ABSTRACT

In India for the cooking purposes the conventional fuels are likely consumed more than the non-conventional fuels, and the household conventional fuels increase air pollution. By switching to the non-conventional way of cooking it is a way of reducing the household air pollution caused by conventional fuels. Solar is the one of the efficient way of cooking and heating purposes without pollution .The way of cooking is with the parabolic dishes, the concentrated solar rays is made to be focussed on the vessel placed nearby it, which in turn heats and cooks the meal placed in it. But the problem in solar cooking system is that the cooking is cannot be performed after the sunshine hours and people hesitates to adopt it for the fulltime cooking. The problem can be overcome by employing the phase change materials additionally when the vessel subjected to the sunrays the phase change materials which were surrounded to the vessel is also subjected to sunrays which melts the phase change materials and in turn absorbs heat up to maximum temperature of 372.5℃. The absorbed heat can be used after the sunshine hours particularly for evening cooking purposes, the heat absorbed during the sunshine hours is now liberated to cook the meal. Finally solar cooking is made flexible for the cooking purposes.
