Ammonia absorption cycle in water was invented in the mid of 19th century, the actual industrial revolution in refrigeration. Zudek is studying ammonia absorbers for years. When we entered the market, we found there were just kinds of ammonia machines: the very big ones in big factories and the very small ones for camper refrigerators. To study this issue in detail, we put together a team made by our engineers and we built a prototype that could exploit the chimney flue heat.
Illycaffè roasting can generate heat up to 400 degrees.
Once, this heat used to be dispersed in the air.
We built a system that was able to catch this warm energy and transform it into 95 degrees’ water. This water feeds our ammonia absorber.
The project worked very well, heat at 95 degrees feeds the absorber, that generates cold power at less than 5/6 degrees.
Zudek water and ammonia absorbers reach chilled liquid temperatures which are lower than those with lithium bromide are.
Temperature range goes from +5°C to -60°C, to fulfil every refrigeration need.
