It sounds like need an R-134a pressure/temperature chart. Normally, the system is charged by evaporator pressure which usually equates to 40-45 degrees Fahrenheit temperature in the evaporator. The high pressure side of a R-134a system is dependent on the outside ambient temperature and other factors (like fan speed and speed of the traveling car). For a better understanding of the pressure/temperature relationship of gasses look up Boyle's Law on Wikipedia.
You need to put more info into your question. There is no way to understand what it is you want.
yeah
Ary OK ???
