.Buildings.Fluid.SolarCollectors.Controls.BaseClasses.GCritCalc

Information

This component calculates the solar radiation necessary for the fluid in the collector to gain heat. It is used in the model Buildings.Fluid.SolarCollectors.Controls.CollectorPump.

The critical solar radiation level is calculated using Equation 6.8.2 in Duffie and Beckman (2006). It is

G_TC=F_RU_L (T_In-T_Env) /(F_R(τα))

where G_TC is the critical solar radiation, F_RU_L is the heat loss coefficient, T_In is the inlet temperature, T_Env is the ambient temperature, and F_R(τα) is the maximum efficiency.
