The paper offers an assessment of the use of ammonia as a refrigerant gas and the trends of increasing its generalization for the coming years, especially in the industrial sector; The thermodynamic qualities of the gas are exposed; Their chemical properties; Their preferred use in industrial refrigeration was described; The impacts and risks associated with their use; It was evaluated a possible solution that can promote the reduction of the risk of pollution to the people in case of a massive escape of NH3 in the Company "La Isabel Ecuatoriana" SA and its surroundings.

It is known that approximately 15% of the energy consumed in Ecuador is used for the operation of climate conditioning equipment and, on the other hand, most of the existing technology operates on the basis of the use of refrigerant gases Are invasive to the ozone layer. In the work, a case study is shown that allows the identification of a relevant result linked to an action of technological innovation based on the conversion of the R-22 gas by the R-290 gas, thus reducing the consumption of electric energy and reducing the Environmental inventory of the institution, achieving a better performance of the technology.
