I How is target superheat table generated for R22 HVAC system

Click For Summary
The discussion focuses on the use of evaporator air intake wetbulb temperature and condenser ambient temperature to determine the appropriate target superheat in HVAC systems. Participants are seeking clarification on the theoretical basis for translating these temperature readings into superheat targets. The conversation references an article that outlines troubleshooting HVAC systems using superheat measurements but emphasizes the need for understanding the generation of the related tables. The inquiry highlights a gap in knowledge regarding the underlying principles of superheat calculation. Understanding these concepts is essential for effective HVAC troubleshooting and system optimization.

It seems the practice is to enter the table with evaporator air intake wetbulb temp and condenser ambient temp. I'm trying to understand the theory that translates these readings into the proper target superheat.

Thanks

Yes, I'm somewhat familiar with that article... the question is, how is the table generated?

Plotted is the Irradiance over Wavelength. Please check for logarithmic scaling. As you can see, there are 4 curves. Blue AM 0 as measured yellow Planck for 5777 K green Planck for, 5777 K after free space expansion red Planck for 1.000.000 K To me the idea of a gamma-Ray-source on earth, below the magnetic field, which protects life on earth from solar radiation, in an intensity, which is way way way outer hand, makes no sense to me. If they really get these high temperatures realized in...
