That was for Yourfishman.
It means that the amount of heat added due to compression is equal to the amount of heat released due to expansion. (Example: 70 degree air at 0psi will be 90 degrees at time of compression at 2psi - 90 degree air at 2psi will cool to 70 degree air at 0psi) Those numbers are fictitious, but representative. Think of a gas bottle - when you vent it off quickly it frost up at the nozzle. That is due to the rapid expansion of the compressed gas. That expansion released energy in the form of heat.
All of that being said, does not account for any heat added by the pump itself. However, your own measurements confirm that the heat transfer is not into the water in the skimmer.
