The energy transition, originating in the limitation of fossil resources and greenhouse gas (GHG) emission reduction, is basis many studies on renewable energies different industrial applications. diffusion absorption refrigeration machines are very promising insofar as they allow use (solar, geothermal, waste gas, etc.). This technology often considered an alternative to vapor compression syst...

Renewable energy used for refrigeration applications has become essential very recently due to the fossil fuel crisis and global warming problem. Moreover, using photovoltaic PV generate electricity than inverters storage represents a high-cost process. This study aims investigate opportunity of output directly operate system. The absorption system uses heat as an source generator that drives d...

Refrigeration is one way to maintain the temperature of a material or room at lower level than ambient conditions around it by absorbing heat from room. The refrigeration system that widely used today for industrial purposes use vapor compression cycle, where in this cycle components has an important role compressor. Over time, performance compressor will decrease, so affect absorption process ...

Cogeneration can improve energy utilization efficiency significantly. In this paper, a new ammonia-water system is proposed for the cogeneration of refrigeration and power. The plant operates in a parallel combined cycle mode with an ammonia-water Rankine cycle and an ammonia refrigeration cycle, interconnected by absorption, separation, and heat transfer processes. The performance was evaluate...

The present work investigates the thermodynamic optimality of a double-effect vapor absorption refrigeration system (VARS) driven by blowdown heat 210 MW thermal power plant at Badarpur using response surface methodology (RSM). RSM helps to develop relation amongst decision variables and second law efficiency vi se cond-order nonlinear polynomial regression equation. In addition, analysis varia...

For most of the last fifty years, refrigeration and heat pump systems have been based on cycles using a fluorocarbon as the working fluid. Hovvever, with the discovery that fluorocarbons may have a profoundly detrimental effect on the earth ·s atmosphere. it has become necessary to find a suitable replacement for a fluorocarbon based refrigeration cycle. Such a replacement must perform comparab...
