Abstract
A refrigerant reclaim system including an automatic air purge system. The refrigerant reclaim system has an evaporator, oil separator, compressor, condenser, storage tank, and a filter-drier. An improvement relates to an automatic air purge system having an evaporator to concentrate noncondensable gases in an isolated area of the refrigerant reclaim system so as to minimize the loss of refrigerant vapor during purge operations. The air purge system is not limited to use with a refrigerant reclaim, and is suitable for use with any refrigeration system from which noncondensable gases are to be purged with minimal loss of refrigerant vapor.
