If the thermal bulb assembly develops a leak, what will occur?
A) All of the system's refrigerant will leak out.
B) The bulb pressure will reduce and the valve will close.
C) The valve will open to allow more refrigerant to flow.
D) It will have no effect on system operation.

Question

Quizplus · Accepted Answer

The thermal bulb is an integral part of the expansion valve and is responsible for regulating the flow of refrigerant into the evaporator. If the bulb assembly develops a leak, it will result in a reduction of pressure inside the bulb, causing the valve to close and limit the flow of refrigerant. This will ultimately lead to a decrease in system performance and potential system failure. Therefore, option B is the correct answer.
