Abstract

The invention relates to the technique of ventilation and air conditioning and allows an increase in the degree of utilization by reducing the aerodynamic resistance of the intake channels (PCs). The axis 9 of rotation of the shutter 8 is located across the PC 2 on the side of the exhaust pipe 7 of the exhaust air. The height of the flap 8 is less than the height of the PC 2. To eliminate the possible freezing of the channels, part of the PC 2 is blocked by the gate 8, while the warm exhaust air flows into the channels 3 adjacent to the closed PC 2 channels, which provides defrosting of the blocked PC 2. PC 2 frosting at the lowest possible negative t-re supply air, while another part of the overlapped PC 2 outside the frost zone is open for the passage of fresh air. When the frost zone is reduced, the flap 8 partially rotates around the axis 9 and overlaps only the frost zone. 2 pcs. / i (Л 1 /: с ю ю со. 9.2

Description

t

The invention relates to air conditioning and ventilation technology and can be used, in particular, for the utilization of heat energy from exhaust air.

The aim of the invention is to increase the degree of utilization by reducing the aerodynamic resistance of the supply channels.

Fig. 1 is a schematic diagram of a device for utilizing thermal energy with a flap adjacent to the intake ducts; in Fig.2 the same, turned relative to the inlet of the intake channels.

The device for utilization of heat energy comprises a housing 1 with a cross inaccurate alternating supply and exhaust ducts 2 and 3, communicated with supply and exhaust connections 4 and 5, 6 and 7 of supply and exhaust air with co-emitters.

The valve 8 is mounted for movement across the supply channels 2 and partially overlaps them.

In addition, the valve 8 has the ability to rotate around an axis 9 located across the inlet channels from the side of the exhaust pipe 7 of the exhaust air, and is made less than the height of the inlet channels 2.

A device for utilization of thermal energy works as follows.

The use of the present invention allows a substantial increase. to increase the degree of utilization of the heat energy of exhaust air by reducing the aerodynamic resistance of the overlapped supply channels and increasing the heat exchange surface

and exhaust cooled air is supplied through supply pipe 5, pro-35 between the supply ceilings goes through exhaust channels 3, where exhaust air gives heat through the heat exchange surface (not shown) to supply air and then

Invention Formula branch pipe outlet ha. The heated intake air is supplied through the inlet nozzle 4, passes through the inlet channels 2, where it receives heat through the heat exchange surface from exhaust air, and then enters through the outlet of the 1st inlet 6 inlet air into the room. With cross-flow of supply and exhaust air flows and negative supply air temperature in the zone of supply air intake and exhaust air outflow, exhaust channels 3 may freeze. To eliminate frosting, part of the intake ducts 2 is blocked by 7 exhaust air. energy, containing a housing with alternating supply and exhaust canals; 1 terminals connected to the corresponding inlet and outlet pipes of the supply and exhaust thawing air, and the damper, installed with the possibility of moving across the inlet channels and partially overlapping them, characterized in that, in order to increase. the degree of utilization by reducing the aerodynamic resistance of the inlet channels, the damper is installed rotatably around an axis located across the inlet channels on the side of the exhaust air exhaust pipe, and has a height less than that of the inlet channels. O five puff 0 five 0 while the channels 3 adjacent to the blocked channels 2 receive warm exhaust air, which ensures the breaking of the closed channels 2, After defrosting part of the channels 2, the flap B moves across the supply channels 2 and overlaps the part of the subsequent channels 2 where defrosting is also performed. The shutter 8 has a height lower than that of the intake channels 2 and ensures that only the freezing zone of the channels 2 overlaps with the lowest possible supply air temperature, while another part of the blocked channels 2 outside the freezing zone is open to allow the intake air to pass. When the intake air temperature increases, the frosting zone of the intake ducts 2 decreases, so the flap 8 partially rotates around the axis 9 towards the intake air and blocks only the frost zone, freeing up most of the intake ducts 2 for air passage, The use of the present invention allows a substantial increase. to increase the degree of utilization of the heat energy of exhaust air by reducing the aerodynamic resistance of the overlapped supply channels and increasing the heat exchange surface and exhaust between the ceilings of fresh air, between the ceilings of fresh air, Invention Formula 50 thawing air, and the damper, installed with the possibility of moving across the inlet channels and partially overlapping them, characterized in that, in order to increase. the degree of utilization by reducing the aerodynamic resistance of the inlet channels, the damper is installed rotatably around an axis located across the inlet channels on the side of the exhaust air exhaust pipe, and has a height less than that of the inlet channels. 0) (lo daepshy bozduh 60 Editor L.
