Question 159Refrigeration & AC - 1st Asst/Chief
70% to passOverfilling a refrigerant container is extremely dangerous because of the high pressures generated. The generation of pressure is the result of what?
Adischarge pressure from the recovery cylinder
Bvapor pressure of the refrigerant at saturation temperature
Chydrostatic pressure of the expanding liquid
Ddischarge pressure of the recovery compressor
AI Explanation
The correct answer is C) hydrostatic pressure of the expanding liquid. When a refrigerant container is overfilled, the expanding liquid refrigerant creates high hydrostatic pressure within the container. As the liquid refrigerant expands, it takes up more volume, resulting in a buildup of internal pressure. This high pressure can be extremely dangerous, as it increases the risk of the container rupturing or exploding. The other options are incorrect because they do not directly address the root cause of the pressure buildup, which is the expansion of the liquid refrigerant.
