Evaporative cooling air conditioning unit provided with inertia filter and suitable for northwest districts

Abstract

The invention discloses an evaporative cooling air conditioning unit provided with an inertia filter and suitable for northwest districts, and the evaporative cooling air conditioning unit comprises an air inlet and an air supply outlet, a shutter, an inertial filter, a tubular indirect evaporative cooler, a direct evaporative cooler, a filler b and an air supply fan, wherein the air inlet and the air supply outlet are respectively arranged on the opposite lateral walls of a unit shell; the shutter is arranged on the outer side of the air inlet; the inertial filter, the tubular indirect evaporative cooler, the direct evaporative cooler, the filler b and the air supply fan are sequentially arranged in the unit shell according to the air intake direction; the shell wall, corresponding to the upper part of the inertial filter, of the unit shell is provided with a filter air exhaust port; the wall, corresponding to the upper part of the tubular indirect evaporative cooler, of the unit shell is provided with a secondary air outlet; and the wall, corresponding to the lower part of the tubular indirect evaporative cooler, of the unit shell is provided with a secondary air return port. According to the evaporative cooling air conditioning unit provided by the invention, through the optimization design of a filtering section, a tubular indirect evaporative cooling section and a direct evaporative cooling section by utilizing an evaporative cooling technology, the purification and heat transfer and mass transfer effects of the evaporative cooler are improved.

Description

technical field [0001] The invention belongs to the technical field of air-conditioning equipment, and relates to an evaporative cooling air-conditioning unit, in particular to an evaporative cooling air-conditioning unit with an inertial filter suitable for Northwest China. Background technique [0002] Evaporative cooling uses different contact forms of water and air to obtain cooling capacity by using the temperature difference between dry and wet bulbs of air under natural conditions. Therefore, the refrigerant used in evaporative cooling is water, not Freon, which pollutes the environment. Compared with traditional mechanical refrigeration equipment, evaporative cooling air conditioners can greatly reduce power consumption. Therefore, this kind of air-conditioning equipment, which is non-polluting to the environment, can effectively purify the air, cool down, and operate efficiently while effectively reducing the power consumption of the system, has attracted more and ...

AI Technical Summary

Problems solved by technology

Most of the filter devices used are coarse-effect filters. Although the coarse-effect filters can remove dust and purify the air, such filters are easy to use in places with large particles of pollutants such as the Northwest region where flying sand occurs frequently or mines. Blocked by sand and dust, the purpose of purification cannot be achieved well
