Condensing Unit

 So we've learned how important airflow is. We've learned what happens at our evaporator, but now let's talk about what happens outside of the condenser. It's literally the same thing, airflow. Okay? The third airflow, you have your condenser outside. You have all of that heat that was picked up inside in the refrigerant.

You have all of that heat in that refrigerant. Now moving outside. Okay, so once it hits the compressor, it leaves the compressor, the, the compressor, uh, outside takes a low pressure, low temperature refrigerant and converts it into a high temperature, high pressure refrigerant. So that's why you get the, the cold lines and the hotlines.

Um. It's not how I'm typically refer to it, but let's just use that cold line hotline, low line, high line suction line, high pressure line. So you've got all of that heat running through the condensing coil. You've got a fan that's spinning, that's taking heat, taking airflow from outside, pulling it through the coil and shooting it out the top.

So that's why when you put your hand across the top, it should be hotter. Than the ambient air around you. Okay, so the ambient temperature, the ambient air that is at a less temperature or a lower temperature than the, the, the coil temperature, that cold air, cooler air is going to hit that heat. 'cause remember, cold absorbs heat, yes, it's gonna hit, that cooler air is gonna hit those hot.

Uh. Uh, that hot, uh, condensing coil lines, and it's gonna absorb the heat from those lines, and then it's gonna be redistributed right out the top. Okay? So that's why it's very important to make sure that your coils are clean outside, because you have to have proper airflow come through those coils to get the heat out.

That will then take it out the top. Okay? Clogged coils inside at the evaporator will result in low pressure, clogged coils outside will result in high pressure. Okay, so make sure your coils are clean.
