Studying and Simulating Low Flow Floor Heating Solar System

AbstractBy process of time, and increasing demand for fossil,a tendency towards renewable energy started for different uses, the most important of which is: power generation, and water heating,by using solar power .Since, mostly, the average temperature for heating water given by solar power is [50CD],and radiators heating need water of [70-90 C°], temperature, as such floor heating is suitable in thermal applications.Radiant-floor heat is commonly designed for residential applications, where ventilation requirements are often met by operable windows, and cooling is not mandatory. Other applications include large open buildings, such as airplane hangars, where providing heat at the floor is much more cost-effective than heating the entire volume of air in the space. Water in the radiant-floor loop is often around [45C¡], depending on the floor finish. This is a lower temperature than forced hot-air systems, and reduces the energy required to heat the building. Buildings that have high ceilings, large windows, or high infiltration rates or that require high air change rates can save additional energy by using radiant floor heat.This research deals with the problems arising from the floor heating solar systems execution in concern with (large size of the storage tank and high cost of Constituent etc)The studied room exists in renewable energy lab in the Mechanical and Electrical Engineering Faculty-Damascus University. Heating load and the step between pipes were calculated, and a low flow was applied on both sides of the circuit which was connected to a stratification storage tank, finally the system was simulated by using Trnsys program
