In this paper, a detailed parametric study on a dual-mode silica gel–water adsorption chiller is performed. This advanced adsorption chiller utilizes effectively low-temperature solar or waste heat sources of temperature between 40 and 95°C. Two operation modes are possible for the advanced...

We have investigated analytically the performance of the thermally driven, advanced three-stage adsorption chiller utilizing low-grade waste heat of 50°C and lower temperatures as the driving heat source, in combination with a heat sink (cooling water) of 30°C. The closed cycle chiller for use...

A huge amount of waste heat is emitted annually to the environment by energy intensive industries. Thermally activated advanced absorption cycles can be promising candidates for utilizing the waste heat of industry sector. In such absorption systems, it is desirable to utilize the waste heat...

This study aims at exploiting optimal configurations of technologies combined with co-generation theoretically based on a linear optimization model. With the objective function defining primary energy consumption to be minimized, optimal solutions are derived analytically. They describe the...

Load-leveling hyper energy converting and utilization system (LHECUS) is a hybrid cycle which utilizes ammonia–water mixture as the working fluid in a combined power generation and refrigeration cycle. The power generation cycle functions as a Kalina cycle and an absorption refrigeration cycle...

Psychrometry and solar radiation of Perth in western Australia, and Shanghai in China, are examined in some detail. The aim is to provide assistance in choosing collector technologies and sorption cycles for air conditioning applications for climates prevalent in Australiasia.

It is necessary for Japan to support the development of desulfurization policies of China to solve global and local environmental problems. This study proposes a "double clean development mechanism" to reduce both CO2 and SO2 emissions at the same time. The purpose of this study is to...

We have developed a gas-turbine cogeneration system that makes effective use of the calorific value of the volatile organic compound (VOC) gases exhausted during production processes at a manufacturing plant. The system utilizes the high-temperature exhaust-gas from the regenerative thermal...
