Description

technical field

[0001] The invention relates to the technical field of heating equipment, in particular to a convective heat exchange device based on a vortex ring for low-speed circulating air supply. Background technique

[0002] The heating source consumption of towns in northern my country accounts for 36% of the total building energy consumption in the country, and is the largest component of building energy consumption. The average energy consumption is 2-4 times that of developed countries with similar climates. When there is no one inhabited for a medium or long term, the heating is not stopped. When the heating is overheated, it is better to open the window than to close the valve. The waste of heat energy caused by these factors is as high as 20% of the total heat energy, worth tens of billions of yuan.

[0003] The initial cost of central heating in southern my country is very high, and the large-scale construction costs are high, making it difficult to centraliz...
