Abstract: From past up to today motor vehicles use engine waste heat in order to warmup passenger compartment and to provide thermal comfort for the passengers.However,waste heat from the engine is sometimes not enough to provide required heat to the vehicle heating system especially in cold countries. In such cases, fuel burner heaters are very often preferred and used. When the coolant temperature is too low, then its temperature increased by burning fuel on the fuel burner heater and heated coolant is then pump to heat exchangers, located inside the passenger compartment, so that heating comfort is achieved. However, this proses both consumes extra fuel as well as increases exhaust emissions left to the atmosphere. On the other hand, when full electric vehicles are considered, which are increasing their shares in the market at every other day, because there is no internal combustion engine, there is no main heat source also. Hence, required heat has to be provided form the vehicle main batter

Abstract: In countries that are suffering from hot weather, a considerable part of energy is dedicated for cooling the buildings due to the absorbed part of the incident short-wave which results in an increase of the surface temperature of the roof.To overcome this problem, a bright (white) surface can be used to reflect the solar radiation.On the other hand, the Photovoltaic (PV) panels are widely used to convert the sun light into electricity. However, the dust accumulation either on the reflective materials or on the PV panels will cause a substantial reduction on their performance. The present work is a dual-utility because it studies both the effect of dust deposition on the reflectivity of some surfaces and as well the effect of the cleaning process.
