about

Supply air 6 and 7 with longitudinal heat exchange tubes 8, laid in box 3, connected to manifolds 6 and 7, inlet pipes 9 and 10 with flaps 11 and 12 installed in them, while pipe 9 is connected to the outside air inlet 13, and pipe 10 - with distributing air ducts located in the room 14. The device is equipped with longitudinal partitions 15, rotary guides 16 and 17 and air distribution pipes, while the heat exchange tubes 8 are placed along the entire height of the duct 3, ki 15 are arranged between the heat exchanger tubes 8, and the rotary guide yuschi 16 and 17 - in the manifolds 6 and 7 parallel to the partitions 15 to form a vertical labyrinth of alternating between a supply and rip channels 19. Baffles 18 and 15 are installed with a bias.

The device works as follows.

In the initial period of growing the young with the minimum required volume of exhaust using the exhaust duct 3 with the booster 4 tons, air from the cell batteries 1 is pumped through the perforated wall 2 into the exhaust duct 3 and moves, washing the heat exchange tubes 8 along the bulkheads 15 upwards . In this case, the guides 16 are blocked, the outside cold air flows from the fan (not shown) through the dampers to the upper part of the collector through the upper zone of the heat exchange tubes 8 to the middle and lower zones and reassembles in the lower part of the collector 5, but from the opposite side of the cell battery and then flows through the air distribution pipes to the cell batteries 1. A heater 20 is installed in the collector 7.

Thus, counter-current movement of warm exhaust air from bottom to top and cold supply air from top to bottom is carried out. With a lack of heat in the cold period of the year, it is possible to reheat the supply air in the collector 7 by heaters 20 after passing it in heat exchange tubes 8,

The position of exhaust systems on the supply side of the cold air intake heat exchangers, as well as the presence of slide valves in the collectors, allows the intake and exhaust air to pass through the heat exchange zone in countercurrent, rather than cross current, which dramatically increases the heat recovery efficiency. Filling most of the ventilation duct with heat exchange channels increases heat removal in the ventilation unit. In addition, the implementation of partitions with a slope allows you to collect condensate on their surface and divert it into the condensate collector 5, mine most of the surface of the heat exchange channels, which leads to an improvement in their work. This is especially important in the initial period of young growth, when high ambient air temperature and high heat recovery efficiency are required. The proposed ventilation device allows to intensify the heat exchange and increase the efficiency of the device as a whole.

As the young grows and its mass increases, the overall need for fresh air increases, so that the flaps 9 are opened a little first, first from one and then from the other end of the cell battery, and air circulation is increased. The condensate formed on the surface of the pipes is collected on the walls 15, which have a slope, and from them flows into the condensate trap and is then led to the sewage system.
