Waste heat driven absorption/vapor-compression cascade refrigeration system for megawatt scale, high-flux, low-temperature cooling

Performance comparison between a conventional vapor compression and compression-absorption single-stage and double-stage systems used for refrigeration

“…The numerical results showed a reduction of the compressor work up to 52% if R134a and LiBr/H 2 O were used in the compression-absorption cascade system compared with a classical vapour compression system using R134a. Garimella et al [6] developed a computational model of a cascade absorption-vapor compression system with a high temperature lift in order to provide different levels of temperature: low temperature refrigeration, space conditioning and water-heating applications in a naval ship. Jain et al [7] studied a thermodynamic model for cascade vapor compression-absorption system (CVCAS) has been developed which consists of a vapor compression refrigeration system (VCRS) coupled with single effect vapor absorption refrigeration system (VARS) based on first and second laws.…”

Analysis of the Construction and Operation of the Cascade Refrigeration

“…In [5] is presented steam absorption refrigeration system with refrigerants LiBr-H 2 O to obtain temperatures below -40°C, whose work has been compared with the two-stage steam engine. Taking into account the operating temperature and the heat was reported that the installation maintains high value of COP in a wide range of operating conditions.…”

An innovative ecological hybrid refrigeration cycle for high power refrigeration facility

“…This is the main difference between the possibilities of contemporary industrial adsorption and absorption technologies. There is also scientific interest in hybrid sorption-compression cycles, their application however, has other aims and refrigerants than presented here (Banker et al, 2008;Garimella et al, 2011;Han et al, 2013;Zheng and Meng, 2012).…”
