  • Patent number: 7983016
    Abstract: An electrostatically atomizing device comprises an emitter electrode, an opposed electrode, cooling means for condensing water on the emitter electrode, and a high voltage source; and high voltage is applied to the condensed water so that minute water particles are discharged from a discharge end at a tip of the emitter electrode. The device comprises a controller for causing the charged minute water particles to be discharged stably. The controller has an initial control mode and a normal control mode. In the initial mode, the cooling means is controlled so as to cool the emitter electrode at a predetermined cooling rate. Once discharge current reaches into a predetermined target discharge current range, the cooling means is controlled by feedback control, on the basis of the value of the discharge current, in such a manner that the discharge current is kept within the target discharge current range.

  • Patent number: 7959717
    Abstract: An air conditioning system with an electrostatically atomizing function includes an electrostatically atomizing unit and a ventilation duct which flows conditioned air. The electrostatically atomizing unit generates a mist of charged minute water particles. The electrostatically atomizing unit is provided with a discharge port which locates adjacent to an air outlet of the ventilation duct. The mist of the charged minute water particles flows into an airflow which is sent from the ventilation duct. The mist of the charged minute water particles effectively spreads to the space by the air flow without dissipating inside the ventilation duct.

  • Patent number: 7837134
    Abstract: An emitter electrode is cooled by a cooler to generate condensed water which is charged by a high voltage applied between the emitter electrode and an opposed electrode and is discharged as a mist of charged minute water particles. A controller is provided to vary a temperature drop to a predetermined minimum temperature in dependence of an environmental temperature detected by a temperature sensor. The temperature drop is made variable in proportion to the environmental temperature. Accordingly, a sufficient amount of water can be condensed on the emitter electrode simply by controlling the cooling of the emitter electrode without relying upon an environmental humidity.
