図6Aに示すように、上記アクチュエータ30は、本体10の長手方向に延びる細長いホルダ31と、引張コイルスプリングからなる形状記憶合金製のスプリング32(弾性体)と、引張コイルスプリングからなるバイアススプリング33(バイアス弾性体)と、移動カム部材34(移動体)とを備えている。以下、上記形状記憶合金製のスプリング32を簡略化して形状記憶スプリングと称す。 The

上記ホルダ31は、本体10に対して長手方向にスライド可能ではあるが、後述する自動制御モードでは、停止位置に保持されており、移動カム部材34は屋外側の温度環境に応じて両スプリング32,33の弾性力が均衡する位置になるように制御される。
形状記憶スプリング32の温度特性には若干バラツキがあるが、このバラツキは、例えばバイアススプリング33のホルダ31への連結位置を調節することにより補償することができる。その結果、アクチュエータ30は所定の温度特性を得ることができる。 In the present embodiment, the

屋内側の換気装置8Bの温度感応アクチュエータ30は、屋外側の気温、すなわち断熱空間6の気温に応答して作動するが、この断熱空間6の気温は屋外の気温に比べて高い。そのため、屋内側の換気装置8Bの温度感応アクチュエータ30が屋外側の換気装置8Aと同じ温度特性を有していると、屋外側の換気装置8Aより換気通路16の開口面積が大きくなってしまう。しかし、前述したように屋内側の換気装置8Bの温度特性が図7において点線で示すように高温側にシフトしているため、作動板20の開き角度Θの増大を抑制できる。例えば断熱空間6の気温が屋外の気温に比べて5°Cほど高く10°Cであった場合には、図7においてΔΘで示す角度分だけ開きを抑制することができ、換気通路16の開口面積を屋外側の換気装置8Aと同様に最小にすることができる。 When the outdoor air temperature becomes 5 ° C. during cold weather, the opening area of the

In the above embodiment, an elastic body made of a shape memory alloy is used as the temperature sensitive actuator, but a bimetal or the like may be used.
作動板は回動せずに、装置本体の主壁に接し、装置本体の長手方向にスライドすることにより、換気通路の開口面積を調節してもよい。この場合、移動体は作動板の固定位置に連結される。
自動調節モードにおいて、換気通路の開口面積の最小値をゼロにしてもよい。 The forced closing means may be omitted. In this case, the operation plate is rotated only by automatic control, and one end of each of the shape memory spring and the bias spring is fixed to the main body.
The opening area of the ventilation passage may be adjusted by contacting the main wall of the apparatus main body and sliding in the longitudinal direction of the apparatus main body without rotating the operation plate. In this case, the moving body is connected to the fixed position of the operating plate.
In the automatic adjustment mode, the minimum value of the opening area of the ventilation passage may be zero.
