Which ASHRAE standard pertains to refrigerant monitors that sound alarms and start ventilation systems?

• A. ASHRAE Standard 20
• B. ASHRAE Standard 15
• C. ASHRAE Standard 30
• D. ASHRAE Standard 50

Answer: (B)

ASHRAE Standard 15 is the correct reference for refrigerant monitoring systems that include alarms and initiate ventilation in case of a refrigerant leak. This standard outlines the safety requirements for refrigeration systems using refrigerants, with a focus on minimizing hazards related to exposure.

Standard 15 specifically addresses the detection of refrigerant leaks and the necessary responses, which can include sounding alarms and activating ventilation systems to prevent harmful exposure to refrigerants. This is crucial in maintaining safe working environments, particularly in enclosed spaces where refrigerants might accumulate.

The other standards mentioned do not focus directly on the specifics of refrigerant monitoring and alarm systems. They deal with different aspects of refrigeration technology and standards, such as testing methods, systems design, or energy efficiency, rather than the safety protocols related to refrigerant leaks.
