The invention relates to a dehumidifying module. The dehumidifying module comprises a wind heat exchanger, a compressor, a water heat exchanger, and a water storage case, wherein an outlet of the water heat exchanger is connected with the wind heat exchanger, a gas-water separation apparatus is arranged in the water heat exchanger, and a waterway of the water heat exchanger is connected with the water storage case. The dehumidifying module is capable of condensing moisture in gas to water through a cooling mode, so that moisture can be removed, an above process is realized through heat exchange at the dehumidifying module, the gas-water separation apparatus enhances the dehumidifying effect, the dehumidifying module has the advantages of simple structure, strong practicality, and industrial production.
