Automotive HVAC Intro

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

• Condenser

• Receiver dryer

• Evaporator

• Compressor

Which component squeezes refrigerant vapor and moves it through the system?

• Compressor

• Condenser

• Evaporator

• Thermal eXpansion Valve

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

The air conditioning compressor acts as the ________ of the system, keeping refrigerant circulating during air conditioning system operation.

• Top
• Bottom
• Pump
• brain

The __________is placed ahead of the radiator, allowing it to receive maximum air flow from vehicle movement and coolant fan operation. 

• condenser
• compressor
• evaporator
• orifice tube

What does a Thermal eXpansion 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

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.

Where does the low pressure liquid become a gas?

• Evaporator

• Condenser

• TX valve

• Compressor

As refrigerant moves through the condenser it goes from _____ to ________

• a Vapor to a Liquid

• a Liquid to a Vapor

• Low pressure Vapor to a low pressure vapor

• High pressure liquid to a low pressure liquid
