Refrigeration Plant Operator B 2025 – 400 Free Practice Questions to Pass the Exam

Question: 1 / 400

What happens when ammonia absorbs enough heat in a hydrostatic condition?

It loses cooling capacity

An explosion may occur

When ammonia absorbs enough heat in a hydrostatic condition, the process can lead to a significant increase in pressure within the system. If this pressure surpasses the design limits of the equipment or components in the refrigeration system, it could create a dangerous situation, potentially resulting in an explosion. This risk is heightened in a hydrostatic condition because of the trapped nature of the liquid, which does not allow for the expansion or normal escape of gases that typically regulates pressure in a refrigeration system.

Understanding how ammonia behaves under thermal conditions is crucial for operators. High pressure from heat absorption within a closed system can lead to catastrophic failure if not managed correctly, emphasizing the importance of maintaining safe operating parameters within ammonia refrigeration systems to prevent such hazardous scenarios.
