Description

(54) SUPPLY AND EXHAUST VENTILATION SYSTEM OF PREMISES

one

The invention relates to ventilation.

According to the basic author's certificate No. 798426, a supply and ventilation ventilation system of rooms is known, which contains an air duct connected to the rooms and an exhaust duct and supply ducts with control valves, and the last one connected to the fan inlet, and a bypass duct connected to the air duct ( connected by means of additional control valves to the inlet and outlet ducts, the outlet duct connected to the outlet of the fan fl1.

However, this system at low outdoor temperature requires a significant heat consumption for its heating.

The purpose of the invention is to reduce energy consumption.

This goal is achieved by the fact that a heat-accumulating nozzle is installed at the inlet duct at the inlet of the fan, and a heater is installed at the junction of the duct with an air duct.

FIG. 1 is a diagram of a ventilation system for supplying air to a room; FIG. 2 - the same in

10 period of removal of air from the room.

The supply and exhaust ventilation system of the premises 1 contains an air supply of water 2 connected to the premises and equipped with regulating valves 3 and 4 of the discharge and supply air ducts 5 and 6, the last of which is connected to the inlet 7 of the fan 8, and the bypass pipeline

20 9 connected to the air duct 2 and connected by means of additional regulators of the valves 10 and 11 to the inlet and outlet air ducts 6 and 5, the outlet duct 5 being connected to the outlet 12 of the fan 8, in the inlet duct 6 A heat accumulator is installed at the inlet 7 of the fan 8 at nozzle 13, and a heater 14 is installed in the bypass pipe 9 at the point of its connection with the air line 2. The supply and exhaust ventilation system of the rooms works as follows. Exhaust air from rooms 1 to the atmosphere is discharged with valves 10 and 3 open. At the same time, air from rooms through air duct 2, then through bypass pipeline 9 through valve 10, through the heat accumulator 13, is drawn in by fan 8 and is discharged by it to the air duct 5 through valve 3 to the atmosphere. The air, the passage through the heat storage chamber n 13, leaves most of its heat in it. The supply air in the room is provided with the valves 11 and 4 open and the valves 10 and 3 closed. At the same time, the supply air from the atmosphere through the supply duct 6 through the valve 4 and the heat-retaining nozzle 13 is drawn in by the fan 8 and supplied to them via KJioriidH II bypass line 9, through the heater 14, then through the air line 2 into the room. The passage through the heat-accumulating nozzle 13, the supply air is heated by the accumulated heat and, after passing through the heater 14, the heated air is additionally heated, providing the necessary temperature in the rooms. Thus, installation in the inlet duct of the heat accumulator of the nozzle, and in the bypass pipeline calorifier, will reduce the energy consumption of the system. Claims Injection-exhaust ventilation system of premises according to ed. St. No. 798426 is characterized in that, in order to reduce energy consumption, a heat accumulator is installed in the inlet duct at the fan inlet, and a heater is installed in the bypass pipe at the junction with the air duct.
