Performance improvement of solar hot water system by reducing solar irradiation from solar collector and solar tank
MetadataShow full item record
The word itself ―Solar‖ describes that we are dealing with some renewable energy source for a hot water system. The solar hot water system has been a popular throughout the world as it is cost effective and easy to maintain. The system is always successful when its efficiency level increases. This system efficiency level can be increased by reducing its heat loss A hot water system has been already designed, we need to do further implementation by working on its insulation at variable time, temperature and solar radiation so that there is a minimum temperature drop over night which in turn determined the operating temperature of the system. For this thesis we will be using an instrument named ―Pyranometer‖ which is a type of actinometer used to measure broadband solar irradiance on a planar surface and is a sensor that is designed to measure the solar radiation flux density (in watts per meter square) Depending on the temperature change of solar hot water system with respect to solar radiance, we will improve our insulation so that the temperature fall of 300 liters storage tank is only 2 degrees, which is the minimum temperature drop amongst any other stored water temperature.
