First, one needs to consider the relative air density of the substance. If it is heavier than air, it should be placed at a height of 0.3–0.6 meters above the ground; if it is lighter than air, it should be installed at the top. If its density is not very different from that of air, it is best to install it both above and below.
What standards or guidelines are used?
Please refer to the requirements of the Code for Design of Heating, Ventilation and Air Conditioning GB50019-2003
