Description

112

The invention relates to air conditioning and can be used in the mining industry (in underground structures and mines).

The purpose of the Invention is the intensification of heat exchange with simultaneous saturation of the underground structure with atmospheric air cooled by supplying the cooled air from the surface to the drift.

FIG. 1 is a diagram of a device for conditioning mine air; in fig. 2 is a section A-A in FIG. one.

A tank 1 for cryogenic liquid is located on the surface of the mine, which is connected through the heat exchanger-evaporator 2 to the pipeline 3 for supplying the gasified product both to the consumer and to the mine. The heat exchanger-evaporator 2 is installed in the upper part of the air pipe 4, - which is located in the shaft 5 of the shaft and is fixed to the ground 6. In the same barrel 5 parallel to the air pipe charts42

Lena cage 7. The upper end of the pipeline 3 is brought to the consumer of cold, and the lower end is lowered into the mine and serves for various purposes, for example for the operation of pneumatic tools.

The air conditioning device in the mines operates as follows.

A cryogenic liquid, such as liquid nitrogen, from the tank 1 enters the heat exchanger-evaporator 2, where it is heated in the pipes, transformed;

gas that flows through conduit 3 to the cold consumer. Atmospheric air is sucked in the upper part of the air tube 4 with a specific gravity (and is cooled through the annulus of the heat exchanger-evaporator 2 and rushes down the air tube 4 with a specific gravity fj greater than. This air entering the shaft is used for ventilation and air conditioning.
