yes ...existing records will be deleted...... as Sonam suggested back up your data in .CSV and reimport after sandbox refresh.

When you do a refresh - production ORG gets copied over to the sandbox and all changes get deleted from the sandbox so I will suggest you back up the important data you have in developer sandbox and then do a refresh.

 

Note: A sandbox refresh deletes and recreates the sandbox as a new copy of the production organization.
