ENERGY-SAVING HYDROHEATER Russian patent published in 2017 - IPC F24F5/00 

FIELD: heating, ventilation.

SUBSTANCE: invention refers to the ventilation equipment, particularly, to devices for air heating by means of latent heat of ice formation of water. The energy-saving hydroheater contains a shaft with tubes for external air input and supply air output and a water-spraying system with sprayers, whereupon, each sprayer contains hollow casing with a nozzle and a center hub; the casing is performed with a channel for liquid feed and contains a coaxial insert rigidly connected to the casing with the nozzle secured in its bottom part performed in the form of cylinder two-stage insert, the top cylinder stage of which is connected to the center cylinder hub by means of a thread coupling; the cylinder hub has a center through-hole and is installed with an annular gap relatively the internal surface of the cylinder insert, and the annular gap is connected to at least three radial channels performed in the two-stage insert; these channels connect the annular gap with an annular space formed by the internal surface of the insert and the external surface of the top cylinder stage, moreover, the annular space is connected to the casing channel for liquid feed, and in the bottom part of center cylinder hub, a hollow conical swirler is secured, the conical shell of which is fixed by means of at least three spokes secured with their first tips to the conical shell of the swirler, in its top part, and with their second tips, to an annular groove performed on the internal surface of the center cylinder hub; moreover, on the external surface of the hollow conical swirler, a screw thread is performed.

EFFECT: invention allows increasing of efficiency of the heating process of cold ambient air.
