SOLAR AIR CONDITIONING SYSTEM
The traditional air conditioner has three components: compressor, condenser and evaporator. The maximum amount of electricity is used by the compressor. The compressor consists of a low pressured gas named refrigerant (mostly CFC). This refrigerant with the help of electricity gets converted from low pressured gas to high energy hot gas. This hot gas then moves to condenser and dissipates all its heat there and converts into very cold liquid in the evaporator. This cold liquid is thrown out.
But in solar air conditioners instead of

This balloon consists of a valve which is used to ascend or descend it. To ascend the balloon valve is closed and to descend it valve is opened.
Researchers from NexPV along with French national center are doing research on solar balloon.

(7) According to them solar balloons when used with solar photovoltaic panels, hydrogen gas and fuel gas can produce electricity at night also. Solar balloon when combines with solar electricity, hydrogen gas is produced. This hydrogen gas can be used in fuel cells any time. (FIG2.2)
CONCENTRATING SOLAR POWER PLANT : These plants generate solar power by concentrating a large area of sunlight onto a small area by using mirrors or lenses. The concentrated sunlight produces large amount of heat. The heat is channeled through a conventional generator. This leads to the production of electricity. This electricity is used to run steam engines or turbines. The plants consist of two parts: the first part collects the solar energy and converts it into heat and the second part converts the heat to

SOLAR ENERGY AND ITS SUSTAINABLE USE IN COOLING IN INDIA
INTRODUCTION
With the steady increase in temperature and living standards of the people, there is an increase in the demand of air conditioners.
The traditional air conditioners use high amount of electricity and hence high amount of fossil fuels. On the other hand solar powered air conditioners use solar energy. Also solar powered ac’s have less negative environmental effects as compared to the traditional ac’s. They do not use CFC (chloroflorocarbons) as a refrigerant instead they use lithium bromide and ammonia which are water soluble. CFC’s have many negative impacts on environment. Solar conditioners do not make any noise. Most importantly they decrease the electricity requirements. As compared to traditional ac’s they are cheaper. They do not produce any green house gases.

SOLAR AIR CONDITIONERS
PRINCIPLE
A solar powered air conditioner works on four different principles:
1. Solar thermal cooling ac’s
2. Photovoltaic conversions
