Buildings.Fluid.SolarCollectors.Controls.SolarPumpController

Controller which activates a circulation pump when solar radiation is above a critical level

Information

This component models a pump controller which might be used in a solar thermal system. It controls whether the pump is active or inactive based on the incident solar radiation and the system parameters. The pump is activated when the incident solar radiation is greater than the critical radiation.

The critical radiation is defined per 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.
