An absorption chiller in the trigeneration plant of a hospital

In a hospital in Verona, the BROAD absorption chiller is a key component of the trigeneration plant, which produces electricity, heat and cooling. The plant supplies 7 bar(g) steam for both the absorption chiller and the hospital utilities.

In Italy, hospitals pay a fixed charge based on their contracted electrical capacity, and exceeding it leads to penalties. Driven by steam, the absorption chiller covers peak cooling demand without increasing electricity consumption.
