Waste_heat

Waste heat and air-conditioning heat removal aggregation for the urban canopy thermal column. Migrated from UrbanCanopy.jl@9200edd4 src/roof_wall_road_snow_temperatures.jl:440 (`WasteHeatAirConditioning` @component). Implements Oleson et al. (2010, CLM Tech Note Ch. 4) Eqs. 4.55-4.56: the unclamped total waste heat H_wasteheat_unclamped distributes heating/cooling fluxes from the roof and the two walls (sunlit and shaded) into the canyon air, weighted by the efficiency factors f_heat = 1/0.75 and f_cool = 1/0.25, the roof area fraction W_roof, and the canyon-wall geometry factor (1 - W_roof) * H_W per Eq. 4.55; this is clamped at H_wasteheat_max = 100 W/m^2 to produce H_wasteheat. The air-conditioning heat removal H_aircond is the sum of the three cooling fluxes (F_cool_roof + F_cool_sunwall + F_cool_shdwall) per Eq. 4.56. Parameterized as observed-only with three algebraic equations: H_wasteheat_unclamped, H_wasteheat, H_aircond are state variables; F_heat_roof, F_cool_roof, F_heat_sunwall, F_cool_sunwall, F_heat_shdwall, F_cool_shdwall, W_roof, H_W are inputs (parameters in standalone form).

Allocates the column-total anthropogenic waste heat (H_wasteheat) and air conditioning heat removal (H_aircond) to the pervious and impervious urban road surfaces under the CLMU urban canopy model. Migrated from UrbanCanopy.jl@9200edd4 src/roof_wall_road_snow_temperatures.jl:561 (`WasteHeatAllocation` @component). Implements Oleson et al. (2010, CLM Tech Note Ch. 4) Eq. 4.27: per the CLMU convention, waste heat and air-conditioning heat are deposited ONLY on the pervious and impervious road tiles (walls and roof receive zero by construction); each road tile receives the same per-unit-area flux equal to the column total divided by the non-roof areal fraction (1 - W_roof). Parameterized as observed-only with four algebraic equations: H_wasteheat_prvrd, H_wasteheat_imprvrd, H_aircond_prvrd, H_aircond_imprvrd are state variables; H_wasteheat, H_aircond, W_roof are inputs (parameters in standalone form).
