FUNCTIONAL RELATIONSHIPS · NOT A WIRING DIAGRAM
Sum radiative exchange through insulation, support conduction, current-lead conduction, joint losses and dynamic losses during current changes. Evaluate each at the intended temperatures and operating modes. Cold-stage heat cannot be inferred from coil field strength alone or copied from the magnetic-nozzle study.
The coefficient of performance, COP, is cold heat removed divided by electrical input. It varies with cold-tip temperature, warm-end temperature and load. The reversible upper bound is Tc/(Th−Tc); real systems must be below that bound. The calculator checks this necessary condition, but being below it does not establish an available cooler or practical design.
The cooler warm end rejects the removed cold heat plus its electrical input. Our local radiator estimate adds auxiliary heat if those auxiliaries are assigned to the same thermal loop. It excludes battery losses, charging transients and unrelated station heat. Cold heat that originated elsewhere on the station must not be added twice to a station-wide energy balance.
Solar arrays seek useful sunlight; radiators need a favorable thermal view. Earth infrared, albedo, direct sunlight, obstruction and view factors all matter. The calculator uses an effective sink temperature as a simplified net-radiation boundary, not the temperature of empty space. Its area is emitting area, not automatically the planform area of a two-sided panel.
Surface research could change solar absorption or infrared emission, but no improvement is assumed in this budget. Candidate coatings must beat an established reference after spectral measurement, temperature cycling and environmental exposure. Cryogenic insulation and warm radiator coatings perform different jobs and need separate tests.
