In FIG. 1, reference numeral 1 denotes a main body of the indoor unit, and 2 denotes a box disposed on a side portion of the main body 1, and a frame plate 2a is formed so as to partition a central portion. Reference numerals 3 and 4 denote first and second blowers disposed on both sides of the frame plate 2a, 5 an exhaust port formed on the exhaust side of the first blower 3, and 6 an intake side of the second blower 4. And a damper as a flow path forming means for selectively opening and closing the exhaust port 5 and the intake port 6, and 8 is a ventilation unit composed of 2 to 7. , The main unit 1 and an indoor unit 9. A duct 10 has one end connected to the exhaust port 5 and the intake port 6 and the other end open to communicate with the outside through a hole 12 penetrating the side wall 11. , Electric wires and the like are disposed so as to penetrate together, and the remaining space excluding these is used as an air flow passage.

Next, the operation of the air conditioner according to Embodiment 1 configured as described above will be described. First,
When the outdoor air is taken into the room, the damper 7 is moved to the exhaust port 5 side and the intake port 6 is opened by operating an operation mechanism (not shown) as shown in FIGS. When the second blower 4 is operated, the outdoor air flows in the order of the duct 10, the intake port 6, and the second blower 4, and is drawn into the room, as indicated by the white arrow in the drawing. Next, when exhausting the indoor air to the outside, the operating mechanism (not shown) is operated as shown in FIG. 3 and FIG. Move to open the exhaust port 5. Then, when the first blower is operated, the indoor air flows in the order of the first blower 3-the exhaust port 5-the duct 10 and is exhausted to the outside as shown by the black arrow in the figure.

As described above, according to the first embodiment, the first blower 3 communicating with the exhaust port 5 and the duct 10 and the second blower 4 communicating with the intake port 6 with the duct 10 are provided in the box 2. Since the exhaust port 5 and the intake port 6 are selectively opened and closed by the damper 7, the intake and exhaust are performed by using the entire cross-sectional area of the air flow passage in the duct 10. Therefore, ventilation at a stable flow rate can be performed, and the distribution of intake air and exhaust gas can be easily changed by setting the opening and closing time of the damper 7 according to the environment of the room.

Further, since the same flow passage is used for intake and exhaust, the flow passage is divided by a partition plate as in the conventional case, and the intake and exhaust are separated by separate flow passages. Since the cross-sectional area of the flow passage can be largely used by the integral of the cross-section of the plate, ventilation with a large air volume becomes possible. In the flow passage where only a small cross-sectional area in the duct 10 is originally available, the cross-sectional area of the partition plate is at most However, the impact is very large.

In the above construction, the damper 7 is driven by the operating mechanism. However, the damper 7 slides and rotates by receiving the force of the flow of the air to be taken in and exhausted, so that the exhaust port 5 and the intake port 6 are rotated. May be opened and closed. In this case, an operation mechanism for driving the damper 7 is not required, so that the configuration is simplified.

Embodiment 2 FIG. 7 shows a configuration of a ventilation unit of an air conditioner according to Embodiment 2 of the present invention, wherein (A)
Is a cross-sectional view showing the state of air flow during intake,
(B) is a sectional view showing the state of air flow during exhaust. In the figure, the same parts as those in the first embodiment are denoted by the same reference numerals, and description thereof will be omitted. Reference numeral 13 denotes a blower that can switch the direction of the wind by switching the rotation direction as indicated by an arrow in the drawing, 14 denotes a flow passage formed so as to surround the periphery of the blower 13, and 15 denotes one end of the flow passage 14 and a duct. An outdoor ventilation port 16 communicating with 10 and an indoor ventilation port 16 communicating the other end of the flow passage 14 with the room in which the indoor unit is installed.

As described above, according to the second embodiment, the direction of the wind is changed by switching the rotating direction into the duct 10 and the flow passage 14 communicating with the room through the outdoor vent 15 and the indoor vent 16. Since the switchable blower 13 is provided, and the rotation direction of the blower 13 is appropriately switched according to intake and exhaust, the blower 13
7A, air is introduced into the room in the order of duct 10-outdoor ventilation port 15-flow path 14-indoor ventilation port 16 at the time of intake, and exhaust air at the time of exhaust. As shown in FIG. 7 (B), the indoor air can be led out of the room in the order of the indoor ventilation port 16-the flow path 14-the outdoor ventilation port 15-the duct 10, so that the configuration is simplified with few failures. In addition, the size is reduced, and the number of parts is reduced and the cost is reduced.

Embodiment 3 FIG. 8 is a perspective view showing a configuration of a main part of an air conditioner according to Embodiment 3 of the present invention. In the figure, the same parts as those in the first embodiment are denoted by the same reference numerals, and description thereof will be omitted. 17 is the ventilation section 8
Of the indoor air into the main body 1 of the indoor unit, and is formed upstream of the heat exchanger 18 in the flow of the indoor circulating air indicated by the black arrow in the figure.

As described above, according to the third embodiment, the intake port 17 for the outdoor air into the indoor unit is formed on the upstream side of the heat exchanger 18 for the flow of the indoor circulating air. Since the outdoor air is once heat-exchanged in the heat exchanger 18 and brought into the room after reaching an appropriate temperature, it is introduced into the room, thereby preventing the occurrence of room temperature unevenness due to the intake air and enabling a comfortable ventilation operation. In the above-described configuration, the arrangement of the intake port 17 has been described. If the air flow is formed upstream of the heat exchanger 18, the air before the heat exchange is discharged outside the room, so that waste of heat can be reduced and power can be saved.

Embodiment 4 FIG. 9 shows a configuration of a main part of an air conditioner according to Embodiment 4 of the present invention, in which (A) is a cross-sectional view showing the state of air flow during intake,
(B) is a cross-sectional view showing the state of air flow during exhaust, FIG. 10 is a perspective view showing the configuration of the heat storage member in FIG. 9, and FIG. 11 is a perspective view showing a configuration of the heat storage member in FIG. 9 different from that in FIG. FIG. In the figure, the same parts as those in the first embodiment are denoted by the same reference numerals, and description thereof will be omitted. Numeral 19 denotes a heat storage member provided in the duct 10, for example, as shown in FIG. 10, a first member 19a made of an aluminum plate and having a large heat capacity, and a first member 19a.
a is formed in a fin shape by a plurality of aluminum thin members 19b which are erected on the first member a with a predetermined gap therebetween.
9b.

As described above, according to the fourth embodiment, the heat storage member 19 is provided in the duct 10 so that the air to be ventilated flows through the gap between the second members 19b. When the air passes through the heat storage member 19, the air with the higher temperature radiates heat to the heat storage member 19, and the air with the lower temperature receives heat from the heat storage member 19. Therefore, outdoor air having a high temperature in summer is radiated to the heat storage member 19 to be cooled and then taken into the room, and outdoor air having a low temperature in winter is received by the heat storage member 19 and warmed after being heated. As described above, since the temperature of the intake air can be made close to the room temperature by effectively utilizing the temperature of the exhaust gas, the heat recovery of the ventilation can be achieved with a simple configuration.

Although the case where the heat storage member 19 is disposed in the duct 10 has been described in the configuration in FIG. 9, the heat storage member 19 may be disposed inside the main body 1, and in the configuration in FIG. The case where the heat storage member 19 is formed in a fin shape has been described. However, the present invention is not limited to this. For example, as shown in FIG. 11, a corrugated thin plate material 20a and a flat thin plate material 20b are laminated. A honeycomb-shaped heat storage member 20 may be formed, and needless to say, the same effect as in the case of the heat storage member 19 shown in FIG. 10 can be exerted.

Embodiment 5 FIG. 12 is a sectional view showing a configuration of a main part of an air conditioner according to Embodiment 5 of the present invention. In the figure, the same parts as those in the first embodiment are denoted by the same reference numerals, and description thereof will be omitted. Reference numeral 21 denotes a pair of heat storage members which are configured in the same manner as, for example, the two heat storage members 19, 20 and the like in the fourth embodiment, and are disposed in the main body 1 of the indoor unit and in the duct 10, respectively.

As described above, according to the fifth embodiment, the heat storage members 21 are arranged in the main body 1 of the indoor unit and in the duct 10, respectively, so that the amount of heat recovery is increased and the above-described embodiment is improved. For example, when the heat recovery amount is the same as that in which one heat storage member 19 is arranged as in FIG.
Since the heat storage member 21 is separated into two parts, the volume of the heat storage member 21 can be reduced, and the heat storage member 21 is suitable for being disposed in a narrow space in the duct 10.

Although not shown, the outer surface of the heat storage member 19 along the flow path of the indoor air and the outdoor air is covered with a heat insulating member, so that the heat storage member 19 is surrounded by, for example, the inner wall surface of the duct 10. Since the object is insulated, heat is transferred only to the indoor air and the outdoor air, so that the heat recovery amount can be further increased. The same effect can be obtained by applying to each of the heat storage sections 19 and 20 in the fourth embodiment.

Embodiment 6 FIG. FIG. 13 is a sectional view showing a configuration of a main part of an air conditioner according to Embodiment 6 of the present invention. In the figure, reference numeral 22 denotes a refrigerant pipe 23 in the duct 10.
Is a heat storage member disposed in contact with the heat storage member.

As described above, according to the sixth embodiment, the heat storage member 22 is brought into contact with the refrigerant pipe 23 in the duct 10, so that the temperature of the heat storage member 22 is low in summer and high in winter. Since the air can be taken into the room after the temperature of the outdoor air is adjusted to an appropriate temperature, it is possible to suppress the occurrence of uneven temperature in the room due to ventilation.

Embodiment 7 In the seventh embodiment, although not shown, the surfaces of the heat storage members 19, 20, 21, and 22 in the fourth to sixth embodiments that are in contact with the indoor air and the outdoor air are, for example, silica gel and lithium chloride. It is provided with a member impregnated with a water-absorbing material, a material having a water retaining function by planting a large number of fibrous hairy fibers, and the like.

As described above, according to the seventh embodiment, each of the heat storage members 19, 20, 21, and 22 has a hygroscopic property by mounting a member impregnated with a water absorbing material or a material having a water retaining function. Therefore, at the time of ventilation in summer, for example, the heat storage member 19 adsorbs the moisture of the high-humidity outdoor air that is taken in, and releases the moisture adsorbed by the dried indoor air that is exhausted to the outside. During ventilation in the winter, the heat storage member 19 adsorbs moisture in the exhausted high-humidity indoor air, and collects the moisture adsorbed by the inhaled dry outdoor air in the summer. Intrusion of water can be prevented in winter, and the release of moisture in the room can be prevented in winter, so that total heat recovery is possible and energy saving is achieved. Furthermore, when applied to a structure in which a pair of heat storage members are provided as in the fifth embodiment, it is possible to suppress the invasion of humidity into the duct in both the intake and exhaust.

Embodiment 8 FIG. FIG. 14 is a curve diagram showing a temperature relationship between a heat storage member and air during ventilation of an air conditioner in winter in Embodiment 8 of the present invention.
Is the temperature of the heat storage member, and B is the temperature of the outdoor air and the indoor air to be sucked and exhausted, which is measured at a position after passing through the heat storage member. As shown in the figure, for example, in the case of intake,
The drawn-in outdoor air is warmed by passing through the heat storage member, but cools with the lapse of time as the temperature of the heat storage member decreases. On the other hand, when the exhaust is switched,
The exhausted air in the room is cooled by passing through the heat storage member, but is warmed as the temperature of the heat storage member rises with time.

That is, since the intake and exhaust operations are repeated and heat is stored in the heat storage member as described above, the transfer of heat is not proportional to the time of a single intake or exhaust, and if the heat constant exceeds the time constant, the heat is transferred. Transfer is reduced. Therefore, by setting the time constant of the change in the temperature of the heat storage member to be substantially equal to the time for switching between the exhaust and the exhaust, heat can be efficiently recovered.

Embodiment 9 FIG. 15 is a sectional view showing a configuration of a main part of an air conditioner according to Embodiment 9 of the present invention. In the figure, the same parts as those in the fourth embodiment are denoted by the same reference numerals, and the description is omitted. 24 is antibacterial,
A duct 25 made of a resin containing an anti-mold material is a filter disposed at the outdoor end of the duct 24.

As described above, according to the ninth embodiment, since the duct 24 is formed of a resin containing an antibacterial and antifungal material, the duct 24 itself is prevented from being contaminated, and the outside air to be sucked in is prevented. Since the contamination can be suppressed and the filter 25 is disposed at the outdoor end of the duct 24,
At the time of inhalation, bad odor, dust, pollen, virus, black smoke in exhaust gas and the like contained in the outdoor air are prevented from entering the duct 24 and being taken into the room, thereby enabling clean ventilation.

Although not described in each of the above embodiments, if the exhaust operation is performed for a predetermined time after the end of the cooling and heating, the moisture remaining in the duct can be discharged to the outdoor together with the exhaust air, thereby providing a comfortable environment. Ventilation becomes possible.
