OH 112: HVAC: Full Practice Exam #42
Q: For state two, why do we go straight out from the vapor saturation line until we hit our line of constant entropy? Since the problem states we are operating between zero and 80 degrees, why don't we follow 80 down as we leave the vapor saturation line?
A: So this was a refrigeration cycle problem. And the problem statement, I said that the cycle is 80 degrees Fahrenheit condensing, which was an interesting way to phrase it. And that's what is going to end up coming down to is phrasing.
