Abstract
A chemical state monitoring system for a refrigeration system that continuously monitors and detects problems within a refrigeration system. The monitoring system comprises a sampling device for collecting refrigerant in a high pressure liquid line of the refrigeration system, a purge valve in an upper portion of the sampling device; a refrigerant state sensor for sensing a condition indicative of the state of refrigerant in the collection chamber; and a controller operatively connected to the refrigerant state sensor and to the purge valve for controlling said purge valve and detecting fault conditions based on signals from the sensor.
