Effect of insulation on the energy and exergy performances in Diffusion Absorption Refrigeration (DAR) systems

Development of cooling systems on the basis of absorption water-ammonia refrigerating machines of low refrigeration capacity

“…The well-known theoretical [13,19,[20][21][22][23][24][25] and experimental studies [14,21] show an unambiguous adverse effect of the elevated outdoor temperature on the energy efficiency of both AWARM and ARM.…”

“…In [22], an analysis of ARM with a solar collector based on two-phase gravity-type thermosyphons is made (the heat source is located in the lower part, and the heat consumer is located at the top).…”

Improving the energy efficiency of solar systems for obtaining water from atmospheric air

“…Papers [29][30][31] present methodologies for thermodynamic calculation and analysis of various cycles of AWRU which makes it possible to define a complex of thermodynamic and energy characteristics of refrigeration cycles in a wide range of operation parameters, including modes of obtaining of water from atmospheric air. At the same time, there is no information on internal processes of heat and mass transfer, which makes impossible to use them for the design of real structures of AWRU and systems for obtaining of water from atmospheric air, in papers [29][30][31].…”

Modeling of Thermal Modes of the Reflux Condenser of the Absorption Refrigeration Unit

“…At the same time, ARUs have increased power consumption in comparison with similar compression models [6][7][8][9][10]. In our opinion, this situation is due not only to the imperfection of their refrigerating cycle, but also to the lack of appropriate scientific and engineering developments.…”
