A bidirectional filter drier has a generally spherical outer shell having a first opening and a second opening. The shell contains a desiccant core and first and second filter elements. The first filter element is on a first side of the core, adjacent the first opening, and the filter flexible element on a second side of the core adjacent the second opening. The first filter element and the second filter element control flow around and through the core depending on the direction of fluid flow through the filter drier.

The present disclosure relates to a purge system for a vapor compression system including an emission canister having an adsorbent material disposed therein. The purge system also includes a heating system configured to transfer thermal energy to the adsorbent material, where the heating system includes a first heating element and a second heating element disposed within the emission canister and extending along a central axis of the emission canister. The first heating element and the second heating element are configured to distribute the thermal energy transferred to the adsorbent material disposed within the emission canister to release refrigerant from the adsorbent material.
