Your vehicle isn’t equipped with a Clutch Cycling Orifice Tube AC system.
CCOT Systems
CCOT stands for Clutch Cycling Orifice Tube. This system is found on most low to middle class vehicles. This system has a fixed rate orifice tube and cycles the A/C clutch on the compressor to regulate pressures and refrigerant flow, as well as making sure the evaporator doesn’t ice up.
It uses an expansion valve to regulate the pressures.
From what you describe, it sounds like the system is low on refrigerant
