Abstract: The present disclosure relates to a heating, ventilation, air conditioning, and refrigeration (HVAC&R) system (14) including a refrigerant loop and a purge system (80) configured to purge the HVAC&R system of non-condensable gases. The purge system includes a liquid pump (84) configured to draw a first refrigerant flow from an evaporator (38), a controllable expansion valve (86) configured to receive the first refrigerant flow from the liquid pump and reduce a temperature of the first refrigerant flow, and a purge heat exchanger (88), which includes a purge coil (108). The purge coil is configured to receive the first refrigerant flow from the controllable expansion valve, a chamber of the purge heat exchanger is configured to draw a mixture of the non-condensable gases and a second refrigerant flow from a condenser (34), and the purge heat exchanger is configured to separate the non-condensable gases from the second refrigerant flow utilizing the first refrigerant flow.
