るものである。 Such an air conditioning ventilation fan 1 turns on exhaust and intake fans 4 and 5 to generate airflow in both passages 2 and 3, thereby guiding indoor air to the outdoors and outdoor air to the indoor room. It removes pollutants such as CO, CO 2 , dust, and moisture from indoor air, and at the same time, during heating operation, fresh outdoor air is exchanged with the exhausted indoor air to be used as relatively warm air that is later returned indoors. It is something that is discharged to.
〈考案が解決しようとする問題点〉
ところで、特に寒冷地域で冬期にこの種の空調
換気扇１を使用すると、室内空気と室外空気との
温度差により、高温側の室内空気が流通する熱交

付着した結露水が霜となり、着霜量の増大にとも
なう熱交換効率の低下、及び熱交換器６の流通面
積の減少による換気性能の低下を招いてしまう。<Problems to be solved by the invention> By the way, when this type of air conditioning ventilation fan 1 is used in winter in particularly cold regions, due to the temperature difference between indoor air and outdoor air, a heat exchanger through which indoor air on the high temperature side flows Condensation occurs on the inner wall of the indoor air exhaust passage 2 at No. 6. If this condensed water is not drained outside immediately,
The attached dew condensation water becomes frost, resulting in a decrease in heat exchange efficiency due to an increase in the amount of frost formation, and a decrease in ventilation performance due to a decrease in the flow area of the heat exchanger 6.
このため、上記従来装置のように、結露水を排
気流中に晒したまま外部に排出するようにして、
排気熱及び凝縮熱を利用して結露水の凍結防止を
図りつつこれを行うような構成とすることが好ま
しい。 For this reason, as in the conventional device described above, the condensed water is discharged outside while being exposed to the exhaust flow.
It is preferable to use exhaust heat and condensation heat to prevent condensed water from freezing.

音が大きい）をできるだけ抑える対策が必要とな
るが、特別に両フアン４，５を覆う防音構造を設
けると圧力損失が大きくなる。 However, if the exhaust fan 4 is disposed at the outdoor end of the indoor air exhaust passage 2, that is, on the downstream side of the exhaust from the heat exchanger 6, the waste water will be blown away from the open end of the exhaust passage 2. As shown in the figure, the exhaust fan 4 has to be installed at the indoor end of the indoor air exhaust passage 2, that is, on the upstream side (indoor side) of the heat exchanger 6. , the intake fan 5 will also be arranged on the indoor side. For this reason,
It is necessary to take measures to suppress as much as possible the noise propagating into the room from the exhaust fan 4 and intake fan 5 (the latter is particularly noisy because it discharges air into the room). If this is provided, the pressure loss will increase.
本考案はこのような従来の実情に着目してなさ

This effectively reduces the noise propagating into the fan's room while increasing the intake air temperature.
〈実施例〉
以下、本考案の実施例を第１図及び第２図に基

後に天井内に吐出される。 During normal ventilation operation, the air conditioning ventilation fan 11 with such a configuration maintains the exhaust fan 4, the intake fan 5, and the circulating air fan 9 in the ON state, and supplies air into the indoor air exhaust passage 2, the outdoor air intake passage 3, and the circulation passage 7. The so-called ventilation operation is continued by generating airflow in each case. Therefore, in this case, indoor air passes through the indoor air exhaust passage 2, passes through the heat exchanger 8A, exhaust fan 4, and heat exchanger 6 in order and is exhausted to the outdoors, and outdoor air passes through the outdoor air suction passage 3 and passes through the heat exchanger 8A, and the heat exchanger 6. 6. The air passes through the intake fan 5 and the heat exchanger 8B in this order, exchanging heat with the indoor air at the heat exchanger 6, and exchanging heat with the air in the ceiling at the heat exchanger 8B, before being discharged into the room. On the other hand, the air in the ceiling flowing through the circulation passage 7 passes through the circulation air fan 9 and then passes through the heat exchanger 8.
A and 8B, the air exchanges heat with the indoor air in the indoor air exhaust passage 2 and the outdoor air in the outdoor air suction passage 3, and is then discharged into the ceiling.

生じ室内に伝わる騒音は、該両フアン４，５より

て遮音されるので、大幅に低減でき、騒音防止効
果が高まる。 At this time, the noise generated by the exhaust and intake fans 4 and 5 and transmitted into the room is largely insulated by the heat exchangers 8A and 8B, which are placed closer to the room than the fans 4 and 5. It can reduce noise and increase the noise prevention effect.

もに、吸入通路３を形成する配管の温度も高めら
れて配管結露を可及的に防止できる。 In addition, since the air flowing through the heat exchangers 8A and 8B on the indoor side is the air in the ceiling, especially when used in winter in cold regions, the heat in the ceiling that is kept at a relatively high temperature is wasted. By being available, the outdoor air, which has been heated by exchanging heat with the indoor air in the heat exchanger 6, can be further heated by exchanging heat with the heat exchanger 8B, thereby further increasing the temperature of the supply air supplied indoors. This makes it difficult to feel cold air indoors, and the temperature of the piping forming the suction passage 3 is also increased, making it possible to prevent piping condensation as much as possible.
尚、循環空気フアン９をオフとしても、排気及
び吸気フアン４，５の騒音防止効果を充分に得ら
れることは勿論である。 It goes without saying that even if the circulating air fan 9 is turned off, the noise prevention effect of the exhaust and intake fans 4 and 5 can be sufficiently obtained.

の防音効果がより高まることは明らかである。 In addition, the material of the heat exchanger of each of the heat exchangers 6, 8A, and 8B is, for example, the heat exchanger 6, which exchanges heat between indoor air and outdoor air, is made of synthetic resin that is resistant to dew condensation. If the heat exchangers 8A and 8B, through which heat is exchanged between indoor air and outdoor air, are made of washi paper, which has excellent sound absorption properties, both fans 4 and 5 that transmit heat into the room
It is clear that the soundproofing effect of

A circulating air fan 19 is provided between the circulating air fan 19 and the circulating air fan 19. In this way, the transmission of noise caused by the circulating air fan 19 can be prevented not only on the air outlet side but also on the inlet side by the two heat exchangers 18A and 18B. Can be effectively blocked.
