Keeping a spacecraft cool
Keep the spacecraft cabin cool without air. Pump heat to a radiator, change its orientation and watch how sunlight competes with radiation into space.

The model and its limits
Two thermal nodes, controlled thermal conductance and two-sided Stefan-Boltzmann radiation. Time runs 20 times faster. No convection, detailed pipe fluid dynamics, boiling or freezing model.
Equations used in the module
Equations Q_flow = K p (T_c-T_r); Q_rad = 2 A epsilon sigma (T_r^4-T_space^4); C_c dT_c/dt = Q_load-Q_flow; C_r dT_r/dt = Q_flow+Q_solar-Q_rad
