What does "design pressure" primarily refer to in refrigeration systems?

Design pressure in refrigeration systems refers primarily to the maximum pressure that a system can safely operate at. This is a critical factor in the engineering and construction of refrigeration systems, as it ensures that all components are rated to withstand the pressures they may encounter during normal operation.

Understanding design pressure is essential for selecting materials and components that can handle the expected loads without failure. It plays a significant role in safety, as exceeding this pressure could lead to catastrophic failures, leaks, or system breakdowns.

While average pressure, startup pressure, and minimum evaporating pressure are all relevant to the operation of refrigeration systems, they do not encapsulate the concept of design pressure, which is specifically focused on the highest pressure allowable for safe system function. Recognizing this distinction helps in proper maintenance and compliance with safety standards in refrigeration work.
