VAPOUR ABSORBTION SYSTEM

OBJ: Develop and deploy new and renewable energy

for supplementing the energy requirements of the

country.

Ensure energy security, increase in the share of clean

power, energy availability and access, energy

affordability, and energy equity

About MNRE

• Introduction

• Utilization modes

• Refrigeration & Air Conditioning

CONTENTS

Introduction

• Soul of the modern world.

• Economics growth and technological.

• Three vital factors—economy, population and per capita

energy consumption.

• Green-house gas effect on the atmosphere’s ozone layer.

Solar Energy

• Time taken by light to come at surface of the Sun takes millions of years(this is

dependent upon mean free path considered) yet it reaches earth in about 8min.

• More energy in one second

than people have used since

the beginning of time.

• During nuclear fusion, the

sun’s extremely high pressure

& hot temperature cause

hydrogen atoms to come

apart and their nuclei to fuse

or combine.

Applications

• Photovoltaics

• Solar Thermal

• Solar Stills

• Solar Crop Dryers

ADVANTAGES AND DISADVANTAGES OF

SOLAR ENERGY

Renewable natural resource.

No carbon dioxide or other toxic emissions.

Solar thermal power to heat water or generate electricity

Not cost-effective in areas that have long periods of cloudy

weather or short daylight hours

The arrays of collecting devices for large systems cover

extensive land areas.

High voltage direct-current electricity

Various utilization modes

Factors

Ambient temperature

Latitute effect Wind speed Temperature recquirment

Direct normal radiation

Solar Energy

Clean efficient power that does not generate pollutants

• Reliability of continuous power without worry about brown/blackouts

• Easy installation since conduits and power lines are not required

• No monthly utility bills from your local power company

FLAT PLATE COLLECTORS

• Dark flat-plate

absorber

• Use both beam

and diffuse solar

radiation

• Do not require

tracking of the

sun

• Optical losses

• Thermal losses

EVACUTED TUBE COLLECTORS

• Thermo-

siphon

phenomenon

• Direct flow tubes.

• Heat pipe tubes.
