I'm hoping this is a relatively simple question to answer, but I just couldn't find it on Google.
With regard to air conditioning (or any cooling system that relies on compressing/evaporating), how do you actually control the 'cooling' temperature? After compressing/pressurizing the refrigerant, I understand that it becomes cool due to releasing heat, however, how do you control the level of coolness?
Is temperature directly related the amount of pressure being applied to the refrigerant? I.e, more pressure leads to lower temperature, less pressure leads to higher temperature?
