How It works

A cogeneration plant can also be used in trigeneration: in this case, part or all of the heat obtained in the form of hot water can be used to cool water that is used as refrigerant in the production process or in the conditioning plants; it is then possible to produce 2 thermal vectors at the same time.
The transformation of heat into refrigerating power is made possible by the use of the absorption refrigeration cycle, the operation of which is based on a concentration cycle and dilution of a solution (usually water and lithium bromide) instead of condensation and evaporation of a fluid as it does in normal refrigerating units.
