Machinery rooms are mandated when the quantities of refrigerants exceed specific thresholds established by the code. These thresholds are in place to ensure safety and effective management of refrigerant-related risks, such as leaks or spills that could pose health or environmental hazards. When the refrigerant quantity surpasses these set limits, dedicated machinery rooms are required to confine and contain the refrigerants safely, allowing for proper ventilation and maintenance.

This requirement serves multiple purposes, including controlling potential exposure to harmful refrigerants, providing sufficient access for maintenance, and ensuring compliance with standards that prevent accidental discharge into occupied areas. By establishing machinery rooms under these circumstances, the code adds a structured approach to addressing the potential hazards associated with higher refrigerant quantities.
