RU184580U1 - HEATED SUPPLY VENTILATION DEVICE - Google Patents

Abstract

The supply ventilation device with heating with a water coolant contains an air intake pipe located in the wall of the building, and an air channel with a heating element placed inside it, located along the internal wall of the building, as well as having an intake grille, a silencer, dust collector, consisting of at least 2 concentric tubes made of soft porous material (for example, isolon) connected by two or more spiral inserts of the same material, an anemostat, an automatic air vent and valve. The essence of the utility model consists in the fact that the heating element is made of corrugated pipe, which maintains its integrity when water freezes, thereby eliminating the possibility of defrosting the heating system and the use of a muffler-dust collector. Achievable technical result - the development of a simple and reliable design of the supply ventilation device with the supply air heated by a water coolant and protection against noise and dust.

Description

The utility model relates to the field of ventilation, and more specifically to supply air devices of natural ventilation and can be used to improve the quality of ventilation in residential premises, excluding the appearance of drafts.

From the existing level of technology known device ventilation (Patent No. 2439440, publ. 10.01.2012). The device comprises a nozzle mounted in a wall in which there is an intake grill on the outside. The incoming air is heated by supplying an air stream to a finned nozzle made of a material with high thermal conductivity, mounted on a heating radiator, above which a screen is made of sheet heat-insulating material with grooves made in it with ribbed nozzle elements passing through them.

The disadvantage of this device is the design complexity.

The closest analogue to the claimed utility model is a forced-air ventilation system with heat treatment providing automatic control of the supply air temperature. (Patent No. 72304, publ. 04/10/2008). The system consists of a supply duct with a heat exchanger installed in it. In front of the heat exchanger, an air distribution device made in the form of tiers cascaded and consisting of shelves with sides and steps is installed in the supply duct.

The disadvantage of this device is the difficulty of installing such a system in the wall of a building.

The task to which the claimed technical solution is directed is to create a forced-air ventilation system with heating that excludes the appearance of drafts in residential premises in the cold season, thereby increasing the comfortable living conditions of a person.

The technical result, which can be obtained using the proposed utility model, is reduced to the development of a simple and reliable design of the supply ventilation device with the supply air heating by the water coolant.

This problem is solved due to the fact that the ventilation device consists of an air intake pipe located in the wall of the building and an air channel located along the internal wall of the building. A valve can be installed at the upper end of the air duct. A heating element is placed inside the air duct. The intake pipe from the outer end is closed by an intake grille that prevents large debris from entering and may contain a silencer, dust collector, which prevents acoustic noise and dust from entering the room. Silencer - dust collector consists of concentric pipes made of soft porous material (for example, Isolon) connected by two or more spiral inserts of the same material. To adjust the supply air volume, an anemostat can be installed in the nozzle.

A distinctive feature of the proposed device ventilation is heated with a water coolant is a heating element made of corrugated metal pipe that is resistant to freezing of the coolant. In the upper part of the heating element there is an automatic air vent used to remove air from the heating system. The specified design of the heating element retains its integrity when water freezes.

The invention is illustrated by drawings, which depict:

In FIG. 1 is a cross section of a ventilation device,

In FIG. 2 is a frontal section of the supply ventilation device,

In FIG. 3 is a view A of FIG. 2

In FIG. 4 is an isometric view of a silencer-dust collector.

The forced-air ventilation device with heating with a water coolant consists of an air intake pipe 1 located in the wall of a building 2, closed on the outside by an intake grille 3, containing a silencer-dust collector 4, consisting of at least 2 concentric pipes 5 connected by two or more spiral inserts 6, and anemostat 7. An air channel 8 is installed on the inside of the wall of building 2, inside of which there is a heating element 9. An automatic collector is installed in the upper part of the heating element zduha 10. At the upper end of the air channel valve 11 is installed.

The device operates as follows. Cold air from the street due to the pressure difference through the intake pipe 1, passing through the intake grill 3, the muffler-dust collector 4, and the anemostat 7, enters the air channel 8. Then, the air moving down the air channel is heated from the heating element 9 connected to the heating system building, and enters the room. The valve 11 serves to distribute the incoming flow of air. Automatic air vent 9 prevents the formation of an air plug in the heating system.

Claims (1)
