SU340A1 - Method of heating with hot air - Google Patents

Description

For room heating, the author proposes a system in its structure resembling ordinary steam or water heating, but with the replacement of a heated fluid — heated air at high temperatures, which is channeled through a fan action or natural circulation to a heated room. special heating devices and, after cooling, is returned to the heater through the reverse system of channels for heating.

To achieve the intended goal, it is necessary to install a heater for heating the air, whereby the heating surfaces in the heater are made of metal for better heat transfer to the heated air, and the outer shell of the heater is made of evil heat conductors. In order to hygienic, the heating devices in the rooms are made of materials that strongly absorb heat and slowly transfer it to the surrounding air of the heated room.

FIG. 1 shows a diagram of a gas pipeline from the heater A to the room; in fig. 2 and 3 depict heaters in a section and in a perspective view.

The design of heating appliances can be quite varied: either as a thin brick, concrete or stone wall located directly along the walls of the room (Fig. 2) or at some distance to increase the heating surface of the appliance, or as a conventional type of Dutch or one-turn furnace, through the channels of which hot air is passed from a common heater, or in the form of sectional devices (Fig. 3), such as radiators made of any stone materials (for example, brick, concrete, ceramic pipes, unfired lines, etc.), or, finally, in the form of a series of channels located in the niches of the walls, under the surface of the stone floor, etc.

Due to the significant heating of the air in the calf-sphere (up to 150-200 c.),

it is necessary that the walls of the heaters be of sufficient thickness and not be heated above 60 ° C. on the side in contact with the room air.

To regulate the degree of heating of heating devices, regulators in the form of rams, valves, blinds, etc. are inserted into the flow channels. The heating devices are connected to the general heater with the help of channels carried out in walls j of the room and calculated so j air circulation in the system was | natural, based on the difference I of air densities of different temperatures, similar to the system of water or | - steam heating, or air movement through the system is carried out with j help of the fan, which is supplied in a central air duct, near the heater.

In order to ensure the safety of the proposed heating when using such heated air, the author suggests wearing all the channels and appliances inside with a solid casing made of roofing iron.

SUBJECT OF INVENTION.

A method of heating with hot air, characterized by the use of a closed, not communicating with heated premises, system of ducts designed for independent or with the assistance of an air circulation fan that is strongly heated (up to 150 - 200 ° C.) by the heater ducts and local heaters returning to the heater.
