Problems solved by technology

High-pressure air jet cooling is to cool down the air after the compressed air expands. As long as a certain pressure is maintained, the expansion refrigeration function will not be lost. However, the sealing work must be done well in the mine. After the actual application of the project, it is found that there are some problems with the high-pressure air jet. , such as "dead angle" and "residual angle" and other issues

Abstract

The invention relates to a high pressure air injection-fluid power type water spraying chamber composite evaporative cooling air-conditioning unit which is characterized in that the side wall opposite to the shell of the unit is respectively provided with an air inlet and an air supply outlet; the shell of the unit is internally provided with a primarily efficient filter, a high pressure air injection cooling air device, a rotation type air flow equalization plate, a fluid power type water spraying device, a weir plate and an air feeder in turn in an air inlet direction; a novel air returningmixed section is arranged between the air inlet and the primarily efficient filter; and the side wall of the unit shell on the novel air returning mixed section is provided with an air returning port. According to the invention, high pressure air injection and fluid power type water spraying chambers are organically combined, and two direct evaporative cooling sections are used, thus the unit hasan obvious cooling effect on places in which indoor air needs to be cooled in quantity, such as industrial factory buildings and workshops based on high sensible heat, especially, mines.

Description

technical field [0001] The invention belongs to the technical field of air-conditioning equipment, and in particular relates to an evaporative cooling air-conditioning unit combining high-pressure air injection and fluid power water injection chambers. Background technique [0002] At present, the air conditioners used in underground coal mines at home and abroad are mainly mechanical cooling water cooling mine air conditioning, ice cooling mine air conditioning and air compression refrigeration air conditioning. These air conditioners mainly use the chilled water of the refrigerator equipment as the cooling medium, and then cool the air to the mining working face through the air cooler. The air cooler cools the air, and the arrangement on the coal mining ground is a centralized arrangement and a segmented arrangement. These two arrangements affect the cooling effect and economic effect of the mine. The evaporative cooling air conditioner known as "zero cost, green air cond...
