What is the minimum design pressure for a refrigeration system?

The minimum design pressure for a refrigeration system is crucial for ensuring safety and efficiency in operation. A design pressure of 15 psig is generally accepted because it accounts for the necessary safety factors in the system. This pressure level helps prevent structural failure of components under expected operating conditions, as well as accommodates fluctuations in pressure that may occur during normal system operation.

Using a minimum design pressure of 15 psig ensures that the system can handle potential pressure surges and thermal expansion without risking leaks or ruptures. This is especially important in refrigeration systems where fluctuations can occur frequently due to the cooling cycle.

Understanding the appropriate design pressure is fundamental for compliance with industry standards and regulations, which mandate that refrigeration systems be built to endure specific pressures that are above typical operating conditions, thus providing an additional safety margin.
