Air Flow

 Alright, let's talk about the three rules or three laws of refrigeration. Rule one, airflow, rule two airflow. Take a guess at what rule three is. If you said airflow, you're right. Airflow. Airflow, airflow. A lot of people laugh and joke, can think, oh, that's pretty funny. But I, when I say that or when I teach that I'm being very serious.

Um, you have to have proper air flow in order to have refrigeration. Okay? Uh, if you wanna break down those three air flows. Uh, into categories. You have to have airflow throughout your apartment or your home. Um, off the, out of the evaporator, through the plenum, out through the duct work. You have to have airflow.

Okay, airflow number one. Are you getting air coming out of the vents? Do you have crushed duct work? Are the air damers closed? That are, are reducing airflow to a certain part of the house. These are all things that, that, that should be checked. The second airflow is airflow across the evaporator coil.

Does the resident have a clean filter? Is the coil clean? Is there an obstruction? Do they have a plant, a dresser, a mirror? Whatever it is, you guys know, you see it. Um, there. You know, they see those louver doors in the kitchens and they think, oh, this is ugly. Let me put this big giant potted plant right next to it.

Right? That restricts airflow. So airflow number two was across the evaporator, uh, airflow. Number three is airflow. Outside at your condenser, what do landscapers and, uh, property developers plant around all of those condensers outside? Those damn holly bushes, right, that restrict airflow because those condensers are pulling air from the ambient air from outside around through the coil to disperse the heat and get it up out of the way.

So you have to have clean coils, you have to have ways for air to get through those so that it can dispel the heat. So, airflow, airflow, airflow.
