| Question | Answer |
|---|---|
| Who keeps the records of leak inspections and for how long? | The owner or operator of the equipment is responsible of keeping the records and should be kept on file for 3 years. |
| what is considered an (IPR) Industrial process refrigeration? | If a company uses 55% of its systems cooling capacity to one of its manufacturing lines or refrigeration and 45% of its cooling capacity to air condition the office spaces. |
| How many pounds of refrigerant exceeds the threshold leak? | If an appliance with 50 or more pounds of a regulated refrigerant has exceeded the threshold leak rate,the owner has 30 days to repair the appliance. |
| Do an ozone-depleting refrigerant need to be removed or mothballed? | No, an appliance using an ozone-depleting refrigerant does not need to be removed or mothballed by storing in a warehouse at the facility. |
| Do you use a trace amount of the refrigerant for leak detection? | Yes, when necessary dry nitrogen with a trace of the system's design refrigerant should be used for leak detection. |
| Can a system greater than 15 pounds total charge be used? | No, EPA regulations prohibit use when appliance contains over 15 pounds of refrigerant. |
| How many months do the owner or operator or have to retire a leaking appliance? | The owner has 18 months to retire a leaking appliance if the replacement appliance will use a refrigerant exempt from the venting prohibition. |
| What should you look for while inspecting hermetic systems? | You should look for traces of oil when first inspecting an hermetic system. |
| What will happen if you cool the recovery cylinder? | It speeds the recovery process or removal of refrigerant charge from a system. |
| Where is the refrigerant receiver located? | It is typically located in the liquid line. |
| What is used to determine if a tube is leaking? | A hydrostatic tube test kit. |
| Because a low-pressure system operates below atmospheric pressure (in a vacuum), leaks in the gaskets or fittings will cause what to enter the system? | Air and moisture. |
| What is the maximum test pressure when leak testing a low-pressure centrifugal chiller with nitrogen? | 10 psig. |
| Why do low-pressure chillers require purge units? | Because they operate below atmospheric pressure. |
| What does high head pressure indicate? | It indicates air in a low-pressure system and that the purge unit may not be operating properly. |
| What could happen if a leak test was done on a low-pressure refrigeration chiller with nitrogen in excess of 10psig? | It could cause the rupture disc to fall. |
| How does moisture most frequently enter the refrigerant system in low-pressure chillers? | Through leaks from areas with gaskets or fittings. |
| If a chiller with a charge of 200 lb of an ozone depleting refrigerant has passed the initial verification leak test a follow up test must be conducted within how many days? | 10 days |
| The use of a severely oversized vacuum pump could cause what to happen? | Trapped water to freeze when evacuating/dehydrating a system. |
| When removing refrigerant oil what should it be heated to? | 130 degrees F |
