Total energy consumption by com. and residential buildings in the US nears 40 Quads. Approx. 1/3 of that energy use is due to space heating and cooling. Recent anal. of materials that comprise the building envelope would benefit from smarter windows that m ...
The upward flow boiling experiments were carried out in a flat aluminum extruded multiport tube, which is composed of 7 parallel rectangular channels (1.1 mm × 2.1 mm) with hydraulic diameter of 1.4 mm. Two refrigerants, R245fa and R1234ze, the latter a re ...
Within the challenge of sustainability, climate change mitigation and energy supply a promising way of more rational energy conversion is decentralized power generation and the co-production of power and heat. The combination of a solid oxide fuel cell (SO ...
The identification of a suitable combined electricity production cycle depends on the heating and cooling requirements of the respective industrial process. Due to the large number of options an exhaustive enumeration of all the possibilities is not realis ...
The energy sector is not only a major driving force of climate change, it is also vulnerable to future climate change. In this paper, we analyze the impacts of changes in future temperature on the heating and cooling services both in terms of global and re ...

Cement production is an energy intensive industrial process that requires heat to be supplied at high temperature levels under the constraints of gas-solid heat exchange phenomena and the kinetics of chemical reactions. In this paper, the use of Pinch Anal ...
Central solar heating plant is one of the most profitable, the most efficient and the most easily installable solar technology. However, there is significant limitations for its installation on all the northern roof. There is a gap between the summer heat ...
