Understanding Automotive AC Systems

Which component of an automotive AC system is responsible for compressing the refrigerant?

• Evaporator

• Compressor

• Condenser

• Expansion valve

What is the primary function of the condenser in an automotive AC system?

• To absorb heat from the cabin

• To compress the refrigerant

• To release heat to the outside air

• To regulate refrigerant flow

In an automotive AC system, which component is responsible for absorbing heat from the vehicle's interior?

• Condenser

• Compressor

• Evaporator

• Receiver-drier

Which principle explains the cooling effect in an automotive AC system?

• Boyle's Law

• Charles's Law

• Heat exchange through phase change

• Newton's Law of Cooling

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

• To increase refrigerant pressure

• To decrease refrigerant pressure

• To absorb heat from the cabin

• To release heat to the outside air

Which of the following equations represents the relationship between pressure, volume, and temperature in a gas, relevant to AC systems?

What is the primary purpose of the receiver-drier in an automotive AC system?

• To compress the refrigerant

• To absorb moisture and filter debris

• To release heat to the outside air

• To regulate refrigerant flow

Which component of the AC system is typically located in front of the radiator?

• Evaporator

• Compressor

• Condenser

• Expansion valve

What happens to the refrigerant as it passes through the evaporator?

• It condenses and releases heat

• It evaporates and absorbs heat

• It compresses and increases in temperature

• It expands and decreases in pressure

Which of the following best describes the heat exchange process in an automotive AC system?

• Heat is absorbed from the outside air and released inside the vehicle

• Heat is absorbed from the vehicle's interior and released outside

• Heat is generated by the compressor and absorbed by the condenser

• Heat is absorbed by the expansion valve and released by the evaporator
