Abstract

La presente invencion se relaciona con un sistema de refrigeracion en cascada para hacer circular un refrigerante que comprende una fluoroolefina. El sistema de refrigeracion en cascada incluye un circuito de refrigeracion de temperatura baja y un circuito de refrigeracion de temperatura media. La fluoroolefina circula a través de cualquiera de los circuitos o en ambos. En una modalidad en particular, la fluoroolefina circula a través del circuito de temperatura media. En una modalidad en particular, en donde el sistema de refrigeracion en cascada incluye un primer y segundo intercambiador de calor en cascada y un circuito secundario de transferencia de calor que se extiende entre el primer y el segundo intercambiador de calor en cascada, el primer y/o el segundo refrigerante puede ser, pero no necesariamente es una fluoroolefina.The present invention relates to a cascade refrigeration system for circulating a refrigerant comprising a fluoroolefin. The cascade cooling system includes a low temperature refrigeration circuit and a medium temperature refrigeration circuit. Fluoroolefin circulates through either circuit or both. In a particular embodiment, fluoroolefin circulates through the medium temperature circuit. In a particular embodiment, where the cascade cooling system includes a first and second cascade heat exchanger and a secondary heat transfer circuit that extends between the first and second cascade heat exchanger, the first and / or the second refrigerant may be, but is not necessarily a fluoroolefin.
