I suggest to add the literals refrigeratedGoods and comestibleGoods to the list of loadTypes. The existing literal perishableProducts is quite similar, but not the same. Refrigerated goods require some special cooling system and a power connection on parking sites, for example.
refrigeratedGoods was accepted by TG, comestibleGoods was rejected.
refrigeratedGoods has already been added - presumably from promotion of Parking into the core model.
