Understanding Car Air Conditioning Systems

What is the primary function of a car's air conditioning system?

• To filter out pollutants

• To heat the car interior

• To cool and remove humidity from the air

• To increase engine efficiency

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

• Compressor

• Evaporator

• Condenser

• Receiver-Dryer

What happens to the refrigerant in the condenser?

• It is cooled and condensed into a liquid

• It is heated and evaporated into a gas

• It is expanded into a liquid

• It is compressed into a gas

What is the role of the receiver-dryer in the air conditioning system?

• To heat the refrigerant

• To cool the refrigerant

• To remove moisture from the refrigerant

• To compress the refrigerant

Where is the evaporator typically located in a car?

• In the engine compartment

• Above the footwell on the passenger side

• Under the driver's seat

• In the trunk

What is the purpose of the thermal expansion valve?

• To compress the refrigerant

• To heat the refrigerant

• To filter the refrigerant

• To regulate the flow of refrigerant

How often should a car's AC system be serviced for optimal performance?

• Every 6 months

• Every 1-2 years

• Every 5 years

• Only when it stops working

What is a common consequence of not removing moisture from the AC system?

• Increased cooling efficiency

• Formation of acids and sludge

• Improved air quality

• Reduced engine power

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

• High-pressure gas

• Low-pressure liquid

• High-pressure liquid

• Low-pressure gas

What should you do if your car's AC system is not functioning properly?

• Wait for it to fix itself

• Seek help from an experienced automotive air conditioning technician

• Ignore it

• Try to fix it yourself
