What is the first step in the refrigeration cycle?
Metering Device
Evaporator
Condenser
Compressor
What does the 1st Law of Thermodynamics state?
Energy is always lost in a system
Energy travels from low to high levels
Energy cannot be created or destroyed
Energy can be created and destroyed
What is the purpose of the condenser in the refrigeration cycle?
To reduce refrigerant pressure
To convert vapor refrigerant into liquid refrigerant
To absorb heat from the surroundings
To create a pressure difference
What is latent heat?
Heat that changes the temperature of a substance
Heat that is always lost in a system
Heat absorbed or released during a change of state
Heat that can be measured directly
What happens during the superheating process?
The liquid refrigerant is converted to vapor
The vapor is cooled below its boiling point
The vapor temperature is raised above its boiling point
The refrigerant is condensed into a liquid
What is the function of the metering device?
To absorb heat from the surroundings
To reduce the refrigerant pressure
To create a flow of refrigerant
To convert vapor refrigerant into liquid refrigerant
What is the main function of the evaporator?
To cool the refrigerant
To absorb heat from the outer surroundings
To compress the refrigerant
To convert liquid refrigerant into vapor
What does the 2nd Law of Thermodynamics state?
Heat can flow from cold to hot
Energy cannot be created or destroyed
Energy is always conserved
Heat travels from hot to cold
What is sensible heat?
Heat that is absorbed during vaporization
Heat that is released during fusion
Heat that changes the state of a substance
Heat that can be measured by temperature change
What occurs in the compressor stage?
The refrigerant changes from liquid to vapor
The refrigerant pressure is reduced
The refrigerant is cooled
The refrigerant is heated and pressurized
What is the result of the expansion device's function?
Decrease in refrigerant pressure
Increase in refrigerant temperature
Increase in refrigerant pressure
Decrease in refrigerant temperature
What happens to the refrigerant in the evaporator?
It absorbs heat and turns into a gas
It releases heat and turns into a liquid
It is compressed into a high-pressure vapor
It remains at a constant temperature
What is the primary role of the compressor?
To convert liquid refrigerant into vapor
To cool the refrigerant
To create a flow of refrigerant
To absorb heat from the air
What is the process of evaporation in the evaporator?
Liquid refrigerant turns into vapor
Heat is released to the surroundings
Vapor refrigerant turns into liquid
Heat is absorbed from the refrigerant
