EPA Core
ODP?
What is Ozone Depletion Potential
These appliances typically have less than 5 pounds of refrigerant charge and are hermetically sealed at the factory.
What are small appliances?
This component is used to trap solid contaminates and remove moisture from a system.
What is a filter-drier?
Pressure relief valves are typically set for this pressure and are vented to the outdoors.
What is 15 psig?
A full 50 pound cylinder will have this much refrigerant in it.
What is 40 pounds or 80%
This refrigerant, a near azeotropic 50/50 blend of HFC-32 and HFC-125 replaced HCFC-22
What is HFC-410A
This test consists of allowing a refrigerant to stabilize for at least 12 hours then compare pressure and temperature to a chart.
What is testing for non-condensibles?
Oil on the outside of tubing is an indication of this condition.
What is a refrigerant leak?
low pressure equipment operates below atmospheric pressure. to eliminate any air in the system due to leaks this device is used.
What is a purge unit?
The Color of a Recovery Tank is?
What is a Gray Body with a Yellow Top
These refrigerant blends act as a single compound refrigerant and do not fractionate.
What are Azeotropes
This is another term for a recovery device that does not have its own compressor, uses a non-pressurized container and is dependent on system pressure for recovery
What is passive recovery
On equipment with more than 50 pounds of charge, this person is responsible of reporting to EPA any efforts of identifying leaks, leak inspection/repair reports and keep these records for 3 years.
What is Owner/operators?
On systems with a charge over 500 regular inspections should be conducted. on systems found to be leaking this inspection rete is..
What is every 3 months (quarter) until the allowable leak rate threshold is not exceeded for 4 quarters?
Violation of the Clean Air Act penalties can be per day and per offense with possible loss of certification. This dollar amount is.
What is $44,539 ?
These refrigerant blends consist of 3 different refrigerant compounds and may or may not fractionate.
What are ternary blends
Refrigerant being heavier than air displaces oxygen and can lead to this condition especially in enclosed spaces.
What is suffocation or asphyxiation?
This recovery method is only usable if the appliance has less than 15 pounds of charge.
What is Passive or System dependent?
Recovery units high pressure cut out must be set for this pressure when being used for type 3 recovery.
What is 10 psig?
This new class of refrigerant is added for refrigerants that have low flammability.
What is A2L
These four main components that make up the basic refrigeration cycle
What are the Compressor, Condenser, Metering device and Evaporator?
These recovery requirements are for both passive and active systems and with a non-working compressor
What is 4 inches Hg or 80% ?
This method of refrigerant recovery is the fastest but has a drawback of potential loss of refrigerant oil.
What is liquid recovery?
These two exceptions to evacuation requirements on type 3 equipment exist.
What is a non-major repair or a leaking system?
Because of serious environmental damage that the release of refrigerant can cause only these individuals may purchase or handle refrigerants.
What is Certified Technicians?
