Experimental Investigation of Solar Cooling and Heating Systems : 4th Report, Evaluations of Annual Performance by Simulation

Abstract

In this paper, the annual performances of solar heating and cooling systems for different values of system parameters are predicted by computer simulation. The prediction is based on the characteristics of solar collectors, absorption chillers, and so on that are reported in my previous papers. The system parameters varied in the simulation are the storage capacity, the collector area, the collector flow rate, the flow rate of hot water in the heating system, the flow rate of chilled water in the cooling system, and the slope angle and azimuth of the solar collectors. As a result of evaluating the values of the system coefficient of performance based on fossil energy, ε_S, under the various system parameters, it was found that a few parameters have the optimum value where the ε_S has a maximum.
