Interconnected Heat Pipe Solar Collector

This paper deals with the performance of a heat pipe solar collector. The solar collector consisted of an interconnected heat pipe so as to reduce the production cost by using an interconnected heat pipe because all the heat pipes can be evacuated, sealed and tested at once. Performance of a prototype of the heat pipe solar collector was experimentally examined, and the results were compared wi...

Solar Heat for Industrial Processes

Economic optimization and comparative study of solar heat pumps

In this paper, an economic study of solar heat pumps and an investigation of differences between solar heat pumps and conventional heat pumps—based on their performances and energy consumption—are conducted for a residential apartment located in Austin, Texas, USA. Heating in the apartment is provided via a solar heat pump during the cold months of a year. Solar collectors are used to meet the ...

Industrial Process Heat Applications of Solar Energy

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.

heat transfer design of solar absorption refrigeration system by using solar panels

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...
