Comfort Cooling
Air-conditioning appliances used to supply cooling in order to control heat and/or humidity in occupied facilities
Commercial Refrigeration
Appliances (equipment) used to preserve products, as in the retail food and cold storage warehouse sectors
How do you determine system charge?
Use the charge stated on the equipment nameplate to determine normal charge for leak rate calculations when the system is a packaged system at the factory
Maximum leak rate for comfort cooling systems
10%
Maximum leak rate for commercial refrigeration
20%
Maximum leak rate for industrial process refrigeration
30%
How many days does the owner operator have to repair an appliance containing 50 or more pounds of regulated refrigerant that has exceeded the threshold leak rate?
30 days to repair so that it leaks below the limit and conduct initial verification test
If an appliance with at charge of 200 pounds or more of a regulated refrigerant passes the initial verification leak test, a follow-up test mused be conducted in how many days?
10 days
How long can a leaking appliance with regulated refrigerant run without repair before it must be retrofitted or retired?
12 months
If that system leak rate exceeds ______ % of its full charge in a calendar year, then a report must be submitted to EPA describing the efforts to identify and repair system leaks.
125%
Frequency of Leak Inspection for Comfort Cooling systems 50 pounds or more
Once per calendar year until owner/operator can demonstrate leak has not exceeded 10% for one year
Frequency of Leak Inspection for Commercial and Industrial Process 50 to 500 pounds
Once per calendar year until owner/operator can demonstrate leak has not exceeded 20% for commercial or 30% (IPR) for one year
Frequency of Leak Inspection for Commercial and Industrial Process more than 500 pounds
Once every three months until owner/operator demonstrates leak has not exceeded 20% commercial or 30% (IPR) for four quarters in a row
How long must records remain on file by owner/operator?
3 years. Leak inspections, initial leak verifcation and follow-up verification tests
Can system-dependent recovery methods be used on systems greater than 15 pounds?
NO
