Abstract
Pressure and depletion, scarcity, and high costs of non-renewable resources in Jordan and the world in general
called searching for the use of environmentally and friendly alternative renewable energy resources.
The most important concern for Jordanian families with low- middle income in the winter season is the
availability of a source of heating; this is because of its high cost. However, the relentless in the field of
alternative energy research helped to reach the best results, especially in regions that were classified with the
highest wavelength during the winter season. Jordan in one of these regions where most of its areas are
characterized by availability of sunny days in most of seasons, and for a long period of the day. Karak city, in the
southern region of Jordan, is one of Jordanian cities that is exposed to sunny days throughout most of season,
and hence the investment in alternative energy is very effective.
In this research, a model was designed for a house whose southern façade contains a Trombe Wall system.
The system consist of layers that allow the exploitation of the solar irradiation that reaches the two-layer glass
and open from the top and bottom in the inner layer to accelerate the heating of the air, which in turn gains the
concrete wall the heat that is transmitted through the wall and stored for heating the house. Two methods were
used to analyze the Trombe Wall system. The first is the Numerical method, where the wall gain is equivalent to
5.55â—¦C at the outer layer in the first time step, which means that the wall works well. The second method is using
the software (Ansys), where the data were entered to the program and a simulation was made, as the system
recorded, after two days, the maximum of temperature was 83ÌŠc and the maximum amount of energy gained was
equivalent to 18,000W. This system saves 69% of the energy used for heating.
