CONSTITUTION:A CO2 concentration controller with the use of an air separator 4 using a functional film is provided on one side of an air conditioner 1 and an inlet 404, a non-permeation outlet 405, a permeation outlet 406, a pump 6, a fan 5, an exhaust opening 8 and an outlet 104 are provided. Air is allowed to flow in from the inlet 404 with the use of the fan 5 and CO2 easy to permeate a functional film 402 is permeated by pressure difference with the use of a pump 6 through the functional film 402 to exhaust into the outdoor from the exhaust opening 8 through the permeation outlet 406 and the pump 6. On the other hand, N2 and O2 difficult to permeate the functional film 402 is blown from the outlet 104 through the non-permeation outlet 405 with the use of the fan 5.

By providing the separator on the outdoor side, noise on the indoor side can be reduced. Furthermore, by providing the separation means in the wind circuit of the air conditioner, the blower of the Cot concentration control means can be wiped off.

EXAMPLE Hereinafter, an example of the present invention will be described with reference to the drawings. First, a first example of the present invention will be described using an adsorption method with reference to FIGS. 1 and 2. , ■ is the main body of the air conditioner, side A is the air conditioning control unit for controlling indoor temperature, storm, humidity, etc., and side B is the CO2 concentration control unit for controlling the CO2 concentration in the air. , suction ports 101, 103 and outlet ports 102, respectively.
, 104. The air conditioning control section on the A side consists of a heat exchanger, a blower fan, etc. (not shown).

Figure 2 shows a sectional view of the CO2 concentration control section. In the figure, l is the main body, inside which is installed a CO2 adsorbent 2 and a blower fan 3.In the air conditioner with the above structure, its operation will be explained below.Indoor CO2 concentration When the air blower fan 3 of the CO2 concentration control unit is operated when the temperature exceeds a certain level, air is sucked in from the suction port 103, and the C in the incoming air is
O2 fraction is removed by CC) a adsorbent 2 and f1. ．．

By controlling the Cot concentration in the room,
It is possible to maintain a C (h concentration) suitable for the human body and create a comfortable space. First, the principle of air separation using functional membranes will be explained in the third section.
In the figure, 4 indicates an air separator, and the air separator main body 401 is held by a mesh-like holder 40.
3 into a high pressure side space a and a low pressure side space b, and a holder 40
A functional membrane 402 that facilitates the permeation of C02 is attached to the high pressure side of No. 3. Also, in the air separator main body 401 (upper population 40
4. Unpermeated outlet 40 A permeated outlet 406 is provided, and the permeated outlet 406 is connected to the blowing nozzle 7 via the pump 6.

On the other hand, the blower fan 5 is connected to the unpermeated outlet 405 . The operation of the air separator configured as above will be described below. First, air flows in from the inlet 404 by the blower fan 5, and CO2 permeates through the functional membrane 402. The CO2 permeates through the functional membrane 402 due to the pressure difference between the high pressure side space a and the low pressure side space b caused by the pump 6, and passes through the permeation outlet 40.
On the other hand, N2 and C02, which are guided to the blow-off nozzle 7 through the pump 6 but are difficult to permeate through the functional membrane 402, flow out from the non-permeable outlet 405 by the blower fan 5.

Next, an example in which an air separator using the above-mentioned functional membrane is installed in an indoor unit of an air conditioner will be explained using FIG. 4. In the figure, l is the main body of the air conditioner. A heat exchange fan (not shown) is installed for air conditioning. A CO2 concentration control device using an air separator 4 using the functional membrane is provided on one side of the air conditioner. Here, 404 is the inlet, 405 is the unpermeated outlet, 406 is the permeated outlet, 6 is the pump, 5 is the blower fan, 8 is the exhaust n 10
4 is an air outlet.

Regarding the CO2 concentration control device configured as above,
The operation will be explained below. First, air flows in from the population 404 by the blower fan 5, and CO2 permeates through the functional membrane 402. The CO2 permeates through the functional membrane 102 due to the pressure difference caused by the pump 6. Exhaust port 8 via bomb 6
It is exhausted to the outside. On the other hand, N2, which is difficult to permeate through the functional membrane 402, is blown out from the air outlet 104 via the non-permeable outlet 405 by the blowing fan 5. Therefore, it is possible to vary the CO2 concentration in the entire room.
By providing two concentration control devices indoors, the air blowing circuit between the separator 4 and the pump 6 can have a simple structure. Since the separator can be made smaller compared to the adsorption method, etc., the size of the blower can be reduced.Furthermore, a third embodiment of the present invention will be explained with reference to FIG. In the figure, 1 indicates the indoor air conditioner.
9 is an outdoor unit, and the air separator 4 of the outdoor unit 9 is provided with the same configuration as the second embodiment. The outlet of the imitation blower fan 5 and the outlet 104 of the indoor unit l are connected to the hose 10.
The operation of the COa concentration control device configured as described above will be explained below. First, air flows in from the air supply 404 by the blower fan 5, and COa permeates through the functional membrane 402. The COa permeates through the functional membrane 402 due to the pressure difference caused by the pump 6, and is exhausted from the exhaust port 8 via the permeation outlet 40a and the pump 6.

On the other hand, N2 and 02, which are difficult to permeate through the functional membrane 402, are discharged from the air outlet 104 of the indoor unit 1 via the unpermeated outlet 405 and the hose IO by the blower fan 5. Therefore, it is possible to vary the indoor CO2 concentration by sending air with a low concentration of C(h) into the room.
By installing the concentration control device outside, noise can be reduced compared to installing it on the indoor side, where the noise from the pump 6 and the blower fan 5 is not transmitted into the room. Furthermore, a fourth embodiment of the present invention will be described with reference to FIG.

Here, the same parts as those in the previous embodiment are given the same reference numerals and their explanations are omitted. is installed in the wind circuit of the indoor unit 1.The operation of the CO2 concentration control device configured as described above will be explained below.

First, the air separator 4 is activated by the blower fan 12 of the indoor unit 1.
Air flows in from the inlet 404 of the functional membrane 402, and the CO2 that permeates through the functional membrane 402 due to the pressure difference caused by the bomb 6. 1
02 and is sent from the permeation outlet 406 to the pump 6 and from the exhaust port 8 to the outside of the room. On the other hand, N2, 02, which is difficult to permeate through the functional membrane 402, is blown out from the non-permeable outlet 405 and the air outlet 102 by the blowing fan 12. Therefore, the CO2 concentration on the indoor side can be varied in the same way as in the third embodiment. By using the ventilation circuit of the indoor unit, the device can be made smaller {t. Simplification can be achieved. However, in the first embodiment above, other separation methods may be used (℃). A fan capable of obtaining a high static pressure may also be used.
By installing an air separator in the air conditioner to vary the CO2 concentration in the air, it is possible to control air quality as well as air conditioning, creating a more comfortable space that suits human health. By installing an air separator using a membrane on the indoor side, there is no need to use air transport hoses, etc., and the device can be made more compact. The sound of the fan is no longer transmitted into the room, reducing noise inside the room.Furthermore, by installing an air separator in the air circuit of the air conditioner and sharing the blower fan, it is possible to further simplify the equipment.
