What will be an ideal response?
During an AC performance test, an R-134a air conditioning system has a measured center duct outlet temperature of 41 degrees F. The manifold gage set shows low side pressure between 21-35 psi. The high side pressure ranges from 175-210psi. Intermittantly, the duct outlet temperature will rise to 60 degrees F and the low side gage show a vacuum when this happens. Shop Temperature is 72 degrees F. What is most likely the cause?
a. The system contains moisture causing a restriction in the TXV b. The system contains air with the refrigerant c. The TXV is defective and allowing too much refrigerant to flow d. The system is operating normally
