A method of lubricating an interior of a tube includes applying a lubricant including a mixture of an additive and a solvent into an interior of a tube. A flow of drying agent is injected into a first end of the tube to force the solvent from the interior of the tube via a second end of the tube thereby leaving a coating of additive at the interior of the tube. The drying agent is heated to remove additional solvent from the interior of the tube via evaporation.

Method for lubricating interior of heat exchanger tube

A brazing ring is provided and includes ring material including an aluminum-zinc-silicon alloy having a first melting point and flux material contained within the ring material having a second melting point, which is substantially lower than the first melting point, the ring material being formed such that the flux material is exposed outwardly to a heat source and such that, upon heating, flux material melts before the ring material.

Brazing ring

A comfort system outdoor unit with a heat exchanger coil and a fan in its top opening has an orifice structure and an insert registerable with the orifice structure to streamline the inward flow of air that passes over a lower end of the orifice structure. The insert may be fastened directly to the orifice structure lower end, or it may be installed so as to extend substantially from an upper edge of the coil to the orifice structure lower end.

Streamlined orifice of outdoor unit

A coil support suitable for supporting a coil in a condensing unit includes a body and a protrusion extending from the body. The protrusion is configured to limit movement of the coil in at least one direction.
