SU658365A1 - Air humidifying device - Google Patents

Description

one

The invention relates to heating and ventilation technology and can be applied in residential and public buildings, in heated premises in which it is necessary to maintain a certain relative humidity (in hospitals, museums, administrative buildings, in warehouses).

Air humidification devices are known that are installed on heating devices and contain an evaporator connected by a pipeline to the internal volume of the heating device 1.

However, such devices have a low evaporative capacity when used on a sectional heating device, since the evaporator goes beyond the size of the device and during evaporation radiation heat is poorly used, as well as due to the frequency of filling the evaporator with water, which reduces operational reliability.

The purpose of the invention is to intensify the evaporation process and increase operational reliability when the heating device is sectioned.

This is achieved by the fact that the proposed device additionally contains a bimetallic valve installed on the pipeline, and its working body is inserted into the device, and the evaporator is placed between the sections of the heating device and made in the form of hygroscopic material suspended on the pipeline.

FIG. 1 shows schematically the proposed device, a general view; in fig. 2 bimetallic valve; in fig. 3 -

the proposed device, side view; in fig. 4 shows the mounting plate.

A device for humidifying air installed on a heating device I contains an evaporator 2 connected by pipe 3 to an internal volume of the heating device 1. A bimetallic valve 4 is installed on pipe 3 and its working member 5 is inserted into device 1. And the evaporator 2 is placed between sections 6 heating device 1 and is made in the form of plates 7 suspended from pipeline 3 from a hygroscopic material. Valve 4

consists of a seat 8, a sleeve 9, a rod 10 and a needle 11, which is fixed by the counter-cap 12. In the lower part of the stopper 13 of the heating device 1, a piston 14 is installed, which is connected to the plates 7 by means of the pipeline 3 of the holder 15 (the drawing shows one plate) . The holder 15 is attached to the device 1 on the suspension 16. The device for humidifying the air works as follows. When the heating system is turned on, the heating devices I warm up in the rooms, the temperature of the bimetallic valve 4 increases accordingly. 8 Because the sleeve 9 with the seat 8 is made of a material with a large coefficient of thermal expansion (for example, brass) relative to the rod 10, made with a small temperature expansion coefficient (e.g. Invar steel) of valve 4 is opened and the available air is discharged from the heater. With further increase in temperature. The water valve 4 opens even more, and the water, passing through the gap between the seat 8 and the needle 11 through the sleeve 9 through the hole in the plug 13 and through the fitting 14 through the pipe 3, flows into the middle part of the holder 15 and is absorbed by the evaporator 2 made of plates 7 of hygroscopic material. The evaporator 2 is bathed in an upward flow of heated air, and also receives heat in the form of radiation from the walls of sections 6 of the heating device 1, which ensures the intensification of the process of evaporation of moisture. The lower the outside air temperature, the less moisture in the air, and such air entering the room, due to infiltration and ventilation, reduces the relative humidity in the room. As the water temperature rises, the valve seat 9 bush 8 elongates accordingly, increasing the flow area of the water entering evaporator 2, respectively, and the amount of evaporated water increases in position. As the water temperature decreases, the flow of water to the evaporator 2 is reduced accordingly by shortening the sleeve 9 with the valve seat 8 and reducing the flow area for water. The even distribution of water to the evaporator 2, which has a relatively large surface, also intensifies the evaporation process, this is ensured by the fact that in the middle part of the holder 15 (where water is supplied) the gap between the pressing edges of the holder 15 is smaller than at the edges due to more nat ha clamps. Placing valve 4 in the upper part of the tube 13 of the heating device 1 provides more complete removal of air from it, increases the thermal performance of the device (heat transfer), and consequently, the convective movement of air increases, contributing to the intensification of moisture evaporation from a hygroscopic material - evaporator plates 7 2. When the water temperature drops to 2530 ° C, the sleeve 9 is shortened so that it provides a tight shut-off of valve 5 (shutting down the system for the summer period during repairs). The invention is a device for humidifying air installed on a heating device and containing an evaporator connected by a pipe with an internal volume of a heating device, characterized in that, in order to intensify the evaporation process and increase operational reliability when the heating device is sectioned, it additionally contains a bimetallic valve installed on the pipeline, and its working body is inserted into the device, and the evaporator is placed between the sections of the heating device and you It is filled in the form of plates of a hygroscopic material suspended on the pipeline.
