HYBRID COOLER Dipali Warhade,Kanchan Gujarmare,Priyanka Gadpale,Sunayana Somkuwar Department of Electrical,VidyaNniketan College of Engineering &tech, Rashtrasant Tukdoji Maharaj University, Nagpur ---------------------------------------------------------------------***--------------------------------------------------------------------INRTODUCTION The temperature mechanism within the human body Solar energy is radiant light and heat from the Sun that is maintains a body temperature of around 36.9 degree C harnessed using a range of ever-evolving technologies such (98.4degree F). But the skin temperature varies according to assolar heating, photovoltaics, solar thermal energy, solar the surrounding temperature and relative humidity.Fuel architecture, molten salt power plants and artificial deposit in the will soon deplete by the end of 2020, fuel photosynthesis The human body can be considered as scarcity will be maximum. Country like India may not have thermal machine with 20% thermal efficiency. The remaining the chance to use petroleum products. Keeping this 80% heat must be disposed off from the body to the dangerous situation in mind we tried to make use of nonsurroundings otherwise accumulation of heat results and pollutant natural resource of petrol energy. causes discomfort. The human body works best at a DIRECT METHOD OF UTILIZATION OFSOLARENERGY particular body temperature like any other machine but cannot tolerate wide range of variation in environmental temperature like thermodynamic machines.
The most useful way of harnessing solar energy is by directly converting it into electricity by means of solar photo-voltaic cells. Sunshine is incident on Solar cells, in this system of energy Conversion that is direct conversion of solar radiation into electricity.
AIMS AND OBJECTIVES Here will a solar panel which will give the output to the battery but sometimes there might be an increase in the intensity of the sunlight so there is a possibility of having damage to the battery.So here controller circuit will be used to provide constant voltage to the battery even when the intensity of the sunlight is high because when the intensity is high the solar panel will give double the voltage than it is required by the battery.This circuit will run pump and there will be filters attached to the pump.A charge controller, charge regulator or battery regulator limits the rate at which currents added to or drawn from electricbatteries.
In the stage of conversion into thermodynamic from is absent. The photo-voltaic effect is defined as the generation of an electromotive force as a result of the absorption of ionizing radiation. Energy conversion devices, which are used to convert sunlight to electricity by use of the photovoltaic effect, are called solar cells. PHOTOVOLTAIC\PRINCIPLES The photo-voltaic effect can be observed in nature in a variety of materials that have shown that the best performance in sunlight is the semiconductors as stated above. When photons from the sun are absorbed in a semiconductor, that create free electrons with higher energies than the created there must be an electric field to induce these higher energy electrons to flow out of the semiconductor to do useful work. A junction of materials, which have different electrical properties, provides the electric field in most solar cells.
It prevents overcharging and may prevent against overvoltage, which can reduce battery performance or lifespan, and may pose a safety risk.It may also prevent completely draining ("deep discharging") a battery, or perform controlled discharges, depending on the battery technology, to protect battery life.The terms "charge controller" or "charge regulator" may refer to either a standalone device, or to control circuitry integrated within a battery pack, battery-powered device, or battery recharger. NEED OF SOLAR COOLER Human beings give off heat, around an average of 100 kcal per hour per person, due to what is known as ‘metabolism’.
