Abstract
This thesis presents the vapour absorption system based on water as a refrigerant and lithium
bromide solution as the absorbent by applying natural gas, which is available, cheap, and clean as a
source of energy. The absorption system has shown good results for the two major impacts;
economical and environmental. From the environmental point of view, this can be considered as an
ideal solution for the problems concerning the usage of CFC, and its effects on the environment
where ISO 1400 I recommended a full prohibition for the usage of CFC for air conditioning
purposes by 2030.
The severity of the ozone layer destruction problem, due partly to CFCs and HCFCs, has been
calling for rapid development in CFC-free air conditioning technologies. With regard to energy use,
global wanning prevention requires a thorough revision of energy utilization practices towards
greater efficiency. From this perspective, absorption cooling research has drawn the attention of
many investigators, as it does not use ozone depleting substances as refrigerants as well as it can
minimize the use of fossil fuels produced electricity.
From the economics point of view, the cost analysis showed that the proposed system saves 92 % of
electricity power consumption and an overall saving of 33 % of total cost by using the
average annual cost comparison method. The analysis was applied on an air conditioning system of
a fixed steel platform by performing a parametric study. A comparison is performed between
compression air conditioning system and absorption air conditioning system.
