摘要： An environmentally harmless refrigerant composition for ammonia absorption refrigerators which can dispense with toxic chromate inhibitors used in the prior art. This composition comprises an aqueous solution of ammonia having a predetermined concentration and at least one of nitric salts and nitrous salts and the concentration of the nitric or nitrous salt is selected within such a range as to substantially minimize the corrosion of the iron-based materials used in the refrigerator, whereby the composition exhibits an excellent corrosion-inhibiting effect and an excellent effect of inhibiting the generation of non-condensable gas. When the concentration of the nitric or nitrous salt is 0.01 % by weight or above, the corrosion-inhibiting effect is particularly excellent.

摘要： PROBLEM TO BE SOLVED: To use liquid fuel in place of gas fuel and save a fuel cost without extremely increasing the entire configuration and size of a refrigerating machine by modifying the combustion system device of an air cooled ammonia absorption refrigerating machine.
SOLUTION: A flame is jetted by directing the nozzle of a gun type kerosene burner 8 sideward a generator 1, namely, to the side part of the generator 1 without directing it directly to the generator 1 as shown by an allow D. Generally, fuel oil generates a long and large flame, however, the flame is guided by a flame passage wall 14 and turned in a L-shape to complete a combustion reaction. As a result of the combustion, a produced high temperature combustion gas flow flows while it comes into contact with heat transfer fins 1a forming the heat receiving part of the generator 1 as shown by arrows e to heat them. The L-shaped long and large flame 9L does not reach the heat transfer fins 1a. Thus, there is no possibility that the heat transfer fins 1a are overheated and soot is not stuck to the heat transfer fins 1a to disturb a thermal conduction.

摘要翻译：要解决的问题：通过改变空气冷却氨吸收式制冷机的燃烧系统装置，可以使用液体燃料来代替燃气燃料并节省燃料成本，而不会极大地增加制冷机的整体结构和尺寸。解决方案：通过将喷枪型煤油燃烧器8的喷嘴侧向发电机1，即发电机1的侧部而不将其直接引导到发电机1，如允许D所示，喷射火焰。通常，燃料油产生长而大的火焰，然而，火焰由火焰通道壁14引导并且变成L形以完成燃烧反应。作为燃烧的结果，如箭头e所示，产生的高温燃烧气体流动与形成发电机1的热接收部分的传热翅片1a接触，以加热它们。 L形的长而大的火焰9L没有到达传热翅片1a。因此，传热翅片1a不可能过热，并且烟炱不粘附到传热翅片1a以扰乱热传导。

摘要： An environmentally harmless refrigerant composition for ammonia absorption-refrigerators which can dispense with toxic chromatic inhibitors used in the prior art. This composition comprises an aqueous solution of ammonia having a predetermined concentration and at least one of nitrate and nitrite and the concentration of the nitrate or nitrite is selected within such a range as to substantially minimize the corrosion of the iron-based materials used in the refrigerator, whereby the composition exhibits an excellent corrosion-inhibiting effect and an excellent effect of inhibiting the generation of non-condensable gas. When the concentration of the nitrate or nitrite is 0.01% by weight or above, the corrosion-inhibiting effect is particularly excellent.
