Evaporative cooling air-conditioning unit with indirect riser-pull type packing layered spray compound

Abstract

The invention discloses a vertical pipe indirect and pull-out type filler layered spraying composited evaporative cooling air-conditioning unit. The evaporative cooling air-conditioning unit comprises a unit shell. The two opposite side walls of the unit shell are provided with an air inlet and an air supply outlet respectively. A primary filter, a vertical pipe indirect evaporative cooler, a low-temperature surface cooling unit, the pull-out type filler layered spraying direct cooler, a water baffle and an air feeder are sequentially arranged in the unit shell according to the flowing direction after air enters. A secondary air exhaust outlet is formed in the top wall of the unit shell in a position corresponding to the upper side of the vertical pipe indirect evaporative cooler. The evaporative cooling air-conditioning unit has the advantages of being small in size, high in refrigerating efficiency and not easy blockage of filler, and can meet the requirement for refrigeration in extreme weathers in summer.

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 with standpipe indirect-drawing type filler layered spray compounding. Background technique [0002] In recent years, with the improvement of people's quality of life and environmental awareness, how to effectively solve the existing two-stage evaporative cooling air-conditioning units with large volume, low efficiency, high energy consumption, difficult replacement of packing units, and inability to meet cooling requirements in extreme weather in summer The problem has become a key problem to be solved in the current evaporative cooling technology. Therefore, it is imperative to develop a new type of evaporative cooling air-conditioning unit. [0003] In the existing indirect-direct combined evaporative cooling air conditioning units, horizontal heat exchange tubes are generally used in the indirect eva...

AI Technical Summary

Problems solved by technology

[0003] In the existing indirect-direct combined evaporative cooling air conditioning units, horizontal heat exchange tubes are generally used in the indirect evaporative cooling unit, which occupies a large space of the unit and increases the volume of the entire air conditioning unit. The direct evaporative cooling unit generally uses dripping Water wets the packing, and the contact between air and water is not sufficient, resulting in low cooling efficiency and high water-carrying rate of the air. In long-term use, the packing is easy to block and difficult to replace; especially in extreme weather in summer, The cooling capacity of this air conditioning unit is often not up to the requirement
