The compression-assisted air source absorption heat pump (CASAHP) is a promising alternative heating system in severe operating conditions.
The obtained results may provide a general theoretical tool for the ecological design of four-heat-source absorption refrigerators.
A prototype of NH3-H2O water source absorption heat pump (WSAHP) designed for low temperature heating was experimentally investigated under different working conditions.
The heat supply system combining a conventional boiler with an air source absorption heat pump (ASAHP) has been evaluated as having great potential in energy saving and emission reduction.
This paper studies and analyzes the effect of two internal irreversibilities parameters (the internal irreversibility parameter for generator absorber assembly and the internal irreversibility parameter for condenser evaporator assembly) on the optimal ecological performances of an irreversible three-heat-source absorption refrigerator based on the ECOP criterion.
After the introduction of high-intensity laser light sources, multiphoton absorption has gained a lot of attention during the past five decades, with the first experimental proof for two-photon absorption as the starting point in 1961.
In the shortwave, ({mathrm{H}}_{2}{mathrm{O}}), ({mathrm{O}}_{3}), ({mathrm{CO}}_{2}), ({mathrm{O}}_{2}), ({mathrm{CH}}_{4}), ({mathrm{N}}_{2}), clouds, aerosols and Rayleigh scattering are the modelled sources of absorption and scattering.
The main sources of absorption of inorganic lead are from ingestion and inhalation.
These urinary metabolites are derived from common personal and household products or dietary sources, and absorption may occur through ingestion, inhalation, or dermal routes (National Science Foundation 2008).
With the bandwidth of state-of-the-art semiconductor-based light sources, water absorption is not a severely limiting factor for the axial resolution, provided that the center wavelength is close to the absorption minimum.
