Solar water heating system technology is described and the scale of the International solar water heater market is surveyed. New product developments for both direct solar water heating and solar boosted heat pump water heating are outlined. Procedures adopted by the International Standards Organisation for assessing solar water heater performance and quality are discussed.

Solar air collectors have various applications: on the one hand, they can be used for air heating in cold seasons; on the other hand they can be used in summer to evacuate the warm and polluted air from residential, offices, industrial, and commercial buildings. The paper presents experimental results of a solar collector air, under the climatic conditions of the Southeastern Europe. The relati...

Passive solar design is an economical way of using solar energy in buildings. The thermal behavior of the buildings within its environment over a period of time can easily be predicted using accurate and simple analytical tools. This provides designers the information necessary to satisfy the occupant’s needs, reduce peak cooling/heating power demands, reduce the size of air conditioning/heatin...

Solar desiccant cooling is widely considered as an attractive replacement for conventional vapor compression air conditioning systems because of its environmental friendliness and energy efficiency advantages. The system performance of solar desiccant cooling strongly depends on the input parameters associated with the system components, such as the solar collector, storage tank and backup heat...

In this study, heat transfer and aerosol deposition in the under-floor and baseboard heating systems have been investigated, numerically. The aim of this study is a comparison between these heating systems. This comparison obtains the optimal heating system with low suspended particles in the air. Computational fluid dynamic with Eulerian-Lagrangian method has been used to simulate fluid and pa...

World-wide water scarcity, especially in the developing world, indicates a pressing need to develop inexpensive, decentralized small-scale desalination technologies which use renewable resources of energy. This paper provides a comprehensive review of the stateof-the-art in one of the most promising of these technologies, solar-driven humidification-dehumidification (HDH) desalination. Previous...

Introduction Growing tomatoes in greenhouses allows producers to grow plants at a time when it would be impossible to grow outside because of the weather. The sole purpose of a greenhouse is to maintain an environment that promotes optimum production. Solar energy from the sun provides both sunlight and heat, but growers must provide a system that maintains the optimum growing environment in th...

The solar façade of the FIAT Research Center (CRF) was realized recently near Turin in Italy, under cooperation between CRF and Politecnico di Milano. The photovoltaic elements, that has a total power of 19.5 kWp, produces electric energy, while the forced air circulation beneath the modules recovers the thermal fraction of captured solar radiation and cools the cells as well. The electricity g...

There is considerable interest in understanding how ectothermic animals may physiologically and behaviourally buffer the effects of climate warming. Much less consideration is being given to how organisms might adapt to non-climatic heat sources in ways that could confound predictions for responses of species and communities to climate warming. Although adaptation to non-climatic heat sources (...
