Title:
空冷吸収式冷凍機
Document Type and Number:
Japanese Patent JP7010608
Kind Code:
B2
Abstract:
Provided is an air-cooled absorption-type refrigerator capable of suppressing the thickening of a liquid film on the downstream side of a heat conduction pipe and efficiently discharging non-condensed gas to the outside. The present invention is provided with: an upper header 3a which distributes a refrigerant steam from a regenerator 1; an upper stage air-cooled heat exchanger 3d which is provided below the upper header 3a and performs heat exchange between the refrigerant steam from the upper header 3a and cooled air; a lower stage air-cooled heat exchanger 3e which is provided below the upper stage air-cooled heat exchanger 3d and performs heat exchange between cooled air and the refrigerant steam that has passed through the upper stage air-cooled heat exchanger 3d; a lower header 3c into which the refrigerant condensed in the upper stage air-cooled heat exchanger 3d and the lower stage air-cooled heat exchanger 3e flows; and a receiving tray 3g and a communication pipe 3h which collect the refrigerant condensed in the upper stage air-cooled heat exchanger 3d and allow the refrigerant to flow into the lower header 3c.
