ABSTRACT:
A purge arrangement for absorption refrigeration systems using a solution of lithium bromide as an absorbent and water as a refrigerant, and a heat transfer additive, such as octyl alcohol being added to and mixing with the lithium bromide solution. The purge arrangement includes means for automatically removing noncondensible gases or vapor from the system, said means including a vacuum pump connected to a receiver to draw noncondensible gases therefrom; automatic electrical control means for said vacuum pump; and an additive overflow conduit to prevent additive collecting in the storage receiver and to assure additive return flow into the solution conduit.
