In this project we study the energy efficiency of different types of utensils used in liquefied gas cookers and induction cookers. In the study, tests are carried out on three different types of pots commonly marketed in the Ecuadorian market: stainless steel pots, aluminum with a stainless steel Incrustation and Aluminum coated with steel and stainless steel by metallization. Each of the samples is evaluated considering a balance of energy and factors that can affect the efficiency of energy transfer, these factors are: thermal stresses and deformations of the base (convexity of the base), difference of thermal expansion of the materials and thermal gradients in the utensil during cooking...En el presente proyecto se estudia la eficiencia energética de distintos tipos de utensilios usados en cocinas a gas licuado y en cocinas de inducción. En el estudio se realiza ensayos en tres diferentes tipos de ollas comúnmente comercializados en el mercado ecuatoriano: ollas de acero inoxidable, ollas de aluminio con base de incrustación de acero inoxidable, y ollas de aluminio con base de metalización de acero...
