Simplified Formula

The daily collected heat energy of solar collector in solar water heating system is calculated by the modeling of solar collector and stratified tank, and the result is verified by experiments. Through analysis of the calculation results, the simplified formula for calculating the daily collected heat energy is given. Using this simplified formula, the daily collected heat energy under different flow rates is calculated. The result shows that the daily collected heat energy of solar collector running in solar water heating system tends to stable when the flow rate above 0.005kg/(m2.s).

Evacuated Tube

The energy and the economic estimation for a passive solar water heating system under the Tirana climate conditions is performed. The trial system includes a heat pipe evacuated tube collector. To fulfil these objectives, measured values recorded every minute from the data logger of the system are used. The studied solar collector has a slope of 45° and is oriented 10° East from the South direction. The heat pipe evacuated tube collector has an aperture area of 1.476 m2. For an annual time period the irradiation on tilted solar collector area, the extracted energy from the storage tank, the delivered energy to the thermal consumer and the system efficiency were defined. Also, the economic assessment of the system is performed.

Solar Water Heating System

Solar water heating systems is one of the applications of solar energy. One of the components of a solar water heating system is a solar collector that consists of an absorber. The performance of the solar water heating system depends on the absorber in the solar collector. In countries with unsuitable weather conditions, the indoor testing of solar collectors with the use of a solar simulator is preferred. Thus, this study is conducted to use a multilayered absorber in the solar collector of a solar water heating system as well as to evaluate the performance of the solar collector in terms of useful heat of the multilayered absorber using the multidirectional ability of a solar simulator at several values of solar radiation. It is operated at three variables of solar radiation of 400 W/m2, 550 W/m2 and 700 W/m2 and using three different positions of angles at 0º, 45º and 90º. The results show that the multilayer absorber in the solar collector is only able to best adapt at 45° of solar simulator with different values of radiation intensity. At this angle the maximum values of useful heat and temperature difference are achieved. KEYWORDS: solar water heating system; solar collector; multilayered absorber; solar simulator; solar radiation
