Exam Questions and Answers | 100%
Solved
What are the comfort-related properties of indoor air that climate sensors
measure?I. CirculationII. FiltrationIII. HumidityIV. TemperatureV. Ventilation
- 🧠ANSWER ✔✔I., II., III., IV., and V
What types of temperature-sensing elements output an electrical signal? -
🧠ANSWER ✔✔Resistance temperature detectors (RTD)
Thermistors
Thermocouples
When the ? and the sensor electronics are connected with long conductors,
the long conductors add resistance to a circuit, which affects the voltage
measurement and makes the device susceptible to inaccuracies. -

, What do most hygrometers measure? - 🧠ANSWER ✔✔% relative humidity
? is used to compare the air pressure between two points within a duct,
which is used to monitor fan operation or filter condition. - 🧠ANSWER
✔✔Differential pressure
Differential pressure switches are often used across a ? and indicate
conditions that are impeding airflow. - 🧠ANSWER ✔✔Fan or filter
What type of sensor measures the velocity of the air in a duct system? -
🧠ANSWER ✔✔An airflow station
What primary methods are used to improve indoor air quality? - 🧠ANSWER
✔✔Filtration
Source control
Ventilation
Which of the following devices are not commonly used to control
temperature within a building or building zone? - 🧠ANSWER ✔✔Humidifiers
