The invention discloses an intelligent air conditioning device and a control method. The intelligent air conditioning device comprises a shell, a bottom plate, a semiconductor refrigerating (heating) assembly, a processor module, a refrigeration chamber assembly, a drain pipe, an air guide pipe, a heat radiation chamber assembly and a bolt assembly. A semiconductor refrigerating piece and a spacer block are attached and combined and are overall inlaid in a heat insulation block to form the semiconductor assembly. The refrigeration chamber assembly comprises a refrigeration chamber, a water pan and a heat conduction fin set. The drain pipe is connected with the bottom of the refrigeration chamber. The heat radiation chamber assembly comprises a heat radiation chamber, a heat radiation chamber fixing plate and a heat pipe heat radiator. The refrigeration chamber and the heat radiation chamber are connected through the air guide pipe. The shell, the processor module, the refrigeration chamber assembly and the heat radiation chamber assembly are mounted on the bottom plate through the bolt assembly in an attached manner, wherein a flow guide hole is formed in the right side of the bottom plate. The processor module controls the working state of the semiconductor refrigerating piece, the working state of a heat radiation fan, the working state of a PTC heater and the working state of a wireless communication module in real time according to detected temperature and humidity through matching with set target parameters, and remote adjustment and control are achieved.
