Trigeneration is the simultaneous production of useful power, heat, and cooling from a gas engine (cogeneration - or CHP - deals with only heat and power, not cooling). Dresser-Rand Trigeneration systems are available with electrical output ranging from 100kWe to 2MWe.
How does trigeneration work?
Cooling is achieved using a CHP system's heat, carefully matched and close coupled to an absorption chiller to ensure optimum plant efficiency. The chiller is assembled with all necessary pumps, heat exchangers, and controls in an engineered package of the same construction as the matched CHP unit. Cooling of the absorption chiller package and engine system is provided by a separate closed circuit cooling water system controlled by the integrated trigeneration control system. Dresser-Rand trigeneration systems are designed to precisely match client requirements for electricity, heating, and cooling.
What applications can trigeneration be used for?
Trigeneration can be applied to air conditioning systems for buildings, and also has applications in industrial processes where there are concurrent and continuous uses for both heating and cooling.
