Understanding HVAC Superheat: Common Issues with Calculating Target Levels

[QUOTE="jelanier, post: 5508141, member: 433250"] Hard to explain in a few words, but I will try. When charging the A/C with refrigerant the idea is to maximize efficiency while also protecting against the possibility of liquid refrigerant in the return line. The conditions change with temperature. The target superheat is based on an existing condition which takes into account what will happen as conditions change. When the target superheat is known, the suction pressure (converted to temp 'boiling') is compared with the measured temperature of the return line. This is the superheat value to be adjusted to equal the target value previously calculated. Your response is exactly why I ask the question. The indoor wetbulb measurement depends on indoor return temperature and humidity of the indoor air. The ambient is the air temperature entering the condenser outdoors. The systems are obviously related. I am trying to understand the "limit" that I came across. (Oh, I am not trying to do anything. I have already done it. I did it under conditions that were not mathematically problematic) Thanks [/QUOTE]
