Abstract
The software SOLSCALE was developed to predict calcium carbonate scaling in solar domestic hot water (SDHW) systems. It requires inputs of make-up water chemistry, system design specifications, water demand, and location. Scaling predictions are based on an equilibrium water chemistry model and a system operating temperature model. The equilibrium water chemistry model accounts for ionactivities, calcium complexes, and temperature dependencies in the equilibrium constants. Operating temperatures are interpolated from a database of representative values based on the location's weather, and the nondimensional variables SA/L (insolation x collector area/energy load) and V/Q (storage volume/daily load volume). The severity of scaling is predicted and recommendations are made toalleviate the problem when appropriate. SOLSCALE is available on 3 1/2' disks for PCs with Windows Version 3.1 or later.
