Trigeneration (CCHP – combined cooling, heat and power)

What is trigeneration?

Trigeration is a simultaneous generation of electricity and useful heating and cooling.

CCHP system consists of a conventional cogeneration unit (producing electricity and heat energy) and an absorption chiller. Absorption chiller consumes waste heat from the cogeneration system and generates cold for air conditioning of buildings and process needs.

Trigeneration is:


Absorption chiller’s energy source is heat, not electricity, therefore the trigeneration provides a much lower cost of 1 kW of cooling in comparison with conventional technologies.


Combining a cogeneration system with an absorption chiller allows using of seasonal excess heat for cooling. Thus, taking into account the all-year capacity utilization, the efficiency of cogeneration system in CCHP systems can be significantly increased.


Trigeneration offers the most reliable and cost effective solution for low-emission cooling systems. Moreover, CCHP systems do not contain hazardous and harmful chemical compounds, since water is using as a refrigerant instead of Freon gases and ammonia.
