COGENERATION PLANT FOR AN
ENERGY SUPPLY SERVICE PROVIDER
What is so special about this cogeneration plant can be found on the one hand in the required redundancy of the systems, since the customer must ensure the supply of his customers with energy and warmth at all times. On the other hand, its economical operation is only possible if the warmth energy resulting from the energy production can be used in summer using absorption refrigeration for cooling and air conditioning.
The plant for which Antrok assumed responsibility for the pipework and assembly of components consists of two gas-powered cogeneration plants and two gascondensing boilers with a total heating output of 2 megawatts. The warmth resulting during the production of electricity is fed into multiple cycles: one part is used directly for building heating, another part is stored in two buffer reservoirs of 28,000 l each. In summer, this warmth is used to operate an absorption refrigerator. Using the supply of thermal energy, the temperature dependency of the physical solubility of two substances is used for cold generation. Thermally induced pressure fluctuations in the system are compensated with a pressure maintenance system.
