Trigeneration for Gas Distributor in Prague

Prague Gas Distribution company (Pražská plynárenská a.s.) – Prague, Czechia has been in operation of trigeneration since 1997. Trigeneration is actually a combination of a cogeneration unit and an absorption cooler. The heat from cogeneration can then be used not only for heating, but it is also possible to produce chilled water, most often for air conditioning the building in the summer.

Originally, a cogeneration unit with a Waukesha F18GLD engine with an output of 260 kWe and 360 kWt and an absorption cooler Carrier 16JB with a cooling capacity of 200 kW were originally installed.

In 2015, the cogeneration unit was modernized. The original Waukesha engine was replaced by a modern MAN engine and the electric power was increased to 350 kWe. The absorption cooler has been retained.
