Abstract

Un sistema de refrigeración incluye un subenfriador configurado para proporcionar subenfriamiento para un refrigerante líquido que fluye a través de un primer lado del subenfriador al transferir calor desde el refrigerante líquido a un refrigerante gaseoso que fluye a través de un segundo lado del subenfriador; una válvula de expansión se localiza en una entrada del segundo lado del subenfriador y se configura para controlar un flujo del refrigerante gaseoso a través del segundo lado del subenfriador; un sensor de temperatura de gas y un sensor de presión de gas se configuran para medir una temperatura y presión del refrigerante gaseoso; un sensor de temperatura de líquido se configura para medir una temperatura del refrigerante líquido subenfriado. Un controlador se configura para calcular un sobrecalentamiento del refrigerante gaseoso con base en la temperatura medida y la presión medida del refrigerante gaseoso y puede comparar el sobrecalentamiento calculado con un umbral de sobrecalentamiento; si el sobrecalentamiento calculado es menor que el umbral de sobrecalentamiento, el controlador puede cerrar la válvula de expansión; si el sobrecalentamiento calculado es igual a o mayor que el umbral de sobrecalentamiento, el controlador puede operar la válvula de expansión utilizando una técnica de control de retroalimentación para impulsar la temperatura del refrigerante líquido subenfriado a un punto de ajuste de la temperatura del líquido subenfriado.
