| description | This paper presents the results of a case study carried out in a warehouse, and, in particular, the technical data obtained from field visits and a proposal for energy saving. The proposal entails incorporating a cogeneration system based on a motor generator (400 kWe ISO) to produce electrical energy, and an absorption cooling system (75 TR) that uses residual heat to generate air-conditioning. The absorption chiller consumed 54% less energy than the conventional air-conditioning system. Moreover, the produced energy can supply the plant’s total consumption, in addition to offering an excess of 57,312 kWh per month, which was reflected in the analysis of energy for sale to users with a high domestic consumption rate (DAC, for its Spanish acronym). The proposal’s total investment is USD 1,091,258, with a net monthly savings of USD 30,901, and an investment payback period of 2.9 years, which indicates the viability of this project according to its energy characteristics, notwithstanding that it is for a service provider company. |

Este trabajo es resultado de un estudio de caso realizado en una bodega. Se muestran en él los datos técnicos obtenidos a partir de la visita de campo y una propuesta energética. La propuesta consta de la incorporación de un sistema de cogeneración basado en un motogenerador (400 kWe ISO) para producir energía eléctrica y de un sistema de refrigeración por absorción (75 TR) que aproveche el calor residual para generar aire acondicionado. Se observó que el chiller de absorción consume 54 % menos energía que el sistema convencional de aire acondicionado empleado. Por otra parte, la energía producida abastece el total del consumo de la planta, además de ofrecer un excedente de 57,312 kWh por mes, el cual se tomó en el análisis como energía de venta a usuarios con tarifa doméstica de alto consumo (DAC). La inversión total de la propuesta es de 1 091 258 USD, con un ahorro neto mensual de 30 901 USD y un tiempo de recuperación de la inversión de 2.9 años, lo que indica la viabilidad de este proyecto de acuerdo con sus características energéticas, a pesar de tratarse de una empresa que brinda servicios.
