What is the Montreal Protocol?
¿Qué es el Protocolo de Montreal?
The definition of a small appliance includes; product manufactured, fully charged, and hermetically sealed in a factory containing what amount or less of refrigerant.
What is five pounds or less? (Pg. 16 para 2)
To reduce recovery time, you can do this to the recovery cylinder to reduce recovery time.
What is cooling the recovery cylinder? (Pg. 22 para 1)
Type 3 certification will allow a technician to work with these type of appliances.
What is low-pressure appliances? (Pg. 24 para 1)
These 4 major components of a refrigeration cycle include what?
What is the compressor, the metering device, the evaporator and the condenser? (Pg.3)
This process means to extract refrigerants from and appliance and clean the refrigeration for reuse in equipment of the same owner.
Este proceso significa extraer refrigerantes de un aparato y limpiar la refrigeración para reutilizarla en equipos del mismo propietario.
What is Recycling?
¿Qué es el reciclaje?
This is where you would put the hoses connected to the gauge manifold when recovering refrigerant from a household refrigerator or any other appliance to improve the speed of recovery.
What is the low and high-side access valves. (Pg. 17 para 10)
This is the recovery level of evacuation during recovery you must achieve for a very-high pressure appliance.
0” Hg (pg. 22)
When leak testing a low-pressure centrifugal chiller with nitrogen, this is the maximum test pressure in PSIG.
What is 10 PSIG. (Pg. 24 para 4)
In a refrigeration system this device/component rejects heat to the outside from the refrigerant.
What is the condenser?
What is an electric or ultrasonic leak detector?
Non-condensable gas in the refrigerant can be checked for by using this kind of chart.
What is a pressure-temperature (PT) chart? (Pg.18 para 2)
This is the recovery level of evacuation during recovery you must achieve for a medium-pressure appliance with less than 200lbs of refrigerant.
10” Hg (pg. 22)
The system should be checked for leaks if, during a standard vacuum test, the pressure in a system rises from _____mm Hg to a level above _____mm Hg.
What is 1mm Hg to a level above 2.5mm Hg? (Pg.24 para 7)
This device/component allows for heat to be rejected in the high pressure line and allow for heat to be absorbed in the low pressure line.
In the event of a large release of CFC, HCFC, HFC, HFO, HC, or any other refrigerant in a contained area, you must follow one of these two steps.
What is using a self-contained breathing apparatus (SCBA) or leaving the area?
When filling a charging cylinder with a regulated refrigerant, you must _____ the refrigerant that is vented off the top.
Recover (pg. 16 para 10)
This equipment/part is required to be on gauge hoses that are connected to the recovery unit to the tank to minimize refrigerant release when the hoses are connected or disconnected.
What is Self-sealing connectors or hand valves? (Pg.21 para.8)
Before disposing of a low-pressure appliance, the refrigerant must be recovered or evacuated to a level of X mm of Hg absolute.
What is 25 mm of Hg absolute? (Pg. 26 para 6)
This happens when vapor has heat added above its vaporization point.
What is superheat?
This refrigerants can be slightly flammable and have no ozone depletion potential but do have a very small effect on global warming.
What is an HFO?
This accessory is typically used on small appliances and is a straight piece of tubing that is entered using a piercing access valve to add or remove refrigerant from a small appliance.
What is the service aperture or process stub? (Pg. 17 para 7)
This accessory, that is used for checking refrigerant moisture, is located in the liquid line, immediately downstream, after the liquid-line filter drier.
What is a sight glass? (Pg. 23 para 1)
To convert from an absolute pressure (psia) to gauge pressure (psig) subtract this amount from the absolute pressure.
What is 14.7? (Pg.26 para 9)
If a chiller with a charge of 200lbs of an ozone-depleting refrigerant has passed the initial verification leak test, a follow-up verification test must be conducted within this many days.
What is 10 days? (Pg. 25 para 9)
