Corrosion of copper tubes in the evaporator of the air conditioning unit
Thread Content
After opening the cover of the air conditioning unit, I noticed that the copper tubes of the evaporator were very shiny; is there any sign of copper corrosion? What is the cause?
Is this air conditioner a lithium bromide unit?
It’s not a lithium bromide unit; it’s a Carrier screw compressor.
You’re overthinking it; it looks fine on the surface, no problems at all:victory:
The surface color is that of normal use; if corrosion occurs, oxides should be present, with copper oxide generally appearing blue in color.
