Abstract

The performance of a proposed air conditioning system under the weather of Mosul city / Iraq has been studied and compared with that of the vapour compression system operating at the same condition. For the purpose of reducing the cost of the proposed system, a local desiccant material called local silica gel was used as an alternative to the regular density silica gel which is usually used in the enthalpy wheels. This material was extracted from Ninivite rocks available at south of Mosul city / Iraq. Some of the Physical and thermal properties of this material were experimentally determined and compared with those of the regular density silica gel.

Highlights

  • The demand for electric power is increasing overall the world during summer season when the demand for electric powerApplication of Ninivite Silica Rocks as a desiccant material in cooling systems.reaches its peak(1)

  • The most material used for this purpose is the regular density silica gel(3) (RDSG), which characterized by the high ability to adsorb humidity from the air or releasing humidity to the air when it passes through the wheel as a result of the differences in the water vapour pressure between the air and the desiccant material

  • Chemical composition of Ninivite silica rocks existing south of Mosul city studied for the first time in 1989 (5)

The demand for electric power is increasing overall the world during summer season when the demand for electric powerApplication of Ninivite Silica Rocks as a desiccant material in cooling systems.reaches its peak(1). Application of Ninivite Silica Rocks as a desiccant material in cooling systems. The most material used for this purpose is the regular density silica gel(3) (RDSG), which characterized by the high ability to adsorb humidity from the air or releasing humidity to the air when it passes through the wheel as a result of the differences in the water vapour pressure between the air and the desiccant material.
