Abstract

The invention relates to a technique of ventilation and air conditioning. The aim of the invention is to increase the degree of utilization of exhaust heat and reliability. The ventilation unit comprises a cylindrical body 1, located in the latter with the formation of an annular gap 2, a heat exchanger 3, made in the form of a bundle of pipes 4 with an annular space 5. The inlet nozzle 6 of supply air through the circuit 7 of the fan 8 of the axial type and a bundle of pipes 4 communicates with the output the supply air pipe 9, and the exhaust air inlet pipe 10 through the annular gap 2, the annular space 5 and the fan circuit 11 of the fan 8 - with the exhaust air outlet pipe 12. In the annular gap 2 perpendicular to the tube bundle 4 there is an annular partition 13 with the possibility of its movement along the latter and with the formation in the annular gap 2 of two flow cavities 14 and 15. The inlet 10 of exhaust air communicates with the outlet nozzle 12 successively through the flow cavity 14 of the annular gap 2, annular space 5 and the flow cavity 15 of the annular gap 2. 1 Il.

Description

The invention relates to the technique of ventilation and air conditioning.

The purpose of the invention is to increase the degree of utilization of exhaust heat and reliability of operation.

The drawing shows a schematic diagram of the ventilation system

The ventilation unit comprises a cylindrical body 1, located in the latter with an elongation of the annular gap 2, a heat exchanger 3, made in the form of a bundle with annular space &. The supply air inlet 6 through the corresponding circuit 7 of the axial-type fan 8 and the bundle of pipes 4 communicate with the supply air outlet 9 and the inlet 10 of the exhaust air through the annular gap 2 and the annular space 5 and the corresponding circuit 11 of the fan 8 - with the output pipe 12 exhaust air.

In the annular gap 2 perpendicular to

roooLl n is an annular junction 13 with the possibility of its movement along the latter and with the formation in the annular gap 2 of two flow cavities 14
