LED (light emitting diode) technology has been developed rapidly in recent years in the area of illumination applications. However, the rate of heat generation increases with the LED illumination intensity. The LED chip temperature is critical to determine the LED lifetime and efficiency. In...

The objectives of this paper are to analyze the heat transfer characteristics during the NH3–H2O absorption process in plate heat exchangers and to develop the experimental correlations of the heat transfer coefficient for the compression/absorption hybrid heat pump application. The parametric...
