Air Conditioning

Which engine driven device compresses refrigerant and pumps it through the air conditioning system?

• condenser

• A/C lines

• receiver/Dryer

• compressor

- a chemical compound used in an A/C system to remove heat from the evaporator and transfer it to the condenser.

• refrigerant

• coolant

• hydraulic oil

• anti-freeze

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 TXV
• Between the TXV and the Evaporator
• Between the compressor and the condenser
• Between the Condenser and the TXV

What does a TXV 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 air conditioning compressor _____________ vaporized refrigerant and allows it to flow to the condenser. 

• pressurizes
• cools
• supplies
• cleans

Air Conditioning........

• the process for treating air

• to control its temperature

• to control its humidity

• to control its cleanliness

What are the four major components of an air conditioning system?

• Condenser

• Conduction

• Compressor

• Evaporator

• Thermal expansion valves

What happened in compressor?

• First the refrigerant is compressed; turn it into high pressure vapor. Then it is sent into the condenser.

• The axle fan will blow the condenser, where its function to cool the refrigerant in the refrigeration cycle.

• The high-pressure liquid is sent into the expansion valve; turns into low pressure liquid. Then it is sent into the evaporator.

• Finally the low-pressure vapor is back to the compressor for the same process; the overall process is repeated over and over again.

What type of air conditioning in the image?

• Window unit

• Split unit

• Centralised system

• Packaged unit
