air conditioner Quiz Practice Quiz | Air Conditioning

Q: What is the primary function of an air conditioner?

To cool and dehumidify air — Air conditioners primarily cool and remove moisture from the air.

Q: Which component is responsible for compressing the refrigerant in an AC system?

Compressor — The compressor increases the refrigerant's pressure, enabling heat transfer.

Q: Where does the cooling process primarily occur in a typical air conditioner?

Evaporator — The evaporator absorbs heat from the air inside the room.

Q: What happens to the refrigerant in the condenser?

It releases heat to the surrounding air. — The condenser releases the heat absorbed by the refrigerant.

Q: Which of the following is NOT a common type of air conditioner?

Water-cooled AC — Water-cooled AC is a method, not a type. Window, split, and central AC are common types.

Q: What is the purpose of the expansion valve (or capillary tube)?

To reduce the refrigerant's pressure and temperature. — The expansion valve reduces the refrigerant's pressure, causing it to cool.

Q: What type of refrigerant is commonly used in modern air conditioners?

R-134a — R-134a is a commonly used refrigerant in modern AC systems.

Q: What unit is used to measure the cooling capacity of an air conditioner?

BTU/hour — BTU/hour measures the rate of heat removal, indicating cooling capacity.

Q: What is the function of the fins on the evaporator and condenser coils?

To improve heat transfer. — Fins increase the surface area for efficient heat transfer.

Q: What is the main purpose of the drainage tube in an air conditioner?

To remove condensed water. — The drain tube removes condensed water (humidity) from the evaporator.
