Kevin Thompson video transcript – Filter Dryer (Training Video Transcript)
Hey guys, how you doing? I’m Kevin Thompson here at HVAC Technical Academy and I’m here with Mrs. Smith. Mrs. Smith has some questions for me about her filter dryer and she wanted to know exactly like what is a filter dryer? So, a filter dryer is a tool I would say that goes on your high side line that enables the flow of refrigerant to flow through the system. You have two types of filter dryers. Biflow, which this one is biflow. The flow goes both ways, or single flow as Miss Smith has.
00:00:41
Why do I have single flow and not a B flow? >> So, you have single flow because on this condenser, this condenser is a straight cool. A straight cool meaning it only has one flow and it doesn’t have a reversing valve. A heat pump is a system that normally uses a reversing valve and that one we would use a B flow on. Oh, because it goes both ways. >> It goes both ways. So when it turns to heat or when you turn the heat on, it reverses the process and goes back the other way.
00:01:08
Oh, >> yes, ma’am. So, >> so how would I know it’s bad? >> So, for testing to see if it’s bad, you would clamp your meters on both sides of this. And if the temperature split between if it’s not a split between three degrees, then it would be bad. If it flows and it’s regular temperature, it wouldn’t be bad. And normally, you can feel like through the line, you’ll be able to feel the difference in temperature.
00:01:40
Oh, >> yes. That’s a way you can test without a tool. >> That’s interesting. >> Yes, ma’am. Well, would that be all the questions you have, Mr. Smith? >> Yeah. I think that’s about it. Okay, well you heard from Miss Smith. Hopefully I taught you guys something and I see you guys in the next video.
