Abstract

This invention relates to the mining industry. The goal is to increase efficiency and safety at work. For this, a double-circuit heat exchanger 3 is placed on the surface and has an inlet 4 of the primary circuit communicated with the atmosphere. The heat exchanger 3 also has an outlet 5 connected to the air cooler 2 of the refrigerating machine 1. The air cooler 2 is connected in series with the inlet pipe 6 of the second circuit of the heat exchanger 3, the exhaust pipe 7 of the second circuit, the supercharger 8. Last communicated with the pipe 9 of the coolant, at the end of which are placed humidifiers 10 air. Air heated in the second circuit of the heat exchanger 3 with a low moisture content is supplied by a supercharger through a pipeline 9 to the conditioning zones. Before leaving the pipeline 9 dried air passes through the humidifiers. As a result of humidification, the air temperature drops. 1 il. Sw e

The invention relates to the mining industry and can be used for conditioning mine air.

The purpose of the invention is to increase the efficiency and safety of the device by reducing the hydrostatic pressure of the coolant.

The drawing shows a diagram of the air conditioning unit.

The device consists of a stationary chiller 1 with an air cooler 2, a dual-circuit heat exchanger 3 having an inlet 4 of the first circuit, communicated with the atmosphere, and a corresponding outlet of it 5, in series with the air cooler 3, an inlet of the b of the second circuit, an outlet of 7 second circuit, the compressor 8, placed on the surface. The compressor 8, in turn, communicates with the coolant pipeline 9, at the end of which the air humidifiers 10 are located.

The device works as follows.

A vacuum in the path of the primary and secondary circuits of the heat exchanger 3 is created by the air blower 8. As a result, atmospheric air flows through the nozzle A into the primary circuit and, as it passes, into the air cooler 2 of the refrigerating machine 1. The air cooler 2 cools the air. water in it. Condensed moisture is removed from the tract. The cooled and dried air enters through the inlet pipe 6 into the second circuit of the heat exchanger 3, where heat is exchanged with the air passing through the primary circuit and its cooling, which is also accompanied by condensation of moisture.

The resulting condensate is also removed. As a result, air is pre-cooled and dried in the primary circuit of the heat exchanger 3, the air cooler 2 enters. Air heated in the second circuit of the heat exchanger 3 with a low moisture content by the blower 8 is fed through the pipeline 9 to the conditioning zones. Before exiting the conduit 9, the dried air passes through the humidifiers 10, in which it is mainly humidified to 100% relative humidity. As a result of humidification, the air temperature drops.

The use of the proposed device leads to an increase in reliability and safety during the operation of the air conditioning system due to the absence of pipelines and high pressure heat exchangers.
