May–June Session
Hello, my name is Greyson and today I’m going to be showing you how the filter dryer works, where it’s located, and why it’s needed.
The filter dryer is located near the condenser on the liquid line.
And basically what it does is the refrigerant goes through the liquid line and then goes through the filter dryer. The filter dryer gets rid of all the contaminants and all the moisture in the refrigerant, which is needed to happen.
And basically that’s pretty much all the filter dryer does.
But there’s two different types of filter dryers. There’s a bi-flow and a single-flow.
So, to tell if it’s bad, you can kind of just feel on both sides here. You can see if there’s a temperature drop or whatever.
And then if there’s any blockage signs as well.
And yeah, it’s needed to keep the refrigerant clean.
And yeah, that’s the filter dryer.
