Abstract

SUMMARY OF THE INVENTION: A movable device with a supply air outlet oriented along the upper fence is installed under the upper fence. A fine distribution grid is located behind the outlet along the supply air flow. The grill is located in close proximity to the upper guard and outlet. 2 ill.

Description

The invention relates to ventilation and can be used in industrial and public buildings of various heights.

There is a known method of supplying ventilation to a room by supplying supply air to the upper area of the room with jetting jets onto the enclosure of the room.

The disadvantage of this method is the increased heat loss associated with an increased heat transfer coefficient:

a) with an increase in range, I feel that she has a range of fights. The range of range increases with an increase in the rate of expiration of the jets;

b) turbulent regime in the jet.

The closest in technical essence and the achieved result to the claimed method is the method of fresh air ventilation of the room by supplying fresh air to the upper zone with jets that are placed on the enclosure of the room.

The disadvantage of this method is, as in the previous analogue, increased heat loss. and therefore

energy costs to ensure a standardized temperature in the room, due to:

a) the turbulent regime of the laying jets;

b) increased air velocities in the jets, with an increase in their range, which leads to an increase in the heat transfer coefficient.

The aim of the proposed method of forced ventilation of the room is to reduce energy consumption by reducing the heat transfer coefficient.

Figure 1 shows a diagram of a forced ventilation system; Fig. 2 is the same, eg;: the location of the air intake in the center of the room.

The ventilation system of room 1 contains a feed device 3 installed under the upper fence 2 with the supply 4 outlet oriented along the upper fence 2 located behind the outlet 4 along the supply air flow, a clean distribution grid 5. F nrnpe emi

О about

The distribution grid 5 is located in the immediate vicinity of the upper fence 1 and outlet 4. Under the upper fence 2 of room 1, an air intake 6 is installed.

The ventilation system of the room operates as follows,

The air is treated (heated, drained, cleaned, etc.) and fed to the upper zone of room 1. Supply air passing through the distribution grids 5 at a certain speed is formed into a laminar flow (layer), which is laid on the upper fence 2, room 1 . Depending on the length of the guard 2, the thickness of the flow is determined. The supply air stream reaches the opposite wall of the room 1, swings along the wall, flows vertically into the working area of the room 1. When the supply air is released along the fence 2, in the central part of the room 1 flows

meet and enter the working area of room 1.

Supply air is prepared (processed) with a certain temperature, which, taking into account heat losses in the layer, ensures a normalized temperature of the air in the working area.

The supply of fresh air through a laminar flow along the enclosing surfaces reduces heat loss through the enclosure.
