Abstract- the use of renewable energy is on the rise worldwide because of the increasing demand of energy, high oil price and concerns of environmental impacts. But now days a highest progress of solar- powered air conditioning has increased. The air conditioning system is almost a must in every building because we want to good indoor comfort inside the building. This system focuses in the design and construction of a direct current (DC) air conditioning system integrated with photovoltaic (PV) system. It is consist of PV panels, solar charger, inverter and batteries. This system operated on solar energy and can be used in non-electrified areas. but we all known solar energy cost is effective ,renewable and environmentally friendly. Key Words: VASystem, Solar Energy, AC System,
1. INTRODUCTIONThe demand of air conditioning is increasing due to the effect of to change climate and global warming. the conventional electric air conditioning are electricity through generated from fossil fuels, and greenhouse gas emission would continuously worsen global warming; in turn the demand of air-conditioning would be further increasing. In subtropical cities, air conditioning is a standard provision for buildings. However, this type of are consumption of electricity in building. Air conditioning is defined as the simultaneous processing of temperature, humidity, purification and distribution of air current in compliance with the requirement of space needing air conditioning. In general, air conditioning which also can be known as refrigeration is defined as any process of heat removal. Solar energy one of the sources of renewable energy, solar energy is the most suitable system for installation for building and residential areas. This is most common globally and preferred type of thermally driven technology is absorption cooling. The system, is simple, capacity control, easy to implementation, highly reliable, easy to operation, long life and low maintenance etc.. the solar energy are most efficient and economic from cooling. But these systems are development and improvement of a normal air conditioner unit and it is operated by using electricity generated from the PV panels. After that to utilize solar energy and to run the air conditioning system is a practical technique to replace conventional electricity. In order to obtain a feasibility of the air conditioning system using solar, a lot research and testing have been initiated to learn and discover the design © 2017, IRJET

1.1 Solar Air Conditioning Solar air conditioning is the application of solar thermal energy (heat) to production of conditioned air through a thermally-driven refrigeration process.
1.2 Solar energy Almost all the renewable energy sources originate entirely from the sun. Photovoltaic solar energy conversion is the direct conversion of sunlight into electricity. This can be done by flat plate and concentrator systems. An essential component of these systems is the solar cell, in which the photovoltaic effect the generation of free electrons using the energy of light particles takes place. These electrons are used to generate electricity. Solar radiation is available at any location on the surface of the Earth. The maximum irradiance of sunlight on Earth is about 1,000 watts a square meter, irrespective of location. It is common to describe the solar source in terms of in insolation the energy available per unit of area and per unit of time (such as kilo-watt-hours per square meter a year). The ratio of diffuse to total annual insolation can range from 10 percent for bright sunny areas to 60 percent or more for areas with a moderate climate, such as Western Europe. The actual ratio largely determines the type of solar energy technology that can be used. The sun’s rays that reach the outer atmosphere are subjected to absorption, reflection, and transmission processes through the atmosphere before reaching the earth’s surface. Solar radiation is the world’s most abundant and permanent energy source. The amount of solar energy received by the surface of the earth per minute is greater than the energy utilization by the entire population in one year. Solar energy is referred to as renewable and/or sustainable energy because it will be available as long as the sun continues to shine. Estimates for the life of the main stage of the sun are another 4 – 5 billion years. The energy from the sunshine, electromagnetic radiation, is referred to as insulation.
