What are the differences between passive and active cooling systems?

What are the differences between passive and active cooling systems?

Passive cooling systems rely on natural processes like ventilation and thermal mass, while active cooling systems use mechanical means like fans or chillers.

Can you give examples of each type?

Sure! An example of passive cooling is using shaded windows and thermal mass in buildings. An active cooling example is an air conditioning unit.

Which one is more energy-efficient?

Generally, passive cooling is more energy-efficient as it uses natural methods, while active cooling consumes more energy due to mechanical components.

Are there situations where active cooling is necessary?

Yes, in extreme heat conditions or in spaces with high heat loads, active cooling may be necessary to maintain comfortable temperatures.

What are the costs associated with each system?

Passive cooling systems often have lower initial costs but may require more design consideration. Active cooling systems have higher upfront and operational costs.
