[0045]
FIG. 9 is a schematic configuration diagram of an air conditioner 100 including the indoor unit 10 for air conditioning.
In FIG. 9, reference numeral 30 denotes an outdoor unit for air conditioning. The outdoor unit 30 for air conditioning includes a compressor 31 for compressing the refrigerant, an outdoor heat exchanger 32 for exchanging heat between the refrigerant and the outdoor air, and a refrigerant and the outdoor air in the outdoor heat exchanger 32. And an outdoor fan 33 that promotes heat exchange with the fan.
Reference numeral 50 denotes a refrigerant pipe for connecting the air conditioning indoor unit 10 and the air conditioning outdoor unit 30 and circulating a refrigerant between the air conditioning indoor unit 10 and the air conditioning outdoor unit 30.
Reference numeral 60 denotes a remote controller (remote controller), by which the operating state of the air conditioner 100 can be set.
[0046]
In FIG. 9, reference numeral 70 denotes a ventilation hose, one end of which is connected to the outlet 19b of the ventilator 19 and the other end of which is located outside the room.
As a result, the air that has passed through the ventilation device 19 is discharged outside the room.
[0047]
In the air conditioner 100 including the air conditioning indoor unit 10 configured as described above, the air conditioner 100 is provided in the duct 20 during a heating operation performed to inactivate the allergen captured by the allergen inactivation filter. The damper 24 takes the position shown in FIG. 8A, that is, the position where the first opening 21 is closed, the position where the second opening 22 is communicated with the third opening 23, and the ventilator 19 operates. It is supposed to.
[0048]
Thereby, the warm air around the heat exchanger heated to inactivate the allergen captured by the allergen inactivating filter can be discharged outside the room through the duct 20 and the ventilation device 19, for example, in summer. Even if the air conditioner 100 is set to a heating operation in order to inactivate the allergen captured by the allergen inactivating filter during the cooling of the air conditioner, it is possible to prevent the warm air around the indoor heat exchanger from leaking into the room. be able to.
[0049]
Further, even if the allergen trapped in the filter for inactivating allergen by heating is dropped from the filter, the allergen is reliably discharged to the outside by the duct 20 and the ventilation device 19, so that the allergen is re-exposed. It can be reliably prevented from being returned to the room.
[0050]
On the other hand, in the air conditioner 100 including the air-conditioning indoor unit 10 configured as described above, when performing the ventilation operation of discharging the indoor air to the outside, the damper 24 provided in the duct 20 includes the damper 24 illustrated in FIG. , That is, the position where the communication between the second opening 22 and the third opening 23 is cut off, and the position where the first opening 21 and the third opening 23 are connected, is taken. Is activated.
[0051]
Thereby, the indoor air can be discharged outside the room via the duct 20 and the ventilation device 19. That is, harmful gases such as carbon dioxide generated by human breathing and formaldehyde generated from building materials and wallpaper can be discharged to the outside of the room.
[0052]
As shown in FIG. 1, the allergen deactivation filter 18 is provided near the indoor heat exchanger 13, that is, on the upstream side of the air flow path.
Thus, the condensed water generated in the indoor heat exchanger 13 can efficiently increase the relative humidity of the allergen deactivation filter 18.
Further, the heat of the heated indoor heat exchanger 13 can be efficiently transmitted to the allergen deactivation filter 18.
[0053]
Furthermore, since the second opening 22 of the duct 20 is open toward the upstream side of the air flow path of the indoor heat exchanger 13, the flow of air when heating the allergen inactivating filter 18 is reduced by the indoor heat. The flow goes from the exchanger 13 to the allergen deactivation filter 18, and the allergen deactivation filter 18 can be heated more efficiently.
[0054]
As a recent research result, moisture (moisture) is given to the above-mentioned allergen inactivation filter 18 so that the relative humidity becomes 80% or more, and this allergen inactivation filter 18 is heated at 40 ° C. or more for about 30 minutes. The results show that the inactivation rate of the allergen exceeds 80%.
Therefore, in the allergen removal operation mode, it is most effective if the allergen deactivation filter is operated in such a state in the indoor unit for air conditioning and the air conditioner described above.
[0055]
The allergen removal operation can be operated not only during the cooling operation (or dehumidification operation) in the summer as described above, but also during the heating operation in the winter.
During the winter heating operation, a low-capacity cooling operation is performed to increase the relative humidity of the allergen deactivation filter 18 to, for example, 80% or more. At this time, in order to prevent the cold air around the indoor heat exchanger from leaking into the room, it is preferable that the damper 24 is positioned in FIG. 8A and the ventilator 19 is operated.
After the relative humidity (moisture) required for the enzyme of the filter to exert its effect is ensured by the cooling operation, the indoor heat exchanger is heated again to, for example, 40 ° C. or higher as the heating operation.
Thereby, the allergen captured by the allergen inactivation filter 18 can be inactivated.
[0056]
Further, if this air conditioner 100 is used, it is possible to capture and inactivate indoor allergens even in spring and autumn.
That is, by operating the air conditioner 100 to blow air, allergens present in the room are captured by the allergen inactivation filter 18.
Next, in order to increase the relative humidity of the allergen inactivating filter 18 to, for example, 80% or more, a low capacity cooling operation is performed. At this time, in order to prevent the cold air around the indoor heat exchanger from leaking into the room, it is preferable that the damper 24 is positioned in FIG. 8A and the ventilator 19 is operated.
After the relative humidity (moisture) required for the enzyme of the filter to exert its effect is ensured by the cooling operation, the indoor heat exchanger is heated again to, for example, 40 ° C. or higher as the heating operation. Also in this case, it is preferable that the damper 24 is located in FIG. 8A and the ventilator 19 is operated to prevent the warm air around the indoor heat exchanger from leaking into the room.
Thereby, the allergen captured by the allergen inactivation filter 18 can be inactivated.
[0057]
As described above, by using the indoor unit for air conditioning according to the present invention and the air conditioner equipped with the same, it is possible to remove and inactivate indoor allergens throughout the year and to generate unpleasant air that does not match the season. Can be prevented from being released.
[0058]
Furthermore, in the above-described embodiment, the allergen deactivation filter 18 is disposed only in the indoor heat exchanger 13, but the present invention is not limited to this, and the indoor heat exchanger 14 and / or the indoor heat exchange It can also be arranged upstream of the air flow path of the vessel 15.
[0059]
Furthermore, the duct 20 described with reference to FIGS. 2, 8, and 9 is not limited to this, and the first opening 21 is closed by a wall surface and does not have the damper 24. It may be something. That is, as shown in FIG. 8A, the air having the second opening 22 and the third opening 23, and thereby the air inside the room that has passed through the pre-filter 25 and the air inside the indoor unit 10 for air conditioning. May be formed as a duct in which only the flow path (second discharge path) C <b> 2 leading to the suction port 19 a of the ventilation device 19 is formed. In other words, a duct that opens at a position where the air in the room that has passed through the pre-filter 25 and the air in the indoor unit for air conditioning 10 can be sucked may be arranged at the suction port 19 a of the ventilation device 19.
As described above, the manufacturing cost can be reduced by omitting the first opening 21 and the damper 24.

[0067]
According to the invention as set forth in claim 8, in the allergen removal operation mode, after the appropriate humidity is given to the allergen inactivation filter by the cooling operation, the allergen inactivation filter is heated at the appropriate temperature by the heating operation. Since allergens can be inactivated, allergens in the room can be removed and inactivated throughout the year, and the room can be kept in a clean state in which the allergens are reduced or eliminated at any time.
Also, if there is a possibility that air that does not conform to the indoor conditions in the indoor unit for air conditioning may leak into the room due to cooling operation or heating operation when inactivating the allergen, the air around the indoor heat exchanger is ventilated. Since the air is discharged outside the room by the device, the feeling of the user in the room can always be kept in a comfortable state.
