Chapter 46, Problem 1RQ
A typical room air-conditioning unit has _____(one or two) fan motors.
Expert Solution & Answer
To determine
To Fill: The correct word for the given sentence.
Answer to Problem 1RQ
One double shaft fan motor is used inroom air-conditioning unit.
Explanation of Solution
The air-conditioning system absorbs the heat that leaks into the structure and deposit it outside the structure. The room air conditioners remove the excess heat and moisture from the interior of the room and sent it to the surroundings. The parts of air-conditioning unit are:
- Compressor
- Fan
- Condenser coils
- Evaporator coils
- Refrigerant.
The room air-conditioning unit is classified either window or split type. In both these types, the air-conditioning system has only one double−shaft fan motor for the evaporator and condenser. Thus, there will be only fan in air-conditioning unit.
