My guess is that when ambient temperatures are hot (85 to 100), the expansion valve and oil filled tube control for diverting the refrigerant directly to the compressor is sufficient. When temperatures are on the cool side (50 to 70) the mechanical system needs the help of the TCA. This a/c is way too complicated. I have no idea why R12 systems had the "throttle control valve". Is the TCA exclusive to R134a systems?
