Description

  The present invention relates to an air conditioner, and more particularly to a structure in which a plurality of rooms having different temperatures can be effectively ventilated by one heat exchange unit without being affected by room temperature.

  As a conventional air conditioner, by setting the ventilation capacity according to the size and usage conditions of each room and freely changing it to the desired ventilation volume, the indoor environment can always be maintained comfortable and the ventilation system is installed There has been disclosed a residential heat exchange type ventilator that increases the degree of freedom of planning and is optimal for a highly airtight and highly insulated house such as a highly airtight and highly insulated house (see, for example, Patent Document 1).

  By combining the heat exchange unit and the air supply unit for each air supply terminal, it has become possible to finely adjust the air volume for each air outlet, which has not been considered in the past in residential ventilation systems. In addition, rapid limited ventilation such as when smoking is possible and priority ventilation when multiple people are in the room is possible, and the supply air volume can be adjusted individually, leading to improved comfort and reduced load on the air conditioner For example, when it is near the air supply outlet, it may feel hot / cold, but it can be improved by changing to a preferred air volume and direction.

  However, when a plurality of rooms having different room temperatures are exchanged and ventilated, for example, as an air conditioner for a building, heat exchange and ventilation can be performed by one heat exchange unit without being affected by different room temperatures. Since each room is supplied with the same temperature, the air conditioning load in each room cannot be reduced optimally. It had the problem that it would end up being supplied.

  Therefore, when a plurality of rooms having different room temperatures are subjected to heat exchange and ventilation, as shown in FIGS. 3 and 5, for example, one room A whose room temperature is adjusted to 25 ° C. and another room whose room temperature is adjusted to 5 ° C. B, a heat exchange unit 4 including a total heat exchange element 1, an air supply fan 2 and an exhaust fan 3, an intake path 5 for sucking outside air as indicated by an arrow a, and air that has been sucked and heat-exchanged As shown by an arrow b, a supply path 6 for supplying a plurality of rooms A and B to a plurality of rooms A and B, a discharge path 8 for discharging air from the plurality of rooms A and B as shown by an arrow c, and a discharged heat An air conditioner having an exhaust path including an exhaust path 9 for exhausting the exchanged air to the outside as indicated by an arrow d is installed.

  However, in this case, since the heat exchange unit 4 is installed according to the number of rooms, the cost due to the initial investment is increased, and the heat exchange unit 4 is provided with ventilation. 4 ducts (intake path 5, supply path 6, discharge path 8 and exhaust path 9) are necessary, and the arrangement and space of the duct on the back of the ceiling can be restricted, and the heat exchange unit 4 Since at least two holes for air supply and exhaust must be penetrated through the wall with respect to the stand, there is a problem that the work becomes large.

  Therefore, as shown in FIGS. 4 and 5, the heat exchange unit 4 including the total heat exchange element 1, the air supply fan 2, and the exhaust fan 3 has an intake passage 5 for sucking outside air, and an intake heat exchange. Air supply path 6 comprising a supply path 6 for supplying the divided air into a plurality of rooms A and B, for example, one room A whose room temperature is adjusted to 25 ° C. and another room whose room temperature is adjusted to 5 ° C. An air conditioner provided with a discharge path 8 that branches off from B and discharges air and an exhaust path that includes a discharge path 9 that discharges the discharged and heat-exchanged air to the outside of the room is installed.

  In this case, since the heat exchange unit 4 is not installed in accordance with the number of rooms, the cost of initial investment is reduced, and the work is not overwhelmed. Thus, air at 25 ° C. from one room A and air at 5 ° C. from the other room B are discharged and mixed to form air of about 15 ° C. and flow into the heat exchanging unit 4 while the heat exchange. After the outside air at 0 ° C. flows into the unit 4 and exchanges heat with the air at about 15 ° C., the air is sucked into the room A at room temperature 25 ° C. and the other room B at room temperature 5 ° C., and is exchanged for about 10.5. The air in the one room A and the other room B, which has been supplied by the supply path 6 as shown by the arrow b and discharged and heat-exchanged to about 4.5 ° C. as indicated by the arrow b, is converted into the air as indicated by the arrow d. Exhaust air is exhausted out of the room by the exhaust passage 9.

  At this time, the outside air that has been heat-exchanged to about 10.5 ° C. is supplied to one room A at room temperature 25 ° C. and another room B at room temperature 5 ° C. In this case, one room having a different room temperature. Supplying the outside air heat-exchanged to A and the other room B at the same temperature does not reduce the air-conditioning load in each room optimally as described above, and depending on the room, it is sometimes uncomfortable. It had the problem that it would supply at a certain temperature.

JP-A-8-178386 (pages 1 to 6 and FIGS. 1 to 2)

  In view of the above problems, an object of the present invention is to provide an air conditioner capable of effectively ventilating with a single heat exchange unit without being affected by room temperature in a plurality of rooms having different temperatures. To do.

In order to solve the above-described problems, the present invention provides a heat exchange unit including a total heat exchange element, an air supply fan, and an exhaust fan with an intake path for sucking outside air and air that has been sucked and heat-exchanged in a plurality of rooms. Connecting an air supply path consisting of a supply path branched and supplied to an exhaust path consisting of an exhaust path for exhausting the heat exhausted from the exhaust path branched for each of the plurality of rooms to the outside,
The heat exchanging unit is partitioned by a first heat insulating partition into a supply passage connecting from the intake passage to the supply passage and an exhaust passage connecting from the discharge passage to the exhaust passage, and a second heat insulating partition. Thus, the supply passage and the exhaust passage are partitioned so as to correspond to the branched supply passage.

  Further, the second heat insulating compartment is configured to be movable along the total heat exchange element.

  According to the present invention, in a plurality of rooms having different temperatures, ventilation can be effectively performed by one heat exchange unit without being affected by room temperature, so that the cost due to initial investment can be suppressed. Therefore, the air conditioner can be simplified so that the work does not become large.

Embodiments of the present invention will be described below in detail as examples based on the accompanying drawings.
FIG. 1 is a perspective view showing an air conditioner according to the present invention, and FIG. 2 is a perspective view of a main part of the air conditioner according to the present invention.

  As shown in FIG. 1 and FIG. 2 as an embodiment 1, the air conditioner according to the present invention has a single heat exchange unit 4 provided with a total heat exchange element 1, an air supply fan 2, and an exhaust fan 3, respectively. And the supply of air that has been sucked and heat-exchanged by the heat exchange unit 4 is branched and supplied to a plurality of rooms A and B having different room temperatures as indicated by an arrow b. Air that has been exhausted as indicated by an arrow c from an air supply path 7 composed of a path 6 and a discharge path 8 branched for each of the plurality of rooms A and B is heat-exchanged by the heat exchange unit 4 toward the outside. It has a configuration in which an exhaust path 10 consisting of an exhaust path 9 for exhausting is connected as indicated by d.

  The one heat exchanging unit 4 includes the total heat exchanging element 1, the air supply fan 2, and the exhaust fan 3, and is configured by connecting the air supply path 7 and the exhaust path 10. Ventilation can be performed while suppressing temperature changes in one room A and the other room B having different room temperatures.

  The heat exchange unit 4 has a total heat exchange from the intake passage 5 by means of a first heat insulating compartment 11 that divides the air passage upward and downward as indicated by solid arrows in FIG. An air supply passage 12 that circulates through the element 1 and continues to the branched supply passage 6 and a branch passage 8 that circulates the total heat exchange element 1 from the branched exhaust passage 8 and continues to the exhaust passage 9. Heat exchange is performed between the outside air and the room air that are partitioned (up and down) into the exhaust passage 13 and flow through the air flow paths of the total heat exchange elements 1 adjacent to each other.

  The air passage in the heat exchange unit 4 is divided into the air supply passage and the exhaust passage by a second heat insulating compartment 14 that further divides the air passage (divided vertically) into left and right. One of the supply passages 6 circulates from the intake passage 5 through the supply passage 12 so as to correspond to the supply passage 6, and then flows through a partial region of the total heat exchange element 1 and continues to the one chamber A. And the other passes through the air supply passage 12 from the intake passage 5 and then passes through the remaining area of the total heat exchange element 1 and communicates with the supply passage 6 connected to the other chamber B. It is partitioned.

  At that time, a portion of the total heat exchange element 1 communicating with the one chamber A is partitioned by the second heat insulating partition 14 so as to be wide with respect to the remaining region. The amount of air in the air supply passage 12 communicating with A is larger than the amount of air in the air supply passage 12 communicating with the other chamber B.

  As a result, by exchanging heat between supply and exhaust, it is possible to supply outside air that has as little temperature difference as possible from the room temperature, thereby reducing air conditioning loss and reducing the air conditioning load in the room. In some cases, supply at an unpleasant temperature is no longer necessary, and the provision of the one heat exchange unit 4 reduces the cost of initial investment and does not require a large amount of work. Thus, the air-conditioning apparatus having a simplified configuration can be provided, and corresponding to the room A and the other room B having different room temperatures, the comfortable ventilation can be performed while suppressing the temperature change of the room A and the other room B. Become.

  Next, as shown in the figure, when the second heat insulating compartment 14 is installed in the approximate center of the total heat exchange element 1 by the air conditioner having the above configuration, the one heat exchange unit 4 supplies and exhausts air. The heat exchange performed between the two will be described.

  For example, when the room A has a room temperature of 25 ° C. and the other room B has a room temperature of 5 ° C. and the outside air temperature is 0 ° C., a part of the 0 ° C. outside air sucked from the intake passage 5 is The heat exchange unit 4 exchanges heat with the 25 ° C. air discharged through the discharge passage 8 communicating with the one chamber A, and the temperature is raised to about 17.5 ° C. to communicate with the one chamber A. Supplied by the air supply passage 12.

  On the other hand, the remaining outside air of 0 ° C. sucked from the intake passage 5 is heat-exchanged by the heat exchange unit 4 with the air of 5 ° C. exhausted through the exhaust passage 8 communicating with the other chamber B, and about The temperature is raised to a temperature of 3.5 ° C., and the air supply passage 12 communicates with the other chamber B.

  The 25 ° C. air discharged from the one chamber A and the 5 ° C. air discharged from the other chamber B were mixed and heat-exchanged with the outside air of 0 ° C. to reach about 7.5 ° C. The exhaust passage 13 communicated with the exhaust passage 9 is exhausted.

  As a result, the one room A is supplied with the outside air raised from 0 ° C. to about 17.5 ° C. with respect to the room temperature of 25 ° C., and the other room B is brought to the room temperature of 5 ° C. On the other hand, outside air having been subjected to heat exchange at about 3.5 ° C. is supplied, and the one heat exchange unit 4 allows the one room A and the other room B to be simultaneously not affected by room temperature. It becomes possible to ventilate comfortably.

  The second heat insulating compartment 14 is not installed at the approximate center of the total heat exchange element 1, but corresponds to the size of the one room A and the other room B, for example, a room on the wide side. The air supply passage 12 that communicates with the air supply passage 12 may be installed at a position where it can be widely secured.

  At that time, a gap generated between the second heat insulating partition 14 and the total heat exchange element 1 is sealed by a sealing member, so that the partition effect can be enhanced. The air flowing through the passage 12 and the exhaust passage 13 and the air flowing through the other air supply passage 12 and the exhaust passage 13 are not mixed with each other, and there is no possibility that noise is generated at the location.

  Further, in FIG. 2, the air supply fan 2 and the exhaust fan 3 are arranged one by one on the windward side from the total heat exchange element 1 in the air supply passage and one on the leeward side from the total heat exchange element 1 in the exhaust passage. However, the arrangement of the air supply fan 2 and the exhaust fan 3 is not limited to this.

For example, you may arrange | position to the lee from the said total heat exchange element 1 of the exhaust passage, and the lee of the said total heat exchange element 1 of an exhaust passage, respectively.
In this case, the windward side from the total heat exchange element 1 in the exhaust passage and the leeward side from the total heat exchange element 1 in the air supply passage are partitioned by the second heat insulating partition 14, so a fan is provided for each partition. In the case of FIG. 2, four fans are required. By arranging in this way, it becomes possible to individually set the air flow rate as appropriate.

Next, as Example 2, a configuration in which the second heat insulating compartment 14 is movable along the total heat exchange element 1 as indicated by an arrow e or an arrow f shown in FIG.
The moving means for moving the second heat insulating compartment 14 is, for example, a linkage mechanism comprising a rack 15 provided integrally with the second heat insulating compartment 14 and a pinion 16 that meshes with the rack 15. And a drive device including a drive motor 17 linked to the linkage mechanism.

  When the volume of the one chamber A having a room temperature of 25 ° C. is large and the volume of the other chamber B having a room temperature of 5 ° C. is small, the second heat insulating partition 14 is moved, for example, the one chamber A The supply passage 12 and the exhaust passage 13 communicating with each other may be secured larger than the volume of the supply passage 12 and the exhaust passage 13 communicating with the other chamber B.

  As a result, the heat exchange region communicating with the other chamber B is expanded with the supply passage 12 and the exhaust passage 13 communicating with the one chamber A, as well as the heat exchange region of the total heat exchange element 1 communicating with these passages. A large amount of outside air heat-exchanged in a heat exchange area larger than the area can be stably supplied to the room A, and the air-conditioning load for each room can be reduced.

  In addition, the heat exchange unit 4 that is the minimum necessary without lineup of various types of the heat exchange units 4 having different dimensions and capacities corresponding to the one room A and the other room B having different room temperatures and volumes. It becomes possible to correspond to various ventilation designs.
