What is used to keep the internal rack temperature below the ambient room temperature?

A. Forced-air ventilator
B. Water-cooled heat exchanger
C. Air-cooled heat exchanger
D. Air conditioner

Answer :

Final answer:

The best option to keep internal rack temperatures below ambient room temperature is an air conditioner, which effectively cools indoor air by transferring heat outdoors. Other options like heat exchangers have specific applications but are not as universally applicable. A forced-air ventilator primarily circulates air without cooling it.


Explanation:

Understanding Cooling Systems

To keep the internal rack temperature below the ambient room temperature, several cooling systems can be employed. The correct option among the provided choices is:

  1. d. Air conditioner

An air conditioner functions by transferring heat from the indoor environment to the outdoors, thereby lowering the internal temperature. It utilizes the principle of thermodynamics, particularly the refrigeration cycle, to absorb heat from the air inside a space and release it outside, ensuring a cooler indoor atmosphere.

While a water-cooled heat exchanger and an air-cooled heat exchanger can also regulate temperatures, they are typically used in specific applications and not as universally as air conditioners in maintaining a constant lower temperature indoors. A forced-air ventilator mainly circulates air and does not actively cool the air, making it less effective for this purpose.
