Abstract

冷凍装置３０は、インバータ圧縮機３２Ａを設けた第１冷凍回路３１Ａと、一定速圧縮機３２Ｂを設けた第２冷凍回路３１Ｂとの２系統の独立した冷凍回路を備える一方、蒸発器３７は両冷凍回路３１Ａ，３１Ｂに共用される。通常はインバータ圧縮機３２Ａが駆動され、必要に応じて一定速圧縮機３２Ｂが併せて駆動される。蒸発器３７は、空気流通方向に沿った姿勢で同空気流通方向と交差する方向に間隔を開けて並べられた複数枚のフィン４０からなるフィン群４１を有する。このフィン群４１に対して蒸発管が各フィン４０を空気流通方向に沿ってジグザグ状に蛇行しつつ貫通しかつ上下４段に亘って配管されるが、特に下側の２段に第１冷凍回路３１Ａの第１蒸発管４５Ａが、上側の２段に第２冷凍回路３１Ｂの第２蒸発管４５Ｂがそれぞれ配管される。
