Cooler air holds less moisture than warmer air. So like TG said, when warm air is let in, it cools because of the air conditioning and all of that moisture comes out in the form of humidity.

The colder you make the air, the more humidity is released; so on a hot day if you dropped the temperature in staples by 10 degrees, you would actually end up with more humidity than if it is warmer. This is the reason all air conditioners are equipped with some kind of dehumidification unit.

For good ice, you would need to have super efficient dehumidification in an area like LA. The air has a lot of moisture as it is and cooling just makes it worse. This isn't always feasible because of very high costs and the fact that the doors are open often. Outside of buying huge dehumidifiers that could quickly circulate a large volume of air, there's only so much that can be done.

One idea would be to put glass/plexiglass sliders on as many entrances to the seating area as possible. If these are closed prior to the game, it would minimize the amount of warm humid air entering. They could be open in times of heavy traffic, but closed the rest of the time. The downside is you need someone to man them, drunk fans and the potential for accidents, and so on. It would be a substantial cost, but would be highly effective.
Maybe some of these bad boys - put them in the tunnels as close to the ice surface as possible, where you already have personnel manning the tunnel exit to the concourses:
