Indirect-direct compound evaporative cooling air conditioning unit with multilayer spray type plate pipes

Abstract

The invention discloses an indirect-direct compound evaporative cooling air conditioning unit with multilayer spray type plate pipes. The air conditioning unit comprises a unit casing, wherein an air inlet and an air supply outlet are respectively formed in the two opposite side walls of the unit casing; an air filter, a surface air cooler, a multilayer spray type plate pipe indirect evaporative cooler, a spray chamber, a filler b and an air feeder are sequentially arranged in the unit casing in the air movement direction; the multilayer spray type plate pipe indirect evaporative cooler is respectively connected with the surface air cooler and the spray chamber; an exhaust window is arranged on the top wall of the unit casing corresponding to the upper part of the multilayer spray type plate pipe indirect evaporative cooler; the exhaust window is connected with one end of an exhaust pipe; the other end of the exhaust pipe is opened, so as to form an exhaust outlet. The air conditioning unit can effectively improve the cooling effect by pre-cooling inlet air, performing multilayer atomization on spray water, improving materials and models of heat exchange tubes, arranging a rainwater collection unit on the top layer of the unit, and improving a secondary exhaust flow channel.

Description

technical field [0001] The invention belongs to the technical field of air-conditioning equipment, and in particular relates to a multi-layer spray type plate tube indirect-direct composite evaporative cooling air-conditioning unit. Background technique [0002] Evaporative cooling air-conditioning units generally adopt the form of indirect and direct evaporative cooling, coupled with air filtration, surface cooler pre-cooling, and supply / return air treatment, etc., its functions are becoming more and more complete, and its practical application has been continuously promoted and deepened. [0003] Today, a large number of actual engineering cases can prove that evaporative cooling air-conditioning units have unique application advantages, and as a healthy, economical, energy-saving and low-carbon friendly air conditioner, it is also known by more and more people. However, there are still some problems in some practical applications. For air-conditioning units with tubular ...

AI Technical Summary

Problems solved by technology

The tube-type indirect evaporative cooler using plastic round tubes is relatively large; the heat transfer performance of the tube-type indirect evaporative cooler using metal materials such as aluminum foil has been improved, but the efficiency is still not high enough; the tube-type indirect evaporative cooler using porous ceramic materials Although the cooler has many advantages, it is prone to bacteria and difficult to clean under humid conditions, and its cost is also high

In addition, the common indirect evaporative cooler adopts the method of spraying water in the secondary flow channel. When the unit is turned on, its circulating water pump continues to work. Returning to the circulating water pool, the energy consumption of the water pump is increased needlessly, and there are similar problems for the packing type direct evaporative cooler
