Automotive Air Conditioning Principals

In a typical system, within which component would the evaporation of refrigerant take place?

• Condenser
• Receiver dryer
• Evaporator
• Compressor

Where would you expect to find a high pressure liquid within an AC system?

• Between the compressor and the Thermal Xpansion Valve

• Between the Thermal Xpansion Valve and the Evaporator

• Between the compressor and the condenser

• Between the Condenser and the Thermal Xpansion Valve

What does a Thermal Xpansion Valve do?

• Cleans, dries and filters the refrigerant

• It controls the quantity of refrigerant entering the evaporator

• Allows for an increase in pressure and temperature prior to entering the condenser

• It acts as a safety device if the compressor is over pressuring the system

If contamination within an air conditioning system is suspected and a flushing procedure is to be carried out what component should also be changed?

• Compressor

• Receiver Drier

• Thermal Xpansion Valve

• Condenser

When leaving the compressor what state is the refrigerant in?

• High Pressure, High Temperature gas

• High Pressure, High Temperature liquid

• Low Pressure, low Temperature gas

• Low Pressure, low Temperature gas

The main components of the Air conditioning system are

• Thermistor, condenser, flow control and an evaporator.

• Fan blower, condenser, flow control and an evaporator.

• Compressor, condenser, TXV and an evaporator.

• Drainage, condenser, flow control and an evaporator.

Which component squeezes the gas?

• Compressor

• Condenser

• Evaporator

• Thermal Xpansion Valve

Which system has moving parts?

• Thermal Xpansion Valve

• Fixed orifice

• Variable Fixed Oriface

Where does the low pressure liquid become a gas?

• Evaporator

• Condenser

• TX valve

• Compressor

In what state is the refrigerant when it exits the condenser?

• High pressure gas

• Low pressure gas

• High pressure liquid

• Low pressure liquid
