That is the valve cover and the red substances seems to be sealants. I don't see how sealants could be dripping.
Under normal circumstances, sealants are not used as the valve cover gasket is a rubberised seal and is compressed to prevent leakages.
The compressor is the component at lowest point of engine at front part where it has a belt going over it.
When A/C is turned ON, the outer part should click and attache itself to work.
