Abstract

A refrigerant handling system that includes an air purge chamber and a refrigerant pump for directing refrigerant into the air purge chamber so that the refrigerant collects in liquid phase at a lower portion of the chamber while air and other non-condensibles collect in the vapor space at the upper portion of the chamber over the liquid refrigerant. A purge valve is connected to the upper portion of the chamber for automatically or manually purging air and other non-condensibles from the chamber. A refrigerant outlet is positioned at the lower portion of the chamber for drawing liquid phase refrigerant from the chamber. Desiccant adsorbent material is disposed in a canister connected to the upper portion of the air purge chamber for adsorbing refrigerant vapor in air passing through the canister. The desiccant adsorption material thus prevents venting of refrigerant vapor with non-condensibles from the air purge chamber.
