sir what are the basic heat source for designing of air-conditioning system in car and how to calculate the heat load due to forced convection of moving automotive body?
I think radiant heat gain, especially through all that glass, would be the largest load. The convection could be calculated accurately enough as convection over a flat plate. Then you have outside air being brought in and the heat load of the occupants.
Incoming heat load from sunshine, less that lost to the surroundings as a result of its moving, plus 120W per occupant.
