Refrigeration Cycle Basics
This is the process of removing heat from a space.
What is refrigeration?
This component removes heat and condenses refrigerant into a liquid.
What is the condenser?
This law regulates refrigerants and ozone-depleting substances.
What is the Clean Air Act?
This refrigerant replaced R-22 in many residential systems.
What is R-410A?
You must always wear this when working with refrigerants.
What are safety glasses (PPE)?
Heat is absorbed in this component.
What is the evaporator?
This device controls the flow of refrigerant into the evaporator.
What is a metering device (TXV/orifice)?
Venting refrigerant to the atmosphere is __________.
What is illegal?
This refrigerant is known for damaging the ozone layer.
What is CFC?
This gas can displace oxygen and cause suffocation in confined spaces.
What is refrigerant vapor?
This is where refrigerant changes from a low-pressure vapor to a high-pressure vapor.
What is the compressor?
This line carries low-pressure vapor back to the compressor.
What is the suction line?
This certification is required to handle refrigerants.
What is EPA 608 Certification?
This type of oil is used with HFC refrigerants like R-410A.
What is POE oil?
This must be used when removing refrigerant from a system.
What is a recovery machine?
This type of heat is added to change a liquid into a vapor without changing temperature.
What is latent heat?
This component increases both pressure and temperature of refrigerant.
What is the compressor?
This type of certification allows you to work on all systems.
What is Universal Certification?
What common refrigerant is in the process of being phased out as of 2025?
What is R-410A?
This type of cylinder is used to store recovered refrigerant.
What is a recovery cylinder?
This is the unwanted vapor formed before the metering device due to pressure drop.
What is flash gas?
This device prevents liquid refrigerant from entering the compressor.
What is an accumulator?
Appliances containing less than 5 lbs of refrigerant fall under this category.
What are Small Appliances (Type I)?
This term describes a refrigerant’s ability to harm the ozone layer.
What is ODP (Ozone Depletion Potential)?
Heating a sealed refrigerant cylinder can cause this dangerous event.
What is an explosion?
