    Abstract

    The use of fossil energy represents the largest source of greenhouse gas emissions among human activities. Thus, world population growth and rapid urbanisation require the development of energy-efficient solutions. In tropical countries,
    climate conditions are almost constant throughout the year and dominated by high temperatures and humidity. Therefore, the need for cooling technologies is tremendous. These cooling technologies consume a significant amount of energy, and a substantial increase in demand is expected in the upcoming years. The main objective of this paper is to analyse the viability of utilising excess heat from industry to produce chilled water in a central district cooling plant using absorption
    technology. The case study considers an urban area located in a tropical region. In the literature, excess heat sources were identified and categorised to find a suitable industry sector to provide a constant excess heat stream. Based on this
    analysis, a district cooling plant with a total cooling capacity of 27.6 MW was modelled and analysed. Furthermore, the demand profile of different consumers, such as households and hospitals, were considered to assess which consumers
    have the highest benefit from the district cooling plant. Finally, an economic analysis showed if the proposed district cooling plant based on absorption technologies is more feasible than a standard chiller plant.
