Trigeneration & CHP Absorption Cooling
Combine heat, power and cooling. Use jacket water and exhaust heat from your CHP engines to drive absorption chillers — especially valuable in summer when heating demand falls.
CHP heat that would otherwise be rejected becomes cooling.
A typical reciprocating engine produces jacket water around 90 °C and exhaust gas around 450 °C. In winter that heat serves space and process heating. In summer, absorption chillers turn the same streams into chilled water — keeping the engine fully utilised and the site’s cooling load off the grid.
Jacket-water driven chillers
Single-effect absorption machines driven by engine jacket water (~80–95 °C) for efficient chilled water production.
Exhaust-gas driven chillers
Double-effect or direct-fired machines using high-grade exhaust for higher COP cooling.
Combined circuits
Engineered recovery packages that collect both jacket and exhaust heat and route them optimally between heating and cooling duties.
Year-round economics
Trigeneration improves CHP running hours and payback by creating a summer use for heat that would otherwise be dumped.
