← ScienceWhich effect results when compressed liquid refrigerant flashes across an air conditioning TXV?
A)Rapid temperature drop because adiabatic expansion occurs✓
B)Increased turbulence prolongs refrigerant cooling time
C)Higher superheat reduces compressor oil return
D)Capacity reduction stabilizes evaporator saturation temperature
💡 Explanation
Rapid temperature drop results because the Joule-Thomson effect causes adiabatic expansion. Pressure reduction across the valve causes a phase change and sudden cooling, therefore efficient heat absorption occurs, rather than turbulence which would impede it.
