Two Concepts

1.The nature of AC is equilibrium.
It means through some technology to debug the air and humidity quality in a specify room, and to result in its stablity, people maitain the AC device according to the state parameter.
2.Enthalpy
It's a stand-in for energy in chemical system. It depends only on the final configuration of internal energy pressure and volume, not on the path taken to achieve it. It's the sum of its internal energy and the product of its pressure and volume. (quote from Wiki)
Enthalpy is an important parameter in HAVC, but I don't understand it. It is so sad.

Corrections

1. The nature of AC isal state of AC is in equilibrium. ItThis means that, through some technology to debug the air and humidity qualused to purify the air and control the humidity in a specifyic room, and to result in its stablity, people maintain the AC device according to the statendard parameters.

2.Enthalpy It' This is a stand-in for energy in a chemical system.

Not sure what this means.

It dependsis determined only onby the final configurationamounts of internal energy, pressure, and volume, not on the path taken to achieve ithe amount.

It's the sum of ithe chemical system's internal energy and the product of its pressure and volume.

Feedback

Nice! Are you looking to do something related to HVAC maintenance after teaching? I hear that kind of stuff pays pretty well.

No, my coming exam is about the HVAC, which I majored in during my college. I think the pay won't be bad, but it is really diffivlut for me, otherwise, I would have worked as an engineer.
