How Air Conditioners Function: An In-Depth Look at Components and Processes

This video tutorial explains the working procedure of an air conditioner, detailing its major components: compressor, condenser, expansion valve, and evaporator. It describes the basic principle of air conditioning, which involves removing heat from an area and replacing it with cool air using a refrigerant called Freon. The video covers the functions of each component, including how the compressor pressurizes the refrigerant, the condenser expels heat, the expansion valve cools the refrigerant, and the evaporator absorbs heat to cool the indoor environment. The process is a continuous cycle that maintains a cool indoor atmosphere.

Which of the following is NOT a major component of an air conditioner?

• Condenser

• Evaporator

• Heater

• Compressor

What is the primary role of the refrigerant in an air conditioner?

• To heat the indoor air

• To facilitate heat exchange

• To provide electricity

• To filter the air

Why does the compressor increase the pressure of the refrigerant?

• To increase its temperature

• To change its color

• To make it lighter

• To cool it down

In the condenser, what change occurs to the refrigerant?

• It evaporates

• It becomes solid

• It turns from gas to liquid

• It turns from liquid to gas

What is the purpose of the expansion valve in an air conditioner?

• To cool and depressurize the refrigerant

• To increase the refrigerant's pressure

• To heat the refrigerant

• To filter the refrigerant

Which component is responsible for expelling heat to the outside environment?

• Evaporator

• Compressor

• Condenser

• Expansion valve

What is the role of the fan in the condenser unit?

• To cool the refrigerant

• To circulate refrigerant

• To heat the refrigerant

• To expel heat to the environment

Where does the refrigerant absorb heat from the indoor environment?

• In the compressor

• In the expansion valve

• In the evaporator

• In the condenser

What happens to the refrigerant after it absorbs heat in the evaporator?

• It remains unchanged

• It becomes a liquid

• It evaporates into a vapor

• It turns into a solid

How does the air conditioner maintain a continuous cooling cycle?

• By stopping and starting frequently

• By changing the refrigerant type

• By continuously cycling the refrigerant

• By using multiple compressors
