Question

What are the primary energy sources used to operate a building's air conditioning controller?

  • A. Electric
  • B. Pneumatic
  • C. Hydraulic
  • D. Passive
Answer

Electric, pneumatic and hydraulic are typically the common primary energy sources used to operate a building's air conditioning controller.

The energy sources mentioned come in different forms, but a building's air conditioning controller running on electricity would be the most common. Pneumatic actuators may also be utilized, which work by the use of compressed air, and hydraulic actuators may also be used for larger equipment. Passive energy sources that come from the surrounding environment can also provide cooling and heating, but they may need further modifications to be utilized by an air conditioning controller.
