Abstract

Un aparato infriador/congelador, auto-contenido, para llevar productos en un ambiente congelado o refrigerado. El aparato comprende un contenedor aislado, el cual se divide en dos porciones. La primera porción es aquélla donde se almacenan los productos. La segunda porción aloja un compartimiento del refrigerante para almacenar un refrigerante sólido, es decir el dióxido de carbono sólido o el hielo seco. En un período de tiempo corto, el hielo seco comienza a sublimarse, formado así dióxido de carbono gaseoso frió, el cual llena el volumen del aparato. Se usa un ventilador para circular el dióxido de carbono en todo el contenedor aislado, removiendo así el calor desde la primera porción y rechazándolo al hielo seco en el compartimiento del refrigerante, enfriando así la primera porción del contenedor aislado. El dióxido de carbono gaseoso frió es circulado en todo el contenedor aislado por medio de conductos de gas colocados dentro de las paredes del contenedor aislado. Un controlador termostático acciona el ventilador con base en las lecturas de temperatura desde los pares térmicos colocados dentro de la primera porción del contenedor aislado. Una válvula de alivio de presión se coloca dentro del contenedor aislado, para impedir que la presión, dentro de este contenedor aislado, se acumule más allá de un valor máximo.A self-contained cooler / freezer to carry products in a frozen or refrigerated environment. The apparatus comprises an insulated container, which is divided into two parts. The first portion is that where the products are stored. The second portion houses a refrigerant compartment to store a solid refrigerant, that is, solid carbon dioxide or dry ice. In a short period of time, the dry ice begins to sublimate, thus forming cold gaseous carbon dioxide, which fills the volume of the apparatus. A fan is used to circulate carbon dioxide throughout the insulated container, thereby removing heat from the first portion and rejecting it to dry ice in the refrigerant compartment, thereby cooling the first portion of the insulated container. The cold gaseous carbon dioxide is circulated throughout the insulated container by means of gas lines placed within the walls of the insulated container. A thermostatic controller operates the fan based on temperature readings from the thermal pairs placed within the first portion of the insulated container. A pressure relief valve is placed inside the insulated container, to prevent pressure, within this insulated container, from building up beyond a maximum value.
