Excerpt from Progressive Furnace Heating: A Practical Manual of Designing, Estimating and Installing Modern Systems for Heating and Ventilating Buildings With Warm Air
If you want to ventilate your room to warm it, and open the bottom aperture, you will succeed in both; because the fresh air will be the warmest, and will not stop until it comes in contact with the ceiling, where spreading out in a level strata over the whole ceiling, it will keep its relative position to the whole body until it reaches the bottom and passes out through the aperture. If we want to ventilate our room to cool it, we must let the air out at or near the top.
