Usage of thermal energy storage (TES) for storing energy is a favourable technology which is used in current years. The normal TES in building applications is water which is used in the heating system. Recently, PCM technology improvement helps to use different types of PCMs for increasing...

Grate coolers are widely used in cement industries to recover heat from hot clinker, coming out from the rotary kiln. This study focuses on improving the energy, exergy and recovery efficiencies of a grate cooling system through the optimization of its operational parameters such as masses of...

Refrigerator-freezers play an important role in the preservation of perishable food in warm and humid climates. Experiments were conducted in a controlled chamber to investigate the effects of the ambient temperature, cabinet load, thermostat setting and an open surface water pan on the heat...

Electric motors consume in between 30% and 80% of the total industrial energy use for few selected countries around the world. It was identified that many motors are operated under loaded conditions. In some cases, motors are operated even at 3–16% of their full loads. These low loads can be...
