  • The control unit of each water-production device controls the water-production function according to different working conditions in the external environment, data detected by the humidity sensors and the temperature sensors are summarized into the controllers, and the controllers adjust the air quantity by controlling the number (generally one to three) of operating fans and the operating speed of the fans, so that the optimal water production quantity is obtained, and water is produced through air purification and condensation in the most environment-friendly and energy-saving state. When the humidity of the external environment is low, the speed or the number of the fans is decreased, and the fans are even stopped; when the humidity of the external environment is high, the speed or the number of the fans is increased.
  • According to the embodiment of the invention, the evaporators are arranged on the two sides of the unit body of each water-production device, and the metal filter screens are arranged on the outer layer of each water-production device, so that ordinary sand and dust are isolated, the evaporators are protected, and the water production quality is improved; the evaporators on the two sides purify and condense air according to the air quantity for water production, and then condensate water is collected through the water collectors below the evaporators; when the water levels of the water collectors reach certain values, signals are emitted by the water level sensors and transmitted to the controllers, then the main control unit of the central control room is informed by the controllers, and the water pumps are synchronously started to pump the condensate water in the water collectors to a filter system.
  • The fans at the tops of the unit bodies pump air into the unit bodies from the outside of the evaporators, and the air passes through the condensers to cool high-pressure refrigerants; the air has already been cooled (with the temperature being lower than the outside temperature) by the evaporators after passing through the evaporators, and the cold air cools the high-pressure refrigerants when passing through the condensers; compared with a method for cooling high-pressure refrigerants through outside normal-temperature air, the efficiency is high; through the configuration, the size of the condensers can be reduced, the refrigeration systems are utilized more effectively, and the compression power is lowered; the system is more environmentally friendly and capable of saving more energy, and the water production quantity can be increased while the size of the unit bodies is reduced.
