RETROSPECT | A SMALL MACHINE FOR MANY APPLICATIONS (100-300W)

 

- an ammonia water diffusion absorption machine without moving parts and without electricity. The innovation was the bypass. Contrary to the classical absorption refrigerator we use vertical pipes for this machine. The liquid flows in a thin coating along the whole inner side of the pipe and the gas passes through its centre. With such a machine we have obtained a temperature of -30C. But the obtained output power was very small in proportion to the size.
