A COMPARISON OF FLAT PLATE AND EVACUATED TUBE SOLAR COLLECTORS WITH F-CHART METHOD

Solar energy is used for variety of heating systems such as domestic hot water systems and industrial applications. The use of solar energy for domestic hot water and steam generation in industry is economical and environmentally friendly. "The F-chart" is a method that provides an easy way to determine the thermal performance of the solar heating and hot water systems. In this study, the solar systems are analyzed with the F-chart method in order to meet the hot water requirements of hotels. Annual fraction and heating loads for different solar collector areas and number of people is estimated. Flat plate and evacuated tube type collectors are compared and analysed.
