FIELD: ventilation.SUBSTANCE: conditioner comprises a section of receiving insulated valves, connecting sections, a section of the first heating, comprising heaters, valves and a bypass channel, the first recirculation section, a sprinkler chamber, where nozzles and drop catchers are installed. Underneath the sprinkler chamber there is a tray-filter, and downstream the sprinkler chamber there is the second recirculation section and a section of filters connected with the second heating section, comprising heaters and connected to a fan unit, the conditioner includes a valve of remote control in supply channels for supply of plenum air to a combined plenum and exhaust plafond installed in the room floor. The impeller of the plenum centrifugal fan via electric induction sliding couplings is connected to the electric motor. The impeller of the exhaust axial fan is also via electric induction sliding couplings connected to the electric motor, and heaters of the second heating are placed in bypass branches of plenum channels, where axial fans of the heater are also installed. In plenum channels there are valves of remote control, and automatic two-way valves are installed on the lines of coolant supply into heaters.EFFECT: higher efficiency and reliability of a process of automatic control.2 dwg |
