Well all of them would have failed GCSE physics then
Given that they are fridge engineers in particular, im amazed that they would make that mistake, as pressure is like HEAT, it is only viewed as moving from a high state to a low state.
Ie you dont add coldness to an item, you take away heat from it, likewise with pressure and airflow, if it moves from B to A then you dont say it gets sucked in form A to B, it gets blown from B to A.
