(54) DEVICE FOR HEATING PREMISES

At a temperature within the design furnace, a direct action provides room heating on duty, and at a temperature below the design (up to the reference temperature of the corresponding climatic region), it provides additional heating of the air that has passed through the heat-storage furnace.

FIG. 1 depicted a room heating system using the proposed device; in fig. 2 is a variant of the structural embodiment of the device.

The device for heating the room 1 contains a heating unit 2 with a heat-storage furnace 3 and a heating unit 4 with a direct-action furnace 5 made with open heating elements 6. Each of the heating units is equipped with devices for separate control of the flow in the air ducts 7 and 8. The air streams created by the fan 9 or the backup fan 10 in the indicated channels are regulated by the flaps 11, 12. At the same time, the channel 8 connected to the furnace 5 is located outside the space occupied by the heater emulation elements 13 of the furnace 3.

The outlet section 14 of the channel 8 is located between the section 15 of the outlet of the furnace 3 and the section 16 of the entrance to the furnace 5. Between the output sections 14 and 15 of the air channels, an air flow control valve 17 is installed. This valve is spring-loaded from the side opposite to the outlet section 15 of the channel of the heat-storage furnace, and is installed with the possibility of closing the channel.

The adjustment of the valve position can be carried out both manually and automatically (not shown in the drawing).

The system provides for closed air circulation. The room temperature is monitored by sensor 18, which makes it possible to automatically maintain the temperature set at that time in the room.

The direct action furnace can be activated automatically by signals from temperature-sensitive sensors 18 installed in the room, and sensor 19 of air temperature in the chamber 20 before entering the furnace 5.

The circulation system is equipped with external air suction equipment and, if necessary, can be used for ventilation of the room.

The embodiment of the device shown in FIG. 2, characterized by the fact that in it a furnace 5 with direct action heaters is located above the heat-accumulation furnace 3. In this case, the partition 21, located between the heaters 2 and 4, has an opening 22 blocked by a valve 17. The furnace 5 is made with open heating the elements 6, and the heaters of the heat-accumulation furnace 3 are made in the form of rods 23 arranged in pipes 24 of the heat-accumulating material. The main air channel 7 passes sequentially through the chambers of both furnaces.

5 Areas of additional channels 8 are located between the heat-accumulating elements 25 and the thermal insulation of the furnace 26.

The furnace contains two pairs of additional channels 8. One pair of channels adjoins

10 heat insulation of the walls parallel to the planes 27 and the axes of the heaters, and the other to the heat insulation of the walls perpendicular to these planes. A duct 29 is located above the outlet 28,

15 intended for supplying heated air to a heated space. The return of air from the room and fresh air is carried out through pipeline 30. The furnace 3 is installed on the foundation 31, and for

0 reducing heat loss into the ground provides for thermal insulation 32.

As usually, the lower limits of temperatures corresponding to reference values for a given climatic zone are relatively

5 cutting, and the proposed device, in addition to the heat-storage furnace, contains a furnace with direct-action heaters, the heat-storage furnace of the device can be chosen to be higher than

0 reference design temperature. So, for example, at the point of the average climatic zone, where the reference minimum temperature is -30 ° C, the heat-retaining furnace can be selected for a design temperature of 15-17 ° C. When the ambient temperature is above -15-17 ° C, the standby heating is carried out periodically by switching on one air heater with a direct action furnace.

0 At the same time, the heat accumulative installation during the period of dips in the load grid of the power system is turned on and stores heat.

The heating of the room in the daytime is carried out with the heat-storage furnace off, due to the heat stored by the heat-accumulating elements. At a lower temperature, a furnace with direct action heaters can be used in the morning to accelerate the heating of the NIN room to the required operating temperature, as well as to heat the room in case of severe frosts. In this case, unit heaters may turn on during the lunch break.

5 The presence in the proposed device of a furnace with direct-action heaters reduces the size of the device and heat loss by 20-25%.
