Utilization of Low-temperature Heat by Adsorption Chiller

An Adsorption Chiller Driven by Thermoelectricity

Development of a Solar Powered Adsorption Chiller

Heat driven cooling technologies like vapour absorption and adsorption systems are environmentally friendly. Use of thermal compression in these systems saves precious and fast-depleting fossil fuel resources. Solar energy and low-grade waste heat can be effectively used in running these cooling systems. The present work focuses on the development of a solar-powered vapour adsorption based cool...

Adsorption of Hydrogen Sulfide at low temperature

From an ecological perspective is biogas an important source of energy. It is produced from fermentation of organic material, e.g. household waste and wastewater sludge. The composition of the gas depends on the raw material and varies between 65-85% methane, 15-35% carbon dioxide and small amounts of ammonia and hydrogen sulfide. To use the biogas it is important to purify it from hydrogen sul...

Numerical Simulation of Advanced Adsorption Refrigeration Chiller with Mass Recovery

This paper investigates the thermodynamic framework of a three-bed advanced adsorption chiller, where the mass recovery scheme has been utilized such that the performances of this chiller could be improved and a CFC-free-based sorption chiller driven by the low-grade waste heat or any renewable energy source can be developed for the next generation of refrigeration. Silica gel-water is chosen a...

Low-temperature heat capacities of synthetic pyrope,

The heat capacities of synthetic pyrope (Mg,Al,Si,O,,), grossular (CasAI,SisO12), and a solid solution pyrope,,grossular,, (Mg,,sCa,,,Al,Si,O,,) have been measured by adiabatic calorimetry in the temperature range l&350 K. The samples were crystallized from glasses in a conventional pistoncylinder apparatus. The molar thermophysical properties at 298.15 K (J mol’ K‘) are: c; So298 % H’h, &P Pyr...
