What should the size of a ventilation system for refrigerant removal be based on?

The size of a ventilation system for refrigerant removal should primarily be based on the amount of refrigerant being used and the capacity of the largest machine in the environment. This ensures that the system can effectively handle the maximum potential refrigerant release in case of a leak or system failure. Proper sizing accounts for both the quantity of refrigerant and the specific requirements of the equipment in use, which is critical for safety and compliance with regulations regarding air quality and toxic exposure.

Inadequately sizing the ventilation system could result in insufficient air exchange, leading to hazardous conditions if a refrigerant leak occurs. By ensuring the ventilation system is appropriately sized according to the largest machine and the expected refrigerant quantities, one can mitigate risks associated with refrigerant exposure and maintain safe operating conditions.
