Title:
SYSTEMS, EQUIPMENT AND METHODS FOR STABILIZING HYDROFLUOROOLEFINS IN REFRIGERANT SYSTEMS
Document Type and Number:
WIPO Patent Application WO/2023/229995
Kind Code:
A3
Abstract:
The present invention relates to system, equipment and methods for preparing and charging a refrigerant circuit with either (1) a fluoroolefin refrigerant compositions stabilized with an inhibitor agent which prevents or reduce oligomerization or polymerization of the fluoroolefin component of the composition or (2) a purified fluoroolefin refrigerant compositions by removing the inhibitor agent, and/or maintaining the integrity of fluoroolefin refrigerant compositions in refrigeration equipment by circulating the fluoroolefin refrigerant compositions in the refrigerant equipment through or more columns or devices to remove at least one of oxygen and oxygen containing contaminants, moisture/water, oligomerization/polymerization by-products.
