Abstract: One of the necessities of human beings in this century is the potable water supply. This supply has more environmental benefits if the potable water is supplied by renewable energy resources. In this paper, a combination of combined cooling and power system (Goswami cycle), with the reverse osmosis and sodium hypochlorite plant powered by geothermal energy resources is proposed. The products of this system are electrical and cooling energy, potable water, hydrogen and salt. To investigate all of the system aspects, energy, exergy, economic, exergoenvironmental, and environmental analyses are performed. In environmental analysis, the social costs of air pollution are considered. It means that for the same amount of system electrical power produced by non-renewable energy resource power generation systems, the produced air pollution gases and their costs considering the social cost of air pollution are quantified. In this regard, four scenarios are defined. Results show this multi-generation system produces 1.751 GJ/year electrical energy, 1.04 GJ/year cooling energy, 18106.8 m 3 /year potable water, 7.396 Ton/year hydrogen, and 3.838 Ton/year salt throughout a year. The system energy and exergy efficiencies are equal to 12.25%, and 19.6%. The payback period time of this system is equal to 2.7 years.
