The invention provides a novel composite water production device. The novel composite water production device comprises a wheel-mounted dehumidifier, an air compressor, an air storage tank, a vortex tube, a heat preservation liquid storage tank, a component proportional divider, an air mixer, a centrifugal fan, a heat pipe, a heat dissipation air flue, an electromagnetic air valve and an electromagnetic water valve, wherein the heat pipe and the heat dissipation air flue are installed at the upper end of the air storage tank, and the electromagnetic air valve and the electromagnetic water valve are used for controlling a system to work. According to the novel composite water production device, water can be produced from air at a low temperature and low environmental humidity, pressure energy of the air compressor is fully utilized and converted into heat energy and low-temperature air energy, water in the air is gradually extracted by heat energy of compressed air through multiple links and multiple mechanisms, and energy generated in the operation process of various devices is comprehensively utilized. The novel composite water production device is suitable for producing water from air under an extreme condition, meanwhile, the storage environment of the obtained water is guaranteed, and the obtained water is hermetically stored at low temperature.
