Abstract

According to predictions, electricity consumption in developed countries will increase three times by 2020 compared with 1970. In contrast, in developing countries, where the population may double by 2020 relative to 1970, there may even be a twentyfold increase in electricity consumption [1]. Other sources predict that increases in electricity demand by 2030 will be approx. 2 ÷ 3% a year. With such a high rate of development of the world economy, the electricity demand will be increasing. Thus, using only renewable sources to satisfy the demand for energy is insufficient and will remain so in the near future. Coal will remain the predominant fuel used to produce electricity. One of the ways to reduce the adverse effect of fossil fuels on the natural environment is to increase the efficiency of use of primary energy. Electricity production is associated with large losses, including in the form of heat which can be used to produce cold with adsorption chillers that can be powered by low-temperature heat. The paper presents the possibility to employ adsorption chillers in power units in order to increase the efficiency of electricity production. Simulation calculations were performed using Sim tech’s IPSEPro software.
