Abstract

Dispositivo de descongelación para un frigoríficocuyo termostato de evaporador tiene un contacto para la desconexión del compresor a una temperatura de desconexión y para la conexión a una temperatura de conexión más elevadacon un regulador cronológico de descongelaciónque al responder o reaccionar ponga en acción a un dispositivo de conmutaciónque reprima la conexión del compresor hasta alcanzarse una temperatura de conexión y eventualmente conecte un dispositivo calefactor de descongelacióncaracterizado porque el termostato de evaporador tiene un contacto de salto elástico con histéresis de conmutación y un elemento de accionamiento de contactoque es cargado por un elemento de trabajo que ejerce una fuerza dependiente de la temperaturapor un resorte principal que actúa en sentido opuestoporque el dispositivo de conmutación puesto en acción suprime el cierre de fuerzas entre el resorte diferencial y el elemento de accionamientoy porque el resorte principal está dimensionado de modo tal que con su sola acción se efectúe la conexión del contacto a la temperatura de descongelación.
