Hotel Service Unit 11 Q6 Quiz

Correct Answer:
A) Evaporator

Explanation:
The evaporator is a key component where the refrigerant absorbs heat from the surrounding area, cooling the environment by evaporation.

Correct Answer:
C) Low-pressure liquid

Explanation:
The refrigerant enters the evaporator as a low-pressure liquid, where it absorbs heat and evaporates, cooling the surrounding area.

Correct Answer:
A) Compressor

Explanation:
The refrigerant reaches its highest pressure and temperature immediately after leaving the compressor, making it ready to release heat in the condenser.

Correct Answer:
C) Expansion Valve

Explanation:
The expansion valve controls the flow of refrigerant, allowing it to expand and drop in pressure as it enters the evaporator, where it absorbs heat.

Correct Answer:
B) To increase the refrigerant pressure and temperature, moving it to the condenser

Explanation:
The compressor increases the refrigerant’s pressure and temperature, which allows it to release absorbed heat in the condenser.

Correct Answer:
C) Pressure and temperature both decrease as the refrigerant expands

Explanation:
In the expansion valve, the refrigerant’s pressure and temperature drop as it expands, preparing it to absorb heat in the evaporator.

Correct Answer:
A) High-pressure liquid

Explanation:
After releasing heat in the condenser, the refrigerant becomes a high-pressure liquid, which flows to the expansion valve for the next cycle stage.

Correct Answer:
B) Low-pressure vapor

Explanation:
As the refrigerant enters the compressor, it is in a low-pressure vapor state. The compressor then raises its pressure and temperature to prepare it for condensation.

Correct Answer:
B) It removes heat from the refrigerant, condensing it back into a liquid

Explanation:
The condenser releases the heat absorbed by the refrigerant, cooling it and returning it to a liquid state for reuse in the cycle.
