JingHan Heating Course -1 Heating temperature gradient

Heating temperature gradient: In the heating process of the building, there is a change rate of 0.3-1.5℃ increase of indoor temperature as the building rises each meter with the height. This heating temperature change, with the heating medium temperature rise, the indoor temperature rise rate will have a greater change, this phenomenon is called heating temperature gradient.
