The invention relates to techniques for ventilation and air-conditioning.
The purpose of the invention is the reduction of energy costs on the circulation of the electroactivated water with bactericidal treatment of the air.
Known installation for bactericidal treatment of air, where, in particular, apply the spray, the electrochemically activated water into the irrigation chamber. By means of a pump through the nozzles (injector) in the air flow injected water received in an electrochemical activator by unipolar processing in an electric field of direct current . Part of the water (~3%) evaporates and, turning in the air, it moisturizes, gives it the properties of activated water, i.e., bactericidal activity.
The other (main) part of the water falls down into the sump chamber, where gravity comes in electrochemical activator. From the activator fluid is again pumped sprayed into the air stream with the purpose of heat-moisture treatment of air and giving him bactericides, i.e., carried out the principle of recycling electrochemically activated environment.
The disadvantage of this design is the increased consumption of electricity to drive the pump on the line Retz the mechanical injectors. Working pressure before the injectors may be 150-250 kPa [2, S. 195].
Also known for the design of heat and mass transfer apparatus with irrigated nozzle. The nozzle is used to create the surface of the contact phase when heat and moisture treatment between air and water. The nozzle is located inside the device, air flow is supplied into the lower part under the nozzle, water is sprayed from the top of the nozzle. As the nozzle used ceramic, porcelain ring process, plastic mesh, hygroscopic materials - aspen shavings, sheets of corrugated cardboard, etc., [2, 3].
Water for irrigation of the material of the nozzle is pumped at low pressure through a nozzle coarse spray , or through the perforated trays . Required in the network pressure at the pump is determined mainly by the height of water rise to the top of the nozzle. Typically, the pressure does not exceed (2-5) kPa [2, 201 S.], so the power consumption for the drive motor is substantially lower than in the above installation.

The disadvantages of devices with irrigated nozzle are:
1. Large hydraulic resistance to air flow when using Raschig rings or meshes.
2. Neboli using wood chips or corrugated cardboard. In the latter case, the deficiency should include low mechanical strength and a limited lifespan.
The technical result of the invention is to reduce the aerodynamic resistance of the air path (compared with irrigated tip) and the hydraulic resistance of the water line (compared to spray fluid into the irrigation chamber).
