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.

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

  • The Pros And Cons Of Standard Air Conditioner

    962 Words  | 2 Pages

    Standard Air Conditioner There are a number of standard air conditioner systems that are available on the market. One is a unitary system. The one room air conditioners sit in a window or wall opening, with interior controls. A large house or building may have several units, permitting each room to be cooled separately. Another type is the basic central air conditioning unit, which offers whole house-house cooling. It is usually a large, loud, mechanism that sits outside of the home. Although these standard air conditioners may be effective, they come with drawbacks. According to the U.S. Department of Energy, Americans spend $22 billion a year and use more than 183 billion kilowatt-hours of electricity to cool their homes with standard air conditioning. Also those air conditioners release about 100 million tons of carbon dioxide into the air annually -- two tons for each home that has one.

    In warmer climates such as Egypt they used techniques as evaporative cooling, “if water is placed in shallow trays during the cool tropical nights, its rapid evaporation can cause ice to form in the trays, even if the air does not fall below freezing temperatures”. Although refrigeration developed in the 18th century it wasn’t until the mid-19th century when the first refrigerator built using vapor technology was build by American John Gorrie in 1844. A few years later commercial refrigeration was introduced as well as vapor compression technology which was the beginning of our modern refrigeration. Later that century ammonia was popularized as the evaporation chemical in refrigeration. All the trials and tribulations of refrigeration where all stepping stones to the 20th century and the introduction of modern refrigeration as we know it

  • Solar Thermal Energy

    Solar thermal energy is dead! A solar thermal heating system can cost upwards of $7,000 to install and it most likely won't even save you too much money. This is why many people debate over whether they should use a solar thermal water heating system, because they think they are saving money, or an inexpensive traditional water heating system. A traditional heating system is a system that is powered off of electricity, gas, oil or some other fuel. A solar thermal heating system uses the energy from the sun, hence “solar”, and it turns that energy into hot water to either heat a home or to provide domestic hot water. The energy from the sun is captured by energy collectors, also known as solar panels. The water is heated inside the panels and then distributed throughout the home for use or stored in a tank for later use. The ideas behind this sound great, but in reality that is not the case.Solar thermal energy is not the best choice for home heating a home or hot water heating.

    In thermodynamics Refrigeration is the major application area, in which the heat is transferred from a lower temperature region to a higher temperature region. The devices which produce refrigeration are known as Refrigerators and the cycle on which it operates are called refrigeration cycles. Vapour compression refrigeration cycle is the most regularly used refrigeration cycle in which the refrigerant is alternately vaporized and condensed and in the vapor phase it is compressed. Gas refrigeration cycle is the well-known refrigeration cycle in which cycle refrigerant remains in the gaseous phase throughout the cycle. Cascade refrigeration are the other refrigeration cycles discussed in this chapter; absorption refrigeration is the one more refrigeration cycle which is used where the refrigerant is dissolved in liquid before it is compressed. One more refrigeration in which refrigeration is produced by passing the electric current through two dissimilar materials is called as the thermoelectric refrigeration.

    Regarding to solar power, Mistry claims that although the solar power does not generate pollution, it has a lot of costs. To built solar panels with a photovoltaic equipment has high costs. For instance, a photovoltaic system just for a home can cost around $35,000 (Kumar, 2012). However, if our goal for the future is to get a healthy environment, switch fossil fuels for solar power might be the best choice to achieve that goal. According to Kumar (2012), Solar power is a clean and renewable energy so, it decreases the dependency on fossil fuel and also reduces the air pollution. When the sun heats the panel, it generates clean energy which does not pollute the environment. All in all, the costs of solar power might not be applicable when it is certainly the best way for having a clean
