Evaporative cooling consumes fraction of the electricity required by the vapour compression refrigeration system but is only effective in dry weather conditions. A promising method for controlling the incoming air humidity is to use a desiccant wheel before the evaporative cooler. Currently,...

Organic Rankine Cycle converts low grade heat sources into power utilizing organic fluids with low boiling temperature and pressure. In this cycle the design and performance of the expander has a significant impact on the cycle's overall efficiency. This work presents an integrated mathematical...

Efficient thermal management in portable electronic devices is necessary to ensure sufficiently low operating temperatures for reliability, increased installed functions, and user comfort. Using Phase Change Materials (PCMs) based heat sinks offers potential in these applications. However, PCMs...

Adsorption cooling is a promising technology that can effectively utilize waste heat from many industrial processes for refrigeration and air conditioning. Commercially available adsorption systems are based on silica gel/water, zeolites/water and activated carbon/ammonia pairs. These suffer...

With the ever increasing demand for energy, exploiting low-temperature heat sources has seen significant interest recently. The conventional organic Rankine cycle (ORC) is a typical approach used to exploit low-temperature heat sources but suffers from low efficiency. The Kalina cycle is a...
