Chapter 55, Problem 5ASRQ

Technician A says that air in the system can cause excessive pressure within the system, restricting the refrigerant’s ability to change its state from gas to liquid within the refrigeration cycle. Technician B says that moisture can cause freeze-up at the cap tube or expansion valve, which restricts refrigerant flow or blocks it completely. Who is correct?

  1. Technician A only

  • Technician B only
  • Both A and B

    A vehicle is having its water pump replaced. When the water pump is removed, severe corrosion is found on the water pump impeller, and inside the engine. Technician A states that the radiator cap may be overpressurizing the system. Technician B states that the vehicle may have been run with 100% water in the cooling system for some time. Who is correct? Select one: a. Technician A only b. Technician B only c. Both Technicians A and B d. Neither Technician A nor B
    The centrifugal compressor is used for refrigerants that require short displacement and high condensing pressure. True False
