Description

請求項１の発明は、天井裏に設置するケーシングに還気口を設け、前記ケーシングの側壁に、外気を導入する外気吸入口と、室内の空気を排出する排気口と、前記外気を複数の室内に給気する室内給気口とを配設し、前記ケーシング内に、外気を吸い込むための第１の送風機と、室内からの空気を吸い込んで排出するための第２の送風機と、外気と室内からの空気とを熱交換する熱交換器とを設け、
前記ケーシングは、前記第１の送風機によって前記外気吸入口から導入された外気が、前記還気口から吸い込まれた室内の空気と熱交換器で熱交換された後に、前記室内給気口から複数の室内に給気され、室内の空気が、前記第２の送風機によって前記還気口から取り入れられ、前記外気吸入口から導入した外気と前記熱交換器で熱交換された後に、前記排気口から室外へ排出するよう構成される熱交換型換気装置であって、
前記ケーシングは、天井裏に設置するための開口の一端に取り付けられ且つ前記室内給気口を設けた第１の側板と、前記開口の他端に取り付けられ且つ前記外気吸入口及び排気口を設けた第２の側板と、この第１の側板と第２の側板との間に設置される保持枠体とを備え、
前記保持枠体内に、前記第１の送風機と第２の送風機と熱交換器とを設け、
前記保持枠体を前記第１の側板と第２の側板との間に下側から挿入して取り付けることを特徴とする。 According to the first aspect of the present invention , a return air port is provided in a casing installed on the back of the ceiling, and an outside air intake port for introducing outside air, an exhaust port for discharging indoor air, and a plurality of the outside air are provided on the side wall of the casing. An indoor air supply port for supplying air into the room, a first blower for sucking outside air into the casing, a second blower for sucking and discharging air from the room, and the outside air A heat exchanger for exchanging heat with air from the room,
The casing has a plurality of external air introduced from the outside air inlet by the first blower after heat is exchanged with indoor air sucked from the return air by a heat exchanger. After the indoor air is taken in from the return air port by the second blower and exchanged with the outside air introduced from the outside air intake port by the heat exchanger, A heat exchange type ventilator configured to discharge to the outside,
The casing has a first side plate attached to one end of an opening for installation on the ceiling and provided with the indoor air supply port, and is attached to the other end of the opening and provided with the outside air intake port and the exhaust port. A second side plate, and a holding frame body installed between the first side plate and the second side plate,
In the holding frame body, the first blower, the second blower, and the heat exchanger are provided,
The holding frame is attached by being inserted from below between the first side plate and the second side plate .
