Description

ABSTRACT:
Thermal purge apparatus for a chiller removes air, moisture and other non-condensibles from the chiller system refrigerant by causing chiller system refrigerant vapor to condense in a purge tank as a result of its undergoing a heat exchange relationship with a second and different refrigerant employed in a discrete purge refrigeration circuit. Chiller refrigerant circulates from the chiller condenser to, through and out of the purge tank in a free-flowing circulatory manner as a result of temperature and pressure gradients which develop between the interiors of the chiller condenser and the purge tank when the purge apparatus is in operation.
