Abstract
【解決手段】ほぼ垂直に設置した複数の伝熱管の外面に溶液を流下し冷媒蒸気を吸収する吸収器を構成し、伝熱管の内面に冷媒を流下させて管外面の吸収熱を奪う蒸発器を構成するとともに、高温蒸発器の冷媒タンクの仕切り高さを低温蒸発器の冷媒タンクの仕切り高さより低くして高温蒸発器の冷媒蒸気の流動抵抗を小さくし、大きな汲み上げ温度差が得られるようにした。
【選択図】図1
Description
さらに、上記の目的を達成するために、本発明においては、低温蒸発器と高温蒸発器の2ヶ所の蒸発器への液冷媒の供給を同一の冷媒ポンプで行うように構成している。また、再生器からの溶液を吸収器へ送る配管に溶液ポンプを設置し、この溶液ポンプの吐出側配管を分岐して、一方は高温吸収へ、他方は低温吸収器へ接続するように構成している。
Claims (6)
