Se evalúa la factibilidad técnica y económica del uso de un ciclo binario del tipo ORC para la generación de electricidad, a partir del aprovechamiento del recurso geotérmico de baja temperatura disponible en varios campos de petróleo en Colombia. Las temperaturas del agua obtenida como subproducto durante la extracción de crudo son 118 ºC en boca de pozo y 82 ºC en etapas de disposición, con caudales de hasta 2,38 m3/s. Para incrementar la eficiencia del ciclo convencional, fueron evaluadas alternativas de calentamiento de la corriente del lado de alta temperatura y de enfriamiento del lado de baja temperatura. Se encontró que un equipo comercial ORC de 280 kW  produciría en uno de los campos 1.165,1 MWh anuales  con un costo de generación de 0,102 U$/KWh. Los resultados de este estudio no permiten la implementación de equipos ORC porque se requieren mayores temperaturas que garanticen la factibilidad técnica.Abstract: These paper analyze the technical and economic feasibility of generating electricity from low temperature geothermal resources available in oil oilfields in Colombia using binary ORC technology. The water obtained as a byproduct during oil extraction has 118°C temperatures at wellhead and 80ºC on average in disposal stages; the water flow rates reach values of 2.38 m3/s. Were studied to improve the efficiency, technical options for additional heating and cooling of hot and cold streams.  According to the results found, 1.165,1 MWh energy production by year and 0,102 U$/KWh in unitary generation cost is for the 280 kW commercial ORC machine. According to the experience developed in this study results do not permit ORC immediate implementation because are necessary higher temperatures to guarantee technical feasibility.Sumário: A viabilidade técnica e econômica da utilização de um ciclo ORC binário para geração de eletricidade a partir da utilização de recursos geotérmicos de baixa temperatura disponíveis em vários campos de petróleo na Colômbia é avaliada. As temperaturas da água obtida como um subproduto durante a extração de petróleo cru são 118 ºC na boca de poço e 82 ºC em fases de distribuição, com vazões de até 2,38 m3/s. Para aumentar a eficiência do ciclo convencional, foram avaliadas (várias) opções de aquecimento da corrente de alta temperatura e de esfriamento do lado de baixa temperatura. Verificou-se que um equipamento comercial ORC de 280 kW poderia gerar em um dos campos 1165,1 MWh anuais a um custo de 0,102 U$/kWh. Estes resultados não permitem a implementação de equipamentos ORC porque precisam-se temperaturas mais altas para assegurar a viabilidade técnica.

Wastewater is an abundant and an underutilized thermal energy source that experiences steady temperatures and predictable flow rates year-round. These characteristics make it an excellent candidate to serve as the heat source and sink for heat pump based HVAC (Heating, Ventilation, and Air Conditioning) systems capable of providing both heating and cooling. The potential for wastewater heat recovery is evaluated for a large hospital in the greater Toronto area, in Canada. A model was developed to calculate the operational savings and benefits of the proposed system, and the results from that analysis were used to carry out an economic analysis.

The study presented in this paper assessed the multidisciplinary approach of geothermal potential in the area of the most southeastern part of the Pannonian basin, focused on resources utilization. This study aims to present a method for the cascade use of geothermal energy as a source of thermal energy for space heating and cooling and as a resource for balneological purposes. Two particular sites were selected—one in a natural environment; the other within a small settlement. Geothermal resources come from different types of reservoirs having different temperatures and chemical compositions. At the first site, a geothermal spring with a temperature of 20.5 °C is considered for heat pump utilization, while at the second site, a geothermal well with a temperature of 54 °C is suitable for direct use. The calculated thermal power, which can be obtained from geothermal energy is in the range of 300 to 950 kW. The development concept was proposed with an architectural design to enable sustainable energy efficient development of wellness and spa/medical facilities that can be supported by local authorities. The resulting energy heating needs for different scenarios were 16–105 kW, which can be met in full by the use of geothermal energy.
