چکیده
Human demand for energy has reached unprecedented levels. A high-efficiency chemical heat pump (CHP) that uses solar thermal as source called SCHP system been studied decades in our laboratory. The (SCHP) using CaSO4∙1/2H2O/CaSO4 can store the form of and release it hot cold heat. This study presents a simplified three-dimensional unsteady model reactant bed releasing step system. is programmed by finite difference method enabled operation Microsoft Excel on personal computer instead other complex programming languages workstations etc. Even simulate heat/mass transfer under different evaporator temperatures. simulation results temperature distribution overall hydration conversion are good agreement with experimental results. Furthermore, effects fins inserted thickness enhancement hot/cold power were shown at

Performance Improvement of a Heat Pump Assisted Solar Water Heating System
Details of a heat pump assisted solar water heating system, is briefly described. Refrigerants compromising of Fluorocarbons and Chlorofluorocarbons have been generally used as the working fluid. But due to its ozone depletion effect and high Global warming potential, they have been replaced by synthetic refrigerants such as R22, R134 etc. The heat pump utilizing such refrigerants has shown to ...
متن کاملNumerical Investigation of Roofing Materials Effect on Solar Heat Gain in Different External Conditions
In this study, the thermal performance of three kinds of roofs with different heat capacity and thermal conductivity under different external conditions has been investigated using a numerical method. For this purpose, the combined solar radiation, conduction and convection heat transfer were calculated implicitly in terms of a one-dimensional finite difference method. Different high and low so...
متن کاملNumerical Investigation of Effective Parameters on Efficiency of Solar Chimney
The environmental pollution crisis caused by the excessive use of fossil fuels and the risk of the destruction of natural resources and reserves, as well as the excessive production of greenhouse gases and, consequently, global warming, led many energy researchers to use renewable energy As a fossil fuel alternative. Solar chimneys are one of the types of renewable energies that have been taken...
متن کاملperformance improvement of solar stills via experimental investigation
abstract: there is always a need to increase a distillate output of solar still. if plates will be used inside solar still then distillate output of solar still are expected to increase. hence, an experimental study is conducted to improve distillate output of basin solar stills by increasing the effective surface area with the help of different plates. for the purpose of experiment, three sola...
متن کاملStudy on the Performance of a Ground Source Heat Pump System Assisted by Solar Thermal Storage
A ground source heat pump system (GSHPS) utilizes a relatively stable underground temperature to achieve energy-saving for heating and cooling in buildings. However, continuous long-term operation will reduce the soil temperature in winter, resulting in a decline in system performance. In this research, in order to improve the system performance of a GSHPS, a ground heat pump system integrated ...
