Description

Technical Field

[0001] The invention relates to the technical field of tobacco production equipment, and in particular to a rapid temperature control device for a cigar tobacco leaf drying room. Background Art

[0002] The main function of a tobacco drying room is to dry the harvested tobacco leaves for subsequent processing and production. The drying room is usually equipped with tobacco leaf hanging racks or mesh racks to lay or hang the leaves flat so that air can circulate smoothly.

[0003] To achieve temperature and humidity control in the airing room, those skilled in the art often use (air-cooled) modular units (sets), also known as industrial-grade central air conditioners, such as the Midea brand modular unit model LSQWRFH65MA-C4. Specifically, those skilled in the art often install a heat exchange assembly in the airing room, which includes a cold water coil and a hot water coil. They set up a circulating water flow to exchange heat with the cold and hot ends of the modular unit, so that the cold water formed is injected into the cold water coil, and the hot water formed is injected into the hot water coil. Temperature and humidity control is achieved through heat exchange between the heat exchange assembly and the air inside the airing room.

[0004] However, in the flow path setting of the circulating water flow in the prior art, the temperature of the hot water coil can only be adjusted by the modular machine during heating, or the temperature of the cold water coil can only be adjusted by the modular machine. In this case, the adjustment method is single and the adjustment efficiency is low. Summary of the Invention

[0007] The modular machine includes a heating end and a cooling end, and the exchange component is used to exchange heat with the air in the airing room; the exchange component includes a heat exchange component and a cold exchange component;

[0008] The hot water pipeline is a closed loop and passes through the heating end and the heat exchange component in sequence; a first water pump is provided on the hot water pipeline between the output end of the heat exchange component and the input end of the heating end;

[0009] The cold water pipeline is a closed loop and passes through the refrigeration end and the cold and heat exchange component in sequence; a second water pump is provided on the cold water pipeline between the output end of the cold exchange component and the input end of the refrigeration end;

[0010] When the first water pump is turned on and the second water pump is turned off, the water in the hot water pipeline can circulate through the cold exchange component of the cold water pipeline;

[0011] When the second water pump is turned on and the first water pump is turned off, the water in the cold water pipeline can circulate through the heat exchange component of the hot water pipeline.
