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.
