Why heaters are placed near windows?
In: Physics
Other answers below are correct, but in general, you want the room to average out as much as possible to the desired temperature. So, you place your heat near where the room will be colder (near the window). In large commercial buildings, the air conditioner is typically set up to blow cold air toward the window, since the sun causes the window to be the greatest source of heat.
I have seen issues in the past where HVAC (Heating, ventilation, and air conditioning, the term used by those in the field) technicians who are used to setting up systems for offices with people cause problems in server rooms (or other areas with large heat-generating equipment) by trying to cool the OUTPUT of the racks/equipment. Their logic is to blow cold air at the hottest part of the room, to bring the room down to the desired temperature. (This makes sense for people, but not for equipment. People want to be comfortable all over, but equipment that uses fans/airflow to keep cool want cold air at their intake, and they do not care about how hot the rest of the room.)
