Air conditioner is running constantly

I have W126 350SDL

As said it's running all time but I have heat inside the cabin. but rear vent blowing cold air. I noticed today when open hood to check fluids, and saw air conditioner pipe has frost. I put on eco mode and still frost there.
Is any relay ? Any idea?

Thanks
