Air cooler working model for school science exhibition project

INTRODUCTION

In this topic, we are going to show you how to build a mini Air cooler working model using the waste plastic bottle at home for your science project or exhibitions.

This homemade mini air cooler is made up of the waste plastic bottle available at home at low cost.

How this air cooler works?

Mini air cooler works with 9 v battery, ice cube and plastic bottles and is economic and environmental-friendly too. It blows the air from the top towards the ice cubes then the cooled air exits from the outlet of the bottle.

Advantages of air cooler

  • affordable
  • lower cost
  • it uses water for cooling and do not refrigerate
  • ecofriendly
  • Fresh air with added moisture

Types of Air coolers

Questions & Answers

1. What is the basic working principle of air cooler?

Basic working principle of air cooler by water evaporation to cool the air, with this it absorbs the heat energy and lowers the air temperature.

2. How can I make my desert cooler more effective?

To make desert cooler more effective make sure of proper ventilation, add ice to water, good care of cooler and finally saturate the cooling pads before use.

3. Does air cooler good for health?

Yes, as there is natural evaporation of water, it is considered Eco-friendly and Green.

4. Does air cooler work in humid condition?

Yes, Works in humid conditions however its efficiency gets affected as evaporation becomes slow during high humidity.

Conclusions

Air cooler working model helps the students to learn about how the mini air cooler works and as well as how to make it with easily available materials at home.
