The design pressure for a refrigeration system should be high enough to avoid what?

The design pressure for a refrigeration system is crucial in ensuring the system operates effectively and safely. A primary purpose of maintaining an appropriate design pressure is to avoid nuisance shutdowns. Nuisance shutdowns can occur when the pressure drops below the system's designed operational range. This can lead to unreliable operation and unnecessary interruptions, adversely affecting the performance of the refrigeration system.

A properly set design pressure helps maintain system stability under various operating conditions. Nuisance shutdowns not only disrupt cooling processes but can also cause increased wear and tear on components and lead to more frequent service calls. Therefore, selecting a design pressure that is high enough to maintain consistent operational performance ensures that the system remains efficient and functional without unnecessary interruptions. This highlights the importance of considering design pressure in the operational integrity of refrigeration systems.
