Greenhouse gas emissions associated with two air-conditioning systems for a university building
Recognizing the rise of global life standards, the associated energy consumption, and the widespread use of air-conditioning systems, there is a clear necessity to evaluate the environmental loads associated with energy supply systems. This study applied

Pipeline Corrosion Failure in an Absorption Chiller
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
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

Performance of absorption chillers in field tests [PDF]
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
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 ...
