Question 1

30%

Answer 1

In 2019, EPA regulations require that leaking industrial process refrigeration with Ozone-depleting refrigeerant be repaired (or retrofitted or retired) when leak rate exceeds 30%

Question 2

15 psig

Answer 2

The typical design burst pressure for a rupture disk on a low pressure centrifugal ac systems.

Question 3

Pressure reliefe valves

Answer 3

Must NOT be installed in series

Question 4

Use of Gloves and sfety goggles

Answer 4

A safety precaution that should be adhered to for low pressure systems is the use of gloves and safety goggles when working with liquid refrigerant.

Question 5

High Head Pressure

Answer 5

Indicates air in a low pressure system.

Question 6

Compressor Replacement

Answer 6

Replacing a compressor always falls under the EPA definition for major maintenance service or repair.

Question 7

25 mm of Hg Absolute

Answer 7

Technicians must recover refrigerant to a level of 25 mm of Hg absolute before disposing a low pressure appliance.

Question 8

Extending Appliance Repair Deadlines

Answer 8

A certified service tech not being available CANNOT be used as a reason to extend the appliance repair deadlines.

Question 9

Within 10 days

Answer 9

a follow up leak verification test must be conducted within 10 days after a chiller with a charge of 200 pounds of refrigerant has passed the initial verification leak test.

Question 10

Comfort Cooling

Answer 10

The leak repair category defined by the EPA as AC appliances used to provide cooling in order to control heat and/or humidity. Chillers generally belong in the comfort cooling category.

Question 11

20%

Answer 11

In 2019 the EPA requires that commercial refrigeration systems containing 50 or more pounds of an HCFC be repaired when leak rates reach 20%.

Question 12

100 pounds

Answer 12

Approximately 100 pounds’ of refrigerant vapor is left in an average 350-ton R-123 chiller at 0psig once all the R123 liquid has been removed.

Question 13

Mothballing

Answer 13

In order to mothball an appliance using an ozone-depleting refrigerant, it is NOT required that you remove the appliance and store it in a warehouse at the facility.

Question 14

30 days

Answer 14

If a chiller containing 150 pounds of HCFC refrigerant is leaking beyond the applicable leak rate threshold, unless granted additional time , you have 30 days to repair the appliance so that if leaks below the threshold and conduct the initial leak verification test.
