A novel combined system that combines a MEE–ABHP (multi-effect evaporation–absorption heat pump) with a VCR (vapor-compression refrigeration) cycle is proposed to simultaneously generate cooling and fresh water. In the combined system, the condenser of the VCR system is replaced by the MEE–ABHP system, where a portion of the fresh water produced in the last effect of the MEE (multi-effect evaporation)...
This paper continues Part 1 of our study and develops a thermoeconomic model of the system with low and high pressure compressors. The thermoeconomic model was used to assess the unit cost of the fresh water and cooling and to evaluate the flexibility of the system for fuel allocation from different electricity and heat energy sources. A parametric analysis was carried out to investigate the effects...
This study proposes a systematic approach of energy and exergy analysis of reverse osmosis (RO) desalination system combined with the gas turbine power plant (GT). Three systems of RO for producing freshwater and a gas turbine for generating the power for the pumps and other equipments are compared in energy and exergy aspects. The first system mechanically couples RO with the power plant; while the...
Fresh water and cold which are produced by desalination and cooling processes are simultaneously utilized in many factories and industries. Energy saving can be possible by integration of desalination and cooling systems. This paper contributes to a new integration scheme of the reverse osmosis (RO) and refrigeration systems. Compressor intercooler and condenser waste heat are recovered to increase...
