In this work the effect of the elbow-bend geometry and the effect of the tube arrangement on the performance of air-to-water heat exchanger is studied experimentally. In elbow-bend heat exchanger, the direction of the working fluid is bended at 90 degrees to its inlet direction. The heating or...

The article provides a review of solar radiation for this climatological zone, a solar house with a water flat plate collector and three storage solar heating systems, and industrial systems which was designed and constructed in order to drying ceramic and fluidization of bituminous asphalt mixing.

Building legislation along with environmental and comfort concerns are increasingly driving designers of building services and air conditioning equipment towards more energy efficient solutions. Heat pipe technology is emerging as a viable, efficient and environmentally-sound technology for...

In this paper, exergy transfer effectiveness is defined to describe the performance of heat exchangers operating above/below the surrounding temperature with/without finite pressure drop. It is discussed systemically that the effects of heat transfer units number, the ratio of the heat capacity...

In the 20th Century many buildings became totally dependent on fossil fuel energy to make them habitable. Recent legislation and building regulations, however, ensure that designers are contracted to aim for zero carbon sustainability or buildings which function with much lower levels of fossil...
