A novel small-sized integrated solar desalination system with multi-stage evaporation/heat recovery processes is designed and tested in this study. The system consists of four linked collecting units and operates under barotropic and atmospheric pressure. Each of the four units contains a...

For an installation for the heating and cooling of a building that uses refuse and renewable energy, electrical energy savings may be high without any computer control. However, energy savings may be even higher when this installation is with computer control. In this case, the installation uses...

This paper examines the performance of a new Marnoch heat engine, which uses dry air and a pneumatic piston assembly to convert thermal energy to electricity. The system has unique capabilities of operating over temperature differentials less than 100 K. Unlike a common Stirling engine, the...

Independent air dehumidification provides an attractive alternative to traditional coupled air dehumidification with reduced energy use, better humidity control and indoor air quality. According to this concept, latent load is treated by an independent system and the sensible load is treated by...

The present work discusses the potential and the economic feasibility of DH (district heating) delivery using industrial excess heat from a petrochemical cluster at the Swedish West Coast. Pinch Analysis was used for estimating the DH capacity targets and for estimating the cost of heat...

The present work aimed at evaluating the experimental performance of a gas engine heat pump for hot water supply. In order to achieve this objective, a test facility was developed and experiments were performed over a wide range of ambient air temperature (10.9–25.3 °C), condenser water...

CFB (circulating fluidized bed) boiler bottom ash contains large amounts of physical heat. A BAC (bottom ash cooler) is often used to treat high temperature bottom ash to reclaim heat, and to have the ash easily transported. The unit thermal economic indicators of three CFB power plants in China...

This paper investigated the cooling processes of high temperature slags using SHTT (single hot thermocouple technique) and CFD (computational fluid dynamics) method for the purpose of recovering the waste heat. A series of slags with the CaO/SiO2 ratio of 1.1 and different Al2O3 contents were...

In this paper, flash evaporation and thermal vapor compression are used to reduce heat consumption of CO2 capture processes and two improved capture systems are proposed. One is the flash evaporator (FE) and thermal vapor compressor (TVC)-aided system, the other is the heated flash evaporator...

A gas engine heat pump (GEHP) represents one of the most practicable systems which improve the overall energy utilization efficiency and reduce the operating cost for heating and cooling applications. The present work aimed at evaluating the performance of a GEHP for air-conditioning and hot...
