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, 18,106.8 m³/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.

本世纪人类的必需品之一是饮用水。如果饮用水由可再生能源提供，则这种供应具有更多的环境效益。本文提出了一种结合制冷和电力系统（Goswami循环）的组合，以及由地热能源驱动的反渗透和次氯酸钠装置。该系统的产品是电能和冷却能，饮用水，氢和盐。为了调查系统的所有方面，进行了能源，火用，经济，能效环境和环境分析。在环境分析中，考虑了空气污染的社会成本。这意味着对于不可再生能源发电系统产生的相同数量的系统电力，量化产生的空气污染气体及其成本（考虑到空气污染的社会成本）。在这方面，定义了四个方案。结果表明，该多代系统产生的电能为1.751 GJ /年，冷却能量为1.04 GJ /年，18,106.8 m一年中每年³饮用水，7.396吨氢/年和3.838吨盐/年。系统的能量和火用效率分别等于12.25％和19.6％。该系统的投资回收期时间等于2.7年。
