The chimney effect refers to a phenomenon that air rises upward along the channel 101, and air is forced to flow in a convection manner. Natural ventilation under the action of hot pressure generates air density difference due to the temperature difference of the air inside and outside the channel 101, so that pressure difference is formed, and the air outside the channel 101 tends to flow. The air with high temperature in the channel 101 rises due to the low specific gravity and is exhausted from the air opening at the top of the channel 101, and at this time, a negative pressure area is formed at the original place of the low-density air, so that the cold air with lower temperature and high specific gravity at the bottom of the channel 101 is sucked from the bottom of the channel 101, and the air around the channel 101 continuously flows to quickly diffuse or exhaust the cold air along the channel 101, so that the heat convection exchange is enhanced, and the indoor temperature rises more quickly.
