 and the indoor units 1a and 1b are provided with refrigerant pipes (gas pipes) 7a and 7b and refrigerant pipes (liquid pipes) 8a and 8b for each of the indoor units 1a and 1b. However, a configuration may be adopted in which the outdoor unit 9 has a refrigerant pipe (gas pipe) and a refrigerant pipe (liquid pipe) common to the indoor units 1a and 1b, and is branched to the indoor units 1a and 1b in the middle. In this case, the electrical component box may be shared or provided individually.

  On the other hand, the heat exchange type ventilator 44 connects the air inlet 42 and the air supply duct connection flange 3 of the suction chamber 2 with a duct in the air supply path, and the ventilation exhaust air intake 40 and the air outlet in the exhaust path. 43 is connected by a duct. The ventilation exhaust suction port 40 is provided with an exhaust fan (not shown). The air supply path of the heat exchange type ventilator 44 includes an air supply fan (not shown).

  The air supply path and the exhaust path described above are heat-exchanged inside the heat exchange type ventilator 44. As a heat exchange method, there are a sensible heat exchange type ventilator for exchanging only sensible heat and a total heat exchange type ventilator for exchanging both sensible heat and latent heat, either of which may be used.

  Moreover, as shown in FIG. 5, the form which does not use the heat exchange type | formula ventilation apparatus 44 may be sufficient. In this case, an air supply fan 45 may be provided somewhere in the air supply path, but in FIG. 5, an air supply fan is provided in the duct between the air supply port 42 and the air supply duct connection flange 3 of the suction chamber 2. The example which provided 45 is shown.

Next, the operation will be described.
In the entire building ventilation air conditioning system configured as described above, room air is taken in from the panel suction port 32 of the suction panel 30 by the blowers 12a and 12b driven by the blower motors 11a and 11b. The room air removes impurities such as dust, dust, odor, and gas by the filter 31, and enters the indoor unit main body inlets 6a and 6b.

  Here, the outside air taken in from the air supply port 42 and heat-exchanged by the heat exchange ventilator 44 is supplied from the upper part of the suction chamber 2 and mixed with the room air. From here, this mixed air is pushed out from the blowers 12a and 12b to the heat exchangers 10a and 10b, where it is cooled or heated, and is sent from the air-conditioning outlets 41a to 41d through the outlet chambers 4a and 4b and the ducts in this order. Be blown into the room.

  When cooled by the heat exchangers 10a and 10b, the drain generated by condensation of the indoor air humidity drops on the surface of the heat exchanger and accumulates in the drain pans 16a and 16b, and is pumped up by the drain pumps 13a and 13b. It is discharged out of the machine from the pipes 14a, 14b.

  The heat exchanging ventilator 44 is designed to ensure the minimum ventilation amount stipulated by the Building Standards Act, and from the ventilation exhaust suction port 40 through each room for one floor to a slit provided in the lower part of the door. The room air is taken in, exchanges heat with the outside air inside the heat exchange type ventilator 44, becomes a temperature (and humidity) approaching the outside air temperature (and humidity), and is discharged from the exhaust port 43.

  On the other hand, the outside air taken in from the air supply port 42 passes through a filter, an air purifier, etc. inside the heat exchange type ventilator 44, and removes dust, dust, pollen, fine particles (carbon, etc.), odors, harmful gases such as NOx, etc. After being removed and cleaned, the heat is exchanged with the exhaust from the room, the temperature (and humidity) approaches the room air temperature (and humidity), and the air is supplied to the suction chamber 2. This fresh outside air is taken into the indoor units 1a and 1b and distributed to each room.

  The operation state of the indoor units 1a and 1b can be individually controlled by a wireless remote controller, and information such as an operation mode (cooling, heating, dehumidification, ventilation, and stop), a wind speed, and a set temperature set by the user using the remote control is infrared. It is transmitted as a signal, received by the light receiving portions 18a and 18b, and sent to the indoor unit control devices housed in the respective electrical component boxes 15a and 15b.

  Since the light receiving units 18a and 18b are installed close to the suction panel 30, the indoor units 1a and 1b can simultaneously receive signals from one remote controller as the same information. As if it operates as a single indoor unit, a uniform air-conditioned space on one floor can be realized.

  An air conditioning system having the same configuration is also installed on the second floor, and the operation of each indoor unit (a total of four in the case of a two-story building) can be controlled by a wired centralized controller 19. ing.

  The centralized controller 19 can at least operate and stop each indoor unit and simultaneously stop all indoor units. However, in this embodiment, since the supply air of 24 hours constant ventilation is taken into the suction side of each indoor unit, even if the command from the centralized controller stops air conditioning, the air blowing of each indoor unit does not stop. Continue light breeze operation to ensure the ventilation rate of 0.5 times / h necessary for regular ventilation. When the air-conditioning stop is instructed by the wireless remote controller, the blowing is also stopped.

  Since the centralized controller 19 can select the operation / stop (breeze blowing) of each indoor unit (up to four units in a 2-story building), it is possible to perform air conditioning by zone in which one floor is divided into two zones. At this time, by setting the light receiving portion of the signal from the wireless remote controller of each indoor unit apart from each other, the set temperature, the air volume, etc. can be individually set to each indoor unit from the wireless remote controller.

  In this way, for example, the southern zone with a relatively large cooling load in summer can be set to a lower setting temperature, and the north zone with a relatively small cooling load can be set to a higher setting temperature. However, comfort can be improved with an appropriate temperature setting for each zone. In particular, it is possible to obtain a space in which the feeling of comfort is uniform in consideration of radiation from the wall surface and floor surface.

  1 to 5, indoor units 1a and 1b have indoor unit main body inlets 6a and 6b on the back and bottom surfaces, and are installed in the corridor so that the vertical surfaces on the back face each other. Although it is connected by the suction chamber 2 in the vertical surface of the machine body suction ports 6a and 6b, the present invention includes a form in which the suction chamber 2 is not used as shown in FIG.

  In the form shown in FIG. 6, the duct constituting the air supply path from the heat exchange type ventilation device 44 is connected to the suction connection portion of the suction panel 30.

  Indoor unit 1a, 1b has indoor unit main body inlet 6a, 6b in the lower surface, and is installed in a corridor so that the vertical surface of a back may face each other at intervals. The indoor unit main body inlets 6a and 6b are not provided on the rear surface.

In the entire building ventilation air conditioning system configured as shown in FIG. 6, the indoor air and the heat exchange type ventilator 44 from the panel suction port 32 of the suction panel 30 are blown by the blowers 12 a and 12 b driven by the blower motors 11 a and 11 b. The mixed air with the outside air supplied to the indoor side of the suction panel 30 is taken in by a duct constituting the air supply path. The mixed air removes impurities such as dust, dust, odor, and gas by the filter 31 and enters the indoor unit main body inlets 6a and 6b. This mixed air is pushed out from the blowers 12a and 12b to the heat exchangers 10a and 10b, where it is cooled or heated, and then goes through the blowout chambers 4a and 4b and the ducts to the air-conditioning blowout openings 41a to 41d. Blown out.
In the heat exchange type ventilation device 44, impurities are removed from the outside air by a filter or the like.

  By configuring in this way, after installing the indoor units 1a and 1b, the air supply duct can be connected to the suction panel 30 from the indoor side without entering the back of the ceiling. The workability is better than the form.
