Abstract

The invention can be used for ventilation of rooms with excess heat. The purpose of the invention is to reduce the energy consumption of the device. Partitions 2 in housing 1 separate the flow and exhaust air streams. The device includes fans 3, 4, recuperative heat exchangers 5, 6, air heater 7, condensate drain pan 8 with drain pipe 9 and air inlet 10 of fresh air with louvers 11. The recirculation air treatment unit 12 includes a fan 13, two-position the air damper 14, the air intake and the air outlet 15, 16 of the recirculated air of the room with louvers 17, 18 installed in them. The hole 19 in the housing 1 communicates the air flow with the recirculation unit 12. The valve 14 is attached to the housing 1 with the ability to alternately overlap the holes 16, 19. Blinds 17, 18 are directed at an angle to each other. The heated room air is used to defrost the heat exchangers 5, 6. 2 or less.

Description

The invention relates to ventilation technology and can be used in plants in rooms with heat losses.

The purpose of the invention is to reduce energy costs.

FIG. 1 shows a device for ventilating a room; an air damper blocks the opening in the housing; in fig. 2 - the same, the air damper blocks the recirculated air vent.

The device for ventilating the area includes a housing 1, partitions 2 separating the supply and exhaust air, fans 3 and 4, recuperative heat exchangers 5 and 6, and air vents in the room are angled to each other, intensively mixed. This is ensured by the fact that the louvers 11 and 18 in the air outlets 10 and 16 are directed towards each other also at an angle.

When heat is exchanged between the outside air and the exhaust air in the recuperative heat exchangers 5 and 6, condensation may form, which collects 10 in the sump 8 and is then removed through the drain pipe 9.

Claims (1)

Invention Formula A device for ventilation of a room, comprising a housing, partitions, separating supply and exhaust air flows, fans, recuperative heat exchangers, an air heater and a tray for operation. The device operates as follows. ra condensate with a drainage pipe, air -. g - outlet air inlet with Blinds, characterized in that, in order to reduce energy costs, the device additionally contains a processing unit for the recirculation valve 14 blocks the opening 19 in the circulating air 40, which includes an additional 1 and opens the air outlet relative fan, a two-position exhaust 16. The outside air is supplied to the air damper, the air intake and the inflation by the fan 4 through the recuperative exhaust outlet of the recirculation air. Heat exchangers 5 and 6, and then through the air of the room with air outlet 10 and louvers 11. blinds, a hole in the casing installed in them. In the recuperative heat exchangers 5 and 6 at 5 the fresh air flows from the recirculated outside air to heat with the additional unit’s air, The position of the air damper 14 ensures the operation of the device in two modes. B the first mode (Fig. 1) air air removed from the room by the fan 3. The fan 13 takes in recirculated air, which is heated in the air heater 7 and is fed into the room through the air outlet 16 and louver 18. At the same time, the fresh air and air recirculation are placed in the additional unit. The Dipole valve is attached to the casing with the possibility of alternately blocking the opening in the housing and the air outlet of the recirculated air, and the louvers of the air outlet openings are angled to each other. the spirit is brought into the room at an angle to each other, mixing vigorously. This is ensured by the fact that the louvers 11 and 18 in the air outlets 10 and 16 are directed towards each other also at an angle. When heat is exchanged between the outside air and exhaust air in the recuperative heat exchangers 5 and 6, condensation may form, which is collected in the sump 8 and then removed through the drain pipe 9. If condensate freezes us In addition, the heated air of 30 This is used to defrost the heat exchangers 5 and 6. Invention Formula the air of the room with louvers installed in them, a hole in the body that communicates the supply air with recirculated air of the additional unit, In this case, the air heater is placed in the additional unit, the Duplex damper is attached to the housing with the possibility of alternately blocking the holes in the housing and the air outlet of the recirculated air, and the louvers of the air outlet holes are angled to each other.
