Solar energy in architecture: Novel facade collectors

optimum tilt angle of solar collectors and compare with collectors on the southern facade in tehran

nowadays two important discussions in academic parties all over the world are energy crisis and environment crisis. one of the strategies to deal with these crisises is using clean, renewable and domestic energy sources. one of the best renewable energies that can be used in different scales is solar energy. in iran which is considered among the greatest countries that receive huge amount of so...

Low Temperature Solar Collectors

Effect of Solar Angles on Incident Energy of the Flat Collectors

In this paper the daily, monthly, seasonally, and yearly optimum slope angles of solar collectors are determined for areas in Iran and new models are developed to calculate the monthly, seasonally, and yearly optimum slope angles for latitudes of to north. To achieve this purpose, the slope and surface azimuth angles of solar collectors for receiving maximum solar radiation were determined ...

Application of Solar Thermal Collectors to Improve the Energy Performance of the Fresh Air HVAC Systems

 In the preset study, the performance of a solar assisted heating, ventilation and air conditioning (HVAC) system in an operating theater building was studied. The yearly performances of the existing HVAC system and the system with the added solar collectors were simulated in terms of energy consumption and provided air conditions using a transient system simulation software (TRNSYS). In t...
