| Abstract | ||
| The energy saving is very important in the practical application engineering . This research studies on this subject in the field of air conditioning. A numerical program has been developed to obtain the thermal response of different walls to energy sources ( solar and ambient temperature ) in summer of Iraq. Anew local natural insulation is used to reduce heat gain to air-conditioned space. This work proposed to used local natural insulation from palm fiber , local cane mat and local plastic mat to save energy required to condition a space . A finite element solution for heat flow through wall is used with suitable iteration solution where boundary conditions are varying due to solar radiation and environment thermal load. The result- in saving of about 50% of energy that may pass through walls when used mat cane local compared to the mat plastic local and palm fiber. | ||
