Solar shading can be used to decrease the cooling power demand and cooling energy use but that also reduces the possible benefit for heating with the incoming solar radiation when there is a heating need. The apparent solution is to shade when there is a cooling need and allow solar gains when there is a heating need. This paper presents energy use simulations on such a system set up in a theor...

Abstract Solar photovoltaic (PV) panel is one of the renewable sources energy and produced daily nowadays. systems have efficiency influenced by different factors, such as ambient temperature, solar sunlight, weather, irradiation. The increasing temperature PV decreases its lifetime. Thus, to maintain decrease cell, cooling system required. This paper presents hybrid (water air) method for pane...

Being able to heat and cool the absorption cell of a spectrometer has many benefits. Cooling simplifies the spectrum of the gas in the cell by freezing out rotational and vibrational motion of the gas molecules, while heating increases the population of the excited ro-vibrational states. We designed and prototyped a heating and cooling system for the absorption cell of the FASSST spectrometer [...
