Question 97Refrigeration & AC - QMED

The correct answer is A) hydrostatic pressure of the expanding liquid. Overfilling a refrigerant container leads to an increase in the hydrostatic pressure of the expanding liquid refrigerant. As the liquid refrigerant expands to fill the available space, the pressure inside the container rises dramatically due to the incompressible nature of the liquid. This high pressure can cause the container to rupture, which is extremely dangerous. The other answer choices are incorrect because they do not directly explain the cause of the high pressure generation. Vapor pressure, discharge pressure from the recovery cylinder, and discharge pressure of the recovery compressor are not the primary reasons for the dangerous pressure increase in an overfilled refrigerant container.
