Question: 1 / 400

What will happen if a TEV sensing bulb becomes detached from the suction line?

High suction pressure and high discharge pressure

If a TEV (Thermostatic Expansion Valve) sensing bulb becomes detached from the suction line, it will result in high suction pressure and high discharge pressure. This is because the TEV is no longer able to sense the temperature of the refrigerant in the evaporator properly. As a result, the valve will not regulate the flow of refrigerant correctly, leading to an overfeeding of refrigerant into the evaporator. This causes an increase in both the suction and discharge pressures in the system, which can impact the overall performance and efficiency of the air conditioning system.

The other options are incorrect because they do not accurately describe the consequences of a detached TEV sensing bulb.
