Mathematical model for the subsystem com- ponents like solar collectors, pumps, auxiliary heaters, heating and cooling loads, heat pumps etc. are modeled in terms of their ordinary differential or algebraic equations and validated experimentally [50].
Figure 2.2: Energy flow in solar collector
PL is the amount of power lost from the receiver to atmosphere through convection and radiation, where UL is solar collector heat loss coefficient in W/m2 oC and Tr is the temperature of the receiver in K.
Applying first principle of thermodynamics to the solar collector for open systems, useful power gain can also be written as rate of specific heat gained by the fluid.
