We established a three-dimensional finite element model of thermoelectric module based on low-temperature thermoelectric material bismuth telluride and medium-temperature thermoelectric material filled-skutterudite. The material properties of the thermoelectric materials such as the Seebeck...

The performance of a novel heat exchanger unit (‘Solasyphon’) developed for a solar hot water system was experimentally investigated under indoor and outdoor operating conditions. The ‘Solasyphon’ can be easily integrated to an existing single-coil hot water cylinder avoiding the need...

In order to enhance rate of heat transfer to flowing air in the duct of solar air heater and in heat exchanger or in cooling of turbine blade various turbulence generators viz. ribs, baffles and delta winglets are considered as an effective technique. Investigators reported various turbulence...

An experimental system was developed and tested in order to investigate the energetic performance of a solar photovoltaic system (PV) assisted earth-to-air heat exchanger (underground air tunnel) that is used for greenhouse cooling at the Solar Energy Institute, Ege University, Izmir, Turkey....

Air solar heaters have more and more applications in many areas, including the building sector, food industry, and agricultural sector. This paper presents a novel construction of a forced air solar heater based on a confined single slot jet of air impinging on the flat surface of an absorber...

Typically, a great deal of heat is wasted in the drainage systems of large-scale public shower facilities, such as those in schools, barracks, and natatoriums. This paper enhances a heat pump system used in public shower facilities for exhaust heat recovery. The system consists of three sections...
