Every air conditioning or refrigeration system should be protected by which device?

Overpressure protection is essential in any air conditioning or refrigeration system. A pressure relief device is designed to open when system pressure exceeds a safe limit, venting refrigerant vapor or liquid to prevent components from being damaged or the vessel from rupturing. This automatic safety action helps avert catastrophic failures that can occur if heat input or a malfunction drives pressure beyond the design rating, keeping people and equipment safer. The automatic low-pressure switch protects the compressor from damage due to abnormally low suction pressure, but it doesn’t prevent high-pressure buildup. A surge tank is used in some fluid systems to dampen pressure surges, not as a standard safety device for typical refrigerant circuits. A backflow preventer protects potable water systems from contamination and isn’t part of refrigerant circuit protection.
