Abstract

Un ciclo de refrigeración altamente fiable que tiene un refrigerante residual, que se diseña de manera que el aceite de máquina refrigerante no se estanque en el ciclo de refrigeración después de salir del compresor aunque el aceite de máquina refrigerante sea débilmente soluble en un refrigerante. Así, se puede evitar el agotamiento en el compresor. Además de eso, aunque el acumulador se saque del ciclo, también se puede evitar una gran cantidad de aspiración de vapor húmedo al compresor. Se ha previsto una sección de control para controlar la solubilidad del aceite saturado en un refrigerante líquido en el ciclo de refrigeración. La sección de control incluye un receptor y reguladores de flujo primero y segundo que se colocan antes y después, respectivamente, del receptor. Un refrigerante líquido residual que se obtiene en la circulación de un refrigerante se reserva en el receptor a alta temperatura de manera que se evite que el aceite de máquina refrigerante débilmente soluble se separé.
