“…Resultingly, adsorption chillers are independent of the power supply and have a long lifetime. On the other hand, bulkiness (large dimensions and mass) and high design requirements due to low pressures are the main disadvantages of adsorption chillers [21][22][23][24][25].…”

Forecasts to 2030 indicate that demand for electricity will increase from 2% to 3% per year, and due to the observed high rate of development of the world economy, energy demand will continue to increase. More efficient use of primary energy has influence on reduction emissions and consumption of fuel. Besides, reducing the amount of fuel burned, it reveals a beneficial effect on the environment. Since extraction-back pressure turbines have some limitations, including the restriction of electricity production due to limited heat consumption in summer. The paper discusses the possibilities of integrating the adsorption aggregate with a combined cycle gas turbine and its impact on the operation of all devices. Simulations are performed on Sim tech IPSEPro software. The obtained results confirm that the adsorption aggregate, using a low grade of thermal energy, does not affect the operation of the gas and steam cycle and allows the production of electricity at a constant level. The calculated chemical fuel energy utilisation factor was 85.7% in cogeneration and 75.6% in trigeneration. These factors indicated a reduced utilisation of chemical fuel energy; however, this reduction is caused by a lower COP for adsorption chillers. Besides, the adsorption aggregate additionally generates chilled water for air conditioning or other technological processes, which stands for an added value of the innovative concept proposed in the paper.

“…The constant feeding of water from an external source results in producing condensate that is devoid of the substances dissolved in the feed water. Where the system is fed by saline water, an extra product apart from the cooling effect is desalinated water [6][7][8]. The first hybrid systems using adsorption cooling systems provided both heating and cooling effect.…”

Original scientific paper https://doi.org/10.2298/TSCI19S4143S 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.

“…43°C.Their operating cost is much lower as compared with other types of chillers;; they have a long lifetime and are not dependent on power supply. Adsorption chillers also have some disadvantages including their large dimensions and mass, considerable development costs or high design requirements due to the necessity of maintaining very low pressures [1,2,3,4,12,13,14,15]. This analysis concerns the impact of an adsorption chiller on a gas and steam cycle utilising a gas turbine is Siemens SGT5-4000F [11].…”
