Question

Zero energy cool chambers work on the principle of ________ cooling.

• A. \(\text{Hydro}\)
• B. \(\text{Evaporative}\)
• C. \(\text{Vacuum}\)
• D. \(\text{Room}\)

Hint:

Evaporative cooling is an eco-friendly and cost-effective method for storing perishable goods.

Answer 1

The Correct Option is B

Step 1: Understanding zero energy cool chambers.
- These chambers use the principle of evaporative cooling, where water evaporation reduces temperature.
Step 2: Explanation of incorrect options.
- (A) Hydro: Involves liquid cooling, not evaporation.
- (C) Vacuum: Used in advanced cooling methods, not traditional chambers.
- (D) Room: Not a cooling mechanism.
Step 3: Selecting the correct option. Since zero energy cool chambers use evaporative cooling, the correct answer is (B) Evaporative.
