Abstract
Se describe un aparato para proporcionar control integrado de un sistema de enfriamiento de espacio (20). El aparato recibe entradas desde una pluralidad de sensores de temperatura, incluyendo un medio sensible de temperatura para medir sobre calentamiento del evaporador (29, 28), temperatura de espacio (31) y temperatura de descarga del compresor. El aparato de control ajusta incrementadamente la posicion de la válvula de expansion del sistema de enfriamiento para regular el sobrecalentamiento del evaporador y la temperatura de descarga del compresor y regula el encendido y apagado del ventilador del condensador externo (27) para elevar la presion del condensador en respuesta a la condicion de presion baja del condensador. En una modalidad, el sistema de enfriamiento incluye una pluralidad de evaporadores (21) y una pluralidad de controladores (25) correspondientes, interconectados eléctricamente en un circuito en serie para controlar las válvulas de expansion (24) y los calentadores del descongelamiento (34) asociados con los evaporadores respectivos (21). Uno de los controladores funciona como un controlador maestro y recibe entradas desde el medio sensitivo de temperatura de espacio (31) y el medio sensitivo de temperatura de descarga del compresor (30) así como también desde los medios sensitivos de temperatura (28, 33, 29) asociados con el evaporador correspondiente (21).
