How Do Portable Air Conditioners Drain?
How do portable air conditioners drain?
Answer:
They have evaporator pan plus they also have a drip hole drain on the back at the bottom which you need to check on occasion because they do clog up. I'm pretty sure the portable type has an evaporator fan that dries up the moisture as it runs...just like a refrigerator.This is if you are talking about a true "portable" a/c...the type you can set anywhere like floor, table,etc...if you are talking about a window unit then these other folks are correct. The portable air conditioner has a drip tube. I use a small sump pump with a built in tank to have the water pumped outside through a small hole I drilled in the window plate where the condenser air blows outside. I bought the condensate pump from e-bay for about $25.00 Some window conditioners drain into the built in "pan", & the fan picks up the moisture & uses it to cool the coil. Some have a drain tube, & need a place to drain without damaging the woodworks. Make sure that there is a little slant downward, as I have seen them not drain correctly and the moisture rots the window sill.
