First Claim
Patent Images
1. A packaged terminal air conditioner unit, comprising:
- an outdoor heat exchanger disposed in an outdoor portion;
an indoor heat exchanger disposed in an indoor portion;
a bulkhead disposed between the outdoor heat exchanger and the indoor heat exchanger along a transverse direction, the bulkhead defining the indoor portion and the outdoor portion;
a drain pan defining a reservoir for collecting condensate from the indoor heat exchanger and the outdoor heat exchanger;
a corrosion inhibitor module comprising a module housing positioned within the reservoir and defining an inlet and an outlet, and a corrosion inhibitor concentrate positioned within the module housing;
an intake conduit providing fluid communication between the reservoir and the inlet of the module housing; and
a circulation pump operatively coupled to the intake conduit for urging a flow of condensate from the reservoir and into the module housing, the flow of condensate mixing with the corrosion inhibitor concentrate to form an inhibitor solution that flows back into the reservoir through the outlet.

Abstract
A corrosion inhibitor module for a packaged terminal air conditioner unit (PTAC) is provided. Condensate is pumped from a drain pan of the PTAC into a housing of the corrosion inhibitor module. The housing contains a corrosion inhibitor concentrate that is mixes with the condensate to form an inhibitor solution that is returned to the drain pan to prevent the corrosion of components that come in contact with the condensate.
