Trigeneration - the generation of useful energy all year round.

Combined Refrigeration, Heat and Power (CCHP) systems, also called trigeneration systems, are a mixture of combined plants and absorption refrigeration units.

INNIO Jenbacher gas engines provide an excellent solution for air conditioning and / or refrigeration. The combined equipment ensures high performance and low emissions. Absorption refrigeration units are an economical and environmentally friendly alternative to conventional refrigeration systems with vapor compression refrigeration units. The combination of these two elements provides excellent high fuel efficiency and a reduction in overall emissions.

How it works

Combining a cogeneration plant with an absorption refrigeration system makes it possible to use the power of the CHP plant more efficiently. After all, excess heat is used for cooling when there is no need for heating in the summer. The hot water produced by cooling the unit serves as the driving energy for the absorption chiller. And the exhaust gases from the engine are used to generate steam, which becomes the energy source for the double-acting desuperheater. As a result, up to 80% of the thermal power of the CHP plant can be used for water cooling.


Benefits and features

  • Compared to conventional refrigeration technologies, absorption air conditioning systems are much more efficient and produce much less NOx emissions
  • When working with heat, trigeneration uses a relatively inexpensive "excess energy"
  • The generated electricity can be supplied to the public grid or used to cover the station's own needs
  • In the cold season, heat can be used to cover heating needs
  • Simple, high quality ABCM design with no moving parts ensures low maintenance costs and long overhaul intervals
  • Quiet operation
  • Bi-fuel option available
  • Reduced operating and lifecycle costs
  • The use of water as a refrigerant eliminates the need for ozone depleting substances.
