AIR-COOLED ABSORPTION TYPE REFRIGERATOR

To provide an air-cooled absorption type refrigerator that can restrain a liquid film from becoming thicker at a downstream side of a heat transfer pipe, and can efficiently discharge non-condensable gas to the outside.SOLUTION: An air-cooled absorption type refrigerator comprises an upper header 3a for distributing refrigerant vapor from a regenerator 1, an upper air-cooled heat exchanger 3d provided at a lower side of the upper header 3a to exchange heat between the refrigerant vapor from the upper header 3a and cooling air, a lower air-cooled heat exchanger 3e provided at the lower side of the upper air-cooled heat exchanger 3d to exchange heat between the refrigerant vapor passed through the upper air-cooled heat exchanger 3d and the cooling air, a lower header 3c into which the refrigerant condensed in the upper air-cooled heat exchanger 3d and the lower air-cooled heat exchanger 3e flows, and a receiver 3g and a communicating tube 3h for collecting the refrigerant condensed in the upper air-cooled heat exchanger 3d to cause it to flow into the lower header 3c.SELECTED DRAWING: Figure 1 【課題】伝熱管の下流側において液膜が厚くなるのを抑制することができ、不凝縮ガスを効率的に機外に排出可能な空冷吸収式冷凍機を提供する。【解決手段】再生器１からの冷媒蒸気を分配する上部ヘッダ３ａと、上部ヘッダ３ａの下側に設けられ、上部ヘッダ３ａからの冷媒蒸気と冷却空気との間で熱交換を行う上段空冷熱交換器３ｄと、上段空冷熱交換器３ｄの下側に設けられ、上段空冷熱交換器３ｄを通過した冷媒蒸気と冷却空気との間で熱交換を行う下段空冷熱交換器３ｅと、上段空冷熱交換器３ｄおよび下段空冷熱交換器３ｅで凝縮した冷媒が流入する下部ヘッダ３ｃと、上段空冷熱交換器３ｄで凝縮した冷媒をまとめて下部ヘッダ３ｃに流入させる受皿３ｇおよび連通管３ｈとを備える。【選択図】図１
