in this paper by the introduction of the basic equipment of a solar cooling system, solar hydrogen ammonia refrigeration system as a solar cooling technique will be discussed. using heat collector and absorption refrigeration allows us to use residual heat, for cooling, heating and producing hot water and boiling water .this research focuses on methods of heat transfer from the sun into the gen...

Early experimental results of a research program to investigate the practicality of replacing the Solar Rating and Certification Corporation four day rating procedure with a more cost effective rating method for generic solar domestic hot water systems are reported. The generic systems experimental procedure and facility are described. Results from four experiments give an initial indication th...

nowadays two important discussions in academic parties all over the world are energy crisis and environment crisis. one of the strategies to deal with these crisises is using clean, renewable and domestic energy sources. one of the best renewable energies that can be used in different scales is solar energy. in iran which is considered among the greatest countries that receive huge amount of so...

Energy conservation through energy storage combined with intensive use of renewable energies will support the effort to meet the objectives of reduction of climatic gases formulated in the Kyoto protocol. Potential studies have shown that in Germany about 20 – 25 % of the end-energy consumption for space heating and domestic hot water can be covered by solar energy. Solar district heating with ...

Concentrating solar collectors of low concentration ratio can supply hot water or process heat at intermediate temperatures, i.e. 80 to 180 C, where flat plate collectors are not effective, and for which there are a number of industrial, domestic and rural applications. This paper studies the potential applications of this technology and presents case studies to prove its feasibility.

A TRNSYS component (Type 262) has been written to simulate a concentrating PV/Thermal collector. The component is based on a dynamic model of a concentrating PV/Thermal collector, which includes thermal capacitance effects, and detailed equations describing the temperature dependent energy flow between the collector and surroundings. The CHAPS system, a 30x concentration parabolic trough PV/The...
