Where must the discharge from a rupture disc on a low pressure chiller be piped for venting?

The discharge from a rupture disc on a low-pressure chiller must be piped outdoors for venting to ensure safety and compliance with industry standards. This is crucial because the purpose of a rupture disc is to provide a safe release of pressure in the event of overpressure conditions. If venting were to occur indoors, it could pose significant hazards, including the risk of exposure to potentially harmful refrigerants or other gases, leading to safety issues for personnel and structural damage to the facility.

By directing the discharge outside, the risk of accumulation of any released substances is mitigated, protecting the environment and ensuring that the area remains safe for operations. Outdoor venting also aligns with regulatory requirements, which often mandate that any exhaust from pressure release devices is safely directed away from occupied spaces.

Options that suggest discharging indoors, into a containment unit, or through a filter do not provide the necessary safety guarantees or comply with standard practices for managing pressure releases in chillers.
