Abstract
The use of air conditioning (AC) systems is widespread in Saudi Arabia. The primary energy source in this region are electric power stations running on fossil fuels, which have harmful environmental impact. A side effects of the increasing use of ACs is the emission of hydrofluorocarbons, which contribute to ozone depletion. The remanufacturing of ACs has been reported as an environmentally friendly alternative due to waste reduction and minimal use of raw materials. This study compares the energy intensities of manufacturing and remanufacturing ACs in terms of environmental and resource economics. This comparison was carried out using an environmental life cycle assessment. Furthermore, a life cycle cost (LCC) analysis was also carried out to determine the most cost-effective option in different sectors from the user's perspective. The results were validated using an uncertainty analysis technique. These findings were used to estimate the manufacturing/remanufacturing energy across multiple use cycles.
