1 / 9

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

D) Decrease the airflow rate over the cooling coil

A) Increase the speed of the evaporator fan

B) Lower the temperature setting on the thermostat

C) Use a higher efficiency air filter

2 / 9

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

B) Lower the setpoint for the cooling cycle

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

A) Increase the compressor's cycling rate

D) Turn off the system after reaching the desired temperature

3 / 9

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

B) Humidifier

A) Condenser

D) Evaporator

C) Compressor

4 / 9

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

A) A basic thermostat

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

C) A high-speed fan controller

D) An extra condenser

5 / 9

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

B) It removes excessive moisture effectively

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

A) It maintains perfect humidity control by running continuously

D) It increases the indoor humidity levels

6 / 9

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

C) To improve comfort and prevent mold growth

B) To prevent excessive energy use

D) To decrease indoor air pressure

A) To minimize noise levels in the room

7 / 9

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

A) It cools the air further to remove moisture

D) It increases humidity by adding moisture

C) It filters the air to remove pollutants

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

8 / 9

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

A) Adjusting the fan speed only

C) Increasing the system's air filter density

D) Adding extra refrigerant to the compressor

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

9 / 9

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

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

C) By adding water vapor to the air
