This project is inclined to design a useful and fully

functional Cooling system.

It is based on the relation between boiling point and

vapour pressure of water.

Introduction

Lowering the Vapour Pressure of water lowers the

boiling point of water respectively.

Heat Energy is required to boil the water.

Heat absorbed from a space makes temperature drop

in that space

Principle

Block Diagram of Vacuum Pressure Power Cooling

System

Vacuum Pump creates Vacuum Pressure of about 0.01

bar inside the water container.

Water starts boiling at room temperature.

Heat from Surrounding is consumed by water for

boiling.

As heat is absorbed the surrounding temperature drops.

Working

Ideal for short-term storage of Fruit Vegetable Medicines Vaccines Beverage bottles, etc Can be used in Cold storage ware houses.

Applications

Consumes significantly less electricity. No hazardous gases are released. Zero Pollution Can be made human powered by pedaling the pump. Completely Eco- friendly

Advantages

Large setup area required for large space cooling.

Water to be filled on regular basis.

Limitations

It could have been made human powered

by using a bicycle and running the pump by pedaling.

Could work with solar energy driven motor, if needed.

Dunlop vacuum pipes could have been used in place of gas pipes to avoid leakage.

Ideas To Be Implemented

The proposed technology has its scope in various fields

like Air conditioning, Refrigeration and cooling places etc.

Future Scope

Temperature drop is noticed but not as expected. Completely leak proof piping connection can perform

the expected task. This cooling system is practical and possible for mass

manufacturing.
