Air conditioning is an important part in building services world-wide in both commercial and residential buildings. With the general attempt to reduce the usage of fossil fuels and increase the usage of green solutions, the market for solar air conditioning is growing rapidly. Solar air conditioning combines solar thermal absorbers to transfer solar radiation into heat with heat-driven cooling ...

Based on the conjectured existence of primary solar emanations (plasma flows from the solar surface), a model for the Origin of the Fast Solar Wind, and the creation and heating of the coronal structures is developed. Preliminary results reproduce many of the salient observational features.

The primary energy consumption in residential buildings is determined by the envelope thermal characteristics, air change, outside climatic data, users’ behaviour and the adopted heating system and its control. The new Italian regulations strongly suggest the installation of centralized boilers in renovated buildings with more than four apartments. This work aims to investigate the differences ...

Velocity and magnetic field fluctuations in the solar wind show evidence that non-linear turbulent dynamics are present in the interplanetary medium. The cascade of energy created by these turbulent processes may provide a mechanism for in situ heating of the solar wind plasma. We perform three studies analyzing the turbulent energy cascade at 1AU using 10 years of data from the Advanced Compos...

A wide range of existing power technologies can make use of the solar energy reaching Earth. Basically, all those ways can be divided into two basic categories: transformed for use elsewhere or utilized directly – direct – and involving more than one transformation to reach a usable form – indirect. The Solar Chimney Power Plant (SCPP) is part of the solar thermal group of indirect solar conver...

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...

This paper presents a theoretical and practical analysis of the application of the thermoeconomic method. A furnace for heating air is evaluated using the methodology. The furnace works with solar energy, received from a parabolic trough collector and with electricity supplied by an electric power utility. The methodology evaluates the process by the first and second law of thermodynamics as th...
