Understanding Car AC Systems

Which component of the car air conditioning system is responsible for compressing the refrigerant?

• Evaporator

• Compressor

• Condenser

• Expansion valve

What is the primary function of the condenser in a car's AC system?

• To absorb heat from the cabin

• To compress the refrigerant

• To release heat to the outside air

• To regulate refrigerant flow

Which of the following is a common type of refrigerant used in modern car air conditioning systems?

• R-12

• R-134a

• R-22

• R-410A

What is the state of the refrigerant as it enters the evaporator?

• High-pressure liquid

• Low-pressure liquid

• High-pressure gas

• Low-pressure gas

At what temperature does the refrigerant typically evaporate in the evaporator?

• -10°C

• 0°C

• 5°C

• 10°C

Which component of the AC system is responsible for converting the refrigerant from a high-pressure gas to a high-pressure liquid?

• Compressor

• Condenser

• Evaporator

• Expansion valve

What is the primary property of refrigerants that makes them suitable for use in air conditioning systems?

• High boiling point

• Low freezing point

• High heat absorption capacity

• Low density

Which of the following pressures is typical for the high-pressure side of a car's AC system?

• 10 psi

• 50 psi

• 150 psi

• 250 psi

What is the role of the expansion valve in the AC system?

• To increase refrigerant pressure

• To decrease refrigerant pressure

• To absorb heat from the cabin

• To release heat to the outside

Which of the following is a characteristic of R-134a refrigerant?

• Ozone-depleting

• Non-flammable
