Abstract

Use: in refrigerators for storing perishable products. SUMMARY OF THE INVENTION: The system comprises a series of interconnected components: a single fan complex, an air cooler, a discharge manifold, and a series of parallel air distributing ducts (B). One of B is located near the floor of the room. In the explosive holes are made. The diagonal mesh partition forms a uniform distribution chamber in the container. The system is equipped with a second single complex, similar to the first, located in parallel and opposite it. The rows of explosives of both complexes are located in a vertical plane between the external enclosures and containers. The outlet openings are made on the side opposite to the outer enclosures. The explosives located near the floor are provided with guides inclined towards the floor, forming between themselves a longitudinal uniform slit. 3 il. cl

Description

The invention relates to the field of ventilation and can be used in loaded rooms, refrigerators for the storage of perishable goods.

The aim of the invention is to increase the uniformity of air distribution throughout the entire volume of the room.

The air distribution system in a loaded room with containers and external barriers (not shown) contains a series of interconnected and constituting a single complex fan 1, air cooler 2, discharge manifold 3 and a series of parallel air distributing ducts 4, 5, duct 5 located near the floor

(not shown) premises made in ducts 4, 5 outlets 6, diagonal mesh partition 7, forming a uniform distribution chamber 8 in collector 3. The system is equipped with a second single complex, similar to the first, parallel and opposite to it, with a row of ducts 4, 5 of both complexes are located in a vertical plane between the outer enclosures and containers, with the outlet openings 6 made in the air ducts 4, 5 on the side opposite to the external enclosures, and the air ducts 5 are located e close to the floor, are provided with guide 7 which are inclined towards the floor, forming between them a longitudinal slot 8 uniform, before headers 3 mounted regulators 9 airflow.

made of sheet steel or galvanized steel or asbestos cement slab.

The proposed system works as follows.

After cooling in the air cooler 2 of each complex, the ventilating outside air is supplied to the supercharger-collector 3 to the normalized temperature, where it is redistributed uniformly over its height and enters the air ducts 4 and 5. Air entering the air ducts 4 and outgoing through the exhaust holes 6, is intended for feeding directly into containers with products. The horizontal air supply from opposite sides allows for intensive uniform ventilation of a certain product layer practically along the entire horizontal plane.

 The aggregate distribution of air according to the height of the room in different horizontal planes creates its uniform distribution over the entire volume of the stack with the product.

From the air ducts 5, the air enters the room in the form of an air flow spreading on the floor, entering the space between the floor (not shown) and the containers of the first row, and is distributed over the floor space.

After ventilation of the perishable product, the air is removed from the room by means of uniform suction ducts (not shown).

To improve energy performance, the ventilation system works with

recycling the vent air removed from the room. The air is not thrown out, but enters the air cooler 2. In this case, the natural cold is partially used (air from the outside temperature is taken from outside the room).

Claims (1)

The invention of the air distribution system in a loaded room with containers and external fences, containing a fan, air cooler, and a discharge unit connected in series with each other. a collector and a series of parallel air-distributing air ducts, one of which is located near the floor of the room, holes made in the air ducts, is a diagonal mesh partition forming a uniform distribution chamber in the container, characterized in that, in order to improve the uniform distribution throughout the volume of the room, the system is equipped with a second single a complex similar to the first one, located parallel to and opposite to it, while the rows of air ducts of both complexes are located in a vertical plane between the outer fences and containers, the outlets being made in the air ducts on the side opposite to the external enclosures, and the air ducts located near the floor are provided with guides inclined to the floor forming a uniform longitudinal gap between them.  I FIG. sh eight FIG. 2 B-6 J.
