AB - At present, energy efficiency is a very important issue and it is power  generation facilities, among others, that have to confront this challenge.  The simultaneous production of electricity, heat and cooling, the so-called  trigeneration, allows for substantial savings in the chemical energy of  fuels. More efficient use of the primary energy contained in fuels  translates into tangible earnings for power plants while reductions in the  amounts of fuel burned, and of non-renewable resources in particular,  certainly have a favorable impact on the natural environment. The main aim  of the paper was to investigate the contribution of the use of adsorption  chillers to improve the energy efficiency of a conventional power plant  through the utilization of combined heat and power waste heat, involving the  use of adsorption chillers. An adsorption chiller is an item of industrial  equipment that is driven by low grade heat and intended to produce chilled  water and desalinated water. Nowadays, adsorption chillers exhibit a low  coefficient of performance. This type of plant is designed to increase the  efficiency of the primary energy use. This objective as well as the  conservation of non-renewable energy resources is becoming an increasingly  important aspect of the operation of power generation facilities. As part of  their project, the authors have modelled the cycle of a conventional heat  power plant integrated with an adsorption chiller-based plant. Multi-variant  simulation calculations were performed using IPSEpro simulation software.
