(Example) The air conditioner with oxygen enrichment device shown in FIG. 1 is an integrated air conditioner, which includes an air conditioner body (1),
1) includes an indoor chamber (4) having an indoor suction port (2) and an indoor air outlet (3), and an outdoor chamber (7) having an outdoor suction port (5) and an outdoor air outlet (6). An indoor fan (8) and a user-side heat exchanger (9) are installed in the indoor chamber (4).
The outdoor chamber (7) also includes an outdoor blower (10) that circulates outdoor air from the outdoor suction port (5) to the outdoor air outlet (6), and a heat source that exchanges heat with the outdoor air. and a heat source side heat exchanger (11), the heat source side heat exchanger (11) being disposed in the middle of a distribution path (12) of outdoor air that is circulated by the operation of the outdoor blower (10). There is.

The outdoor chamber (7) houses a compressor (13), and the refrigerant is transferred from the compressor (13) to the heat source side heat exchanger (1).
1) and the utilization side heat exchanger (9).

Then, the outdoor suction port (
5) to the outdoor air outlet (6) is heat-exchanged by the heat source side heat exchanger (11), and the indoor air sucked into the indoor chamber (4) from the indoor suction port (2) is transferred to the user side. Heat is exchanged with a heat exchanger (9), and the indoor air after heat exchange is blown out from an indoor air outlet (3) to air-condition the room.

Note that (14) is a filter.

Therefore, the outdoor chamber (7) is provided with an oxygen enricher (15) consisting of the following configuration, that is, an oxygen enriching membrane (16) that separates the atmosphere into oxygen enriched air and nitrogen enriched air. a separation membrane module (17), a vacuum pump (18), and an oxygen-enriched air supply pipe ( An oxygen enricher (15) consisting of the following components (19) is installed inside the room, and the separation membrane module (17) is placed in the middle of the outdoor air circulation path (12).

Specifically, for example, an oxygen enrichment membrane (16) made of a silicone-based or fluorine-based polymer resin film is pasted on the front and back outer surfaces in the thickness direction of a framework-like frame (not shown) having a predetermined thickness, and a box-shaped frame is formed. A separation membrane module (17) is formed, and one side of the framework-like frame is connected to a secondary space provided inside each of the oxygen enrichment membranes (16) constituting the separation membrane module (17). An outlet (20) for oxygen-enriched air is provided. The separation membrane module (17) formed in this way is placed in parallel at intervals in a rectangular cylindrical module case (21) that is open at both ends and has a rectangular cross section, as shown in Figure 2. The oxygen enrichment membrane (16) is supplied with outdoor air from one side of the open side of the case (21).
) to separate outdoor air into oxygen-enriched air and nitrogen-enriched air.

An oxygen-enriched air supply pipe (19) (hereinafter referred to as the supply pipe) is connected to the outlet (20), and the vacuum pump (18) is installed in this supply pipe (19). That's what I do. The suction side of the vacuum pump (18) communicates with the outlet (20), and the suction side of the vacuum pump (18) communicates with the outlet (20).
18), the pressure on the secondary side of the oxygen enrichment membrane (16) is lower than that on the primary side to create a pressure difference between the primary side and the secondary side, and the separation membrane module (17) is installed inside the membrane. The outdoor air supplied into the case (21) is separated into oxygen-enriched air and nitrogen-enriched air.

Then, as shown in FIG. 1, the module case (21) containing a large number of the separation membrane modules (17) is placed immediately in front of the air inlet side of the heat source side heat exchanger (11), and the The vacuum pump (18) interposed in the supply pipe (19) is arranged between the outdoor suction port (5) and the outdoor blower (10), and
9) housed in the indoor chamber (4).
The vacuum pump (18) is driven to take out oxygen-enriched air from the secondary side of the oxygen-enriched membrane (16), and this oxygen-enriched air is combined with indoor air to The air is supplied indoors through an indoor air outlet (3).

Therefore, with the above configuration, the compressor (13)
When the indoor and outdoor blowers (8) and (10) are driven, refrigerant is supplied from the compressor (13) to each heat exchanger (9) and (11), and the rotation of the indoor blower (8) causes the indoor Air is passed through the filter (1) from the indoor suction port (2).
4) and is sucked into the indoor chamber (4), passes through the user side heat exchanger (9) and is heat exchanged, and after the heat exchange is blown out indoors from the indoor air outlet (3). As the outdoor blower (10) rotates, outdoor air is sucked into the outdoor chamber (7) from the outdoor suction port (5), cools the vacuum pump (18), and then cools the separation membrane module (1).
After passing through a module case (21) containing a large number of heat exchangers (7), the heat is exchanged with a heat exchanger (11) on the heat source side, and then blown out from the outdoor outlet (6). When outdoor air passes through the case (21), the oxygen enrichment membrane (16) is driven by the vacuum pump (18).
) is lower than the primary pressure, so
Oxygen molecules and water vapor molecules in the outdoor air that pass through the primary side of the oxygen enriched membrane (16) pass through the oxygen enriched membrane (16), and the oxygen enriched membrane (16) passes through the oxygen enriched membrane (16). Oxygen-enriched air is obtained, and this oxygen-enriched air is supplied to the outlet (2).
0) to the indoor blower (8) via the supply pipe (19).
) is supplied to the air outlet side of the room, where it joins with the indoor air that has undergone heat exchange with the user-side heat exchanger (9), and is then supplied into the room from the indoor air outlet (3) to improve the indoor oxygen concentration. .

On the other hand, since the amount of nitrogen molecules passing through the oxygen-enriching membrane (16) is smaller than that of oxygen molecules, nitrogen-enriched air is obtained on the primary side of the oxygen-enriching membrane (16). The outdoor air outlet (6) passes through the heat source side heat exchanger (11).
It blows out to the outside.

Further, the vacuum pump (18) is connected to the oxygen enriched membrane (16).
), it generates heat and reaches a high temperature, but as mentioned above, it is cooled by the outdoor air before heat exchange, and even in the summer when the outside temperature is high and air conditioning is required, the temperature remains at 60 degrees Celsius.
Therefore, the performance of the vacuum pump (18) can be prevented from deteriorating.

Further, since the oxygen-enriching membrane (16) has the property of allowing water vapor to pass along with oxygen while not allowing nitrogen and germs to pass through, the humidity of the oxygen-enriched air increases as the nitrogen-enriched air is separated. Therefore, indoor air can be humidified without installing a humidifier, and in winter when the air is particularly dry, there will be no discomfort due to a decrease in the humidity of the indoor air blown into the room. It is hygienic because there is no contamination of bacteria and clean air can be supplied indoors.

Therefore, according to the air conditioner with oxygen enrichment device described above, the module case (21) is placed in the middle of the outdoor air distribution path (12) in the outdoor room (7),
The supply pipe (19) interposed with the vacuum pump (18)
Clean, oxygen-enriched air can be continuously supplied to the indoor chamber (4) with a simple configuration in which a This makes it possible to continuously supply oxygen-enriched air into the room without having to worry about it.

Therefore, the oxygen enrichment machine (1
5) can be incorporated into the outdoor room (7), thereby providing an overall compact air conditioner with an oxygen enrichment device.

Further, the vacuum pump (18) can be cooled by the outdoor air before heat exchange with the heat source side heat exchanger (11), and the temperature of the vacuum pump (18) is kept at a constant temperature, for example, 60°C.
This prevents the vacuum pump (18) from deteriorating in performance.

The above description has been about an integrated air conditioner that integrates the indoor chamber (4) and the outdoor chamber (7), but they are of separate type, with an indoor unit (not shown) placed indoors and an outdoor unit placed outdoors. (71) may constitute an air conditioner, and in this case, as shown in FIG. A partition plate (30) is installed inside to partition a distribution route (12) of outdoor air leading to the outlet (6), and an outdoor blower (10) for distributing outdoor air is installed in the center of the distribution route (12). In addition, a vacuum pump (18) and a compressor (13) are installed below the outdoor unit (71). Furthermore, the distribution route (12

In this way, the oxygen-enriched air obtained on the secondary side of the oxygen-enriched membrane (16) can be supplied into the indoor unit via the supply pipe (19) by operating the vacuum pump (18). That's what I do. In addition, in Figure 3,
(31) is the refrigerant discharge pipe, (32) is the refrigerant suction pipe, (
33) is the compressor (13) and the heat source side heat exchanger (11)
The refrigerant discharge pipe (31) sends the refrigerant to the indoor unit, and the refrigerant suction pipe (33) returns the refrigerant to the compressor (13).

Since oxygen-enriched air can be supplied to the indoor chamber (4), the air with oxygen enrichment device has a simple configuration, reduces the number of parts and saves space, and can easily supply oxygen-enriched air without complicated valve operations. Can provide harmonization device.

In addition, since the oxygen-enriching membrane (16) has the property of allowing water vapor to pass along with oxygen but not allowing bacteria to pass through, the humidity of the oxygen-enriched air increases as the nitrogen-enriched air is separated, resulting in humidification.
