Trigeneration in a single process produces three forms of energy: electricity, heating and cooling. Thus, it provides by a single system: energy, hot water, space heating and air conditioning. The combined production of energy as in cogeneration can be successfully applied both in industry and self-consumption purposes.

Trigeneration is not a new concept. This arose from the cogeneration system as an extension of it. Over time trigeneration was encountered in systems upgraded of decentralized energy networks in many European cities, including Berlin, Copenhagen, Stockholm, Helsinki, Vienna, Hamburg, Gothenburg, Paris, Moscow, St. Petersburg, Turin, Barcelona and London.

Both cogeneration and trigeneration is increasingly one of the strategic choices of companies that perceive energy efficiency as a key opportunity to reduce production costs and increase competitiveness.

A trigeneration plant consists of:

A cogeneration plant;

A chiller of absorption compatible with thermal parameters of the cogeneration plant;

A general control panel, equipped with the processor;

Generators lose heat while they create electricity. A trigeneration plant captures that heat that in a conventional system would be lost and uses it to generate both hot and cold water.

Chilled water is created by an absorption chiller, which is generated by the excessof heat and that works as a refrigerator. It creates water at sufficiently low temperature to be used for air conditioning.
