Temperature control structure of cigar tobacco leaf air-curing room

The utility model relates to the technical field of tobacco production equipment, in particular to a temperature control structure of a cigar tobacco leaf air-curing room, which is characterized in that a second front-end three-way piece is arranged on a cold water pipeline between the output end of a refrigeration end and the input end of a heat exchange component; a second rear end three-way piece and a second water pump are sequentially arranged on the cold water pipeline between the output end of the heat exchange assembly and the input end of the refrigeration end; the first front-end three-way piece is communicated with the second front-end three-way piece through a first bypass valve, and the first rear-end three-way piece is communicated with the second rear-end three-way piece through a second bypass valve; the air-curing room has the advantages that hot water can circulate in the hot water pipeline and the cold water pipeline or cold water can circulate in the hot water pipeline and the cold water p
