The present investigation is developed in the refrigeration industry, whose activity is the production and commercialization of the ice used mainly in the fishing industry. The development consists in evaluating and comparing the steam compression refrigeration system with intercooler and the steam compression refrigeration system with compressor scale system. These evaluations are intended to determine the COP in both systems through an energetic and exergetic analysis, as well as to reduce the freezing time of the ice without affecting its quality. Finally, a thermoeconomic evaluation of these systems will be carried out to allow the company to analyze the convenience in study, by reducing their production costs using their productive processes efficiently, providing quality products, and being competitive in the market. It is evident that when carrying out the evaluation of the refrigeration system with compressor scale system, it will be possible to increase the exergetic efficiency, reduce the irreversibilities and the destroyed exergy; Above all, the COP will be increased by 8.28%, which allows a reduction in ice freezing time by 22.25% or 3 h and 39 min. In addition to obtaining savings in electricity consumption equivalent to $8563.00 dollars in the next 12 months.
