TRI-GENERATION / COMBINED COOLING HEAT AND POWER (CCHP)

Tri-generation or Combined Cooling, Heat and Power (CCHP) refers to the simultaneous generation of electricity, useful heating and cooling. The process is similar to Co-Generation with the only difference being some of the waste heat produced by the Co-Generation plant is used to generate chilled water for air conditioning or refrigeration. In this case, the system produces 3 sources of energy simultaneously rather than just 2 conventional sources i.e. Co-Generation. An Absorption Chiller and Waste Heat Recovery boiler are the components linked to the system to provide this functionality.

Absorption Chillers provide an economical and environmental alternative to conventional refrigeration. It eliminates ozone depleting refrigerants and reduces overall air emissions by combining efficiency and low emission power generation equipment for maximum total fuel efficiency. The refrigerants are derived from either the use of hot water, steam, direct heat via combustion or a combination of all three.


With this integration, operationally, the hot water from the cooling circuit of the plant serves as drive energy for the Absorption Chiller. The hot exhaust gas from the gas engine can also be used as an energy source for steam generation, which can then be utilised as an energy source for a highly efficient, double-effect steam chiller. Up to 80% of the thermal output of the Co-Generation plant is thereby converted to chilled water. In this way, the year round capacity utilisation and the overall efficiency of the Co-Generation plant can be increased significantly.


Climate protection and sustainable economical primary power generation has become a new emphasis around the world given global climate changes. Our integrated technologies represent an optimal solution for a year-round efficient source of cooling and heat, especially when used in conjunction with a gas engine Co-Generation plant. Our global partners, namely General Electric Inc. and 2G AG have more than 6000 integrated systems delivered worldwide.
