Refrigeration Cycle
The "heart" of the refrigeration system
What is the compressor?
This compressor component is used to help prevent refrigerant migration.
What is the crankcase heater?
This protects the earth from UV radiation from the sun.
What is the ozone layer?
This gas is used as the baseline measurement for global warming potential and has a value of 1.
What is carbon dioxide (CO2)?
This act sets forth the rules and regulations for refrigerant handling in the HVACR industry.
What is the Clean Air Act?
This is where heat is removed
What is the condenser?
This procedure should be performed whenever a refrigeration circuit has had a leak or major component failure, such as a compressor burn-out.
What is an oil sample?
This term is used to measure the ability of a substance to destroy ozone in the stratosphere.
What is Ozone depletion potential (or ODP)?
Most HFC refrigerants, such as this refrigerant, have global warming potentials thousands of times greater compared to carbon dioxide
What is R-410A?
A person is not required to be a Section 608 certified technician when servicing this part of the refrigeration system.
What is an external electric circuit?
This is where refrigerant enters as a high-pressure, subcooled liquid and leaves as a low-pressure/low-temperature liquid.
What is the metering device?
This is the minimum level an appliance should be dehydrated by evacuation (vacuum) after finding and repairing leaks.
What is 500 microns?
Ozone in the stratosphere consists of molecules containing this amount.
What are 3 oxygen atoms?
This class of refrigerants have the lowest global warming potential compared to CFCs, HCFCs, and HFCs.
What are Hydrocarbons (HC) and Hydrofluoroolefin (HFO) refrigerants?
As of 2017, a technician can be fined this amount per day, per violation, for violating the Clean Air Act, including knowingly releasing non-exempt refrigerant from appliances.
What is $44,539?
This is where refrigerant enters as a low-temperature/low-pressure liquid and leaves as a low-temperature/low-pressure superheated-vapor.
What is the evaporator?
This illegal procedure involves flushing field tubing to clean it after a compressor burn-out.
What is flushing with liquid refrigerant?
A single chlorine atom can last in the Stratosphere for 120 years destroying up to this many molecules.
What is 100,000 ozone molecules?
This class of refrigerants have the highest ozone depletion potential (ODP) and are the most harmful to stratospheric ozone.
What are Chlorofluorocarbon (CFC) refrigerants?
This procedure must be performed when discarding any disposable cylinders of CFCs, HCFCs, HFCs, or HFOs.
What is recovery?
This service valve position closes the service port to allow removal of the manifold hoses.
What is the back-seated position?
Under no circumstance should a hermetic compressor be operated in this state.
What is a vacuum?
This substance found in CFCs and HCFCs will neither dissolve in water nor break down into compounds that dissolve in water so they do not rain out of the atmosphere.
What is chlorine?
Although flammable, these refrigerants pose the least amount of danger to the environment.
What are Hydrocarbon (HC) refrigerants?
Reclaimed refrigerant must meet this AHRI Standard before it can be resold under EPA’s regulations.
What is AHRI Standard 700?
