Abstract: The present disclosure relates to a purge system for a vapor compression system including an emission canister. The emission canister includes a load cell disposed in an interior of the emission canister, a base supported by the load cell, and an adsorbent material disposed on the base. The adsorbent material is configured to adsorb a refrigerant flowing through the emission canister, and the load cell is configured to monitor a weight of the adsorbent material and the refrigerant within the emission canister.

Abstract: The present disclosure relates to a purge system for a vapor compression system, where the purge system includes an emission canister configured to receive a gas flow. The gas flow includes a mixture of non-condensable gases and refrigerant of the vapor compression system. An adsorbent material is disposed within the emission canister and configured to adsorb the refrigerant and enable the non-condensable gases to flow toward an exhaust of the emission canister, where the adsorbent material is a silica gel.

Abstract: 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.

Abstract: Embodiments of the present disclosure relate to a heating, ventilation, air conditioning, and refrigeration (HVAC&R) system having a purge system configured to purge a vapor compression system of non-condensable gases (NCG). The purge system includes a refrigerant loop configured to circulate a purge refrigerant and a purge heat exchanger configured to place the purge refrigerant in a heat exchange relationship with a mixture of vapor refrigerant and NCG received from the vapor compression system. The purge system further includes a pump configured to draw the mixture from the vapor compression system, increase a pressure of the mixture, and deliver the mixture to the purge heat exchanger. The pump is disposed upstream of the purge heat exchanger, relative to a flow path of the mixture from the vapor compression system to the purge heat exchanger.

Abstract: In an embodiment of the present disclosure, a heating, ventilation, and air conditioning (HVAC) system includes a refrigerant loop configured to flow a refrigerant and a purge system configured to purge the HVAC system of non-condensable gases (NCG). The purge system includes a purge heat exchanger configured to receive a mixture of the NCG and the refrigerant. The purge heat exchanger is configured to separate the NCG of the mixture from the refrigerant of the mixture utilizing a chilled fluid. The purge system also includes a thermoelectric assembly configured to remove heat from the chilled fluid.
