The invention provides an intelligent modular mine air-conditioning system, comprising a water storage tank, a water level sensor, a multistage immersible pump, a back-flush fully-automatic filter, aflow guiding pipe, a condenser module, an air return pipe and a refrigeration guiding pipe. The upper right wall in the water storage tank is connected with the water level sensor through screws, themultistage immersible pump is arranged in the water storage tank, and the upper right side of the water storage tank is connected with the back-flush fully-automatic filter through screws. Through arrangement of a filtering tube, a fixing cover, an impurity-preventing filter net, an adsorption core, a drainage pipe, a drainage pump and an underground water suction pipe, sucked-in underground wateris deeply filtered and adsorbed advantageously, the influence of blocking or impurity containing on the refrigeration efficiency is avoided, through the action of the drainage pump, the underground water is sucked out through the underground water suction pipe, the impurity-preventing filter net in the filtering tube and the adsorption core cooperate to adsorb and filter impurities, and then theunderground water can enter the water storage tank cleanly so as to facilitate subsequent refrigeration cycle work.
