The cache replacement policy tells in which order Squid evicts entries
from the cache to make room for new objects.
the refresh algorithm tells how Squid determines if the object it has in
the cache is fresh or if the origin server needs to be consulted before
sending the reply to the client.
The two have different purposes. The replacement policy makes sure there
is space in the cache by thowing away uninteresting objects, the refresh
algorithm makes sure the client gets up to date content.
