Pipeline Corrosion Failure in an Absorption Chiller

open access: yesProcedia Engineering, 2015
AbstractAbsorption chillers generate chilled water by employing as refrigerant water which is evaporated at low pressure. The steam produced is then absorbed by a concentrated LiBr solution. The materials employed for the construction of this kind of plant are usually copper and stainless steel.

A Review of single-effect solar absorption chillers and its perspective on Lebanese case

open access: yesEnergy Reports, 2021
Solar cooling systems, specifically solar absorption cooling systems, are becoming an attractive subject since they are great alternatives to the conventional cooling systems which lead to high electrical consumption. In addition, this system can provide

A Methodology for Multi-criteria Assessment of Chiller Plants for Building Setup Utilising Waste Heat and Solar Energy

open access: yesSustainability Analytics and Modeling, 2023
Incorporating a central chilled water hub within an eco-industrial park may boost cost-cutting and carbon reductions. Yet, there are various ways to power it, each with its own set of advantages and disadvantages in respect of cost, environmental impact,

Performance of absorption chillers in field tests [PDF]

open access: yesApplied Thermal Engineering, 2018
Absorption chillers can use waste heat, solar heat, or excess heat by cogeneration facilities to supply chilled water. Therefore, absorption chillers are important components for poly-generation, which can improve plant utilization and efficiency of the overall energy supply system.

Effects of Coupling Combined Heat and Power Production with District Cooling

open access: yesEnergies, 2023
Over the past decades, combined heat and power production (CHP) has proven itself to be an efficient means of meeting both heat and power demands. However, high efficiency can be achieved with CHP plants when the heat load is sufficient, while lower ...
