Condenser fan airflow direction??


Hey everyone,

I may sound stupid or like a novice by saying this but I was looking at my walk in cooler tonight and realize that the condenser fan is actually pulling the air thru the condenser. Why is that?

I would think that the condenser fan would have more cooling power by pushing the air thru the condenser.

What do you think?

is it normal for the fan to pull the air thru the condenser?

Which one do you think is best? pulling or pushing the air thru the condenser?

Thanks

Pulling. Better distribution and removal of heat and the entire condenser gets some benefit from it.

The best way to clean that is to shut it off drape wet towels over the condenser and blow high pressure air back through the coils, wow look at that dirt.

The only units that push air through a coil are gas furnaces with the cooling coil on top, and some True reach-in boxes.
Of course there are units where the tech puts the blade on backwards or installs the wrong motor..but that doesn't count

alright i got it. Pulling is better but i am still not convince about all the crap it sucking in the condenser. I mean i understand that it benefits the rest of the equipment by giving it air but wow!! anything that goes by the condenser gets sucked in. poor spiders lol

anything that goes by the condenser gets sucked anyway.......from outside to inside ( normal way ) or from inside to outside ( some old system )..........you just need coil cleaner to fix this problem.
