Absorption Chillers and Heat Pumps, Second Edition
The term Absorption Chillers and Heat Pumps refers to a group of technologies that transfer heat from a low temperature to a high temperature. Such technologies include refrigeration systems as well as heat pump heating systems. Such a transfer requires a thermodynamic input in the form of either work or heat. This is made clear in the Clausius statement of the Second Law of thermodynamics.

The thermodynamic implications of the Second Law for heat pump technology are the factors that complicate the application and understanding of this technology. Even when the Second Law is not explicitly applied in a heat pump analysis, its requirements are in force implicitly through the properties of the working fluids. In simplified terms, we can say that transferring heat from a low temperature to a high temperature requires an expenditure of energy.
Building cooling is a major factor in demand peaks and, thus, running an all-electric mechanical room often leads to high demand charges.

The primary applications for aqueous LiBr technologies are in building air-conditioning systems, which is a field that is constrained by many forces, including economics, governmental regulations, and the industry knowledge base. The relative importance of these forces varies significantly by geographical regions, resulting in large geographical differences in absorption technology utilization and manufacturing.
