Description

  The present invention relates to an air conditioner, and more specifically, in a plurality of rooms having different temperatures, a plurality of intake passages and exhaust passages connected to one heat exchange unit are provided in these intake passages and exhaust passages. The present invention relates to a structure that can be effectively ventilated without being affected by room temperature by opening and closing with an opening / closing means or switching with a switching means.

  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, and priority ventilation when a large number of people are in the room are 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 be air supply.

  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, an intake passage 5 for introducing outside air to the heat exchange unit 4 including the total heat exchange element 1, an air supply fan 2 and an exhaust fan 3 as shown by an arrow a, and air that has been introduced 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 / exhaust must be penetrated through the wall with respect to the base, 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 from a supply path 6 for supplying the supplied air to a plurality of rooms A and B, for example, one room A whose room temperature is adjusted to 25 ° C. and another room B whose room temperature is adjusted to 5 ° C. An air conditioner provided with an exhaust path 8 for exhausting air and an exhaust path including an exhaust path 9 for exhausting the exhausted 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. As described above, air at 25 ° C. from one chamber A and air at 5 ° C. from the other chamber B are discharged and mixed to form 15 ° C. air and flow into the heat exchange unit 4. After the outside air at 0 ° C. flows into 4 and exchanges heat with the air at 15 ° C., it is sucked into the room A at room temperature 25 ° C. and the other room B at room temperature 5 ° C. and heat exchanged to 10.5 ° C. The outside air is supplied through the supply passage 6 as indicated by an arrow b, and is discharged and heat-exchanged to reach 4.5 ° C. The air in one chamber A and the other chamber B is sent through the exhaust passage 9 as indicated by an arrow d. Exhausted outside the room.

  At this time, the outside air that has been heat-exchanged to 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 A having a different room temperature. As described above, the air conditioning load in each room cannot be optimally reduced by supplying the outside air heat-exchanged to the same temperature with respect to the other room B, and depending on the room, it is sometimes uncomfortable. There was a problem that it would be supplied at a temperature.
