1 / 9

Why is it important to control the relative humidity in an air-conditioned space?

D) To decrease indoor air pressure

C) To improve comfort and prevent mold growth

B) To prevent excessive energy use

A) To minimize noise levels in the room

2 / 9

Which setting adjustment helps an air conditioning system reduce humidity while avoiding overcooling?

A) Increase the compressor's cycling rate

D) Turn off the system after reaching the desired temperature

B) Lower the setpoint for the cooling cycle

C) Use the "Dry Mode" setting, if available

3 / 9

What is one of the primary methods used to control relative humidity in an air conditioning system?

C) Increasing the system's air filter density

A) Adjusting the fan speed only

D) Adding extra refrigerant to the compressor

B) Using a humidifier or dehumidifier in conjunction with the system

4 / 9

What role does the reheat coil play in controlling humidity in an air conditioning system?

C) It filters the air to remove pollutants

B) It reheats the air after dehumidification to maintain temperature without adding moisture

A) It cools the air further to remove moisture

D) It increases humidity by adding moisture

5 / 9

What adjustment can be made to the air conditioning system to lower the indoor humidity level?

B) Lower the temperature setting on the thermostat

D) Decrease the airflow rate over the cooling coil

C) Use a higher efficiency air filter

A) Increase the speed of the evaporator fan

6 / 9

What advanced system can be used to automatically maintain the desired humidity level?

C) A high-speed fan controller

B) An integrated building management system (BMS) with humidity sensors

A) A basic thermostat

D) An extra condenser

7 / 9

How can the cooling coil in an air conditioning system contribute to humidity control?

C) By adding water vapor to the air

A) By raising the temperature in the room

D) By preventing air circulation

B) By condensing moisture from the air as it cools, thereby reducing humidity

8 / 9

What component in an air conditioning system is used to add moisture to the air when the relative humidity is too low?

C) Compressor

A) Condenser

D) Evaporator

B) Humidifier

9 / 9

What is the effect of an oversized air conditioning system on humidity control?

A) It maintains perfect humidity control by running continuously

B) It removes excessive moisture effectively

D) It increases the indoor humidity levels

C) It may fail to remove enough humidity because it cools the space too quickly
