Description

A graphical procedure was developed based on the f-chart design method to determine whether solar domestic water heating systems proposed for use in the HUD Hot Water Initiative Program have sufficient collector area to provide 50% of the load as prescribed by the thermal performance requirements of the Program. The procedure was specifically developed for the 11 states participating in the HUD initiative (the New-England and Mid-Atlantic States and Florida); however, it should be applicable for the sizing of the collectors for solar water heaters in other locations with similar climates. In the procedure, the collector area is first determined for a reference solar water heating system located in one of 25 locations. Area adjustment factors are then determined for a number of possible differences between the proposed system and the reference system. The required collector area is calculated as the product of the reference area and the area adjustment factors. The maximum difference in collector area calculated by the procedure and the area calculated by the f-chart computer program is less than 10%.
