摘要： An absorption type refrigerating machine comprising an evaporator, an absorber, a regenerator, and a condenser, all connected by piping to form a refrigerating cycle. The evaporator, condenser or absorber includes a plurality of heat transmission pipes accommodated therein and arranged generally in a horizontal direction. Each pipe has at least one continuity of protrusion on the inner surface thereof extending in an axial direction of the pipe in a spiral fashion and at least one continuity of groove corresponding to the continuity of protrusion formed on the outer surface of the pipe.

摘要： In a high-temperature regenerator which has vertical liquid pipe groups in the proximity of which a combustion flame and combustion gas from a burner pass and a double can wall which communicates with upper and lower portions of liquid pipes forming the vertical liquid pipe groups and is arranged at a position of a furnace wall and which heats and concentrates a diluted absorption solution passing through the vertical liquid pipe groups and the double can wall, a solution inlet for sprinkling the diluted absorption solution in an open state is provided above liquid pipes arranged on a side opposite to the burner. Since the sprinkled diluted absorption solution collects the heat of an exhaust gas while it falls to increase its temperature, when it flows into the other liquid pipes, it boils immediately and its circulation flow is activated by boiling. Therefore, total heat transfer coefficient can be increased, a local rise in the temperature of the liquid pipe groups and the can wall can be avoided, and such inconvenience as a corrosion accident and the crystallization of a solution caused by this rise in temperature can be prevented.

摘要翻译： 在具有垂直液体管组的高温再生器中，燃烧火焰和来自燃烧器的燃烧气体通过，双壁壁与液体管的上部和下部形成垂直的液体管组，并且是 布置在炉壁的位置，并对通过垂直液体管道组和双壁壁的稀释的吸收溶液进行加热和浓缩，在设置在液体管上方的液体管上方设置有用于将稀释的吸收溶液喷射到打开状态的溶液入口 与燃烧器相对的一侧。 由于喷洒的稀释吸收溶液在下降时收集排气的热量以增加其温度，所以当其流入其它液体管道时，它立即沸腾，并且其循环流动通过沸腾而活化。 因此，可以提高总传热系数，可以避免液管组和罐壁温度的局部升高，并且由于这种温度升高引起的腐蚀事故和溶液的结晶等不便可以 防止了
