Question

Which is not the core component of central A.C. ?

• A. Washer
• B. Compressor
• C. Evaporator
• D. Condenser

Hint:

The core parts are those of the refrigeration cycle. One option is only an air treatment unit.

Answer 1

The Correct Option is A

Step 1: Recall a central A.C. system:
A central air conditioning system cools many rooms from one plant. The plant is a refrigeration unit that cools air or chilled water. Ducts or pipes then carry the cooling to the rooms.

Step 2: Name the core components:
The core of the refrigeration unit is the compressor, condenser, expansion device and evaporator (the cooling coil or chiller).

Step 3: Check the options:
Compressor, evaporator and condenser are all core components, so (B), (C) and (D) are wrong choices.
Washer (an air washer that cleans and humidifies air with sprays) is an extra unit. It is not a core part of the refrigeration circuit, so (A) is the answer.

Final Answer:
Washer is not a core component of a central A.C. This is option (A).
