What is the purpose of the compressor in a vehicle air conditioning system?

• To cool down the refrigerant
• To circulate the refrigerant
• To remove moisture from the air
• To pressurize the refrigerant

What type of refrigerant is commonly used in modern vehicle air conditioning systems?

• R-12
• R-134a
• R-22
• R-410a

What component of the system is responsible for removing heat from the refrigerant?

• Condenser
• Evaporator
• Expansion valve
• Receiver-dryer

What is the purpose of the receiver-dryer in a vehicle air conditioning system?

• To store excess refrigerant
• To remove moisture and contaminants from the refrigerant
• To regulate the flow of refrigerant
• To cool down the refrigerant

Which part of the air conditioning system is responsible for regulating the flow of refrigerant into the evaporator?

• Compressor
• Condenser
• Expansion valve
• Accumulator

What is the function of the evaporator in a vehicle air conditioning system?

• To pressurize the refrigerant
• To remove heat from the cabin air
• To cool down the refrigerant
• To remove moisture from the air

What causes the refrigerant to change from a gas to a liquid in the air conditioning system?

• Evaporation
• Condensation
• Compression
• Expansion

What part of the air conditioning system is responsible for storing excess refrigerant and preventing liquid refrigerant from entering the compressor?

• Evaporator
• Receiver-dryer
• Accumulator
• Condenser

What can cause a vehicle air conditioning system to blow warm air instead of cold air?

• Low refrigerant levels
• Clogged evaporator
• Faulty compressor
• Blocked condenser

What should be done if a vehicle air conditioning system is not cooling effectively?

• Add refrigerant
• Replace the compressor
• Clean the condenser
• Check for leaks
