Now a days, In most of the thermal power plant, where low-pressure steam is being exhausted to the atmosphere as a waste steam. This waste heat could be use to operate many small preheating or cooling equipments or small scale plants. There are many refrigeration systems present for refrigeration and air condition purpose. Such as air refrigeration, vapour compression, vapour absorption etc. In...

In this paper, the performance of a hybrid humidification-dehumidification (HDH) desalination system is experimentally studied. The operates as an Open-Air Closed-Water cycle and utilizes solar air heater to heat input humidifier. An Ammonia absorption refrigeration cooling used condense humid air, producing fresh water. Parameters such temperature relative humidity were measured in different s...

In this article, new multiple-production systems based on the micro-combined cooling, heating and power (CCHP) cycle with biomass heat sources are presented. proposed system, absorption refrigeration subsystems a water softener system have been used to increase efficiency of basic reduce waste. Comprehensive thermodynamic modeling was carried out system. The validation optimization via genetic ...

The cooling of molecules during the adiabatic expansion of supersonic seeded molecular beams is reviewed and illustrated by the example of NO -molecules. The reduction of the Doppler width by collimation of the beam and the cooling to low rotational temperatures brings a significant simplification of the complex NO -absorption spectrum and allows its assignment. The measured rotational tem...

Three combined power and refrigeration system are introduced to compare and analyze for a defined demand and same fuel consumption based on thermodynamic parameters in a 24 hours period. Gas turbine and/or steam turbine are used for power generation and also ejector refrigeration cycle is used to produce cooling. These three systems are named as GER, SER and GSER. The results of three systems a...

Sorption thermochemical storage systems can store thermal energy for the long-term with minimum amount of losses. Their flexibility in working sustainable sources further increases their importance vis-à-vis high levels pollution from carbon-based forms. These be utilized cooling and heating purposes or shifting peak load. This review provides a basic understanding technologies critical factors...

fatigue behavior of a vanadium microalloy steel has been studied in this research. here, microstructure constituents were considered which essentially are dependent on the heat treatment conditions. the results of high cycle fatigue tests revealed that heat treatment procedure and cooling rates have significant effects on fatigue properties. optimal heat treatment cycle of the microalloyed stee...

In this study, the performance of different cooling technologies from energy and economic perspectives were evaluated for six prototype residential Nearly Zero Energy Buildings (NZEBs) within a planned future city district in central Sweden. This was carried out by assessing primary number life cycle cost analysis (LCCA) each building model technology. Projected climate file representing 2050s ...

Possible feedback effects between aeolian dust, climate and ice sheets are studied for the first time with an Earth system model of intermediate complexity over the late Pleistocene period. Correlations between climate and dust deposition records suggest that aeolian dust potentially plays an important role for the evolution of glacial cycles. Here climatic effects from the dust direct radiativ...

Direct discharge of waste heat from internal combustion engines (ICEs) is unfavorable for the efficient and clean fuel utilization. Here, a novel combined absorption-compression cascade refrigeration cycle proposed to efficiently capture low-grade supply cooling capacity food freezing in vessels or refrigerated trucks. The intention this work lies in: i) Comprehensively evaluating performances ...
