Obtidos experimentalmente os pontos das curvas de temperatura no evaporador, congelador e gabinete de refrigeração, determinam-se os coeficientes das funções de transferência que, devidamente aplicados às equações diferenciais de 2° ordem, permite simular o comportamento térmico de um refrigerador doméstico de forma simples e rápida. / In this paper the mathematical modeling of the thermal behavior of a domestic refrigerator is proposed through transfer functions, using the analogy of a thermal system converted for a simplified electric system. Obtained the points of the curves of temperature of the evaporator, freezer and internal compartment experimentally, they are determined the coefficients of the transfer functions that, properly applied to the second-order differential equation, it allows to simulate the thermal behavior of a domestic refrigerator in a simple and fast way.
