Sorption-based heat transformation and storage appliances are very promising for utilizing solar heat and waste heat in cooling or heating applications. The economic and ecological efficiency of sorption-based heat transformation depends on the availability of suitable hydrophilic and hydrothermally stable sorption materials. We investigated the feasibility of using the metal-organic frameworks...

Solarthermal plants can be supplemented with a seasonally operating geothermal deep probe and a heat pump, thus creating an energy supply system in which these devices support each other in an ideal manner. The system promises high shares of renewable energy and high efficiency of the solar and the geothermal system at the same time. This report introduces the concept of the system, explains it...

an investigation on the thermal performance of the soil as geothermal heat energy storage medium has been conducted. the thermal characteristics of the soil storage and the heat transfer from a heat exchanger in the soil, surrounding and bottom surface will be discussed. this investigation forms a contribution to a project to realize such storage to be charged from a solar heating system. this ...

Typical meteorological year (TMY) data can be used in various fields and, based on their reliability, industrial areas. For example, the operability of a solar-assisted thermal heat pump, which is an integrated system, largely depends weather conditions. Furthermore, accurate TMY are essential for quantitative designing heating and cooling systems, use direct climatic sources such as solar air ...

The heat pumps system is one of the most remarkable that widely used around world, their capacity different according to necessity. energy consumption in those systems will limit effectiveness. This study try prove positive reactance new changes (the additional exchanger) on pump work, where power reduce about (13-17%). includes experimental results laboratory model, which has been manufactured...
