If you read my previous post about sealed system basics , you know that understanding the thermodynamic states of refrigerants saturated, subcooled, and superheated is essential to sealed system troubleshooting. In that post, I explained these states in terms of a simple pressure-temperature table. While that keeps things simple, it doesn't really give you a strong visual and mental model for how the refrigeration cycle works thermodynamically. That's why we're going to spend this whole post learning how to read a P-H diagram. It takes a bit more work than just reading a P-T table, but this diagram is where those values on the P-T table come from , so learning to read it will give you a deeper understanding of what's going on in the sealed system. Pretty overwhelming, right? I remember how quickly my eyes started crossing when I first looked at one of these. This diagram conveys a ton of information, but some of it isn't really necessary for us techs, and the stuff that is useful gets lost in the jumble if you don't know what to look for. Let's strip this diagram down to something really simple, then start adding lines back in step by step. That's a bit more straightforward!

Once the refrigerant is a fully saturated liquid, any additional heat loss results in a decrease in temperature. SpotXchange sets this cookie as a unique ID that tracks audiences internally.
