Disclosed is a method of anodizing the interior surface of a heat transfer tube comprising placing a plurality of contact electrodes in electrical communication with, and along, an exterior surface of the heat transfer tube, inserting a counter electrode into an interior space of the heat transfer tube, providing an electrolytic solution to the interior space of the heat transfer tube, passing an electric current between the plurality of contact electrodes and the counter electrode through the electrolytic solution, forming an oxidation layer along the interior surface of the heat transfer tube, wherein the oxidation layer has an oxidation layer thickness that decreases along a length of the heat transfer tube, stopping the passage of the electric current, removing the electrolytic solution, and applying a sealing solution to a surface of the oxidation layer to form a sealed oxidation layer along the interior surface of the heat transfer tube.

Methods of anodizing the internal surface of heat transfer tubes

A corrosion protection system is provided. The corrosion protection system comprises an electrical contact coupled to an apparatus. The electrical contact can apply a negative potential to the apparatus. The corrosion protection system comprises a sensor. The sensor detects moisture with respect to the apparatus. The corrosion protection system comprises a power supply. The power supply is electrically coupled to the electrical contact and provides a negative potential to the electrical contact in accordance with commands of a processor. The processor utilizes the power supply attached to the apparatus via the electrical contact to provide and apply the negative potential to the apparatus based on a sensor signal from the sensor. The sensor signal indicates the detection of the moisture by the sensor.

Corrosion protection system for heating ventalation air conditioning refrigeration

A method and system of activating a fan for an air conditioning system is disclosed. Upon the sensing of rain in the proximity of the air conditioning system, such as a condenser, a fan is activated. The fan is configured to drive air and rain through the condenser. The fan can be configured to operate periodically or for a pre-set amount of time while rain is being sensed.
