Evaluation of Combined Production of Heat and Electricity on the Cogeneration Unit

Abstract

The purpose of currently contribution is to analyse and compare effectivity of cogeneration unit in each summer and winter season. The main idea of combined heat and energy production is to reduce usage of primary fuels and with that connected reduction of pollutions due to the integration of renewable energy sources and with regard to the natural environment. Presented contribution is dedicated on issue on the operation of a cogeneration unit integrated in central heating system.

Modeling and Optimizing the Performance of an Industrial Trigeneration Unit

“…Alongside an increased overall efficiency, CCHP also offers a reduction in greenhouse gas emissions [6,7]. Usually, the overall efficiency of CCHP varies from 80% to 93% [8] and the efficiency of the CHP itself can reach 80% [3,6]. For a comparison, a conventional power plant where no heat or cold is produced reaches an efficiency from 27% to 40% [9,10].…”
