I can think of a couple of options:
1. Create a vestibule. This is essentially a small room, like a mudroom, between the conditioned space and the unconditioned space.
2. Use an 'air curtain'. You've probably experienced this technique in big box retail stores, as you walk in, you'll feel a strong gust of air from overhead. This creates positive air pressure, preventing the unconditioned outside air from entering the store.
the air in a fridge when you open the door gets hotter because you let the particles out
I think it would be open the door.
Cold air. Cold air is heavier than warm air so when you open the fridge door the cold air 'drops' out of the fridge onto the floor.
A closed door constitutes a physical barrier to the movement of air; an open door permits the movement of air.
The air was whistling as it passed through the open door
If you are equipped with a parachute, you can open the door of a plane in midair and jump out, but if you don't have a parachute there is not much you can accomplish by opening the door while the plane is still in the air. Once the plane is on the ground, you are of course free to open the door and leave. what are you a terrorist why are you trying to open the door on an air plane what are you going to do plant the bomb and jump out?
It was not designed to open in mid-air and have nescessary precautions such as the door frame being actually bigger than the door. However, it is still possible and if accomplished, it will risk the 777 breaking up in mid-air
the blend door may not be operating properly, or a vacuum leak may be present.
Could be, Stuck open thermostat, Low on coolant, Plugged heater core, Temperature blend door actuator malfunction.
It's probably the air recirculation door. When the door is closed, it circulates the air inside the car. When it's open, it allows outside air in. Even with the door closed, you will still get some outside air in.
I have never heard of Air Bag chimes. There is seat belt, lights on, door open, but no air bag chime, as far as I know. I suggest you visit your local Ford dealer, for an answer.
Behind the glove compartment door. Open and empty the glove compartment door then remove the two door stop/bumpers to allow the door to drop down. This will expose the cabin filter access door. Remove the cabin filter access door and the cabin filter will slide out easily.
