As shown in fig. 1, the utility model provides a refrigerating plant with dehumidification function, including first water conservancy diversion fan 1, refrigeration cabin 2, header tank 3 and second water conservancy diversion fan 4. The air outlet of the first diversion fan 1 is connected with the air inlet of the refrigeration cabin 2. In order to improve the energy efficiency of the refrigerating cabin 2, a tunnel air pipe is arranged underground corresponding to the refrigerating cabin 2, one end of the tunnel air pipe is connected with an air inlet of the first guide fan 1, and the other end of the tunnel air pipe is communicated with the air of the working space through the louver box 6. In addition, in order to further improve the heat exchange effect and reduce the energy consumption, the tunnel air duct is further provided with a heat exchange device, and the heat exchange device divides the tunnel air duct into a first tunnel air duct 500 close to the louver 6 and a second tunnel air duct 501 far away from the louver 3. The heat exchange device 7 can be a tubular heat exchanger 7, the tubular heat exchanger 7 is communicated with underground well water through a water pump 8, so that the water pump 8 can pump the underground well water into the tubular heat exchanger 7 as a heat exchange medium, and the temperature of the underground well water is lower for a long time, so that the air is cooled by the underground well water, the cooling effect is good, and the energy consumption caused by cooling the heat exchange medium can be reduced. When the first guiding fan 1 works, the air in the working space is absorbed from the louver box 6, the air in the working space firstly enters the first tunnel air duct 500, exchanges heat with soil in the stratum in the first tunnel air duct 500 to cool, enters the tubular heat exchanger 7 to be further cooled by underground water, then exchanges heat with the soil in the stratum in the second tunnel air duct 501 again to cool, and finally enters the refrigerating cabin 2. Since the air entering the refrigeration compartment 2 from the first induced draft fan 1 is cooled in the ducted air duct and the tubular heat exchanger 7, the temperature of the air entering the refrigeration compartment 2 is relatively low, which greatly reduces the refrigeration pressure of the refrigeration compartment 2. In addition, in this solution, the temperature of the air in the working space that needs to be reached when entering the refrigeration compartment 2 can be increased by increasing or decreasing the length of the ducted air duct.
An air outlet of the refrigerating cabin 2 is connected with an air inlet of the second guide fan 4, and dry cold air prepared in the refrigerating cabin 2 is input into the working space from the second guide fan 4.

The water collecting tank 3 is also communicated with the tubular heat exchange tube 7 through the water pump 8, so that low-temperature liquid water condensed in the water collecting tank 3 can be pumped into the tubular heat exchanger 7 through the water pump 8 to serve as a heat exchange medium of the tubular heat exchanger 7, low-temperature water in the water collecting tank 3 is well utilized, and the purposes of energy conservation and consumption reduction are achieved.

When the temperature sensor 11 senses that the temperature in the refrigerating cabin 2 is higher than the preset temperature in the PID controller 13, the PID controller 13 controls the water pump 8 to pump underground well water or water in the water collecting tank 3 into the tubular heat exchanger 7 for rapid heat exchange so as to accelerate the temperature reduction of air; when the temperature sensor 11 senses that the temperature in the refrigerating compartment 2 is lower than the preset temperature, the PID controller 13 adjusts the resistance of the rheostat 12 to reduce the refrigerating efficiency of the semiconductor refrigerating chip so as to keep the refrigerating capacity in the refrigerating compartment in a balanced state.
