FIELD: ventilation. ^ SUBSTANCE: device comprises heat exchanger-dryer made of air duct whose inlet is connected with the incoming air fan through the incoming air duct and outlet is connected with distributing air duct through the connecting air duct. The condensate collectors for collecting and discharging condensate underlie the air ducts. The chamber of intensive mixing is mounted downstream of the incoming air duct in the primary section of the heat exchanging air duct. The chamber is defined by the outer walls of the heat exchanging air duct and additional coaxially mounted air duct. The chamber of intensive heat exchange is provided with the bottom from the side of the incoming air duct. From the other side it is provided with the free outlet. The pressure duct with the delivery fan is mounted downstream of the bottom. The delivery air duct connects the internal space of the chamber of intensive heat exchange with the space of the stockroom. The outer wall of the chamber of intensive heat exchange is provided with pressure gauge connected with the starting system of the incoming air fan. ^ EFFECT: enhanced efficiency and reliability. ^ 2 dwg |
